存储器目标(Target)是NAND闪存封装内的共享CE(,Chip Enable，芯片使能)信号的一个或多个逻辑单元(LUN，Logic UNit)。NAND闪存封装内可包括一个或多个管芯(Die)。典型地，逻辑单元对应于单一的管芯。逻辑单元可包括多个平面(Plane)。逻辑单元内的多个平面可以并行存取，而NAND闪存芯片内的多个逻辑单元可以彼此独立地执行命令和报告状态。The memory target (Target) is one or more logic units (LUN, Logic UNit) sharing the CE (Chip Enable, chip enable) signal in the NAND flash memory package. A NAND flash memory package may include one or more dies. Typically, a logic unit corresponds to a single die. A logical unit may include multiple planes. Multiple planes within a logic unit can be accessed in parallel, while multiple logic units within a NAND flash chip can execute commands and report status independently of each other.

存储介质上通常按页来存储和读取数据。而按块来擦除数据。块(也称物理块)包含多个页。块包含多个页。存储介质上的页(称为物理页)具有固定的尺寸，例如17664字节。物理页也可以具有其他的尺寸。Data is usually stored and read in pages on a storage medium. Instead, data is erased in blocks. A block (also called a physical block) contains multiple pages. A block contains multiple pages. A page on a storage medium (referred to as a physical page) has a fixed size, for example, 17664 bytes. Physical pages can also have other sizes.

在固态存储设备中，利用FTL(Flash Translation Layer，闪存转换层)来维护从逻辑地址到物理地址的映射信息。逻辑地址构成了操作系统等上层软件所感知到的固态存储设备的存储空间。物理地址是用于访问固态存储设备的物理存储单元的地址。在相关技术中还可利用中间地址形态实施地址映射。例如将逻辑地址映射为中间地址，进而将中间地址进一步映射为物理地址。In a solid-state storage device, an FTL (Flash Translation Layer, flash translation layer) is used to maintain mapping information from logical addresses to physical addresses. The logical address constitutes the storage space of the solid-state storage device perceived by the upper layer software such as the operating system. A physical address is an address used to access a physical storage unit of a solid-state storage device. In the related art, an intermediate address form can also be used to implement address mapping. For example, a logical address is mapped to an intermediate address, and the intermediate address is further mapped to a physical address.

存储了从逻辑地址到物理地址的映射信息的表结构被称为FTL表。FTL表是固态存储设备中的重要元数据。通常FTL表的数据项记录了固态存储设备中以数据页为单位的地址映射关系。A table structure that stores mapping information from logical addresses to physical addresses is called an FTL table. The FTL table is important metadata in solid-state storage devices. Generally, the data items of the FTL table record the address mapping relationship in units of data pages in the solid-state storage device.

FTL表包括多个FTL表条目(或称表项)。在一种情况下，每个FTL表条目中记录了一个逻辑页地址与一个物理页的对应关系。在另一种情况下，每个FTL表条目中记录了连续的多个逻辑页地址与连续的多个物理页的对应关系。在又一种情况下，每个FTL表条目中记录了逻辑块地址与物理块地址的对应关系。在依然又一种情况下，FTL表中记录逻辑块地址与物理块地址的映射关系，和/或逻辑页地址与物理页地址的映射关系。The FTL table includes multiple FTL table entries (or table entries). In one case, each FTL table entry records the correspondence between a logical page address and a physical page. In another case, each FTL table entry records the corresponding relationship between multiple consecutive logical page addresses and multiple consecutive physical pages. In yet another case, each FTL table entry records the correspondence between the logical block address and the physical block address. In still another case, the FTL table records the mapping relationship between the logical block address and the physical block address, and/or the mapping relationship between the logical page address and the physical page address.

支持Key-Value(键-数据，也简称为“KV”)存储模型的存储设备，提供基于键(Key)的读操作(Get(Key))与写操作(Put(Key,Value))。为执行写操作，主机向存储设备提供键(Key)与数据(Value)，以将数据写入存储设备，并将键作为所写入的数据的索引。为执行读操作，主机向存储设备提供键，存储设备根据键找到数据，并将数据提供给主机。因而在KV存储系统中，键是用来访问数据的索引，而数据(Value)是被访问的数据。一般地，键与数据的长度均不是定长。以及可选地，为了降低复杂性，键和/或数据的长度可具有指定范围。A storage device that supports the Key-Value (key-data, also referred to as "KV") storage model, providing key-based read operations (Get(Key)) and write operations (Put(Key,Value)). To perform a write operation, the host provides a key (Key) and data (Value) to the storage device to write data into the storage device, and uses the key as an index of the written data. To perform a read operation, the host provides a key to the storage device, and the storage device finds the data based on the key and provides the data to the host. Therefore, in the KV storage system, the key is the index used to access the data, and the data (Value) is the data to be accessed. Generally, the lengths of keys and data are not fixed lengths. And optionally, to reduce complexity, the length of the key and/or data may have a specified range.

图1B展示了现有技术的固态存储设备的地址转换系统的示意图。支持KV存储模型的固态存储设备的地址转换系统(也称为FTL表)提供从键到逻辑地址或物理地址的映射。可选地，FTL表中记录的逻辑地址或物理地址可以是数据帧(Data frame)的起始地址。数据帧是具有固定大小的数据单元，物理页包括1个或多个数据帧。FIG. 1B shows a schematic diagram of an address translation system of a solid-state storage device in the prior art. The address translation system (also known as the FTL table) of a solid-state storage device that supports the KV storage model provides a mapping from keys to logical or physical addresses. Optionally, the logical address or physical address recorded in the FTL table may be the start address of a data frame (Data frame). A data frame is a data unit with a fixed size, and a physical page includes one or more data frames.

键的长度可变，数据的长度也可变。键作为FTL表的索引。用键作为索引查询FTL表，得到对应的逻辑地址或物理地址。FTL表可以由数组、链表、树等多种数据结构实现。可选地，将不定长的键进行哈希运算，得到定长的哈希键(例如，4字节/8字节)，作为FTL表的索引。The key is of variable length, as is the data. The key acts as an index into the FTL table. Use the key as an index to query the FTL table to get the corresponding logical address or physical address. FTL tables can be implemented by various data structures such as arrays, linked lists, and trees. Optionally, a hash operation is performed on the variable-length key to obtain a fixed-length hash key (for example, 4 bytes/8 bytes), which is used as an index of the FTL table.

区域服务器提供多种服务，例如，符合指定条件的数据采集设备的查找，符合指定条件的存储设备的查找，符合指定条件的计算设备的查找，各种资源的注册服务；计算设备的应用程序的更新服务。区域服务器还提供符合指定条件的业务请求的处理，例如从视频或图像中查找符合指定条件的人物/物品，跟踪指定人物/车辆，绘制指定任务/车辆的运行轨迹，统计符合指定条件的人物/物品出现次数等。The regional server provides a variety of services, such as searching for data acquisition devices that meet specified conditions, searching for storage devices that meet specified conditions, searching for computing devices that meet specified conditions, and registration services for various resources; update service. The regional server also provides the processing of business requests that meet specified conditions, such as finding people/items that meet specified conditions from videos or images, tracking specified people/vehicles, drawing the trajectory of specified tasks/vehicles, and counting people/items that meet specified conditions item occurrences etc.

区域服务器根据收到的业务请求，采用例如映射-规约(Map-reduce)方式分发查询请求。例如，业务请求指示查找指定时间段内指定区域内具有指定特征的人物，区域服务器根据自己的数据库，获得指定区域内所有摄像头资源，根据各个摄像头资源，获取同摄像头资源对应的KV存储设备。区域服务器发送查询请求给各KV存储设备，也将处理查询请求所使用的应用程序信息发送给KV存储设备。KV存储设备的应用程序处理查询请求，并生成键(K)，从本地存储中获取同键(K)对应的值(V)作为查询结果，并将查询结果返回区域服务器。可选地或进一步地，应用程序从值(V)中获取原始数据，并对原始数据根据查询请求而进一步处理，将处理结果也作为处理结果。区域服务器汇总从各个KV存储设备获得的查询结果，把最终结果提供给客户端作为对业务请求的响应。The region server distributes the query request by using, for example, a map-reduce (Map-reduce) method according to the service request received. For example, the service request indicates to search for people with specified characteristics in the specified area within the specified time period, and the area server obtains all camera resources in the specified area according to its own database, and obtains the KV storage device corresponding to the camera resources according to each camera resource. The region server sends the query request to each KV storage device, and also sends the application program information used to process the query request to the KV storage device. The application program of the KV storage device processes the query request, generates a key (K), obtains the value (V) corresponding to the same key (K) from the local storage as the query result, and returns the query result to the region server. Optionally or further, the application program obtains the original data from the value (V), and further processes the original data according to the query request, and takes the processing result as the processing result. The region server summarizes the query results obtained from each KV storage device, and provides the final result to the client as a response to the service request.

可选地，区域服务器向KV存储设备发送查询请求前，还查询KV存储设备运行的应用程序，以获知KV存储设备能否处理查询请求。若KV存储设备因缺乏应用程序而无法处理查询请求，区域服务器还指示KV存储设备更新并并行更新后的应用程序。区域服务器也查询KV存储设备的计算能力和/或计算负载，根据KV存储设备的计算能力和/或计算负载，将查询请求发送给恰当的KV存储设备。Optionally, before sending the query request to the KV storage device, the region server also queries the application program running on the KV storage device to know whether the KV storage device can handle the query request. If the KV storage device is unable to process the query request due to lack of application programs, the region server also instructs the KV storage device to update the updated application programs in parallel. The region server also queries the computing capability and/or computing load of the KV storage device, and sends the query request to an appropriate KV storage device according to the computing capability and/or computing load of the KV storage device.

可选地，KV存储设备响应于自身计算能力不足，还请求区域服务器重新生成查询请求，并发送给其他KV存储设备。Optionally, the KV storage device also requests the region server to regenerate the query request and sends it to other KV storage devices in response to its own insufficient computing capability.

可选地，区域服务器具有较大的权限，并可使用存储系统中的全部资源。Optionally, the region server has greater authority and can use all resources in the storage system.

图4A是根据本申请实施例的存储系统实施云计算的流程图。FIG. 4A is a flow chart of implementing cloud computing by a storage system according to an embodiment of the present application.

如图4A所示，客户端向区域服务器发起业务请求，例如，查询车牌为ABC123的车辆在过去24小时在哪里出现。As shown in FIG. 4A , the client initiates a service request to the region server, for example, querying where the vehicle with the license plate ABC123 appeared in the past 24 hours.

客户端知晓为其服务的区域服务器，从而直接向区域服务器发出业务请求。可选地，区域服务器故障，客户端向根服务器发出请求以查询其可用的区域服务器。根服务器维护存储系统中所有可用的区域服务器，并更新所维护的区域服务器的状态，并向客户端指示其应当使用的区域服务器。The client knows the regional server serving it, so it directly sends a service request to the regional server. Optionally, a region server fails, and the client makes a request to the root server to query its available region servers. The root server maintains all available area servers in the storage system, updates the status of the maintained area servers, and indicates to the client which area server it should use.

区域服务器根据接收的业务请求，向同业务请求对应的资源发出查询请求。例如，区域服务器识别客户端查询具有指定车牌的车辆，而向同摄像头耦合的KV存储设备发出查询请求。区域服务器根据业务请求利用指定的计算过程生成用于访问KV存储设备的键(K)。例如，区域服务器将服务请求提供给AI单元，并根据AI单元的一个或多个节点的值生成键(K)。According to the service request received, the regional server sends a query request to the resource corresponding to the service request. For example, the area server recognizes that the client inquires about a vehicle with a specified license plate, and sends an inquiry request to the KV storage device coupled with the camera. The region server generates a key (K) for accessing the KV storage device through a specified calculation process according to the service request. For example, the region server provides the service request to the AI unit, and generates a key (K) according to the value of one or more nodes of the AI unit.

响应于接收到区域服务器提供的键(K)，KV存储设备C将同键(K)对应的值(V)提供给区域服务器。当KV存储设备中记录了同查询请求对应的内容，值(V)是例如出现了车牌为ABC123的车辆的视频的快照、原始视频的存储位置、快照被记录的时间等结构化信息。区域服务器将值(V)提供给客户端作为对业务请求的处理结果。In response to receiving the key (K) provided by the region server, the KV storage device C provides the value (V) corresponding to the key (K) to the region server. When the content corresponding to the query request is recorded in the KV storage device, the value (V) is structural information such as a snapshot of the video of the vehicle whose license plate is ABC123, the storage location of the original video, and the time when the snapshot was recorded. The region server provides the value (V) to the client as a result of processing the service request.

作为又一个例子，区域服务器将查询请求发送给KV存储设备上运行的应用程序。查询请求指示了要使用的应用程序。应用程序根据查询请求对KV存储设备存储的数据进行处理。例如，应用程序根据查询请求生成键(K)，使用键(K)从KV存储设备得到对应的值(V)，从值(V)获取原始视频数据的存储位置，并从该存储位置获取原始视频数据，对视频数据进行分析，得到其中出现了所查询的车牌为ABC123的车辆的一幅或多幅视频截图，并附加上原始视频的存储位置、快照被记录的时间等结构化信息提供给区域服务器作为对查询请求的响应。As yet another example, a region server sends query requests to applications running on the KV storage device. The query request indicates which application to use. The application program processes the data stored in the KV storage device according to the query request. For example, the application program generates a key (K) according to the query request, uses the key (K) to obtain the corresponding value (V) from the KV storage device, obtains the storage location of the original video data from the value (V), and obtains the original video data from the storage location Video data, analyze the video data, get one or more video screenshots of the vehicle with the queried license plate ABC123, and add structured information such as the storage location of the original video and the time when the snapshot was recorded to provide to Region servers respond to query requests.

图4B是根据本申请又一实施例的存储系统实施云计算的流程图。在图4B中区域服务器向多个KV存储设备(KV存储设备C与KV存储设备D)发出查询请求(键(K))，并接收多个KV存储设备输出的同键(K)对应的值(V)。区域服务器还对接收的多个值(V)(同查询请求对应的结构化信息)进行整理，例如将多份结构化信息展示在一个页面中、删除重复信息、按相关性/时间先后排序等。区域服务器将整理后的多个值(V)提供给客户端以向用户展示。Fig. 4B is a flowchart of implementing cloud computing by a storage system according to another embodiment of the present application. In Figure 4B, the region server sends a query request (key (K)) to multiple KV storage devices (KV storage device C and KV storage device D), and receives the value corresponding to the same key (K) output by multiple KV storage devices (V). The region server also organizes the received multiple values (V) (structured information corresponding to the query request), such as displaying multiple pieces of structured information on one page, deleting duplicate information, sorting by relevance/time, etc. . The region server provides the collated multiple values (V) to the client for presentation to the user.

图4C是根据本申请另一实施例的存储系统实施云计算的流程图。FIG. 4C is a flowchart of implementing cloud computing by a storage system according to another embodiment of the present application.

如图4C所示，区域服务器响应于客户端的业务请求，将查询请求发送给KV存储设备C的应用程序A。KV存储设备的应用程序A识别出自身存储的值(V)中尚未包含车牌信息，应用程序A生成计算请求，并指示同其耦合的计算设备(例如，运行在KV存储设备中的另一应用程序B，或同KV存储设备耦合的服务器)对同KV存储设备关联的原始视频数据进行分析，得到其中出现了所查询的车牌为ABC123的车辆的一幅或多幅视频截图，提供给KV存储设备(应用程序A)。KV存储设备(应用程序A)将获取的视频截图，附加上原始视频的存储位置、快照被记录的时间等结构化信息提供给区域服务器作为对查询请求的响应。As shown in FIG. 4C , the region server sends a query request to the application program A of the KV storage device C in response to the service request of the client. Application A of the KV storage device recognizes that the value (V) stored by itself does not contain license plate information, and application A generates a calculation request, and instructs the computing device coupled with it (for example, another application running in the KV storage device Program B, or a server coupled with the KV storage device) analyzes the original video data associated with the KV storage device, and obtains one or more video screenshots of the vehicle whose license plate is ABC123 in question, and provides it to the KV storage Device (App A). The KV storage device (application A) provides the captured video screenshots, plus structured information such as the storage location of the original video and the time when the snapshot was recorded, to the regional server as a response to the query request.

可选地，在等待计算设备处理计算请求期间，KV存储设备还告知区域服务器等待一段时间，KV存储设备需要一些时间来处理区域服务器的查询请求。Optionally, during waiting for the computing device to process the computing request, the KV storage device also informs the region server to wait for a period of time, and the KV storage device needs some time to process the query request of the region server.

如图4D所示，图4D展示的实施例同图4C展示的实施例类似，差别在于，KV存储设备C的应用程序A生成计算请求，指示同其耦合的计算设备D处理计算请求。然而计算设备D因某种原因(例如，繁忙或缺乏进行相应处理的应用程序)拒绝了计算请求。作为响应，KV存储设备C的应用程序A向区域服务器查询可处理该计算请求的资源。区域服务器响应于应用程序A的请求，告知应用程序A可使用计算设备E来处理该计算请求，并向应用程序A提供计算设备E的计算设备标识符等信息。KV存储设备C的应用程序A根据区域服务器的指示，指示计算设备E处理计算请求，并且可选地，还通知区域服务器等待一段时间。计算设备E处理计算请求，将处理结果提供给KV存储设备C的应用程序A。应用程序A将收到的处理结果，附加上同查询请求对应的结构化信息提供给区域服务器作为对查询请求的响应。As shown in FIG. 4D , the embodiment shown in FIG. 4D is similar to the embodiment shown in FIG. 4C , the difference is that the application A of the KV storage device C generates a computing request, and instructs the computing device D coupled to it to process the computing request. However, computing device D rejects the computing request for some reason (for example, being busy or lacking an application to process accordingly). In response, application A of KV storage device C queries the region server for resources that can handle the computation request. In response to application A's request, the region server informs application A that computing device E can be used to process the computing request, and provides application A with information such as the computing device identifier of computing device E. The application program A of the KV storage device C instructs the computing device E to process the computing request according to the instruction of the region server, and optionally, notifies the region server to wait for a period of time. The computing device E processes the computing request, and provides the processing result to the application program A of the KV storage device C. Application A provides the received processing result, plus structured information corresponding to the query request, to the region server as a response to the query request.

可选地，计算设备D响应于收到来自应用程序A的计算请求。根据计算请求，计算设备D知晓其有能力处理该计算请求，但需要安装指定的应用程序A’。计算设备D向区域服务器请求安装应用程序A’，并通知应用程序A等待一段时间。响应于计算设备D的请求，区域服务器将应用程序A’发送给计算设备D。计算设备D运行所接收的应用程序A’来处理计算请求，并将计算请求的处理结果提供给应用程序A。Optionally, computing device D is responsive to receiving a computing request from application A. According to the calculation request, the computing device D knows that it is capable of handling the calculation request, but it needs to install the specified application program A'. The computing device D requests the installation of the application program A' from the regional server, and notifies the application program A to wait for a period of time. In response to computing device D's request, the region server sends application A' to computing device D. The computing device D runs the received application program A' to process the computing request, and provides the processing result of the computing request to the application program A.

图4E是根据本申请依然又一实施例的存储系统实施云计算的流程图。Fig. 4E is a flow chart of implementing cloud computing by a storage system according to yet another embodiment of the present application.

如图4E所示，KV存储设备C被写入了新的数据，例如，同摄像头新捕获的一段视频对应的键(K)与视频的结构化数据(值(V))。然而结构化数据中没有车牌信息。KV存储设备C的应用程序A希望在结构化数据中添加车牌信息，而将计算请求发送给同KV存储设备C关联的计算设备D，计算请求中指示了原始视频的存储位置以及从原始视频中提取车牌信息。计算设备D响应于收到计算请求，对原始视频数据进行分析，得到其中出现的车牌信息，以及可选地出现了车牌信息的视频画面的截图，将车牌信息、截图和/或截图出现的时间提供给应用程序A。As shown in FIG. 4E , new data is written into the KV storage device C, for example, the key (K) corresponding to a video newly captured by the camera and the structured data (value (V)) of the video. However, there is no license plate information in the structured data. Application A of KV storage device C wants to add license plate information to structured data, and sends a calculation request to computing device D associated with KV storage device C. The calculation request indicates the storage location of the original video and the information from the original video. Extract license plate information. Computing device D analyzes the original video data in response to receiving the calculation request, obtains the license plate information appearing therein, and optionally a screenshot of the video screen in which the license plate information appears, and stores the license plate information, the screenshot and/or the time when the screenshot appears Provided to application A.

可选地，计算设备D为处理计算请求，还请求区域服务器提供应用程序A’，并运行应用程序A’来从原始视频数据中提取车牌信息。Optionally, in order to process the computing request, the computing device D also requests the regional server to provide the application program A', and runs the application program A' to extract the license plate information from the original video data.

图4F是根据本申请依然另一实施例的存储系统实施云计算的流程图。Fig. 4F is a flow chart of implementing cloud computing by a storage system according to still another embodiment of the present application.

一些情况下，具有特定功能的应用程序B被更新为应用程序B’，区域服务器将更新后的应用程序B’安装到同其耦合的计算设备。为运行应用程序B’，需要计算设备满足指定的条件(例如，具有AI加速器或压缩/解压缩加速器)。区域服务器向同其耦合的一个或多个计算设备(例如，计算设备A与计算设备B)广播查询请求，以获取各计算设备是否满足运行应用程序B’的条件。可选地，查询请求还询问各计算设备是否已安装了应用程序B’和/或已安装的应用程序B’的版本。如图4F所示，根据各计算设备对查询请求的应答，区域服务器知晓计算设备A能够安装应用程序B’，而计算设备B不能安装应用程序B’。从而区域服务器将应用程序B’发送给计算设备A并指示其安装应用程序B’，并且区域服务器通知计算设备B其将不安装应用程序B’。计算设备A还就应用程序B’安装完成向区域服务器提供确认指示，而计算设备B就不安装应用程序B’向区域服务器提供确认指示。In some cases, the application B with a specific function is updated to the application B', and the regional server installs the updated application B' to the computing device coupled thereto. In order to run application B', the computing device needs to meet specified conditions (for example, having an AI accelerator or a compression/decompression accelerator).

The latest or specified version and install it.

实施例四Embodiment Four

雾计算的客户端维护自己的资源数据库，以知晓存储系统中有哪些资源可用于响应请求。可选地，雾计算客户端也使用存储系统提供的开放资源，并在自己的资源数据库中维护可用的开放资源。作为举例，商厦内的摄像头是私有资源，仅允许商厦的雾计算客户端访问，根据摄像头获取的视频数据而存储在KV存储设备中的结构化数据允许存储系统的所有用户/设备访问，而响应雾计算客户端发起的业务请求得到的计算结果(结论数据)是仅允许雾计算客户端访问。The client of fog computing maintains its own resource database to know which resources are available in the storage system to respond to requests. Optionally, the fog computing client also uses the open resources provided by the storage system, and maintains available open resources in its own resource database. As an example, the camera in the commercial building is a private resource that is only allowed to be accessed by the fog computing client of the commercial building. The structured data stored in the KV storage device according to the video data acquired by the camera is allowed to be accessed by all users/devices of the storage system, while the response The calculation result (conclusion data) obtained by the business request initiated by the fog computing client is only allowed to be accessed by the fog computing client.

作为又一个例子，KV存储设备在响应雾计算客户端发起的业务请求时，可使用其自己的存储与计算能力响应请求，也可使用与自身临近的私有资源(例如，在商厦内的KV存储设备与计算设备)。作为有一个例子，根据从KV存储设备访问私有资源所经的网络跳数评价KV存储设备与私有资源的距离。As another example, when a KV storage device responds to a business request initiated by a fog computing client, it can use its own storage and computing capabilities to respond to the request, or use private resources close to itself (for example, the KV storage device in a commercial building) devices and computing devices). As an example, the distance between the KV storage device and the private resource is evaluated according to the number of network hops through which the private resource is accessed from the KV storage device.

图5A是根据本申请实施例的存储系统实施雾计算的流程图。Fig. 5A is a flow chart of implementing fog computing by a storage system according to an embodiment of the present application.

如图5A所示，雾计算客户端向KV存储系统发起业务请求，例如，查询摄像头C在过去24小时拍摄到的消费者人数。雾计算客户端从自身的数据库获取KV存储设备C关联于摄像头C，从而向KV存储设备C发出业务请求。As shown in Figure 5A, the fog computing client initiates a service request to the KV storage system, for example, querying the number of consumers captured by camera C in the past 24 hours. The fog computing client obtains the KV storage device C associated with the camera C from its own database, and sends a service request to the KV storage device C.

KV存储设备C根据接收的业务请求，通过自身的KV存储的值(V)的结构化信息获取摄像头C在过去24小时拍摄的原始视频数据的存储位置，加载原始视频数据并分析，识别原始视频数据中出现的人物并统计，作为对雾计算客户端的业务请求的响应。作为举例，KV存储设备C运行的应用程序A用于从视频中识别人物。在又一个例子中，KV存储设备C无法运行应用程序A，KV存储设备访问与其临近的一个或多个计算设备D，并指示计算设备D从原始视频数据中识别人物。计算设备D将识别结果提供给KV存储设备C。According to the service request received, KV storage device C obtains the storage location of the original video data captured by camera C in the past 24 hours through the structured information of its own KV storage value (V), loads the original video data, analyzes and identifies the original video The characters appearing in the data are counted as a response to the business request of the fog computing client. As an example, the application program A run by the KV storage device C is used to identify people from the video. In yet another example, the KV storage device C cannot run the application program A, and the KV storage device accesses one or more computing devices D adjacent to it, and instructs the computing device D to recognize characters from the original video data. The computing device D provides the recognition result to the KV storage device C.

在另一个例子中，KV存储设备C尚未被安装用于从视频中识别人物的应用程序。KV存储设备C向应用分发服务器请求用于从视频中识别人物的应用程序，或请求指定的应用程序A。应用分发服务器响应于请求将应用程序A发送给KV存储设备，并在KV存储设备上安装并运行应用程序A。KV存储设备C运行应用程序A来从原始视频数据中识别人物。在依然又一个例子中，KV存储设备所请求的计算设备D，通过应用分发服务器安装应用程序A。In another example, the KV storage device C has not been installed with an application for identifying people from videos. The KV storage device C requests an application program for identifying a person from a video, or requests a specified application program A from the application distribution server. The application distribution server sends the application program A to the KV storage device in response to the request, and installs and runs the application program A on the KV storage device. KV storage device C runs application program A to recognize people from raw video data. In yet another example, the computing device D requested by the KV storage device installs the application program A through the application distribution server.

作为举例，应用分发服务器是区域服务器(也参看图3)。或者，在临近于雾计算客户端的网络中部署应用分发服务器，用于为临近于雾计算客户端的网络中的各资源分发应用程序。应用分发服务器也作为数据库，提供资源查询服务。雾计算客户端从应用分发服务器获取可用的资源，以及资源的位置、属性、安装的应用程序等信息。By way of example, the application distribution server is a regional server (see also Figure 3). Alternatively, an application distribution server is deployed in a network close to the fog computing client, for distributing application programs to resources in the network close to the fog computing client. The application distribution server also serves as a database to provide resource query services. The fog computing client obtains available resources from the application distribution server, as well as information such as resource locations, attributes, and installed applications.

图5B是根据本申请又一实施例的存储系统实施雾计算的流程图。Fig. 5B is a flow chart of implementing fog computing by a storage system according to another embodiment of the present application.

如图5B所示，雾计算客户端向KV存储设备发起业务请求，例如，查询摄像头C在过去24小时拍摄到的消费者人数。雾计算客户端向其能访问到的任何KV存储设备发起业务请求(例如通过广播)。As shown in Figure 5B, the fog computing client initiates a service request to the KV storage device, for example, querying the number of consumers captured by camera C in the past 24 hours. The fog computing client initiates a service request (for example, by broadcasting) to any KV storage device it can access.

接收到业务请求的KV存储设备，例如KV存储设备C，访问计算设备查询服务器，以获得能够处理该业务请求的一个或多个计算设备。计算设备查询服务器是例如KV存储设备中的应用程序、网络中临近于该KV存储设备C部署的计算设备、或应用分发服务器(也参看图5A)。The KV storage device that receives the service request, such as the KV storage device C, accesses the computing device to query the server, so as to obtain one or more computing devices capable of processing the service request. The computing device query server is, for example, an application program in the KV storage device, a computing device deployed close to the KV storage device C in the network, or an application distribution server (see also FIG. 5A ).

计算设备查询服务器在网络中广播请求，询问与其临近的网络中的哪些计算设备能响应该业务请求或从该业务请求产生的查询请求。请求被广播的范围限于同计算设备查询服务器临近的计算设备，从而避免请求广播请求在网络中洪泛。The computing device query server broadcasts a request in the network to ask which computing devices in its adjacent network can respond to the service request or query requests generated from the service request. The range in which the request is broadcast is limited to computing devices that are close to the computing device query server, thereby avoiding flooding of the request broadcast request in the network.

继续参看图5B，计算设备1与计算设备2响应于广播请求向计算设备查询服务器给出应答，指示其可以处理业务请求或查询请求。计算设备查询服务器将计算设备1与计算设备2作为可用的计算设备资源提供给KV存储设备C。KV存储设备C选择可用的计算设备之一(例如，计算设备2)，并向选择的计算设备发出业务请求或查询请求，以及从选择的计算设备接收处理结果，并将处理结果提供给雾计算客户端。Continuing to refer to FIG. 5B , computing device 1 and computing device 2 give a response to the computing device query server in response to the broadcast request, indicating that it can process the service request or query request. The computing device query server provides computing device 1 and computing device 2 as available computing device resources to the KV storage device C. The KV storage device C selects one of the available computing devices (for example, computing device 2), and sends a service request or query request to the selected computing device, and receives the processing result from the selected computing device, and provides the processing result to the fog computing client.

图5C是根据本申请依然又一实施例的存储系统实施雾计算的流程图。Fig. 5C is a flow chart of implementing fog computing by a storage system according to yet another embodiment of the present application.

图5C展示的实施例同图5B的实施例相似。区别在于省略了计算设备查询服务器。The embodiment shown in FIG. 5C is similar to the embodiment in FIG. 5B. The difference is that the computing device query server is omitted.

如图5C所示，KV存储设备C的应用程序响应于雾计算客户端的业务请求，在网络中广播请求，询问与其临近的网络中的哪些计算设备能响应该业务请求或从该业务请求产生的查询请求。作为举例，KV存储设备C在距其1跳的网络范围内广播请求。参看图5C，计算设备3-1与计算设备3-2是同KV存储设备C距离在1跳网络距离内的计算设备，并接收到KV存储设备C的广播请求。As shown in Figure 5C, the application program of the KV storage device C responds to the service request of the fog computing client, broadcasts the request in the network, and asks which computing devices in the adjacent network can respond to the service request or generate from the service request query request. As an example, the KV storage device C broadcasts a request within the network range of 1 hop away from it. Referring to FIG. 5C, the computing device 3-1 and the computing device 3-2 are computing devices within 1 hop network distance from the KV storage device C, and have received the KV storage device C's broadcast request.

响应于广播请求，计算设备3-1与计算设备3-2都向KV存储设备C给出应答，各自向KV存储设备C指示其可以处理查询请求。计算设备3-1与计算设备3-2还以各自为起点，距离1跳网络距离内转发广播请求。计算设备4-1与计算设备4-2相距计算设备3-1或计算设备3-2的网络距离小于1跳，并接收到所转发的网络请求。响应于广播请求，计算设备4-1与计算设备4-2都向KV存储设备C给出应答，各自向KV存储设备C指示其可以处理查询请求。作为举例，广播请求被传播的范围，被限制为从KV存储设备C开始的2跳网络距离，从而计算设备4-1与计算设备4-2不再对广播请求进行转发。In response to the broadcast request, both the computing device 3-1 and the computing device 3-2 give responses to the KV storage device C, each indicating to the KV storage device C that it can process the query request. The computing device 3-1 and the computing device 3-2 also use each as a starting point, and forward the broadcast request within a 1-hop network distance. The network distance between the computing device 4-1 and the computing device 4-2 is less than 1 hop from the computing device 3-1 or computing device 3-2, and the forwarded network request is received. In response to the broadcast request, both the computing device 4-1 and the computing device 4-2 give responses to the KV storage device C, each indicating to the KV storage device C that it can process the query request. As an example, the propagation range of the broadcast request is limited to the 2-hop network distance from the KV storage device C, so that the computing device 4-1 and the computing device 4-2 no longer forward the broadcast request.

KV存储设备C响应于收到计算设备的应答，选择由计算设备3-1处理查询请求，并就选择结果告知计算设备3-1。可选地，KV存储设备C还将拒绝使用计算设备3-2、计算设备4-1与计算设备4-2的选择结果分别告知计算设备3-2、计算设备4-1与计算设备4-2。In response to receiving the response from the computing device, the KV storage device C selects the computing device 3-1 to process the query request, and notifies the computing device 3-1 of the selection result. Optionally, the KV storage device C will also inform the computing device 3-2, computing device 4-1 and computing device 4- 2.

KV存储设备C向选择的计算设备3-1发出查询请求，以及从选择的计算设备3-1接收处理结果，并将处理结果提供给雾计算客户端。The KV storage device C sends a query request to the selected computing device 3-1, receives the processing result from the selected computing device 3-1, and provides the processing result to the fog computing client.

返回参看图3，根据本申请实施例的客户端，既可以通过区域服务器发起根据图4A-图4F所示的云计算流程的业务查询，也可以通过与其临近或绑定的KV存储设备发起根据图5A-图5C所示的雾计算流程的业务查询。从而融合了云计算与雾计算。对网络中的各个参与者都能提供更有利的服务。Referring back to Fig. 3, the client according to the embodiment of the present application can either initiate a service query according to the cloud computing process shown in Fig. 4A-Fig. The business query of the fog computing process shown in Fig. 5A-Fig. 5C. Thus integrating cloud computing and fog computing. All participants in the network can provide more favorable services.

根据本申请实施例的存储系统可由多种机构部署，降低了部署成本。例如，由公共服务用户，例如环境保护主管部门或公共安全主管部门部署根据本申请的存储系统(包括根服务器、区域服务器、一种或多种资源与客户端)S，并通过区域服务器使用存储系统的全部资源。而对于新建立的商场，商场网络(商场私有)中部署了多种资源(包括摄像头、KV存储设备、计算设备、客户端等)，商场网络可被加入到存储系统S。通过在区域服务器中维护新加入的商场网络中的各项资源，原为存储系统S而部署的客户端得以使用商场网络的资源，从而降低了更新存储系统S所需的成本，并且商场网络的资源一旦接入存储系统S，即可被存储系统S的客户端通过云计算方式所使用。从而存储系统S的IT基础设施的部分由私有网络加以补充，降低了存储系统S的建设成本，也解决了作为公有云的存储系统S与私有网络难以互联的缺陷。而属于商场网络的客户端/用户通过雾计算方式除了使用商场网络内部署的资源，还可使用存储系统S中被公开的部分资源。The storage system according to the embodiment of the present application can be deployed by various institutions, which reduces the deployment cost. For example, a public service user, such as an environmental protection authority or a public safety authority, deploys a storage system (including a root server, an area server, one or more resources, and a client) S according to the present application, and uses the storage system S through an area server. all resources of the system. For a newly established shopping mall, multiple resources (including cameras, KV storage devices, computing devices, clients, etc.) are deployed in the shopping mall network (privately owned by the shopping mall), and the shopping mall network can be added to the storage system S. By maintaining various resources in the newly added shopping mall network in the regional server, the client originally deployed for the storage system S can use the resources of the shopping mall network, thereby reducing the cost of updating the storage system S, and the shopping mall network Once the resource is connected to the storage system S, it can be used by the client of the storage system S through cloud computing. Therefore, part of the IT infrastructure of the storage system S is supplemented by the private network, which reduces the construction cost of the storage system S, and also solves the defect that the storage system S as a public cloud is difficult to interconnect with the private network. Clients/users belonging to the shopping mall network can also use some resources disclosed in the storage system S in addition to the resources deployed in the shopping mall network through fog computing.

并且，存储系统S的资源(KV存储设备、计算设备、数据采集设备等)得到了被更多利用的机会，除了被存储系统S的客户端使用，还可被私有网络(商场网络)的客户端使用。In addition, the resources of the storage system S (KV storage devices, computing devices, data acquisition devices, etc.) have more chances to be used. In addition to being used by the clients of the storage system S, they can also be used by the clients of the private network (the shopping mall network) terminal use.

对于用户/客户端，从存储系统S中能够获取更多种与更多量的资源，除了在存储系统被公共维护的资源，还有机会使用随后加入到存储系统S的私有网络的资源，更多的资源使用户/客户端的需求被更多且更高效的满足。For users/clients, more types and more resources can be obtained from the storage system S. In addition to the resources that are publicly maintained in the storage system, there is also the opportunity to use the resources that are subsequently added to the private network of the storage system S, and more More resources enable users/clients' needs to be met more and more efficiently.

进一步地，雾计算方式产生的网络流量被限制在同发起业务请求的客户端临近的范围内，减少了数据在网络中传输的距离，降低了网络负载与功耗。Furthermore, the network traffic generated by the fog computing method is limited to the range close to the client that initiates the service request, which reduces the distance of data transmission in the network and reduces network load and power consumption.
