The server includes, but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.

参照图1所示，为本发明一实施例提供的基于FC交换网终端连接状态的动态更新方法的流程示意图。在本实施例中，所述基于FC交换网终端连接状态的动态更新方法包括：Referring to FIG. 1 , it is a schematic flowchart of a method for dynamically updating terminal connection status based on FC switching network provided by an embodiment of the present invention. In this embodiment, the dynamic update method based on the connection state of the FC switching network terminal includes:

S1、接收终端的登入请求，将所述登入请求发送至预构建的交换机，利用所述交换机为所述终端分配终端地址。S1. Receive a login request from a terminal, send the login request to a pre-built switch, and use the switch to assign a terminal address to the terminal.

可解释的，所述登入请求(Login，简称LOGI)指所述终端接入FC(Fiber Channel，光纤通道)交换网络时使用的通信协议。所述FC交换网络利用FC协议来构建，FC协议是一种高速串行通信协议，具有高带宽、高可靠性、低延迟、灵活的拓扑结构以及开放性的特点，主要应用于航空电子通信系统。在不同的FC协议中，终端之间的交互模式也有所不同，例如：在FC-AE-1553中，终端分为网络控制器(NC)和网络终端(NT)，两者交互模式为命令响应式；在FC-AE-ASM中，各终端是同等关系。It can be explained that the login request (Login, LOGI for short) refers to a communication protocol used when the terminal accesses an FC (Fiber Channel, Fiber Channel) switching network. The FC switching network is constructed using the FC protocol. The FC protocol is a high-speed serial communication protocol with the characteristics of high bandwidth, high reliability, low delay, flexible topology and openness, and is mainly used in avionics communication systems . In different FC protocols, the interaction modes between terminals are also different. For example: in FC-AE-1553, terminals are divided into network controller (NC) and network terminal (NT), and the interaction mode between the two is command response formula; in FC-AE-ASM, each terminal is an equal relationship.

需解释的，由于不同的FC协议仅仅在FC-4层(upper layer protocol映射曾，简称ULP映射层)有差异，因此可提出一独立于FC-4的FC交换网络故障监测和终端连接信息动态维护更新方式，对于所有的FC协议均适用。It should be explained that because different FC protocols differ only in the FC-4 layer (upper layer protocol mapping layer, referred to as ULP mapping layer), it is possible to propose a FC switching network fault monitoring and terminal connection information dynamics independent of FC-4 The maintenance update method is applicable to all FC protocols.

进一步地，所述FC交换网络具有多种拓扑结构，其中常见的是交换型网络，如图1所示，FC交换网络内有若干个交换机互联，每个交换机可以连接若干个终端，各终端之间的通信数据通过交换机进行转发。Further, the FC switching network has a variety of topological structures, among which the switching network is common, as shown in Figure 1, there are several switches interconnected in the FC switching network, and each switch can be connected to several terminals. The communication data between them is forwarded through the switch.

本发明实施例中，所述将所述登入请求发送至预构建的交换机，利用所述交换机为所述终端分配终端地址，包括：In the embodiment of the present invention, the sending the login request to a pre-built switch, and using the switch to assign a terminal address to the terminal includes:

根据所述登入请求，获取所述终端的登入协议；Obtain a login protocol of the terminal according to the login request;

根据所述终端的登入协议，在所述交换机内，生成所述终端的终端地址；generating a terminal address of the terminal in the switch according to the login protocol of the terminal;

将所述终端地址填充至预构建的初始登入响应帧中，得到目标登入响应帧；Filling the terminal address into the pre-built initial login response frame to obtain the target login response frame;

将所述目标登入响应帧回传至所述终端，完成所述终端地址的分配。Returning the target login response frame to the terminal to complete the allocation of the terminal address.

可理解的，所述登入协议(Fabric Login，简称FLOGI)指终端与交换机之间建立连接的登录协议。Understandably, the login protocol (Fabric Login, FLOGI for short) refers to a login protocol for establishing a connection between a terminal and a switch.

应明白的，所述交换机接收到登入协议后，将会为终端分配地址，并填充在所述初始登入响应帧中，得到所述目标登入响应帧。所述目标登入响应帧(简称FLOGI LS_ACC)指交换机接收终端发出的登入协议时回复的LS_ACC帧。所述初始登入响应帧指未填充所述终端地址的待填充响应帧。It should be understood that after receiving the login protocol, the switch will assign an address to the terminal and fill it in the initial login response frame to obtain the target login response frame. The target login response frame (FLOGI LS_ACC for short) refers to the LS_ACC frame returned by the switch when receiving the login protocol sent by the terminal. The initial login response frame refers to a to-be-filled response frame that is not filled with the terminal address.

可解释的，所述终端登入FC交换网络属于显性登录，登入和登出所涉及的帧均为ELS类型帧，各字段定义可参见FC-LS-2中4.2.7Login(FLOGI/PLOGI)和4.2.8Logout(LOGO)。It can be explained that the terminal's login to the FC switching network is an explicit login, and the frames involved in the login and logout are all ELS type frames. For the definition of each field, please refer to 4.2.7 Login (FLOGI/PLOGI) and 4.2 in FC-LS-2. .8 Logout(LOGO).

S2、获取所述终端的名称及所述交换机的标识，根据所述终端地址、终端的名称及所述交换机的标识，构建终端信息。S2. Obtain the name of the terminal and the identifier of the switch, and construct terminal information according to the address of the terminal, the name of the terminal, and the identifier of the switch.

可解释的，所述终端信息包括终端的名称、终端地址及所述终端连接交换机的标识等，可以根据实际需求增加其他信息。It can be explained that the terminal information includes the name of the terminal, the address of the terminal, and the identifier of the switch to which the terminal is connected, and other information can be added according to actual needs.

S3、将所述终端信息存储于所述交换机的终端登入信息表中，得到本地登入更新终端信息表。S3. Store the terminal information in a terminal login information table of the switch to obtain a local login update terminal information table.

需解释的，所述终端登入信息表指接入FC交换网络并且可以正常通信的终端信息的集合。所述本地登入更新终端信息表指将所述终端信息存储于所述交换机的终端登入信息表中，实现对所述交换机中原有的终端登入信息表进行更新，进而得到的信息表。It should be explained that the terminal login information table refers to a collection of terminal information that accesses the FC switching network and can communicate normally. The local login update terminal information table refers to an information table obtained by storing the terminal information in the terminal login information table of the switch to update the original terminal login information table in the switch.

进一步地，可以利用所述交换机负责监测终端与交换机之间物理链路的连接状态，此过程可以通过FC-2层链路故障监测功能实现，若物理层完成字同步，并且链路层完成原语同步，则表示物理链路连接正常，否则表示物理链路为断开状态，当物理链路出现断开状态时，需要删除终端登入信息表中对应的终端信息，若物理链路由断开转为连接时，则不进行任何操作，等待终端重新发起显式登录。Further, the switch can be used to be responsible for monitoring the connection status of the physical link between the terminal and the switch. This process can be realized through the FC-2 layer link fault monitoring function. If the physical layer completes the word synchronization, and the link layer completes the original If the physical link is synchronized, it means that the physical link is connected normally, otherwise it means that the physical link is disconnected. When the physical link is disconnected, the corresponding terminal information in the terminal login information table needs to be deleted. If the physical link is disconnected by When turning to connection, do not perform any operation, and wait for the terminal to re-initiate explicit login.

S4、判断所述交换机是否为预设的主交换机。S4. Determine whether the switch is a preset master switch.

应明白的，所述交换机可分为主交换机和副交换机两种，主交换机负责维护整网的终端接入状态，副交换机负责维护自身连接的终端的接入状态。It should be understood that the switches can be divided into two types: a main switch and a secondary switch. The primary switch is responsible for maintaining the terminal access status of the entire network, and the secondary switch is responsible for maintaining the access status of terminals connected to itself.

详细地，参阅图4所示，所述判断所述交换机是否为预设的主交换机，包括：In detail, referring to FIG. 4, the judging whether the switch is a preset master switch includes:

S41、根据预设的交换机标识集，对交换机进行分类，得到交换机标识-类别对应表；S41. Classify the switches according to the preset switch identification set, and obtain a switch identification-category correspondence table;

S42、利用所述交换机的标识，在所述交换机标识-类别对应表中，查询所述交换机对应的交换机类别；S42. Using the identifier of the switch, query the switch category corresponding to the switch in the switch identifier-category correspondence table;

S43、根据所述交换机类别，判断所述交换机是否为所述主交换机。S43. Determine whether the switch is the master switch according to the type of the switch.

可解释的，所述FC交换网络中的主交换机可以为一个，其它交换机均为副交换机。由于所述交换机的标识为交换机的唯一标识，所以可以利用所述交换机的标识来分辨交换机是主交换机还是副交换机。It can be explained that there may be one main switch in the FC switching network, and the other switches are all secondary switches. Since the identifier of the switch is a unique identifier of the switch, the identifier of the switch can be used to distinguish whether the switch is a master switch or a secondary switch.

若所述交换机是主交换机，则执行S5、不转发所述本地登入更新终端信息表中的终端信息。If the switch is the master switch, perform S5, not forwarding the terminal information in the local login update terminal information table.

可理解的，当所述交换机是主交换机时，表示所述交换机中更新的本地登入更新终端信息表，可以记录整网所有终端的终端信息，此时将所述终端信息存储于所述主交换机中的终端登入信息表，即已实现对整网的终端接入状态的维护。It can be understood that when the switch is the main switch, it means that the updated local login update terminal information table in the switch can record the terminal information of all terminals in the entire network, and at this time, the terminal information is stored in the main switch The terminal login information table in , that is, the maintenance of the terminal access status of the entire network has been realized.

进一步地，所述主交换机既需要维护自身所连接的终端的终端信息，还需要维护整网的终端的终端信息。Further, the main switch needs to maintain not only the terminal information of the terminals connected to itself, but also the terminal information of the terminals in the entire network.

若所述交换机不是主交换机，则执行S6、将所述本地登入更新终端信息表中的终端信息发送至所述主交换机的终端登入信息表中，得到整网登入更新终端信息表。If the switch is not the master switch, execute S6, and send the terminal information in the local login update terminal information table to the terminal login information table of the master switch to obtain the entire network login update terminal information table.

可解释的，所述整网登入更新终端信息表指实时记录所述FC交换网中所有终端的终端信息的信息表。It can be explained that the whole network login update terminal information table refers to an information table that records terminal information of all terminals in the FC switching network in real time.

本发明实施例中，所述将所述本地登入更新终端信息表中的终端信息发送至所述主交换机的终端登入信息表中，得到整网登入更新终端信息表，包括：In the embodiment of the present invention, the terminal information in the local login update terminal information table is sent to the terminal login information table of the main switch to obtain the entire network login update terminal information table, including:

根据预构建的FC通用帧结构及FC网络标准，构建初始通用帧；According to the pre-built FC general frame structure and FC network standard, construct the initial general frame;

改变所述初始通用帧的帧类型，得到初始登入同步帧；changing the frame type of the initial universal frame to obtain an initial login synchronization frame;

将所述终端信息填充至所述初始登入同步帧中，得到目标登入同步帧；Filling the terminal information into the initial login synchronization frame to obtain a target login synchronization frame;

将所述目标登入同步帧，发送至所述主交换机的终端登入信息表中，得到所述整网登入更新终端信息表。The target login synchronization frame is sent to the terminal login information table of the master switch to obtain the entire network login updated terminal information table.

详细地，所述FC通用帧结构可以参阅图2所示。所述初始通用帧指可以通过设置帧类型，来生成可以实现不同功能的通用帧。例如：当所述帧类型(LS_Command Code)的字节为0xA7时，表示网络节点连接状态请求协议(Link State Request，简称LS_REQ)；当所述帧类型(LS_Command Code)的字节为0xA8时，表示网络节点连接状态应答协议(Link StateAcknowledge，简称LS_ACK)。In detail, the general frame structure of the FC can be referred to as shown in FIG. 2 . The initial general frame means that a general frame that can realize different functions can be generated by setting the frame type. For example: when the byte of the frame type (LS_Command Code) is 0xA7, it means the network node link state request protocol (Link State Request, LS_REQ for short); when the byte of the frame type (LS_Command Code) is 0xA8, Represents a link state acknowledgment protocol (Link State Acknowledge, LS_ACK for short) of a network node.

进一步地，所述初始登入同步帧指已设置好帧类型，但还未填充所述终端信息的待完善帧。所述目标登入同步帧(Link State Update，简称LSU)指用于交换机之间进行链路状态同步的数据帧。Further, the initial login synchronization frame refers to a frame to be completed for which the frame type has been set but the terminal information has not been filled. The target login synchronization frame (Link State Update, LSU for short) refers to a data frame used for link state synchronization between switches.

本发明实施例中，所述将所述目标登入同步帧，发送至所述主交换机的终端登入信息表中，得到所述整网登入更新终端信息表，包括：In the embodiment of the present invention, the said target login synchronization frame is sent to the terminal login information table of the master switch to obtain the entire network login update terminal information table, including:

将所述目标登入同步帧，通过所述交换机的级联端口发送至所述主交换机的级联端口；Send the target login synchronization frame to the cascade port of the main switch through the cascade port of the switch;

判断所述主交换机的级联端口，是否首次接收所述目标登入同步帧；Judging whether the cascading port of the main switch receives the target login synchronization frame for the first time;

若所述主交换机的级联端口不是首次接收所述目标登入同步帧，则将所述目标同步帧丢弃；If the cascading port of the master switch is not receiving the target login synchronization frame for the first time, discarding the target synchronization frame;

若所述主交换机的级联端口是首次接收所述目标登入同步帧，则利用所述目标登入同步帧更新所述主交换机的终端登入信息表，得到所述整网登入更新终端信息表。If the cascading port of the main switch receives the target login synchronization frame for the first time, then use the target login synchronization frame to update the terminal login information table of the main switch to obtain the entire network login update terminal information table.

可解释的，通过所述目标登入同步帧将所述终端信息进行封装，再通过所述交互机以及所述FC交换网中其它副交换机的级联端口，将所述目标登入同步帧，发送至所述主交换机的级联端口，从而使得所述主交换机获得所述交换机与对应的终端的终端信息。其中所述FC交换网中其它副交换机的级联端口可能会重复收到所述目标登入同步帧，所以需要将重复的目标登入同步帧丢弃，直至所述主交换机接收到所述目标登入同步帧。主交换机也需要将重复的目标登入同步帧进行丢弃。It can be explained that the terminal information is encapsulated through the target login synchronization frame, and then the target login synchronization frame is sent to The cascading port of the main switch, so that the main switch obtains the terminal information of the switch and the corresponding terminal. The cascading ports of other secondary switches in the FC switching network may repeatedly receive the target login synchronization frame, so the repeated target login synchronization frame needs to be discarded until the main switch receives the target login synchronization frame . The master switch also needs to discard duplicate target login sync frames.

本发明实施例中，所述将所述目标登入同步帧，发送至所述主交换机的终端登入信息表中，得到所述整网登入更新终端信息表之后，所述方法还包括：In the embodiment of the present invention, after sending the target login synchronization frame to the terminal login information table of the main switch, and obtaining the entire network login update terminal information table, the method further includes:

改变所述初始通用帧的帧类型，得到初始链路状态应答帧；changing the frame type of the initial general frame to obtain an initial link state response frame;

将所述终端信息填充至所述初始链路状态应答帧中，得到目标链路状态应答帧；Filling the terminal information into the initial link state response frame to obtain a target link state response frame;

将所述目标链路状态应答帧，通过所述主交换机的级联端口发送至所述交换机的级联端口；Sending the target link state response frame to the cascading port of the switch through the cascading port of the master switch;

判断所述交换机的级联端口，是否首次接收所述目标链路状态应答帧；judging whether the cascading port of the switch receives the target link state response frame for the first time;

若所述交换机的级联端口，不是首次接收所述目标链路状态应答帧，则将所述目标链路状态应答帧丢弃；If the cascading port of the switch does not receive the target link state response frame for the first time, discarding the target link state response frame;

若所述交换机的级联端口，是首次接收所述目标链路状态应答帧，则完成所述目标登入同步帧的发送。If the cascading port of the switch receives the target link state response frame for the first time, the sending of the target login synchronization frame is completed.

可理解的，所述初始链路状态应答帧指已设置好帧类型，但还未封装终端信息的待完善帧。所述目标链路状态应答帧(Link State Update，简称LSA)用于链路状态应答。当所述主交换机接收到所述目标登入同步帧后，开始解析所述目标登入同步帧，并对原有的终端登入信息表进行更新，然后通过接收所述目标登入同步帧的级联端口，将所述目标链路状态应答帧利用所述FC交换网络中的其它副交换机的级联端口，发送至所述交换机。同理，副交换机需要将重复接收到的目标链路状态应答帧丢弃，直至将所述目标链路状态应答帧，发送至所述交换机。It can be understood that the initial link state response frame refers to a frame to be completed for which a frame type has been set but terminal information has not been encapsulated. The target link state response frame (Link State Update, LSA for short) is used for link state response. After the main switch receives the target login synchronization frame, it starts to parse the target login synchronization frame, and updates the original terminal login information table, and then through the cascaded port receiving the target login synchronization frame, and sending the target link state response frame to the switch by using the cascading ports of other sub-switches in the FC switching network. Similarly, the secondary switch needs to discard the repeatedly received target link state response frame until the target link state response frame is sent to the switch.

进一步地，当所述交换机监测到终端与交换机之间物理链路的连接状态出现异常时，不仅需要在所述交换机的终端登入信息表中记录，还需要同步至所述主交换机中。Further, when the switch detects that the connection status of the physical link between the terminal and the switch is abnormal, it not only needs to record in the terminal login information table of the switch, but also needs to be synchronized to the master switch.

S7、接收所述终端的登出请求，将所述登出请求发送至所述交换机，在所述交换机的本地登入更新终端信息表中，删除所述终端信息，得到本地登出更新终端信息表。S7. Receive the logout request of the terminal, send the logout request to the switch, delete the terminal information in the local login update terminal information table of the switch, and obtain the local logout update terminal information table .

可解释的，所述登出请求(Logout，简称LOGO)指终端退出交换机时使用的通信协议。所述本地登出更新终端信息表指根据所述终端的登出操作，更新所述本地登入更新终端信息表，得到的更新信息表。It can be explained that the logout request (Logout, LOGO for short) refers to the communication protocol used when the terminal exits the switch. The local logout update terminal information table refers to an update information table obtained by updating the local login update terminal information table according to a logout operation of the terminal.

详细地，所述接收所述终端的登出请求，将所述登出请求发送至所述交换机之后，所述方法还包括：Specifically, after receiving the logout request of the terminal and sending the logout request to the switch, the method further includes:

改变所述初始通用帧的帧类型，得到初始登出响应帧；changing the frame type of the initial general frame to obtain an initial logout response frame;

将所述终端信息填充至所述初始登出响应帧中，得到目标登出响应帧；Filling the terminal information into the initial logout response frame to obtain a target logout response frame;

将所述目标登出响应帧，发送至所述终端。Sending the target logout response frame to the terminal.

应明白的，所述目标登出响应帧(LOGO LS_ACC)指交换机接受终端登出时回复的LS_ACC帧。It should be understood that the target logout response frame (LOGO LS_ACC) refers to the LS_ACC frame received by the switch when the terminal logs out.

S8、若所述交换机是主交换机，则不转发所述本地登出更新终端信息表中删除的终端信息。S8. If the switch is a master switch, not forwarding the terminal information deleted in the local logout update terminal information table.

可解释的，当所述终端连接的交换机是主交换机时，不需要再将所述终端的登出信息进行同步，就可以实现主交换机维护所述终端的终端信息的目的。It can be explained that when the switch to which the terminal is connected is the main switch, the purpose of maintaining the terminal information of the terminal by the main switch can be achieved without synchronizing the logout information of the terminal.

S9、若所述交换机不是主交换机，则将所述本地登出更新终端信息表中删除的终端信息，在所述主交换机的整网登入更新终端信息表中删除，得到整网登出更新终端信息表。S9. If the switch is not the main switch, delete the terminal information deleted in the local logout update terminal information table from the entire network login update terminal information table of the main switch to obtain the entire network logout update terminal Information Sheet.

需明白的，当所述交换机不是主交换机时，需要将所述本地登出更新终端信息表中删除的终端信息，在所述主交换机的整网登入更新终端信息表中同步删除。此时需要类似所述目标登入同步帧(Link State Update，简称LSU)的同步过程，将所述删除的终端信息，通过构建目标登出同步帧进行封装，再通过与所述目标登入同步帧同样的传送方式，将所述目标登出同步帧发送至主交换机中，再在主交换机中删除对应的终端信息，然后构建并发送链路状态应答帧指所述交换机，实现终端登出信息的同步。It should be understood that when the switch is not the master switch, the terminal information deleted in the local logout update terminal information table needs to be deleted synchronously from the entire network login update terminal information table of the master switch. At this time, a synchronization process similar to the target login synchronization frame (Link State Update, referred to as LSU) is required, and the deleted terminal information is encapsulated by constructing the target login synchronization frame, and then passed the same as the target login synchronization frame. transmission method, send the target logout synchronization frame to the master switch, delete the corresponding terminal information in the master switch, and then build and send a link state response frame to the switch to realize the synchronization of terminal logout information .

相比于背景技术所述：动态网络信息维护方案对于不同的FC协议不具有通用性，无法实现具有多种FC上层协议网络的网络连接信息的更新的现象，本发明实施例在接收到所述终端的登入请求时，利用与所述终端相连的交换机为所述终端分配终端地址，继而根据终端地址、终端的名称及交换机的标识来构建所述终端信息，得到所述终端信息后需要将其存储至所述交换机中的终端登入信息表，从而得到实时的本地登入更新终端信息表，此时需要判断所述交换机是否为主交换机，根据所述交换机的不同权限定位来采取不同的终端信息更新方式，当所述交换机是主交换机时，则不需要多所述终端信息做出任何调整，若所述交换机不是主交换机时，则需要将所述终端信息同步至所述主交换机中的终端登入信息表，得到所述整网登入更新终端信息表，当接收到所述终端的登出请求时，第一步是需要将所述终端的终端信息在所述交换机中删除，再根据所述交换机的具体权限定位，来采用不同的措施，若所述交换机是主交换机，则不再需要进行其他操作，若所述交换机不是主交换机时，则需要将删除的终端信息同步至所述主交换机的整网登入更新终端信息表进行删除，得到所述整网登出更新终端信息表。因此本发明提出的基于FC交换网终端连接状态的动态更新方法、装置、电子设备及计算机可读存储介质，可以解决动态网络信息维护方案对于不同的FC协议不具有通用性，无法实现具有多种FC上层协议网络的网络连接信息的更新的问题。Compared with the description of the background technology: the dynamic network information maintenance scheme is not universal for different FC protocols, and cannot realize the update of network connection information of networks with multiple FC upper layer protocols. The embodiment of the present invention receives the described When a terminal requests a login, the switch connected to the terminal is used to assign a terminal address to the terminal, and then the terminal information is constructed according to the terminal address, the name of the terminal and the identifier of the switch. After obtaining the terminal information, it needs to be Store the terminal login information table in the switch, so as to obtain the real-time local login update terminal information table. At this time, it is necessary to judge whether the switch is the main switch, and take different terminal information updates according to the different authority positions of the switch. In this way, when the switch is the main switch, there is no need to make any adjustments to the terminal information; if the switch is not the main switch, the terminal information needs to be synchronized to the terminal login in the main switch information table, to obtain the terminal information table of the entire network login update terminal, when receiving the logout request of the terminal, the first step is to delete the terminal information of the terminal in the switch, and then according to the switch According to the specific permission location of the specific authority, different measures are adopted. If the switch is the main switch, no other operations are required. If the switch is not the main switch, the deleted terminal information needs to be synchronized to the main switch. The entire network logs in and updates the terminal information table to delete, and the entire network logs out and updates the terminal information table to obtain. Therefore, the dynamic update method, device, electronic equipment and computer-readable storage medium based on the connection status of FC switching network terminals proposed by the present invention can solve the problem that the dynamic network information maintenance scheme is not universal for different FC protocols, and cannot realize multiple The problem of updating the network connection information of the FC upper layer protocol network.
