具体实施方式detailed description
CCN采用以内容(信息)为中心的通信模式来构建网络，解除了内容与位置之间的耦合关系，用户不需要关心从哪台服务器获取内容，而只需关心内容本身，这是一种从“where”到“what”的转变。在通信过程中，所有的网络节点均可以基于内容的名字进行路由和转发，并对传输经过自身的内容进行缓存，以便后续有相同内容请求的用户直接从本地缓存获取内容。CCN adopts a content (information)-centered communication mode to build a network, which removes the coupling relationship between content and location. Users do not need to care about which server to obtain content from, but only care about the content itself. The transition from "where" to "what". During the communication process, all network nodes can perform routing and forwarding based on the name of the content, and cache the content transmitted through itself, so that subsequent users with the same content request can directly obtain the content from the local cache.
在内容中心网络中传输的报文包括两种：兴趣包(Interest packet)和数据包(Data packet)；所述兴趣包及数据包组成如图2示。兴趣包由内容请求用户发出，同时携带被请求的内容名前缀，数据包与兴趣包相对应，携带被请求的内容数据，用于响应内容请求用户发出的兴趣包。The packets transmitted in the content-centric network include two types: an Interest packet (Interest packet) and a data packet (Data packet); the composition of the Interest packet and the data packet is shown in FIG. 2 . The interest packet is sent by the content requesting user and carries the prefix of the requested content name. The data packet corresponds to the interest packet and carries the requested content data, and is used to respond to the interest packet sent by the content requesting user.
每个CCN节点都维护三张用于记录节点内容及指导处理兴趣包和数据包的表，分别为缓存库(CS，Cache Store)、未决请求表(PIT，Pending Interest Table)及转发信息表(FIB，Forwarding Information Base)；其中，CS用于缓存经过该CCN节点的内容数据，以便于在本次通信结束后，缓存下来的数据仍然可以为其它有相同内容请求的用户服务；PIT用于记录经过该节点的兴趣包信息，以便于数据包原路返回；FIB与传输控制协议/因特网互联协议(TCP/IP，Transmission Control Protocol/Internet Protocol)网络中的IP路由表功能类似，用于提供下一跳的转发信息；所述CS、PIT及FIB的格式如图3所示。Each CCN node maintains three tables for recording node content and guiding the processing of interest packets and data packets, which are cache library (CS, Cache Store), pending request table (PIT, Pending Interest Table) and forwarding information table (FIB, Forwarding Information Base); Among them, CS is used to cache the content data passing through the CCN node, so that after the end of this communication, the cached data can still serve other users with the same content request; PIT is used for Record the interest packet information passing through the node so that the original path of the data packet can be returned; The forwarding information of the next hop; the formats of the CS, PIT and FIB are shown in FIG. 3 .
CCN节点处理兴趣包的流程如图4所示，当一个节点收到兴趣包时，首先会匹配CS，如果CS中已经缓存了被请求内容(缓存命中)，则直接沿兴趣包的到达路径转发内容数据并丢弃该兴趣包；如果CS中没有被请求内容(缓存未命中)，则进一步匹配PIT，如果有PIT中有与兴趣包相同的内容名前缀，则在PIT的相应条目中增加兴趣包的到达接口，并丢弃兴趣包；如果PIT也没有匹配，则查找FIB，向所有匹配的端口转发兴趣包(兴趣包的到达接口不再转发)，并在PIT中记录兴趣包的到达接口；如果FIB也没有匹配条目，则丢弃兴趣包或者转发至默认接口。The flow of the CCN node processing the Interest packet is shown in Figure 4. When a node receives the Interest packet, it will first match the CS. If the requested content has been cached in the CS (cache hit), it will be forwarded directly along the arrival path of the Interest packet. Content data and discard the interest packet; if there is no requested content in the CS (cache miss), then further match the PIT, if there is a PIT with the same content name prefix as the interest packet, add the interest packet to the corresponding entry of the PIT If there is no match in the PIT, then search the FIB, forward the interest packet to all matching ports (the arrival interface of the interest packet is no longer forwarded), and record the arrival interface of the interest packet in the PIT; if If there is no matching entry in the FIB, the Interest packet is discarded or forwarded to the default interface.
与兴趣包相比，数据包的处理过程相对简单，如图5所示，当节点收到数据包时，会对数据包的内容名字段进行最长前缀匹配，首先匹配CS，如果有相同的缓存数据，则直接丢弃该数据包；如果没有，继续与PIT中的条目匹配。若匹配PIT，则向相应的端口转发兴趣包，并将数据包缓存至CS，如果PIT中没有匹配的条目，直接丢弃数据包。Compared with interest packets, the processing of data packets is relatively simple. As shown in Figure 5, when a node receives a data packet, it will perform the longest prefix match on the content name field of the data packet, first match CS, if there are the same cache data, discard the data packet directly; if not, continue to match the entry in the PIT. If the PIT is matched, the Interest packet is forwarded to the corresponding port, and the data packet is cached in CS. If there is no matching entry in the PIT, the data packet is discarded directly.
本发明实施例基于图6所示MCDN架构，MCDN部署在基站中，基站之间通过X2接口连接，除原有接口功能外，增加数据转发功能，且基站之间可以通过基于内容的通信模式进行数据通信，给用户提供内容服务；上层采用SDN控制器对下层边缘节点进行管理，并对第三方用户开放接口，提供部分网络管理权限。定义授权用户才被允许使用MCDN服务，软件定义网络(SDN，Software Defined Network)控制器中设置授权信息表来记录用户授权信息。The embodiment of the present invention is based on the MCDN architecture shown in Figure 6. The MCDN is deployed in the base station, and the base stations are connected through the X2 interface. In addition to the original interface function, a data forwarding function is added, and the communication mode between the base stations can be based on the content. Data communication provides users with content services; the upper layer uses SDN controllers to manage the lower layer edge nodes, and opens interfaces to third-party users to provide part of the network management authority. The defined authorized users are allowed to use the MCDN service, and an authorization information table is set in the software defined network (SDN, Software Defined Network) controller to record user authorization information.
在本发明实施例中，MCDN节点接收第一请求包，并检测所述第一请求包是否为预设类型的内容请求包；若所述第一请求包为预设类型的内容请求包，提取所述第一请求包中内容请求关键信息；基于所述内容请求关键信息及预设的用户授权表UAT确定所述第一请求包符合第一授权条件时，获取所述第一请求包对应的优先级信息；基于所述优先级信息及预设的内容中心网络CCN转发策略判断所述第一请求包是否满足CCN转发条件；确定所述第一请求包满足所述CCN转发条件时，基于CCN通信模式对所述第一请求包进行CCN转发处理。In the embodiment of the present invention, the MCDN node receives the first request packet, and detects whether the first request packet is a content request packet of a preset type; if the first request packet is a content request packet of a preset type, extract Content request key information in the first request packet; when determining that the first request packet meets the first authorization condition based on the content request key information and the preset user authorization table UAT, obtain the corresponding Priority information; judging whether the first request packet satisfies the CCN forwarding condition based on the priority information and the preset CCN forwarding strategy; when determining that the first request packet satisfies the CCN forwarding condition, based on the CCN The communication mode performs CCN forwarding processing on the first request packet.
下面结合附图及具体实施例对本发明再作进一步详细的说明。The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
实施例一Embodiment one
图7为本发明实施例路由实现方法流程示意图，如图7所示，本发明实施例路由实现方法包括：FIG. 7 is a schematic flow chart of a routing implementation method according to an embodiment of the present invention. As shown in FIG. 7 , the routing implementation method according to an embodiment of the present invention includes:
步骤701：MCDN节点接收第一请求包，并检测所述第一请求包是否为预设类型的内容请求包。Step 701: The MCDN node receives a first request packet, and detects whether the first request packet is a content request packet of a preset type.
这里，所述MCDN节点位于基站eNodeB，所述预设类型的内容请求包可以为CCN类型的内容请求包。Here, the MCDN node is located at the base station eNodeB, and the content request packet of the preset type may be a content request packet of the CCN type.
在一实施例中，MCDN节点通过检测所述第一请求包的包头结构判断所述第一请求包是否为预设类型的内容请求包，如检测得到所述第一请求包的包头包括内容名部分，可知该第一请求包为CCN类型的内容请求包。In one embodiment, the MCDN node judges whether the first request packet is a content request packet of a preset type by detecting the header structure of the first request packet, for example, the header of the first request packet includes a content name part, it can be seen that the first request packet is a content request packet of the CCN type.
步骤702：确定所述第一请求包为预设类型的内容请求包时，提取所述第一请求包中内容请求关键信息。Step 702: When it is determined that the first request packet is a preset type of content request packet, extract key content request information in the first request packet.
这里，所述内容请求关键信息至少包括用户标识及内容名前缀；Here, the key information of the content request includes at least the user ID and the prefix of the content name;
其中，所述用户标识是一种全局唯一的标识，用于表示用户的唯一性和永久性，可以为用户身份标识(ID，Identification)；Wherein, the user identifier is a globally unique identifier used to represent the uniqueness and permanence of the user, which may be a user identity (ID, Identification);
所述内容名前缀，用于表示某一用户可通过MCDN发起请求的内容，这一内容可以根据不同长度的前缀进行不同粒度的匹配，可以是某一内容提供者的所有内容，也可以是某一内容提供者可提供的某一类内容，也可以是一个空值，这时候说明该用户的所有内容请求均可以通过MCDN服务来满足，第三方业务管理者可以通过SDN控制器的管理界面实现这种可定制的授权功能。The content name prefix is used to indicate the content that a certain user can initiate a request through MCDN. This content can be matched with different granularities according to prefixes of different lengths. It can be all content of a certain content provider, or it can be a certain content. A certain type of content that a content provider can provide can also be a null value, which means that all content requests of the user can be satisfied through the MCDN service, and third-party business managers can realize it through the management interface of the SDN controller This customizable authorization function.
基于本发明所述实施例，在实际应用中，检测得到所述第一请求包并非预设类型的内容请求包时，直接上报所述第一请求包至SDN控制器。Based on the embodiments of the present invention, in practical applications, when it is detected that the first request packet is not a content request packet of a preset type, the first request packet is directly reported to the SDN controller.
步骤703：基于所述内容请求关键信息及预设的UAT确定所述第一请求包符合第一授权条件时，获取所述第一请求包对应的优先级信息。Step 703: Obtain priority information corresponding to the first request packet when it is determined that the first request packet meets the first authorization condition based on the content request key information and the preset UAT.
这里，所述第一请求包对应的优先级信息即发送所述第一请求包的用户对应的优先级信息，优先级A为最高优先级，以此向下逐级降低，考虑当节点负载过重时，可选择优先级高的请求进行服务，第三方管理者也可以通过结合优先级配置实现多样化的定制服务；Here, the priority information corresponding to the first request packet is the priority information corresponding to the user who sent the first request packet. Priority A is the highest priority, which is lowered step by step. Considering that when the node load is too high When it is heavy, the request with high priority can be selected for service, and the third-party manager can also realize diversified customized services by combining priority configuration;
在边缘接入层的eNodeB节点中增加一个用户授权表(UAT，UserAuthorization Table)，用于记录该节点所接的用户的授权信息，通过该表的索引可以实现被授权用户的内容请求可以通过MCDN服务来满足；图8所示为本发明实施例UAT示意图，其中，所述标准优先级用于定义该内容请求的最低优先级，即只有用户优先级大于该请求的优先级才可以由MCDN服务满足，该属性可由第三方管理者通过SDN控制器更新。A user authorization table (UAT, UserAuthorization Table) is added to the eNodeB node of the edge access layer to record the authorization information of the user connected to the node. Through the index of the table, the content request of the authorized user can be passed through the MCDN service to meet; Figure 8 is a schematic diagram of the UAT embodiment of the present invention, wherein the standard priority is used to define the lowest priority of the content request, that is, only if the user priority is greater than the priority of the request can be served by the MCDN Satisfied, this attribute can be updated by a third-party manager through the SDN controller.
在实际应用中，所述基于所述内容请求关键信息及预设的UAT确定所述第一请求包符合第一授权条件，包括：In practical applications, the determining that the first request packet meets the first authorization condition based on the content request key information and the preset UAT includes:
将所述第一请求包对应的用户标识，即用户ID及内容名前缀分别与所述UAT中存储的用户标识及相应的内容名前缀进行匹配，当匹配成功时，即用户ID和内容名前缀同时匹配，确定所述第一请求包符合第一授权条件；Match the user ID corresponding to the first request packet, that is, the user ID and the content name prefix, respectively with the user ID stored in the UAT and the corresponding content name prefix, and when the matching is successful, that is, the user ID and the content name prefix Simultaneously matching, determining that the first request packet meets the first authorization condition;
当匹配失败时，确定所述第一请求包不符合第一授权条件，直接上报所述第一请求包至SDN控制器。When the matching fails, it is determined that the first request packet does not meet the first authorization condition, and the first request packet is directly reported to the SDN controller.
步骤704：基于所述优先级信息及预设的CCN转发策略判断所述第一请求包是否满足CCN转发条件。Step 704: Determine whether the first request packet satisfies the CCN forwarding condition based on the priority information and the preset CCN forwarding policy.
在一实施例中，上述操作具体包括：判断所述第一请求包对应的优先级是否不低于预设的所述第一请求包对应的标准优先级，也即判断所述第一请求包对应的优先级是否不低于所述第一请求包的请求内容对应的最低优先级，如果所述第一请求包对应的优先级不低于预设的所述第一请求包对应的标准优先级，确定所述第一请求包满足CCN转发条件；否则，确定所述第一请求包不满足CCN转发条件。In an embodiment, the above operation specifically includes: judging whether the priority corresponding to the first request packet is not lower than the preset standard priority corresponding to the first request packet, that is, judging whether the priority of the first request packet is Whether the corresponding priority is not lower than the lowest priority corresponding to the request content of the first request packet, if the priority corresponding to the first request packet is not lower than the preset standard priority corresponding to the first request packet level, determining that the first request packet satisfies the CCN forwarding condition; otherwise, determining that the first request packet does not satisfy the CCN forwarding condition.
步骤705：确定所述第一请求包满足所述CCN转发条件时，基于CCN通信模式对所述第一请求包进行CCN转发处理。Step 705: When it is determined that the first request packet satisfies the CCN forwarding condition, perform CCN forwarding processing on the first request packet based on the CCN communication mode.
这里，当确定所述第一请求包满足所述CCN转发条件时，为所述第一请求包对应的用户提供MCDN服务，即将所述第一请求包作为兴趣包进行标准的基于CCN通信模式的兴趣包处理流程，具体包括：将所述第一请求包首先匹配CS，如果CS中已经缓存了被请求内容(缓存命中)，则直接沿所述第一请求包的到达路径转发内容数据并丢弃该兴趣包；如果CS中没有被请求内容(缓存未命中)，则进一步匹配PIT，如果有PIT中有与所述第一请求包相同的内容名前缀，则在PIT的相应条目中增加所述第一请求包的到达接口，并丢弃所述第一请求包；如果PIT也没有匹配，则查找FIB，向所有匹配的端口转发所述第一请求包(所述第一请求包的到达接口不再转发)，并在PIT中记录所述第一请求包的到达接口；如果FIB也没有匹配条目，则丢弃所述第一请求包或者转发至默认接口。Here, when it is determined that the first request packet satisfies the CCN forwarding condition, the user corresponding to the first request packet is provided with an MCDN service, that is, the first request packet is used as an Interest packet to carry out a standard CCN-based communication mode The interest packet processing flow specifically includes: first matching the first request packet to the CS, and if the requested content has been cached in the CS (cache hit), forwarding the content data directly along the arrival path of the first request packet and discarding This interest packet; if there is no requested content in the CS (cache miss), then further match the PIT, if there is a content name prefix identical to the first request packet in the PIT, then increase the corresponding entry of the PIT The arrival interface of the first request packet, and discard the first request packet; if the PIT does not match, then search the FIB, forward the first request packet to all matching ports (the arrival interface of the first request packet is not Retransmit), and record the arrival interface of the first request packet in the PIT; if the FIB does not have a matching entry, then discard the first request packet or forward it to the default interface.
