Description
未知单播数据帧的处理方法、 路由装置及 TRILL网络系统 技术领域 Unknown unicast data frame processing method, routing device and TRILL network system
本发明涉及网络通信领或， 具体涉及一种 TRTLL ( Transparent Interconnection over Lots of Links , 多链接透明互连） 网络中未知单播数据 帧的处理方法、 路由装置及 TRILL网络系统。 背景技术 The present invention relates to network communication or, in particular, to a method, a routing device and a TRILL network system for processing an unknown unicast data frame in a TRTLL (Transparent Interconnection Over Lots of Links) network. Background technique
TRILL是 IETF (互联网工程任务组）推荐的连接层（ L2 ) 网络标准， 用于解决大型数据中心中 STP ( Spanning Tree protocol , 生成树协议 ) 的不 足。 在 L2网络中， STP通过阻塞冗余链路来避免环路， 但同时也造成了冗 余链路带宽的浪费 （被阻塞）。 TRILL通过将 IS-IS ( Intermediate System to Intermediate System )路由协议引入 L2网络， 解决了 L2环路问题， 同时保 留了 L2多路径 (或称为 ECMP ( Equivalent Cost Multiple Path路径 ) )。 TRILL is the connection layer (L2) network standard recommended by the IETF (Internet Engineering Task Force) to address the STP (Spanning Tree Protocol) in large data centers. In an L2 network, STP avoids loops by blocking redundant links, but it also creates a waste of redundant link bandwidth (blocked). TRILL solves the L2 loop problem by introducing an IS-IS (Intermediate System to Intermediate System) routing protocol into the L2 network, while preserving L2 multipath (or ECMP (Equivalent Cost Multiple Path)).
在 TRILL网络中， 运行 TRILL协议的设备称为 RBridge (路由网桥）。 在 TRILL网络的入口， 负责将发送端系统（End System ) 的单播数据帧封 装成 TRILL格式（即在原始数据帧前面添加 TRILL头和外部帧头， 封装后 的数据帧称为 TRILL数据帧 ) 并注入 TRILL网络的路由网桥称为 Ingress; 而在 TRILL网络的出口， 负责将 TRILL数据帧解封为原始数据帧并转发给 目的端系统的路由网桥称为 Egress。 除了 Ingress和 Egress外， 其他路由网 桥负责将 TRILL单播数据帧从 Ingress一跳一跳地传送到 Egress,称为传输 路由网桥。 In a TRILL network, the device running the TRILL protocol is called RBridge. At the entrance of the TRILL network, it is responsible for encapsulating the unicast data frame of the end system into a TRILL format (that is, adding a TRILL header and an outer frame header in front of the original data frame, and the encapsulated data frame is called a TRILL data frame). The routing bridge injected into the TRILL network is called Ingress. At the exit of the TRILL network, the routing bridge responsible for decapsulating the TRILL data frame into the original data frame and forwarding it to the destination end system is called Egress. In addition to the ingress and egress, other routing bridges are responsible for transmitting TRILL unicast data frames from the Ingress to the Egress, called the transport routing bridge.
当 Ingress收到一个未知单播数据帧 （Ingress在本地的 MAC ( Media Access Control )表中没有找 ill ill达目 MAC ( Media Access Control )地址 的 ECMP路径）时， 会以组播的方式对该数据帧进行 TRILL封装， 并沿着
一棵能够到达本地 TILL网络内所有路由网桥的分发树分发该数据帧。这会 使所有的路由网桥都会收到该数据帧， 从而确保了目的端系统能收到该数 据帧。 分发树上的每个路由网桥收到该数据帧后， 都会进行数据帧的解封 装（ TRILL解封装和 MAC解封装）， 以确认自己是否与目的 MAC地址所 在的端系统相连。 When Ingress receives an unknown unicast data frame (Ingress does not find the ECMP path of the ill ill destination MAC (Media Access Control) address in the local MAC (Media Access Control) table), it will multicast it. Data frames are TRILL encapsulated and along A distribution tree that can reach all routing bridges in the local TILL network distributes the data frame. This will cause all routing bridges to receive the data frame, thus ensuring that the destination system can receive the data frame. After receiving the data frame, each routing bridge on the distribution tree performs decapsulation (TRILL decapsulation and MAC decapsulation) of the data frame to confirm whether it is connected to the end system where the destination MAC address is located.
在 TRILL网络中， 路由网桥虽然可以通过 ESADI ( End Station Address Distribution Information ,端系统地址分发信息）协议分发本地的和学习远端 的端系统的 MAC地址信息， 但 ESADI协议只是一个可选协议， 并不是所 有的路由网桥都会实现该协议。 在没有 ESADI协议的情况下， 路由网桥只 能通过解封装 TRILL数据帧的方式（即自学习方式 ) 学习远端的 MAC地 址信息。 因此， 采用上述方式对未知单播数据帧进行处理时， 在初始阶段， TRILL 网络中会存在大量的未知单播数据帧， 而且每个路由网桥都会收到 这些数据帧， 因此会对每个路由网桥造成很大的数据帧处理负担， 甚至还 会造成丟报和重传， 造成传输路由网桥的资源的浪费和网络的带宽的浪费。 发明内容 In the TRILL network, although the routing bridge can distribute the MAC address information of the local and remote end systems through the ESADI (End Station Address Distribution Information) protocol, the ESADI protocol is only an optional protocol. Not all routing bridges implement this protocol. In the absence of the ESADI protocol, the routing bridge can only learn the remote MAC address information by decapsulating the TRILL data frame (ie, self-learning mode). Therefore, when the unknown unicast data frame is processed in the above manner, in the initial stage, there are a large number of unknown unicast data frames in the TRILL network, and each routing bridge receives these data frames, so each will The routing bridge causes a large data frame processing burden, and even causes packet loss and retransmission, resulting in waste of resources for transmitting the routing bridge and waste of network bandwidth. Summary of the invention

The invention will be further described below in conjunction with specific embodiments.
请参考图 1 ,传输路由网桥接收到分发树上游节点发送的数据帧为未知 单播数据帧后， 判断该传输路由网桥本地的地址表中是否存储有该数据帧 的目的端系统的位置信息， 经判断， 如果本地存储有该数据帧的目的端系 统的位置信息， 则该传输路由网桥将该数据帧处理后转发给所述目的端系 统或者与所述目的端系统相连接的路由网桥， 并终止该数据帧沿该传输路 由网桥的其他下游继续分发， 否则， 该传输路由网桥继续以组播的方式沿 该传输路由网桥的下游将接收到的未知单播数据帧继续分发， 下游的路由 网桥接收到该未知单播数据帧后， 以上述处理方法对其进行处理。 Referring to FIG. 1, after the transmission routing bridge receives the data frame sent by the upstream node of the distribution tree as an unknown unicast data frame, it determines whether the location of the destination system of the data frame is stored in the local address table of the transmission routing bridge. The information is judged, if the location information of the destination system of the data frame is stored locally, the transmission routing bridge processes the data frame and forwards the data to the destination system or the route connected to the destination system. The bridge, and terminating the data frame to continue to be distributed along the other downstream of the transport routing bridge, otherwise the transport routing bridge continues to multicast the unknown unicast data frame to be received downstream of the transport routing bridge After the distribution is continued, the downstream routing bridge receives the unknown unicast data frame and processes it according to the above processing method.
当传输路由网桥的下游有多个， 且该传输路由网桥的多个下游的路由 网桥与接收到的未知单播数据帧的目的端系统连接， 该传输路由网桥选取 最优的一个下游的路由网桥发送所述处理后的数据帧， 选取依据可为根据 各个下游的路由网桥到目的端系统的距离的长短、 或是各个下游的路由网 桥上的资源的消耗情况。 When there are multiple downstream of the transmission routing bridge, and the plurality of downstream routing bridges of the transmission routing bridge are connected to the destination end system of the received unknown unicast data frame, the transmission routing bridge selects an optimal one. The downstream routing bridge sends the processed data frame, and the selection may be based on the length of the distance from each downstream routing bridge to the destination end system, or the consumption of resources on each downstream routing bridge.
值得注意的是， 本例中路由网桥的下游是指该路由网桥到与之直接连 接的其他路由网桥的路径（如图 4中 RB2到 RB4之间的连线）， 例如， 路 由网桥 1与路由网桥 2、 3直接连接， 路由网桥 4与路由网桥 2直接连接， 路由网桥 5、 6与路由网桥 3直接连接， 则由路由网桥 1与路由网桥 2、 3 直接连接的路径为路由网桥 1的两个下游， 路由网桥 2、 3是路由网桥 1的 两个下游的路由网桥， 路由网桥 4是路由网桥 2的下游的路由网桥， 路由 网桥 5、 6是路由网桥 3的两个下游的路由网桥。 It is worth noting that, in this example, the downstream of the routing bridge refers to the path of the routing bridge to other routing bridges directly connected thereto (such as the connection between RB2 and RB4 in Figure 4), for example, the routing network. The bridge 1 is directly connected to the routing bridges 2, 3, the routing bridge 4 is directly connected to the routing bridge 2, and the routing bridges 5, 6 are directly connected to the routing bridge 3, and the routing bridge 1 and the routing bridge 2 are connected. 3 The direct connection path is the two downstream of the routing bridge 1, the routing bridges 2, 3 are the two downstream routing bridges of the routing bridge 1, and the routing bridge 4 is the routing bridge downstream of the routing bridge 2. The routing bridges 5, 6 are two downstream routing bridges of the routing bridge 3.
本例中， 传输路由网桥判断本地是否存储有接收到的未知单播数据帧 的目的端系统的位置信息包括：将接收到的未知单播数据帧的目的 MAC地 址与该传输路由网桥的 MAC表进行对比， 如果该传输路由网桥的 MAC表
中有与该未知单播数据帧的目的 MAC地址相对应的条目，则表明该传输路 由网桥存储有该未知单播数据帧的目的端系统的位置信息， 即该传输路由 网桥与该未知单播数据帧的目的端系统连接， 或是与到达该未知单播数据 帧的目的端系统路径上的下一目的路由网桥连接； 否则， 该传输路由网桥 未存储该未知单播数据帧的目的端系统的位置信息， 即该传输路由网桥在 本地的 MAC表中没有找到到达目的 MAC的 ECMP路径。 In this example, the transmission routing bridge determines whether the local location information of the received unknown unicast data frame is: the destination MAC address of the received unknown unicast data frame and the transmission routing bridge. MAC table for comparison, if the MAC table of the transmission routing bridge If there is an entry corresponding to the destination MAC address of the unknown unicast data frame, it indicates that the transmission routing bridge stores the location information of the destination system of the unknown unicast data frame, that is, the transmission routing bridge and the unknown The destination system of the unicast data frame is connected, or is connected to the next destination routing bridge on the path of the destination system that arrives at the unknown unicast data frame; otherwise, the transmission routing bridge does not store the unknown unicast data frame. The location information of the destination system, that is, the transmission routing bridge does not find the ECMP path to the destination MAC in the local MAC table.
如果经对比，发现传输路由网桥本地的 MAC地址表中有与接收到的未 知单播数据帧的目的 MAC地址相对应条目，则继续判断该对应的条目中的 Egress是否为该传输路由网桥本身， 如果是， 则表明该传输路由网桥直接 与接收到的未知单播数据帧的目的端系统相连接， 该传输路由网桥将该数 据帧解封后， 将得到的原始数据直接发给该目的端系统； 否则， 该对应条 目中的 Egress为与目的端系统相连接的其他路由网桥， 该传输路由网桥根 据对应条目中的 Egress 将接收到的未知单播数据帧以单播格式重新封装 后， 以单播的方式将其发给对应的下一目的路由网桥。 If it is found that the MAC address table of the transmission routing bridge has an entry corresponding to the destination MAC address of the received unknown unicast data frame, it is determined whether the Egress in the corresponding entry is the transmission routing bridge. In itself, if yes, it indicates that the transmission routing bridge is directly connected to the destination system of the received unknown unicast data frame, and the transmission routing bridge unblocks the data frame, and directly sends the obtained original data to The destination system; otherwise, the Egress in the corresponding entry is another routing bridge connected to the destination system, and the transmission routing bridge receives the unknown unicast data frame in a unicast format according to the Egress in the corresponding entry. After re-encapsulation, it is unicastly sent to the corresponding next destination routing bridge.
当然， 在传输网桥接收到上游节点组播的数据帧时， 首先须判断该数 据帧是否为未知单播数据帧， 如果是， 则按上述方法对其进行处理， 否贝' 继续沿着该传输路由网桥的下游分发该数据帧， 具体判断方法如下： Of course, when the transmission bridge receives the data frame multicasted by the upstream node, it first needs to determine whether the data frame is an unknown unicast data frame. If yes, it is processed according to the above method, and no The data frame is distributed downstream of the transmission routing bridge. The specific judgment method is as follows:
接收到组播到的数据帧时，解析该数据帧的外层 MAC头，对其做有效 性检查并获取上游邻居， 如果有效， 则继续解析该数据帧的 TRILL头， 进 一步检查该数据帧的完整性和有效性， 并获取分发树及 Ingress等信息， 如 果该数据帧完整并有效， 则进一步解析该数据帧的内层 MAC, 获取其目的 MAC地址， 然后根据 MAC地址编码规则， 判断获得的目的 MAC地址是 否为单播地址， 如果是， 则表明接收到的数据帧为未知单播数据帧， 按上 述方法对其进行处理； 否则， 接收到的数据帧为一般的组播数据帧， 该传 输路由网桥继续沿着其下游以组播的方式将接收到的数据帧分发出去。
下面， 结合图 2对发明做进一步详细的说明： When receiving the data frame that is multicast, the outer MAC header of the data frame is parsed, the validity check is performed, and the upstream neighbor is obtained. If valid, the TRILL header of the data frame is continuously parsed, and the data frame is further checked. Integrity and validity, and obtain information such as distribution tree and Ingress. If the data frame is complete and valid, further parse the inner MAC of the data frame, obtain its destination MAC address, and then determine the obtained MAC address encoding rule. Whether the destination MAC address is a unicast address, if yes, it indicates that the received data frame is an unknown unicast data frame, and is processed according to the above method; otherwise, the received data frame is a general multicast data frame, The transport routing bridge continues to distribute the received data frames along its downstream in a multicast manner. In the following, the invention will be further described in detail in conjunction with FIG. 2:
步驟 1：传输路由网桥从指定的接口接收 TRILL封装格式的组播数据帧； 步驟 2: 解析该数据帧的外层 MAC头， 获取上游邻居， 并判断该数据 帧的有效性， 如果经判断该数据帧为非法数据， 则将其丟弃， 进入下一数 据帧的传输环节， 否则， 进一步解析该数据帧的 TRILL头以获取分发树和 Ingress 等信息， 并检查该数据帧的完整性和有效性（比如邻居检查， 反向 路径检查等）， 如果为无效数据帧， 将其丟弃， 否则， 继续解析该数据帧的 内层 MAC帧， 获取其目的 MAC地址。 Step 1: The transmission routing bridge receives the multicast data frame in the TRILL encapsulation format from the specified interface. Step 2: Parse the outer MAC header of the data frame, obtain the upstream neighbor, and determine the validity of the data frame.

的端系统，上述路由装置将多个端系统连接，请参见图 4, H1-H6为端系统， RB1-RB8为上述路由装置， 图中， HI为发送端系统， H3为目的端系统， HI往 H3发送单播数据帧， RB1 (此时为 Ingress )并不知道 H3的位置， 于 是将 HI发送的原始数据帧封装成 TRILL组播数据帧沿分发树分发 (图中 虚线路径）， RB2收到该未知单播数据帧后， 经判断知道 H3与自己相连， 则将接收到的未知单播数据帧解封装为原始数据帧后转发给 H3, 然后终止 接收到的未知单播数据帧的继续向 RB2的下游分发，从而避免 RB4、 RB5、 RB7和 RB8对该数据帧的处理。 The embodiment also provides a TRILL network system, including multiple end systems and a plurality of the foregoing routing devices, wherein the multiple end systems included may be the transmitting end system or the mesh according to actual conditions. The end system, the above routing device connects multiple end systems, see Figure 4, H1-H6 is the end system, RB1-RB8 is the above routing device, in the figure, HI is the transmitting end system, H3 is the destination end system, HI Send a unicast data frame to H3. RB1 (in this case, Ingress) does not know the location of H3. Therefore, the original data frame sent by HI is encapsulated into a TRILL multicast data frame distributed along the distribution tree (the dotted path in the figure). After the unknown unicast data frame is determined, it is determined that H3 is connected to itself, and the received unknown unicast data frame is decapsulated into the original data frame and then forwarded to H3, and then the continuation of the received unknown unicast data frame is terminated.

The multicast data frame is distributed along the distribution tree (the dotted path in the figure). After receiving the unknown unicast data frame, RB2 determines that H6 is connected to its own downstream RB4 and RB5, and RB2 determines that RB5 to H6 are found. If the distance is smaller than RB4 to H6, the received unknown unicast data frame is re-encapsulated in unicast format and then forwarded to RB5, and then the received unknown unicast data frame is terminated and continued to be distributed to the downstream RB4, thereby avoiding RB4, RB7 processing of the data frame.
