Description

一种TRILL网络MAC地址学习的方法及装置
本申请要求2015年12月09日提交的申请号为：201510907128.0、发明名称为“一种TRILL网络MAC地址学习的方法及装置”的中国专利申请的优先权，其全部内容合并在此。
技术领域
本发明涉及通信技术领域，尤其涉及一种TRILL网络MAC地址学习的方法及装置。
背景技术
为了解决生成树协议的带宽浪费、收敛慢等问题，互联网工程任务组(IETF，Internet Engineering Task Force)制定多链路透明互联(TRILL，TRansparent Interconnection of Lots of Links)协议将三层路由技术中间系统到中间系统(IS-IS，Intermediate System-to-Intermediate System)的设计思路引入二层网络，并对其进行了必要的改造，从而将二层的简单、灵活性与三层的稳定、可扩展和高性能有机融合起来。
运行TRILL协议的设备称为路由网桥(RB，RBridge)。在TRILL网络的出入口，RBridge需要对端系统(ES，End System)提供服务，因此需要对ES的MAC(Media Access Control，媒体介入控制)地址 信息有一定了解。目前，RBridge获取MAC信息的方式主要有：1)自学习方式：通过TRILL数据帧的封装/解封装学习MAC地址信息；2)启用ESADI协议，相互通告和学习MAC信息；3)通过端系统注册的方式学习MAC信息。其中，启用ESADI的RBridge主动发布本地的MAC信息，能及时了解其他RBridge上的MAC信息变化，是RBridge之间交互MAC信息的主要方式之一。
但是，在现有技术中，TRILL协议本身使用了IS-IS(Intermediate System-to-Intermediate System，中间系统到中间系统)的机制来发布信息，而ESADI作为TRILL协议的附属协议，也借用了IS-IS的机制来发布MAC信息，这就形成了很大程度的代码冗余，也带来系统资源的浪费。

具体实施方式
下面结合附图和具体实施例对本发明一种TRILL网络MAC地址学习的方法及装置进行详细说明。
实施例一
在TRILL网络中，路由网桥学习MAC地址并洪泛到邻居路由网桥的过程中，由于端系统相连的路由网桥学习端系统的MAC地址，然后由该路由网桥向除了接收端外的邻居路由网桥发送携带有MAC地址的链路状态包。简单来说，即路由网桥学习端系统的MAC地址，把所学到的MAC地址封装在特殊的链路状态包中，洪泛到邻居路由网桥中。邻居路由网桥收到该链路状态包，进行一些检查并继续往邻居洪泛。
具体来说，如图1所示，一种TRILL网络MAC地址学习的方法，包括步骤：
与ES(End System，端系统)相连的RB(RBridge，路由网桥)学习所述端系统的MAC地址，并将所述MAC地址以TLV(具体为MAC-Reachability TLV)形式封装在ID为0000.0000.0000.00-00的LSP(Link-State Packet，链路状态包)中，周期性的向邻居路由网桥发送；
当邻居路由网桥接收到LSP后，判断本地是否存在链路状态包中的MAC地址；
若不存在，学习该MAC地址，设置该网桥的置信值为接收到的MAC地址的置信值；
若存在，更新本地MAC地址的置信值为接收到的值；
将链路状态包中MAC地址的置信值加1，并向除接收端外的所有邻居发送。
具体来说，在TRILL网络MAC地址学习方法中，首先要与端系统相连的路由网桥学习端系统的MAC地址，并将该MAC地址封装在链路状态包中，周期性的向邻居路由网桥发送。在该过程中，路由网桥学习到端系统的MAC地址后，将该MAC地址以MAC-Reachability TLV形式封装在ID为0000.0000.0000.00-00的链路状态包中。当邻居路由网桥接收到该链路状态包后，判断本地是否存在链路状态包中的MAC地址，如果存在，更新本地MAC地址的置信值为接收到的值；若不存在，学习该MAC地址，设置本地的置信值为接收到的MAC地址的置信值。之后，将链路状态包中MAC地址的置信值加1，并向除接收端外的所有邻居发送。
其中，如图2所示，更新本地MAC地址的置信值为接收到的值的过程包括步骤：
判断本地MAC地址的置信值(Confidence)是否大于接收到的MAC地址的置信值；
若是，更新本地的MAC地址的置信值为接收到的MAC地址的置信值，然后执行步骤将链路状态包中MAC地址的置信值加1，并向除接收端外的所有邻居发送；
若不是，不更新本地MAC地址的置信值，但是当更新周期到期时，将链路状态包中MAC地址的置信值加1，再往除接收端外所有邻居发送更新后的MAC地址。
具体来说，当本地存在数据链路包中的MAC地址时，将本地MAC地址的Confidence(置信值)与接收MAC地址的Confidence进行比较，比本地小则更新本地MAC地址的Confidence为接收到的值，比本地大则不更新。更新本地MAC地址后，把TLV中的Confidence字段加1，再往除接收端外所有邻居发送；Confidence达到255后，则不再往外发送。
值得指出的是，在本实施例中，如果本地MAC地址的置信值小于接收到的数据链路包中的MAC地址的置信值，先不更新本地MAC地址的置信值。但是，待更新周期到期时，将本地MAC地址的置信值加1，然后再往除接收端外的所有邻居发送本地的MAC地址。TRILL网络中，所有的路由网桥都进行上述操作后，端系统的MAC信息能够同步至网络中的所有设备中。
更进一步，对一种TRILL网络MAC地址学习的方法的总体概述为：
步骤1：RB学习到ES的MAC后以MAC-Reachability TLV形式封装在ID为0000.0000.0000.00-00的LSP中，周期性往所有邻居路由网桥发送；
步骤2：路由网桥收到LSP后，对TLV中每一个MAC地址，首先检查本地是否存在该MAC地址。如果本地不存在该MAC地址，则进行学习该MAC地址，其Confidence为接收到的值；如果存在，则将本地MAC地址的Confidence与接收MAC地址的Confidence进行比较，比本地小则更新本地MAC地址的Confidence为接收到的值， 比本地大则不更新。更新本地MAC地址后，把TLV中的Confidence字段加1，再往除接收端外所有邻居发送；Confidence达到255后，则不再往外发送；
步骤3：所有的路由网桥都进行步骤1和步骤2动作，使得端系统的MAC信息同步到网络中的所有设备。
本实施例利用IS-IS(Intermediate System-to-Intermediate System，中间系统到中间系统)的洪泛机制来发布MAC地址，通过逐个路由网桥增加置信值的机制，防止了链路状态包的无限循环。该方法不影响原有的TRILL链路状态数据库同步，不依赖TRILL路由，实现方式简单，节省了系统资源。
实施例二

具体来说，本地存在所述链路状态包中的MAC地址时，首先由判断单元判断本地MAC地址的置信值是否大于接收到的所述链路状 态包中的MAC地址的置信值，若是，更新单元将所述本地MAC地址的置信值更新为所述链路状态包中的MAC地址的置信值，之后由增加模块将所述链路状态包中的MAC地址的置信值增加1；否则，不更新所述本地MAC地址的置信值，然后当更新周期到期时，周期单元将所述链路状态包中MAC地址的置信值加1，再往除接收端外所有邻居发送更新后的所述链路状态包。
对于本领域的技术人员而言，阅读上述说明后，各种变化和修正无疑将显而易见。因此，所附的权利要求书应看作是涵盖本发明的真实意图和范围的全部变化和修正。在权利要求书范围内任何和所有等价的范围与内容，都应认为仍属本发明的意图和范围内。
