Description

本地聚合链路处理方法及装置 技术领域
本申请涉及但不限于通信领域，尤指一种本地聚合链路处理方法及装置。
背景技术
多链路透明传输协议(Transparent Interconnection of Lots of Links，简称为TRILL)是国际标准的协议，该协议是多年逐步演变而来，将三层路由技术应用于二层传输，实现大规模二层云，满足日益增长的融合网络或超大型数据中心要求，构建一个优良而高效的二层广播域。TRILL使用终端地址交互协议(End Station Address Distribution Information，简称为ESADI)作为其一种可选协议完成端地址媒体接入控制(Media Access Control，简称为MAC)地址的学习。
ESADI是一种由中间系统到中间系统(Intermediate System to Intermediate System，简称为ISIS)衍化而来的端地址学习可选协议，但是具有相比流学习方式的更高优先级。ESADI协议通过TRILL协议的链路状态协议数据包(Label Switched Path，简称为LSP)交互协商，建立ESADI邻居后，每一个路由网桥(Routing Bridge，简称为RB)都产生ESADI的链路状态协议数据包(LSP)携带自己所可以到达的端地址，即MAC地址，并发送到网络中。只有将自己作为邻居的RB(路由网桥)，才会保存其ESADI的链路状态协议数据包(LSP)报文，形成链路状态数据库(Link State DataBase，简称为LSDB)。这样，这个RB就学习到ESADI邻居的端地址，即MAC地址。最终学习到的是TRILL的MAC地址表项就是<MAC；nickname>,表示本地(native)以太帧如果需要发送至这个MAC，可以选择TRILL单播发送至代号(nickname)的RB。
本地(native)多归接入是一种数据中心中非常常见的网络部署场景，终端通过两条或者两条以上的链路接入网络，形成一组多归链路接入的设备上的接口认为加入了同一链路聚合组，这些设备认为是同一链路聚合组内的成员设备。对于TRILL网络，终端通过多条链路通过多个连接路由网桥(ingress  RB)接入到TRILL网络，这些上行链路和ingress RB组成一个多归组，RB设备上运行了链路聚合协议。由于终端发出的报文可能会由多归组中的不同的RB进行封装，这样远端的出口RB进行MAC学习的时候，由于同一MAC只能学习到一个叠加网络设备标识的映射，会出现MAC表项的连接代号(Ingress-Nickname)频繁翻动(称为flip-flop)，造成MAC地址表的不稳定，甚至会引起返回流量的乱序与丢报，导致会话中断。
针对相关技术中，终端多归接入中MAC表项学习的flip-flop问题，目前还没有有效的解决方案。

下面结合可选实施例和实施方式对本申请进行详细说明。
本发明的可选实施例提供一种ESADI支持本地聚合链路组终端地址学习方法，要解决的技术问题是如何避免多归接入中MAC表项学习的flip-flop问题以及引发的流量问题，并可以实现到达目的MAC的负载分担。
技术方案如下：
1、如果第一RB(假设系统ID为1111.1111.1111)的第一接口上的一个VLAN x和第二RB(假设系统ID为2222.2222.2222)的第一接口上相同的VLAN x形成多归链路聚合组A，那么在第一RB的第一接口上绑定这个VLAN x属于多归链路聚合组A，表明第一RB第一接口在本VLAN x中属于多归链路聚合组A的成员。
2、如果第一RB(假设系统ID为1111.1111.1111)的第一接口上的一个VLAN x和第二RB(假设系统ID为2222.2222.2222)的第一接口上相同的 VLAN x形成了多归链路聚合组A之后，第一RB在此VLAN x对应的ESADI实例中通过ESADI-LSP发布多归链路聚合组信息，表明第一RB上本VLAN x中属于多归链路聚合组A。
3、在第一RB的VLAN x的ESADI实例中，在ESADI-LSP报文通过多归链路聚合组信息TLV发布多归链路聚合组信息。图6是根据本发明可选实施例的多归链路聚合组信息TLV图，如图6所示：多归链路聚合组(Multi-chassis Link Aggregation，MC-LAG)信息TLV包括一个字节类型(T，type)，一个字节的长度(L，length)和值(V，value)。值(V，value)中包含多个聚合链路组ITEM，每一个聚合链路组ITEM由两个字节的聚合链路组号和伪nickname。聚合链路组号填写为聚合链路组A，伪nickname填写为0。一个多归链路聚合组信息TLV可以在ESADI-LSP报文中出现多次。
4、第二RB的第二接口上也绑定这个VLAN x属于多归链路聚合组A，在第二RB的VLAN x的ESADI实例中收到第一RB发布的ESADI-LSP，包含了聚合链路组信息表明同属于聚合链路组A。此时，第二RB就会进行聚合链路组A的指定RB选举，选举系统ID大的作为指定RB，即第二RB为此聚合链路组的指定RB。
5、聚合链路组指定RB即第二RB为此聚合链路组指定伪nickname a，在第二RB的VLAN x的ESADI实例中，也会在第二RB的ESADI-LSP报文中通过多归链路聚合组信息TLV发布多归链路聚合组信息。此时，聚合链路组信息TLV中的聚合链路组号为A，伪nickname为a。
6、在第一RB的VLAN x的ESADI实例中收到第二RB发布的ESADI-LSP，包含了聚合链路组信息表明同属于聚合链路组A，也会进行聚合链路组A的指定RB选举，选举系统ID大的作为指定RB，即仍然第二RB为此聚合链路组的指定RB，自己失败。接受其第二RB发布的伪nickname a为第一RB上聚合链路组A的伪nickname a。
与相关技术相比，本发明的实施例需要专门的控制平面协议的扩展，只需要在控制面携带相应的多归接入链路绑定标识，实现原理简单。
以下通过两个应用场景进一步描述本发明的方法实施例。
应用场景一：
图7是根据本发明可选实施例的整体方案流程示意图，如图7所示，边界第一RB的接口1和第二RB的接口2通过跨设备的链路捆绑，提供给客户侧设备1(即图7中的host 1)的多归接入，构成一个多归链路聚合组1。系统ID分别为1111.1111.1111，2222.2222.2222都属于一个本地接入VLAN 1内。
在客户侧设备多归接入TRILL网络时，多归接入边界RB的接口会有相应的多归行为感知，如第一RB的SYSTEM ID为1111.1111.1111，第二RB的SYSTEM ID为2222.2222.2222。通过手工配置方式，在第一RB的接口1配置为binding vlan1 aggregation 1，即绑定第一RB的接口1属于聚合链路组1。同时，在第二RB的接口1配置为binding vlan1 aggregation 1，即绑定第二RB的接口1属于聚合链路组1。
这时第一RB和第二RB将会在vlan1对应的ESADI实例1的ESADI-LSP发布多归链路聚合组信息，多归链路聚合组TLV中的多归链路聚合组号填写为1，伪nickname填写为0。此时没有确定聚合链路组1的指定RB，伪nickname填写为0。
在第一RB收到第二RB的发布的ESADI-LSP，包含了聚合链路组信息表明同属于聚合链路组1。此时，第一RB就会进行聚合链路组1的指定RB选举，选举系统ID大的作为指定RB，因为第二RB的system-ID为2222.2222.2222，即第二RB为此聚合链路组1的指定RB，第一RB不做任何操作。
在第二RB收到第一RB的发布的ESADI-LSP，包含了聚合链路组信息表明同属于聚合链路组1。此时，第二RB就会进行聚合链路组1的指定RB选举，选举系统ID大的作为指定RB，因为第二RB的system-ID为2222.2222.2222，即第二RB选举自己为此聚合链路组1的指定RB，并指定这个聚合链路组1的伪nickname为1。在vlan1对应的ESADI实例1的ESADI-LSP发布多归链路聚合组信息，更新其多归链路聚合组TLV中的多归链路聚合组号填写为1，伪nickname填写为1。
在第一RB再次收到第二RB的发布的ESADI-LSP，包含了聚合链路组 信息表明同属于聚合链路组1，并且发现是聚合链路组1的指定RB发送过来的，并且伪nickname为1。
这样，对于同属于聚合链路组1的第一RB和第二RB协商成功，并且确定了这个聚合链路组在TRILL中的共同伪nickname。这样，在第一RB和第二RB接口1上vlan1收到客户侧发送来的本地(native)报文，将会在TRILL网络中使用伪nickname作为自己的源nickname进行数据发送。
应用场景二：
图8是根据本发明可选实施例的整体方案流程示意图，如图8所示，边界第一RB的接口1和第二RB的接口2通过跨设备的链路捆绑，提供给客户侧设备1的多归接入，构成一个多归链路聚合组1。系统ID分别为1111.1111.1111，2222.2222.2222都属于一个本地接入VLAN 1内。在TRILL网络的另一侧存在RB3，客户侧设备2接入，system-ID为3333.3333.3333，其中接口1也属于VLAN1，并且在接口1上存在一个终端接入。
在客户侧设备多归接入TRILL网络时，多归接入边界RB的接口会有相应的多归行为感知，如第一RB的SYSTEM ID为1111.1111.1111，第二RB的SYSTEM ID为2222.2222.2222。通过手工配置方式，在第一RB的接口1配置为binding vlan1 aggregation 1，即绑定第一RB的接口1属于聚合链路组1。同时，在第二RB的接口1配置为binding vlan1 aggregation 1，即绑定第二RB的接口1属于聚合链路组1。RB3的接口1上没有在vlan1中进行相应的绑定配置。
这时第一RB和第二RB将会在vlan1对应的ESADI实例1的ESADI-LSP发布多归链路聚合组信息，多归链路聚合组TLV中的多归链路聚合组号填写为1，伪nickname填写为0。此时没有确定聚合链路组1的指定RB，伪nickname填写为0。最终，这样，对于同属于聚合链路组1的第一RB和第二RB协商成功，并且确定了这个聚合链路组在TRILL中的共同伪nickname。
RB3的VLAN1对应的ESADI实例在接收到第一RB和第二RB在ESADI-LSP后，自始自终都在忽略第一RB和第二RB在ESADI-LSP发布多归链路聚合组信息，因为自己并没有在这个VLAN1中存在多归链路聚合组1。
在第一RB和第二RB接口1上vlan1收到客户侧设备1发送给第二RB的接入设备2(即图8中的host 2)的本地(native)报文，将会在TRILL网络中使用伪nickname 1作为自己的源nickname进行TRILL数据报文封装发送。同时，第三RB(RB3)需要发送给第一RB和第二RB的接入设备1的本地(native)报文时，填写目的nickname为伪nickname 1进行TRILL数据报文封装发送。

通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括多个指令用以 使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明实施例所述的方法。

可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行上述实施例的方法步骤。
可选地，本实施例中的示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
显然，本领域的技术人员应该明白，上述的本发明实施例的模块或步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的可选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有多种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
