Description

一种聚合端口的介质访问控制地址保活装置及方法 技术领域
本发明涉及介质访问控制 (MAC, Media Access Control )地址保活技 术,特别是指一种分布式二层网络设备中的聚合端口的 MAC地址保活装置 及方法。 背景技术
MAC地址是识别局域网 (LAN, Local Area Network )节点的标识, MAC地址对设备如网卡接口是全球唯一的。 MAC地址为 48位, 用 12个 16进制数表示。 前 6个 16进制数由美国电气和电子工程师协会(IEEE, Institute of Electrical and Electronics Engineers ) 管理, 用来识另 ll生产者或者 厂商, 构成组织唯一识别符(OUI, Organizational Unique Identifier ); 后 6 个 16进制数包括网卡序列号、 或者特定硬件厂商的设定值。
下面介绍一下与 MAC地址相关的 MAC地址学习、保活和老化。首先, MAC地址学习, 是指将每个所接收的报文的源 MAC地址存储在学习虚拟 局域网 (VLAN, Virtual Local Area Network )里, 使包含该地址的报文只 会转发到此地址所在端口;而对于发至未学习地址的报文,则转发到 VLAN 的所有端口上。 这个方法有助于把相连局域网的业务量最小化; MAC地址 的作用, 是为了让报文到达设备之后转发至指定的端口, 进而减小局域网 内的业务量。 但是每个 MAC 地址都需要占用实际的软硬件资源, 当某个 MAC地址没有存在的必要时, 经过一段时间之后, 就要将该 MAC地址删 除掉并释放软硬件资源, 这称之为 MAC地址老化; 如果在这段时间中, 设 备又收到了包含该 MAC地址的报文, 那么由于这个 MAC地址已经存在, 所以就不用被学习,也不能被老化, 这个时候要做的动作就是 MAC地址保 活。
在上面三个动作中, 保活动作的使用最为频繁。 举个最简单的例子, 早晨上班开电脑做了一次 MAC地址学习, 晚上下班关电脑做一次 MAC地 址老化, 中间 8个小时内, 可以以分钟为单位设定每隔一分钟做一次 MAC 地址保活。
对于图 1所示的分布式网络设备, 在子系统 1 , 端口 12上学习到一个 MAC地址之后, 需要将该 MAC地址通过中央处理模块的子系统同步模块 同步到其他所有的子系统上去, 这样才能保证其他子系统收到包含该 MAC 地址的 文之后, 能将该 ^艮文转发到学习到该 MAC地址的对应端口上, 即 子系统 1的端口 12。
在一段时间之内,如果子系统 1端口 12上一直能够接收到包含该 MAC 地址的报文, 则需要在所有的子系统上保留该 MAC地址,但是保活的动作 只能在子系统 1端口 12收到该 MAC地址的 ^艮文时在子系统 1上保活, 而 其他子系统由于无法收到这样的报文, 就会有一个 MAC地址 "假老化" 的 过程, 但是此时硬件 MAC表中该地址项是存在的, 软件在接收到这个 "假 老化" 消息后, 判断硬件 MAC表中该 MAC地址所对应的端口是否在本子 系统上, 如果不是在本子系统上, 则不理会这个 "假老化" 消息, 所以在 其他子系统上的该 MAC地址不会被删除; 如果子系统 1上的 MAC地址没 有被保活, 则会通知 MAC表管理模块, 由 MAC表管理模块删除所有子系 统上相应的 MAC地址。
但是在二层网络设备中会存在一种聚合端口, 这种聚合端口是一个逻 辑概念, 是一系列物理端口的集合, 并且一个聚合端口中的成员物理端口 可以在不同的子系统上, 在聚合端口上学习到 MAC地址后, 与该 MAC地 址所对应的端口就是一个聚合端口, 而不是某个物理端口。
现有技术中 ,对于上面所述的物理端口 MAC地址保活原则就不适用于 二层网络设备的聚合端口, 因为聚合端口很可能不独属于任何一个子系统。 一个聚合端口的成员物理端口往往同时属于多个子系统, 如果按照物理端 口所属子系统进行 MAC地址保活,除非在所有子系统上均有这个聚合端口 的成员物理端口, 并且所有成员物理端口都能收到用来保活的报文, 否则, 必然使某个子系统上对应的该 MAC地址没办法被保活, 而且, 也不能像物 理端口处理 艮老化" 一样, 通过判断端口所属子系统来否决 艮老化" 消息。 如此, MAC表管理模块就会删除这个本无需删除的 MAC地址; 当 该 MAC地址被删除之后, 以该 MAC地址为目的地址的报文就会在二层网 络设备上洪泛, 从而增加带宽占用率。 发明内容
有鉴于此,本发明的主要目的在于提供一种聚合端口的 MAC地址保活 装置及方法, 以避免聚合端口的 MAC地址被误删及以该 MAC地址为目的 地址的报文在二层设备上洪泛, 从而节约带宽占用率。

所述 MAC保活消息收发模块, 位于子系统中, 用于在 MAC地址老化 周期内, 向全局聚合端口 MAC地址管理模块发送 MAC保活消息, 以及接 收全局聚合端口 MAC地址管理模块发送的 MAC保活消息。

所述 MAC保活消息发送给所有子系统后, 该方法还包括: 保活所有子 系统中该 MAC地址。
如果子系统没有在 MAC 地址老化周期内收到报文, 该方法进一步包 括: 未收到报文的子系统老化该 MAC地址。
以上所述 MAC保活消息中包含: 源 MAC地址和子系统的名称。
釆用本发明提供的装置及方法, 可以在 MAC地址老化周期内,保活聚 合端口的 MAC地址, 有效避免由于聚合端口的 MAC地址的误删而导致的 目的报文在二层网络设备上的洪泛;另外,还可以老化不必要的 MAC地址, 有效节省了网络带宽占用率, 从而节约了系统资源。 附图说明

图 3为本发明聚合端口的 MAC地址保活方法流程图。 具体实施方式
本发明的基本思想是:在 MAC地址老化周期内收到报文的子系统向全 局聚合端口 MAC地址管理模块发送 MAC保活消息; 全局聚合端口 MAC 地址管理模块将接收到的 MAC保活消息发送给所有子系统以保活该 MAC 地址。 本发明所提供的聚合端口的 MAC地址保活装置, 如图 2所示, 该装置 包括:全局聚合端口 MAC地址管理模块和 MAC保活消息收发模块;其中, 全局聚合端口 MAC地址管理模块, 位于网络设备的中央处理模块中, 用于在 MAC地址老化周期内, 接收子系统发送的 MAC保活消息, 并将该 MAC保活消息发送给所有子系统。
MAC保活消息收发模块, 位于子系统中, 用于在 MAC地址老化周期 内, 向全局聚合端口 MAC地址管理模块发送 MAC保活消息, 以及接收全 局聚合端口 MAC地址管理模块发送的 MAC保活消息。
该装置还包括: 位于网络设备的中央处理模块中的子系统同步模块和 MAC表管理模块; 其中,
子系统同步模块,用于将一个子系统学习到的聚合端口的 MAC地址同 步到其他子系统上;
MAC表管理模块, 用于保活或老化聚合端口的 MAC地址。
基于上述装置, 本发明还提供了一种聚合端口的 MAC地址保活方法, 如图 3所示, 该方法包括以下步骤:
步骤 301 : 启动全局聚合端口 MAC地址管理模块;
步骤 302: 是否有子系统学习到聚合端口的 MAC地址, 如果有子系统 学习到聚合端口的 MAC地址, 则执行步骤 303; 否则, 继续执行步骤 302; 本步骤中, 通过手动配置实端口和虚端口以组成聚合端口, 由于在实 端口上学习到的 MAC地址会自动学习到虚端口上,所以可以判断出是否学 习到聚合端口的 MAC地址, 其中该过程为现有技术。
步骤 303: 将该 MAC地址同步到所有子系统上;
本步骤中,通过中央处理模块的子系统同步模块将该 MAC地址同步到 其他子系统上 ,该 MAC地址对应的端口为该聚合端口。此步骤为现有技术 , 在此不做详细描述。 步骤 304: 子系统判断是否在 MAC地址老化周期内收到报文, 如果收 到报文, 执行步骤 305; 否则执行步骤 308;
本步骤中, 子系统在 MAC地址老化周期内收到的报文中包含源 MAC 地址, 用于保活该 MAC地址。
步骤 305: 收到报文的子系统向全局聚合端口 MAC地址管理模块发送 MAC保活消息;
本步骤中, 全局聚合端口 MAC地址管理模块收到的 MAC保活消息中 包含: 源 MAC地址和子系统的名称。
步骤 306: 全局聚合端口 MAC地址管理模块将接收到的 MAC保活消 息发送给所有子系统;
步骤 307: 保活所有子系统中该 MAC地址, 返回步骤 304;
本步骤中, 可以通过中央处理模块中的 MAC表管理模块实现 MAC地 址的保活, 其中, 该方法为现有技术, 在此不做详细描述。
步骤 308: 未收到报文的子系统老化该 MAC地址, 返回步骤 302。 本步骤中, 可以通过 MAC表管理模块实现 MAC地址的老化, 从而实 现所有子系统中该 MAC地址的老化, 其中, 该方法为现有技术, 在此不做 详细描述。
本发明中, MAC地址的保活是由全局聚合端口 MAC地址管理模块向 所有子系统发送 MAC保活消息, 以实现所有子系统的 MAC地址保活; 而 MAC地址的老化是未在 MAC地址老化周期内收到报文的子系统实现的对 本子系统 MAC地址的老化, 原则上各子系统实现的 MAC地址的老化周期 相同。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围, 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等, 均应包含在本发明的保护范围之内。
