Description

一种端口配置管理方法、 单板及端口配置管理系统
本申请要求于 2008 年 9 月 10 日提交中国专利局、 申请号为 200810216204.3、 发明名称为"一种端口配置管理方法、 单板及端口配置管理 系统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信设备, 尤其涉及一种端口配置管理方法、单板及端口配置 管理系统。
背景技术
在很多电信设备中, 为了提高软硬件的可靠性, 通常会采用主备机制: 即 将一块单板作为主板, 另一块单板作为该主板的备板,将主板的数据备份到备 板。 如果当前工作的主板坏了, 可以将主板的业务倒换到备板, 备板成为主板 继续工作, 以保证业务不中断。
如图 1所示, 是现有的一种单板主备结构的示意图, 其中, 两块单板是独 立的主板, 由应用层来约束两块单板的主备关系。主板侧应用层每次将配置管 理通过备份通道备份到备板应用层。 一旦检测到主板坏掉, 则进行倒换操作, 备板侧应用层将所有应用层备份的操作全部下发执行, 备板升为主板开始工 作。
在这种结构中, 由于两块单板均是独立的主板, 只是应用将其绑定在一起 形成主备关系, 因此主板协商出来的稳态数据没法备份到备板中去,如果发生 主备倒换的话, 则需要重新协商这些稳态数据。 如此在一些应用中, 例如在无 线业务中, 可能会存在掉话, 或者在路由器转发出现数据包丢失。 这种备份结 构, 在一些应用中相当于备板没有真正起到备份的作用。
如图 2所示,是现有的另一种单板主备结构的示意图。该图 2示出了采用镜 像备份的机制。 此处所称镜像备份为: 将主板上所有的数据备份到备板, 并且 在主板实时操作和实际运行中,也将相关实时操作和稳态数据备份到备板, 以 实现主板和备板数据一致, 故称之为"镜像", 以保证在进行主备倒换之后业务 不中断。
这种镜像备份机制能满足主备倒换后业务不中断,但由于在主板工作的时 候, 备板不参与处理业务数据, 即不处理备板业务端口接收上来的报文, 故没 法做到主板与备板之间的端口备份, 若是主板上的部分端口不能工作, 例如端 口损坏和端口连接的链路断掉, 则需要将整个主板进行倒换, 这样才能保证与 之有关的业务不中断。
发明内容

本发明实施例提供的一种用于端口配置管理的单板, 包括: 配置信息接收 模块, 用于接收端口配置信息; 端口位置确定模块, 用于根据配置信息接收模 块接收的所述端口配置信息确定对应的端口的物理位置; 数据处理模块, 用于 在所述端口位置确定模块确定所述端口配置信息对应的端口的物理位置在第 一单板时, 根据所述端口配置信息对所述第一单板对应的端口进行配置管理; 以及用于在所述端口配置信息对应的端口的物理位置在所述第二单板上时,将 所述端口配置信息发送给所述第二单板,并根据所述端口配置信息对所述第二 单板对应的端口进行配置管理。
本发明实施例提供的一种端口配置管理系统, 包括: 相互连接的第一单板 和第二单板, 所述第一单板接收端口配置信息, 并确定所述端口配置信息对应 的端口的物理位置,如果所述端口配置信息对应的端口的物理位置在第一单板 上, 则根据所述端口配置信息对所述第一单板对应的端口进行配置管理,如果 所述端口配置信息对应的端口的物理位置在第二单板上,则将所述端口配置信 息发送给所述第二单板; 所述第二单板接收来自所述第一单板的端口配置信 息, 并根据所述端口配置信息对所述第二单板对应的端口进行配置管理。
本发明实施例可以对第一单板的端口与第二单板的端口进行统一管理,且 端口备份和单板备份相互独立,不会因为单板上的一个端口不可用而进行主备 单板的倒换, 并提高可靠性。

根据该通信设备的组网需求,配置第一单板的端口与第二单板的端口之间 端口备份关系,或者端口之间的负荷分担策略,其中,一些端口作为主用端口, 另一些端口作为与该主用端口对应的备用端口,在本发明实施例中, 该主用端 口在第一单板上,该备用端口可以在第一单板上,也可以在第二单板上,此外, 主用端口和备用端口的对应关系可以为 1+1 , 即一个主用端口对应一个备用端 口, 也可以为 N+1 , 即 N个主用端口对应 1个备用端口。
下面结合具体例子, 对上述的各过程进行详细说明。 为便于说明, 假设第 一单板有 8个业务端口, 第二单板也有为 8个业务端口, 因此第一单板所管理 的端口数量总共为 16, 假设编号为 0~15, 其中编号为 0~7为第一单板物理上 的 0 ~ 7端口, 编号为 8 ~ 15对应第二单板上的端口, 分别映射到第二单板物 理上的 0 ~ 7端口。
如图 8所示, 是在本发明实施中第一单板侧进行端口配置的流程图。
S80,接收端口配置信息,该端口配置信息可以在第一单板的应用层生成, 该端口配置信息可以是给端口分配置的 IP地址等, 并且携带有相应端口的编 号 (如 0~15中的任一个或多个);
S82, 根据端口配置信息中的端口编号来确定该端口配置信息对应的端口 的物理位置。 例如, 如果在端口配置信息中该端口编号为 0, 其处于第一单板 的 0~7端口范围之内, 则表示为第一单板的端口; 如果该端口编号为 9, 其处 于第二单板的 8~15端口范围之内, 则表示为第二单板上的端口。
S84, 如果该端口配置信息对应的端口为第一单板的端口, 则存储该端口 配置信息, 并将该端口配置信息向第一单板的底层下发,对该端口配置信息对 应的端口进行配置管理。
S86, 如果该端口配置信息对应的端口是第二单板的端口, 在第一单板中 存储该端口配置信息, 并将该端口配置信息发送给第二单板。
S88, 不管该端口配置信息对应的端口是第一单板的端口还是第二单板的 端口,均需要将端口配置管理的信息通过备份通道在第一单板和第二单板中进 行备份操作。
如图 9所示, 是在本发明实施中第二单板侧进行端口配置的流程图。
S90, 第二单板接收来自第一单板的端口配置信息;
S92, 对端口配置信息的端口编号进行偏移操作, 根据偏移后的端口编号 确定端口配置信息对应的端口在第二单板上的物理位置,并将该端口配置信息 下发到第二单板的底层, 对相应端口进行配置管理。 例如: 假设端口配置信息 所对应的端口编号为 9, 因为编号为 8 ~ 15对应第二单板上的端口, 所以该端 口配置信息所对应的端口是第二单板的端口, 进行偏移操作, 即其映射到第二 单板物理上的 0~7端口的 1端口。
通过图 8与图 9的流程,第一单板与第二单板之上均存储有所有端口的端 口配置信息, 即使发生第一单板与第二单板的主备倒换,也不会丢失这些端口 配置信息。
如图 10所示, 是本发明实施例中第一单板侧的控制面报文处理流程图; S100, 接收控制面报文, 该控制面报文为第一单板的应用层所产生的, 例 如 ping报文;
S102, 根据所述控制面报文中的信息, 确定出端口号, 例如根据 ping报 文中的目的 IP地址可以确定对应的出端口号, 并判断该出端口是否为第一单 板的端口;
S104,如果判断结果为该出端口是第一单板的端口, 则将所述控制面报文 经该出端口发送出去;
S106,如果判断结果为该端口是第二单板的端口,将所述控制面报文通过 数据通道发送给第二单板。
如图 11所示, 是本发明实施例中第二单板侧的控制面报文处理流程图; S110, 接收来自第一单板的控制面报文, 如 ping报文;
S112,对所述控制面报文中的出端口号进行偏移处理,确定在第二单板的 出端口;
S114, 将所述控制面报文经所述确定的第二单板的出端口发送出去。
如图 12所示, 是本发明实施例中第一单板侧的接收报文的处理流程图; S120,接收来自第一单板的端口或来自第二单板的报文,在具体的实例中, 可以采用标记位来区别该报文是来自第一单板还是来自第二单板; 然后需要判断该所接收的报文所需要的处理方式, 具体为:
S121 , 判断该接收的报文是否为需要本地处理的报文。
如果判断结果为是, 则在 S122中将该报文传送给第一单板的上层进行相 应处理, 否则进入 S123;
S123 , 判断该接收的报文是否需要转发;
如果判断结果为是, 则流程转入 S125 , 否则在 S124中丢弃该 ^艮文; S125 , 判断该报文是否需要在第一单板上进行转发;
如果判断结果为是, 则在 S126中, 根据第一单板的转发表, 将该报文发 送给第一单板的相应端口, 进行转发;
否则, 在 S127中, 通过数据通道将该报文转发给第二单板; 在此步骤中, 如果该报文是来自第二单板, 则直接丢弃, 以避免重复转发。
如图 13所示, 是本发明实施例中第二单板侧的接收报文的处理流程图;
5130,接收来自第二单板的各端口或来自第一单板的报文,在具体的实例 中, 可以采用标记位来区别该报文是来自第二单板还是来自第二单板;
然后判断该所接收的报文所需要的处理方式, 具体为:
5131 , 判断该接收的报文是否为需要本地处理的报文。
如果判断结果为是, 则在 S132中将该报文传送给第二单板的上层进行相 应处理, 否则进入 S133;
S133 , 判断该接收的报文是否需要转发;
如果判断结果为是, 则流程转入 S135 , 否则在 S134中丢弃该 ^艮文; S135 , 判断该报文是否需要在第二单板上进行转发;
如果判断结果为是, 则在 S136中, 根据第二单板的转发表, 将该报文发 送给本单板的相应端口, 进行转发;
否则, 在 S137中, 通过数据通道将该报文转发给第一单板; 在此步骤中, 如果该报文是来自第一单板, 则直接丢弃, 以避免重复转发。
另外, 本发明的实施例还可以包括如下的步骤:
检查主用端口的状态;
当检查到主用端口出现故障或主用端口所连接的链路出现故障,则将主用 端口的业务切换至与主用端口相关联的备用端口上,这样可保证在不进行单板 主备倒换的情况下主备业务的倒换, 并保证业务不中断。
在本发明的实施例中, 端口备份和单板备份采用相互独立的机制, 不会因 为主板一个端口不可用而进行单板的主备倒换,只需采用端口的主备倒换即可 实现业务的连续性;
另外, 能够进行主板与备板间的端口备份, 提高可靠性; 还可以进行主板 与备板间的端口负荷分担, 减轻端口负荷。
通过以上的实施方式的描述,本领域的普通技术人员可以清楚地了解到本 发明实施例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 硬件来实现。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,该计算机软件产品可以存储在存储介质中,如 ROM/RAM、磁碟、 光盘等, 包括若干指令用以使得一台计算机设备、 或者服务器、 或者其他网络 设备执行本发明各个实施例或者实施例的某些部分所述的方法。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发 明的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发 明的保护范围之内。
