Description

聚合端口报文转发方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种聚合端口报文转发方法及装置。
背景技术
通信网络设备中，负荷分担是一种通过多链路进行负载均衡的方法。形成负荷分担的接口称作聚合端口，聚合端口中的链路称作成员(或者成员链路)。如何选择成员转发报文，以及当已选择的成员失效时，如果进行成员保护，使承载在成员上的报文能够继续被转发，是负荷分担需要解决的问题。
对于负荷分担，是按照一定的算法计算(如哈希、轮询等)出报文的转发路径，然后通过聚合端口的相应成员转发出去。对于聚合端口的成员保护，当其中一个成员失效时，将报文承载到剩余成员上。通过算法计算报文转发路径的负荷分担方法，可以对报文进行有效的动态控制，也可以简化管理者的网络维护成本。
然而，发明人在研究过程中发现，在一些情况下，网络管理者希望了解特定的报文通过哪些成员被转发出去，以及希望能够通过管理员自己配置，使特定的报文被特定的成员转发出去。同时，也希望能够实施保护策略，当指定的成员失效时，能够通过指定成员的保护成员继续将报文转发出去。但是，现有的技术无法满足管理员指定转发成员及实施保护策略的需求。
针对相关技术无法满足管理员指定转发成员及实施保护策略需求的问题，目前没有提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在所写的说明书、权利 要求书、以及附图中所特别指出的结构来实现和获得。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明实施例提供了一种聚合端口报文转发方法，图1是根据本发明实施例的聚合端口报文转发方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，获取成员链路保护策略和/或子聚合端口保护策略，其中，成员链路保护策略包括：通过预设成员链路转发特定报文，并由预设成员链路的预设保护成员链路形成保护；子聚合端口保护策略包括：通过预设子聚合端口转发报文，并由预设子聚合端口的预设保护子聚合端口形成保护；
步骤S104，根据成员链路保护策略和/或子聚合端口保护策略，进行报文转发。
其中，上述的特定报文是指：具有预设的标识信息的报文，该标识信息可以随同成员链路保护策略一起下发，也可以单独由用户进行配置。上述的标识信息可以包括但不限于以下的特征：源因特网协议(IP)地址、目的IP地址、源多媒体接入控制(MAC)地址、目的MAC地址、源端口号、目的端口号。
在上述步骤中，在采用成员链路保护策略和/或子聚合端口保护策略时，可以通过用户的配置使得特定报文通过对应成员链路转发，或者使得聚合端口中形成预设子聚合端口对报文进行转发，相对于相关技术中直接通过计算的方式实现负荷分担的方式，通过本发明实施例的上述步骤，解决了相关技术无法满足管理员指定转发成员及实施保护策略需求的问题，提高了聚合端口报文转发的灵活性。
下面分别对两种保护策略进行说明。
方式一：成员链路保护策略
优选地，在采用成员链路保护策略进行报文转发时，在步骤S104中可以采用下列方式：通过预设成员链路转发特定报文；在预设成员链路失效的情况下，通过预设保护成员链路转发特定报文。即，对于特定报文而言，转发链路以及该转发链路的保护链路都可以是预先配置的。此外，本发明实施例中，对成员链路保护策略或者子聚合端口保护策略的配置过程中，可以采用成员链路标识与特定报文的标识信息相应设置的方式进行配置。
优选地，在某些情况下可能会出现预设成员链路、预设保护成员链路均失效的情况，为了保障报文的转发性能，在步骤S104中还可以在预设成员链路、预设保护成员链路均失效的情况下，通过聚合端口中的其他成员链路转发特定报文。较优的，在采用其他成员链路转发特定报文时，可以按照普通负荷分担方式进行转发。
方式二：子聚合端口保护策略
优选地，在采用子聚合端口保护策略进行报文转发时，在步骤S104中可以采用下列方式：通过预设子聚合端口转发报文；在预设子聚合端口失效的情况下，通过预设保护子聚合端口转发报文。即将聚合端口中的部分成员链路配置为预设子聚合端口，并优先通过预设子聚合端口转发报文。
优选地，为了进一步增强报文转发的灵活性，在本发明实施例中还提供了一种对预设子聚合端口配置相应的特定报文，并在预设子聚合端口中转发特定报文的方式，例如：配置预设子聚合端口对应的特定报文；通过预设子聚合端口转发特定报文；在预设子聚合端口失效的情况下，通过预设保护子聚合端口转发特定报文。
优选地，在某些情况下可能会出现预设子聚合端口、预设保护子聚合端口均失效的情况。为了保证报文的转发性能，在步骤S104中还可以在预设子聚合端口、预设保护子聚合端口均失效的情况下，通过聚合端口中的其他成员链路转发报文或者特定报文。
需要说明的是，上述方式一和方式二可以单独实施，但在不冲突的情况下，也可以结合实施，例如在方式二中的预设子聚合端口中进行报文转发时，采用方式一的方式，而不采用普通负荷分担的方式。
优选地，在方式二中，在通过预设子聚合端口或者预设保护子聚合端口转发报文或者特定报文的情况下，按照普通负荷分担方式转发报文或者特定报文。
在本实施例中还提供了一种聚合端口报文转发装置，用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述，下面对该装置中涉及到的模块进行说明。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
