Description

报文处理方法、装置及路由器 技术领域
本公开涉及通信领域，具体而言，涉及一种报文处理方法、装置及路由器。
背景技术
随着互联网的飞速发展，当前的互联网协议版本4(Internet Protocol version 4，简称为IPv4)地址协议定义的地址空间正在面临即将耗尽的危险。互联网协议版本6(Internet Protocol version 6，简称为IPv6)的出现，极大地增大了网络地址空间，能够很好地解决IPv4地址空间即将耗尽的问题。
作为IPv4宽带接入中常用的冷备技术，在IPv6的使用中遇到了问题。例如，IPv6的邻居发现协议(Neighbor Discovery Protocol，简称为NDP)协议使得获取地址和网关更为灵活，在双机冷备组网中，用户获取的地址和网关都带有不确定性。
双机冷备组网中IPv6用户无状态获取地址时，当用户发送组播路由通告(Router Solicit，简称为RS)报文后，无论备路由器做出多少时间延迟回复单播路由公告(Router Advertise，简称为RA)报文，实际上都无法阻止用户发现备路由器作为网关，进而获取到备路由器的前缀地址和网关，如果用户获取了多个网关，用户则生成多条同类型同优先级的默认路由。由此看来，当前的IPoEv6冷备组网中，即无法保证用户从主路由器上线，又可能将用户上行流量引向备路由器。
动态主机配置协议版本6(Dynamic Host Configuration Protocol v6，简称为DHCPv6)有状态获取地址时，虽然可以通过控制备路由器延时DHCPv6协议报文，让用户获取主路由器的地址，但是在DHCPv6有状态获取地址之前用户主动发送RS报文时，还是会发生和无状态获取地址时一样的问题：即用户发现了备路由器作为网关。
因此，相关技术中双机冷备组网中用户获取的地址带有不确定性的问题。

在本实施例中提供了一种运行于路由器的报文处理方法，图2是根据本发明实施例的报文处理方法的流程图一，如图2所示，该流程包括如下步骤：
步骤S202，主路由器接收到来自用户的请求报文，其中，请求报文需要进行回复；
步骤S204，主路由器根据请求报文向用户回复报文；
步骤S206，向备路由器告知用户的信息，其中，该用户的信息用于通知备路由器不对来自该用户的该请求报文进行回复，主路由器和备路由器为主备关系。
通过上述步骤，主路由器根据用于的请求报文向用户回复报文，并通知备路由器不对来自该用户的该请求报文进行回复，用户获取的地址为主路由器的地址，通过主路由器与备用路由器之间的上述交互，解决了相关技术中双机冷备组网中用户获取的地址带有不确定性的问题，提高了用户获取路由器地址的有效性。
可选地，上述步骤中涉及的主路由器和备用路由器可以仅是主备关系区别，两者在结构上可以相同或者不同，在必要时，主路由器与备用路由器可以进行相互转换，某一用户的主路由器可以为其他用户的备路由器。
可选地，步骤S204和步骤S206的执行顺序是可以互换的，即可以先执行步骤S206，然后再执行S204。
可选地，在步骤S206中，主路由器可以采用多种方式向备路由器告知用户的信息，例如，主路由器可以在闲时向备用路由器告知用户的信息，又例如，主路由器可以在预定时长内向备路由器告知该用户的信息，其中，上述预定时长为备路由器延迟回复请求报文的时长。
通过本发明实施例的上述技术方案，主路由器可以在备路由器延迟回复请求报文的时长内向备路由器告知该用户的信息，保证了备路由器在延迟回复请求报文的时长 内收到主路由器告知的用户信息，保证了用户获取路由器地址的效率。
可选地，上述预定时长可以大于主路由器向用户回复报文用的时间。即，备路由器延迟回复用户请求报文的时长可以大于主路由器向用户回复报文用的时间。
通过本发明实施例的上述技术方案，将备路由器延迟回复用户请求报文的时长大于主路由器向用户回复报文用的时间，可以保证在备用路由器延迟回复用户请求报文的时间到达前，主路由器向用户回复报文，保证了用户可以获取到主路由器的地址，提高了用户获取路由器地址的准确性。
可选地，上述请求报文可以包括以下至少之一：路由请求RS报文、DHCPv6报文，上述回复的报文可以包括以下至少之一：路由通告RA报文、DHCPv6报文。
在本实施例中还提供了一种运行于路由器的报文处理方法，图3是根据本发明实施例的报文处理方法的流程图二，如图3所示，该流程包括如下步骤：
步骤S302，备路由器接收到用户的请求报文，其中，请求报文需要进行回复；
步骤S304，备路由器判断是否从主路由器接收到用户的信息，其中，主路由器和备路由器为主备关系；
步骤S306，备路由器在判断结果为接收到用户的信息的情况下，不对用户的该请求报文进行回复。
通过上述步骤，备路由器备判断是否从主路由器接收到用户的信息，在收到用户的信息的情况下不对用户的该请求报文进行回复，通过主路由器与备路由器之间的上述交互，解决了相关技术中双机冷备组网中用户获取的地址带有不确定性的问题，提高了用户获取路由器地址的有效性。
可选地，上述步骤中涉及的主路由器和备用路由器可以仅是主备关系区别，两者在结构上可以相同或者不同，在必要时，主路由器与备用路由器可以进行相互转换，某一用户的主路由器可以为其他用户的备路由器。
可选地，在步骤S304中，备路由器可以采用多种方式判断是否从主路由器接收到用户的信息，例如，备路由器可以在接收到用户的请求报文时立即判断是否接收到用户的信息，又例如，备路由器可以根据在预定时长内是否收到用户的信息，判断是否从主路由器接收到用户的信息。与立即判断是否接收到用户的信息的方式相比，根据在预定时间内是否收到用户的信息判断是否从主路由器接收到用户的信息，为主处理器接收用户的请求报文以及发送用户的信息预留了时间，提高了用户获取路由器信 息的准确性。
通过本发明实施例的上述技术方案，备路由器根据在预定时间内是否收到用户的信息判断是否从主路由器接收到用户的信息，为主处理器接收用户的请求报文以及发送用户的信息预留了时间，提高了用户获取路由器信息的准确性。
可选地，备路由器在预定时长内未收到用户的信息的情况下，可以采用多种方式进行处理，例如，备用路由器可以与主处理器交互，确定主处理器的状态，根据主处理器的状态确定是否对用户的请求报文进行回复。又例如，备路由器可以在预定时长内未收到用户的信息的情况下，对用户的请求报文进行回复。
通过本发明实施例的上述技术方案，备路由器在预定时长内未收到用户的信息的情况下，对用户的请求报文进行回复，提高了用户获取路由器地址的效率。
可选地，上述预定时长可以大于主路由器向用户回复报文用的时间。即，备路由器延迟回复用户请求报文的时长可以大于主路由器向用户回复报文用的时间。
通过本发明实施例的上述技术方案，将备路由器延迟回复用户请求报文的时长大于主路由器向用户回复报文用的时间，可以保证在备用路由器延迟回复用户请求报文的时间到达前，主路由器向用户回复报文，保证了用户可以获取到主路由器的地址，提高了用户获取路由器地址的准确性。
可选地，上述请求报文可以包括以下至少之一：路由请求RS报文、DHCPv6报文，上述回复的报文可以包括以下至少之一：路由通告RA报文、DHCPv6报文。
基于上述实施例及可选实施方式，为说明方案的整个流程交互，在本优选实施例中，分别针对主路由器可用以及主处理器宕机两种情况进行说明。
在双机冷备的组网中，备路由器做RA报文和DHCPv6报文延时响应，当主备路由器同时收到组播RS之后，在备路由器延时响应的时间内，主路由器正常给用户回复单播RA报文或DHCPv6报文的同时，需要将回复RA目的用户MAC(作用同上述用户的信息)告诉备路由器，备路由器记录此用户MAC，进而备路由器对此MAC用户的RS或者DHCPv6报文不做回应，合理时间(确保用户从主路由器成功接入)(作用同上述预定时长)后释放此抑制。释放抑制后，如果再收到此MAC用户的RS或者DHCPv6报文，重复上述流程。备路由器收到用户的RS或者DHCPv6报文后，如果在延时响应报文的时间内未收到其他路由器(如主路由器)通告此用户的MAC，延时时间到后(此时认为主路由器宕机)，备路由器对该用户报文做响应， 提供接入，用户从备路由器获取地址和网关。为保证用户只能获取到主路由器的IPv6前缀地址或DHCPv6地址，并以主路由器作为网关，备路由器延时响应报文的时间设置为大于主路由器通告用户MAC所需的时间。
下面针对主路由器可用以及主处理器宕机两种情况进行分别进行说明。
图4是根据本发明优选实施例的主路由器正常的报文处理示意图，如图4所示，初始配置R1为宽带远程服务器(Broadband Remote Access Server，简称为BRAS)主机(主路由器)，R2为BRAS备机(备路由器)，备机配置响应延迟。在R1可用的情况下：
当用户开机时首先发送组播RS报文(无状态接入)或首先发送组播RS后再发送DHCPv6的Solicit发现报文(有状态接入)，因为R2为备路由器延时响应报文，所以R1优先R2处理RS报文和Solicit报文，当R1为无状态接入时，用户会根据R1发送的RA报文生成IPv6前缀地址和网关；当R1提供有状态接入时，用户会根据R1发送的RA报文生成网关，并获取R1发送的Advertise报文分配的DHCPv6地址上线。所以不管R1是无状态接入还是有状态接入，此时用户都是从R1获取IPv6地址和网关。
在R1给用户发送的RA报文的同时复制一份RA内容信息，报文源MAC为用户的MAC，目的MAC为R2的MAC(R2的MAC可以预先在R1上配置)，从而R1将RA发送到R2，R2收到该RA报文时做处理，解析出报文的源MAC后，将此MAC做接入抑制，对该MAC的RS报文和DHCPv6报文都不做回应。合理时间(用户已经从R1成功接入)后释放该抑制。释放抑制后，如果再收到此MAC用户的RS或者DHCPv6报文，重复上述响应抑制流程。保证了R1可用情况下用户只能从R1获取IPv6地址和网关，而不会从R2获取IPv6地址和网关。避免了双机冷备组网中用户获取多网关的情况。
图5是根据本发明优选实施例的主路由器宕机的报文处理示意图，如图5所示，配置R1为BRAS主机，R2为BRAS备机，备机配置响应延迟。在主机R1宕机的情况下：
当用户开机时首先发送组播RS报文(无状态接入)或首先发送组播RS后再发送DHCPv6的Solicit报文(有状态接入)，R1宕机不响应用户报文，R2在延时响应时间内也没有收到R1单播通告的用户MAC的RA报文，所以R2延时响应时间到 后响应用户报文，当R2为无状态接入时，用户会根据R2发送的RA报文生成IPv6前缀地址和网关；当R2提供有状态接入时，用户会根据R2发送的RA报文生成网关，并获取R2发送的Advertise报文分配的DHCPv6地址上线。所以不管R2是无状态接入还是有状态接入，此时用户只能从R2获取IPv6地址和网关。
通过本发明实施例的上述技术方案，保证了在主处理器正常的情况下，用户只能获取到主路由器的IPv6前缀地址或DHCPv6地址，并以主路由器作为网关，而在主处理器宕机等主处理器异常的情况下，用户也能获取到备路由器的IPv6前缀地址或DHCPv6地址，并以备路由器作为网关，提高了用户获取路由器地址和网关的可靠性和准确性。
可选地，在网络中包含多个备用路由器的情况下，可以对不同的备用路由器设置不同的释放时间，使得在主处理器宕机的情况下，首先由释放时间最短的备路由器进行处理，释放时间最短的备用路由器正常的情况下，向其余的备路由器通告用户MAC地址，使得其他备路由器预定时间内部处理该MAC的RS报文和DHCPv6报文都不做回应。各备路由器释放时间的设置类似与上述实施例中的备路由器的设置方式，这里不做赘述。
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，本发明的技术方案本质上或者说对现有技术做出贡献的部分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，包括若干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)执行本发明各个实施例所述的方法。
