Description

流量转发方法及装置 技术领域
本文涉及但不限于网络通信领域，尤指一种流量转发方法及装置。
背景技术
随着网络通信技术的发展，目前VRRP(Virtual Router Redundancy Protocol，虚拟路由器冗余备份协议)将局域网内的一组路由器划分在一起，称为一个备份组。备份组由一个Master路由器(主用设备)和多个Backup路由器(备用设备)组成，功能上相当于一台虚拟路由器。在主用设备转发流量时，通过存储的VRRP备份组地址信息将流量转发出去，而备用设备没有存储VRRP备份组地址信息，因此不能转发流量。但是在主用设备发生故障时，备用设备通过感知主用设备的故障，切换为主用设备从而进行流量的转发。但是，目前存在的问题是，备用设备切换为主用设备时，由于还没存储VRRP备份组地址信息，如果这个时候流量已经传送到该主用设备，由于主用设备无法转发该流量，而产生流量丢包的情况。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本发明实施例提出一种流量转发方法及装置，能够在备用设备切换为主用设备时，减少由于无法转发流量而导致流量丢包的情况。
本发明实施例提供的一种流量转发方法，所述流量转发方法包括以下步骤：在路由设备的运行状态为虚拟路由器冗余备份协议VRRP备份组中的备用设备时，所述路由设备存储所述VRRP备份组的地址信息；
若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则所述路由设备接收终端发送的流量；
若所述流量的目的地址信息与所述路由设备存储的所述地址信息一致，则所述路由设备转发所述流量。
可选地，所述若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则所述路由设备接收终端发送的流量的步骤包括：
若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则所述路由设备将运行状态由备用设备切换为主用设备；
当所述路由设备将运行状态由备用设备切换为主用设备时，所述路由设备接收终端发送的流量。
可选地，所述检测到所述VRRP备份组中的主用设备发生故障包括：
所述路由设备接收所述主用设备发送的VRRP报文；
若在预设时间间隔内未接收到所述主用设备发送的所述VRRP报文，则所述路由设备确定所述主用设备发生故障。
可选地，当所述路由设备的设备优先级为所述主用设备的下一级设备时，或者所述路由设备预存有所述主用设备与所述路由设备之间的关联关系时，所述路由设备为主用设备关联的备用设备。
本发明实施例还提出一种流量转发装置，所述流量转发装置包括：
存储模块，设置为在路由设备的运行状态为虚拟路由器冗余备份协议VRRP备份组中的备用设备时，存储所述VRRP备份组的地址信息；
第一接收模块，设置为若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则接收终端发送的流量；转发模块，设置为若所述流量的目的地址信息与所述路由设备存储的所述地址信息一致，则转发所述流量。
可选地，所述第一接收模块包括：
切换单元，设置为若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则将运行状态由备用设备切换为主用设备；
接收单元，设置为当所述路由设备将运行状态由备用设备切换为主用设备 时，接收终端发送的流量。
可选地，所述流量转发装置还包括：
第二接收模块，设置为接收所述主用设备发送的VRRP报文；
确定模块，设置为若在预设时间间隔内未接收到所述主用设备发送的所述VRRP报文，则确定所述主用设备发生故障。
可选地，当所述路由设备的设备优先级为所述主用设备的下一级设备时，或者所述路由设备预存有所述主用设备与所述路由设备之间的关联关系时，所述路由设备为主用设备关联的备用设备。
本发明实施例提出的流量转发方法及装置，在路由设备的运行状态为VRRP备份组中的备用设备时，所述路由设备存储所述VRRP备份组的地址信息，然后若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，接收终端发送的流量，并在所述流量的目的地址信息与所述路由设备存储的所述地址信息一致，直接转发所述流量，而不是在路由设备将运行状态由备用设备切换为主用设备时，要先存储所述VRRP备份组的地址信息，然后才能进行流量的转发，导致无法转发该流量而产生流量丢包的情况，本方案通过事先存储的地址信息直接转发接收到的流量，减小了流量转发过程中流量丢包的情况。

本发明的实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种流量转发方法。
参照图1，图1为本发明流量转发方法第一实施例的流程示意图。
本实施例提出一种流量转发方法，所述流量转发方法包括：
步骤S10，在路由设备的运行状态为虚拟路由器冗余备份协议VRRP备份组中的备用设备时，所述路由设备存储所述VRRP备份组的地址信息；
在虚拟路由器冗余备份协议VRRP备份组中，包括一个主用设备和一个或多个备用设备，本实施例可选包括多个备用设备。在主用设备和备用设备竞选成功后，主用设备和备用设备对应的路由设备都会存储所述VRRP备份组的地址信息，即在路由设备的运行状态为虚拟路由器冗余备份协议VRRP备份组中的备用设备时，所述路由设备存储所述VRRP备份组的地址信息，所述地址信息包括虚拟物理地址或虚拟互联网协议(IP，Internet Protocol)地址，本实施例可选所述地址信息包括虚拟物理地址(Media Access Control，MAC)，所述路由设备存储所述VRRP备份组的地址信息的方式包括：所述路由设备先通过其控制面发送VRRP报文对应的虚拟物理地址给转发面，然后通过转发面存储所述虚拟物理地址，实现了在VRRP备份组中的主用设备正常发送VRRP报文时，即所述主用设备处于正常工作状态下，每一个备用设备对应的路由设备事先存储了所述VRRP备份组中的虚拟物理地址。
也就是说，备用设备竞选成功后，自身的运行状态就是备用设备。
其中，VRRP报文由主用设备发送给备用设备(即路由设备)的控制面。
其中，VRRP报文是主用设备用来告知其他设备自身仍处于工作状态，其他设备一直侦听VRRP报文，一段时间收不到VRRP报文，就认为主用设备发生故障。
步骤S20，若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则所述路由设备接收终端发送的流量；
在本实施例中，所述步骤S20的实施方式包括：
1)方式一、在检测到所述VRRP备份组中的主用设备发生故障时，所述路由设备基于预设的设备优先级先确定所述主用设备是否为上一级设备，所述上一级是表示两个设备之间是设备优先级相邻的关系，当关联的主用设备为所述路由设备的上一级设备时，换句话说，也就是当所述路由设备的设备优先级为所述主用设备的下一级设备时，即可确定所述路由设备为主用设备关联的备用设备，此时，所述路由设备接收终端发送的流量。
2)方式二、在检测到所述VRRP备份组中的主用设备发生故障时，所述路由设备先确定是否预存有所述主用设备与所述路由设备之间的关联关系，当所述路由设备预存有所述主用设备与所述路由设备之间的关联关系时，即可确定所述路由设备为主用设备关联的备用设备，此时，所述路由设备接收终端发送的流量。在本实施方式中，所述主用设备和路由设备事先连接心跳线，即所述主用设备与所述路由设备基于连接的心跳线建立有关联关系，在所述主用设备发生故障时，与所述主用设备连接心跳线的路由设备即可感知所述主用设备的故障，并接收终端发送的流量。
步骤S30，若所述流量的目的地址信息与所述路由设备存储的所述地址信息一致，则所述路由设备转发所述流量。
在本实施例中，在所述路由设备接收到终端发送的流量时，先确定所述接收到的流量对应的目的地址信息是否与存储的地址信息相匹配，若匹配，可直接根据存储的地址信息转发所述流量，所述转发所述流量的方式包括路由设备查询预存的转发表，以获取所述流量的出端口，然后根据获取的所述出端口转发所述流量，通过预存的地址信息直接转发流量，提高了流量转发的速度，同时，不需要在接收到终端发送的流量时，要先存储所述VRRP备份组的地址信息，然后等到VRRP备份组的地址信息存储后，再进行流量的转发，这个等待的过程，由于终端可能一直都在发送流量，而此时所述路由设备无法进行流量的转发，而导致所述流量的丢包。
本实施例提出的流量转发方法，在路由设备的运行状态为VRRP备份组中的备用设备时，所述路由设备存储所述VRRP备份组的地址信息，然后若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主 用设备关联的备用设备时，接收终端发送的流量，并在所述流量的目的地址信息与所述路由设备存储的所述地址信息一致，直接转发所述流量，而不是在路由设备将运行状态由备用设备切换为主用设备时，要先存储所述VRRP备份组的地址信息，然后才能进行流量的转发，导致无法转发该流量而产生流量丢包的情况，本方案通过事先存储的地址信息直接转发接收到的流量，减小了流量转发过程中流量丢包的情况。
可选地，为了增加流量转发的灵活性，基于第一实施例提出本发明流量转发方法的第二实施例，在本实施例中，参照图2，所述步骤S20包括：
步骤S21，若检测到所述VRRP备份组中的主用设备发生故障，且所述路由设备为所述主用设备关联的备用设备时，则所述路由设备将运行状态由备用设备切换为主用设备；
步骤S22，当所述路由设备将运行状态由备用设备切换为主用设备时，所述路由设备接收终端发送的流量。
在本实施例中，所述路由设备在检测到所述VRRP备份组中的主用设备发生故障时，所述路由设备基于预设的设备优先级先确定所述主用设备是否为上一级设备，若所述主用设备为所述路由设备的上一级设备，所述路由设备直接将运行状态由备用设备切换为主用设备，并且所述路由设备接收终端发送的流量。
可选地，若所述主用设备不是所述路由设备的上一级设备，则所述路由设备保持不变。在本实施方式中，所述设备优先级包括所述VRRP备份组中预设的切换优先级，即在所述VRRP备份组中会事先对每一个备用设备对应的路由设备设定切换优先级，当所述主用设备发生故障，需要所述主用设备下一级的路由设备切换为主用设备时，所述主用设备下一级的路由设备基于预设的设备优先级即可直接切换为主用设备，而此时，比所述路由设备的设备优先级更低的其它路由设备可进入休眠状态，同理，在所述路由设备将运行状态由备用设备切换为主用设备时，所述路由设备的下一级的路由设备进行工作状态，而其它级别更低的路由设备相当于进入休眠状态。
可选地，为提高所述路由设切换为主用设备的灵活性，所述路由设备还可在检测到所述VRRP备份组中的主用设备发生故障时，先确定是否预存有 所述主用设备与所述路由设备之间的关联关系，若预存有所述主用设备与所述路由设备之间的关联关系，所述路由设备可以直接将运行状态由备用设备切换为主用设备。即所述主用设备和路由设备事先连接心跳线，基于连接的所述心跳线建立关联关系，并在所述主用设备发生故障时，与所述主用设备连接心跳线的路由设备即可感知所述主用设备的故障，并将运行状态由备用设备直接切换为主用设备。
可选地，为了增加流量转发的灵活性，基于第一实施例提出本发明流量转发方法的第三实施例，在本实施例中，参照图3，所述步骤S20中，检测到VRRP备份组中的主用设备发生故障包括：
步骤S40，所述路由设备接收所述主用设备发送的VRRP报文；
步骤S50，若在预设时间间隔内未接收到所述主用设备发送的所述VRRP报文，则所述路由设备确定所述主用设备发生故障。
在本实施例中，在所述VRRP备份组中的主用设备实时发送VRRP报文的过程中，相应地，所述路由设备实时接收所述主用设备发送的VRRP报文，此时所述主用设备实时发送VRRP报文，说明所述主用设备处于正常工作模式，如所述主用设备每个1秒发送一次VRRP报文，而当所述路由设备在预设时间间隔内未接收到所述VRRP报文，如间隔3秒都没接收到所述主用设备发送的所述VRRP报文，则所述路由设备可确定所述主用设备发生故障，并可直接接收终端发送的流量。
