Description

一种数据包处理装置及方法 技术领域
本发明涉及通信技术领域，尤其涉及一种数据包处理装置及方法。
背景技术
在固定或移动宽带接入领域及数据中心应用中，会存在很多基于4层到7层的增值业务处理，包括：防病毒、防火墙、应用缓存和加速、NAT地址转换等。通常如图1所示，在固定或移动用户接入设备后面串接提供上述增值业务处理功能的增值业务处理设备，将这些增值业务处理设备及相关的交换机和控制设备组成的网络，称为“增值业务处理网络”。
在实际应用中，可能部分用户的业务流需要进行NAT地址转换；仅视频或Web访问的业务流才需要应用缓存和加速。但在图1所示网络架构中，所有的业务流都需要流经串接的多个增值业务处理设备，不管这些业务流是否需要进行相应的增值业务处理。此方式对增值业务处理设备的处理容量要求大，导致不必要的网络设备投资；同时，也会增加网络中的故障点，某个增值业务处理设备故障，会导致整体业务流中断和故障。
为解决上述问题，业界提出了“业务链”的概念，业务链就是某个业务流所需经过的增值业务序列以及经过增值业务序列的顺序。比如：(防病毒、防火墙、NAT地址转换)、(应用缓存和加速、防火墙、NAT地址转换)和(防火墙、NAT地址转换)分别属于不同的业务链，不同业务链的业务流只需流经相应的服务节点(即：增值业务处理设备)即可。
采用业务链技术的一个典型的增值业务处理网络如图2所示，包括：控制器，比如：软件定义网络(Software Defined Network，SDN)、分类器、交换机(可包括一个或多个交换机)和增值业务(Value Added Service，VAS)处理器等，其中VAS处理器就是前面所述增值业务处理设备。
每个类型的VAS处理器中包括一个或多个VAS实例：实例1至实例N， N为正整数。在实际的业务流传输过程中，同一个业务链对应多种业务路径。
比如：业务链是VAS类型1+VAS类型2+VAS类型3，但实际的业务路径包括但不限于下述几种：
VAS类型1-实例1+VAS类型2-实例2+VAS类型3-实例1；
VAS类型1-实例2+VAS类型2-实例1+VAS类型3-实例1；
VAS类型1-实例1+VAS类型2-实例2+VAS类型3-实例3。
目前在确定业务路径时，常用的做法是随机选择VAS类型中的实例，这样的做法可能导致某个实例的负荷较大，而其他实例的负荷较小，各实例之间负荷不均。

数据包处理装置301和数据包路由装置302可位于同一设备或不同设备中，比如位于同一交换机中。可选地，数据包处理装置301和数据包路由装置302中预先配置了该增值业务处理网络的网络拓扑信息，包括但不限于该增值业务处理网络中包括哪些交换机，每个交换机的地址和端口号，每个交换机连接的VAS类型，每个VAS类型中各VAS实例的地址和端口号等。可选地，数据包处理装置301中还预先配置了该增值业务处理网络中的各业务链的业务链的信息，比如：图3中业务链A经过VAS类型1和VAS类型3。
数据包处理装置301在收到第一数据包后，从第一数据包中可获取业务链的信息，根据该业务链的信息确定第一数据包要经过的业务链。由于数据包处理装置301中预先配置了该增值业务处理网络的网络拓扑信息，则数据 包处理装置301可获取该业务链上各VAS类型对应的各VAS实例的负荷情况、状态信息等，数据包处理装置301可根据获取的业务链上各VAS类型对应的各VAS实例的负荷情况和/或状态信息，确定在该增值业务处理网络中传输第一数据包时，第一数据包具体经过的VAS实例。
比如：设第一数据包经过该增值业务处理网络中的业务链A，则数据包处理装置301在收到分类器303发送的第一数据包后，首先获取第一数据包中的业务链的信息，根据该业务链的信息确定第一数据包经过业务链A。数据包处理装置301获取业务链A上的VAS类型1中各VAS实例的负荷情况，以及VAS类型3中各VAS实例的负荷情况。若VAS类型1中的实例1的负荷比实例2的负荷轻，VAS类型3中的实例2是四个实例中负荷最轻的实例，则数据包处理装置301确定第一数据包经过的业务路径为：
VAS类型1-实例1+VAS类型3-实例2。
再比如：数据包处理装置301获取业务链A上的VAS类型1中各VAS实例的状态信息，以及VAS类型3中各VAS实例的状态信息。若VAS类型1中的实例1的状态信息指示实例1可用，实例2的状态信息指示实例2不可用；VAS类型3中的四个实例均可用，但实例2是四个实例中负荷最轻的实例，则数据包处理装置301确定第一数据包经过的业务路径仍为：
VAS类型1-实例1+VAS类型3-实例2。
数据包处理装置301将用于标识上述业务路径的业务路径标识置于第一数据包中，将第一数据包发给数据包路由装置302。
比如：可预先将所有可能的业务路径的信息配置在数据包处理装置301和数据包路由装置302中，并对所有可能的业务路径进行编号，比如：
P1：VAS类型1-实例1+VAS类型3-实例1；
P2：VAS类型1-实例1+VAS类型3-实例2；
P3：VAS类型1-实例1+VAS类型3-实例3；
P4：VAS类型1-实例1+VAS类型3-实例4；
P5：VAS类型1-实例2+VAS类型3-实例1；
……
当数据包处理装置301将业务路径标识P2发给数据包路由装置302时，数据包路由装置302即可根据P2，确定对应的业务路径为VAS类型1-实例1+VAS类型3-实例2。
再比如：业务路径的标识为字符串，比如：“1-1:3-2”，即表示业务路径VAS类型1-实例1+VAS类型3-实例2。
业务路径的标识的实现方式有很多，只要能唯一标识业务路径即可，因此这里不再一一列举。
数据包路由装置302在确定业务路径后，即可根据该业务路径对数据包处理装置301进行路由。比如：对于上面的业务路径：VAS类型1-实例1+VAS类型3-实例2，首先将第一数据包通过交换机发给VAS类型1的实例1处理，之后发给VAS类型3的实例2处理。
可选地，数据包处理装置301还可根据业务链上各VAS类型对应的各VAS实例的负荷情况，以及第一数据包所属用户的用户标识，基于同一用户的同一业务流的数据包经过相同的VAS类型时选择同一VAS实例的原则，确定第一数据包的业务路径。
比如：第一数据包属于用户M的业务流1，在第一数据包之前，数据包处理装置301还接收过用户M的业务流1的其他数据包，若数据包处理装置301在确定该其他数据包的业务路径为：VAS类型1-实例1+VAS类型3-实例3，则基于同一用户的同一业务流的数据包经过相同的VAS类型时选择同一VAS实例的原则，数据包处理装置301在确定第一数据包的业务路径时，还选择业务路径：VAS类型1-实例1+VAS类型3-实例3。
可选地，数据包处理装置301获取业务链上各VAS类型对应的各VAS实例的负荷情况、状态信息时，可周期性获取，当收到第一数据包后，根据最近一次获取的符合情况和/或状态信息，确定业务路径；或者
数据包处理装置301可在收到第一数据包后，再获取业务链上各VAS类型对应的各VAS实例的负荷情况、状态信息，并根据获取的负荷情况和/或状 态信息，确定业务路径。
可选地，第一数据包为第一数据包所属业务流的首包，数据包处理装置301在确定第一数据包经过的业务路径之后，记录第一数据包所属业务流的业务流标识和该业务路径的业务路径标识的对应关系。
业务流的标识可为业务流的五元组或业务流对应的应用标识。其中，五元组包括：源IP地址、目的IP地址、协议号、源端口号、目的端口号。
在数据包处理装置301接收第二数据包，若第二数据包为第一数据包所属业务流的非首包，则数据包处理装置301不再重新为第二数据包确定业务路径，而是直接将处理第一数据包时，确定的第一数据包经过的业务路径的业务路径标识置于第二数据包中，将携带该业务路径标识的第二数据包发往数据包路由装置302，数据包路由装置302根据该业务路径标识所标识的业务路径对第二数据包进行路由，即对属于同一业务流的不同数据包根据相同的业务路径进行路由，减轻了数据包处理装置301的处理负荷。
下面，通过一个具体的实施例一，说明本发明实施例提供的增值业务处理网络中，分类器303、数据包处理装置301和数据包路由装置302对数据包的处理过程。
【实施例一】
如图4所示，实施例一包括如下步骤：
S401：分类器303配置预定义策略规则，或接收来自其它逻辑功能的策略规则，比如：来自策略与计费规则功能(Policy and Charging Rules Function，PCRF)单元的策略规则；或者，分类器还接受PCRF单元下发的策略规则，即：分类器根据预定义策略规则以及PCRF单元下发的策略规则，生成业务链。
S402：根据步骤S401中的策略规则(预定义策略规则和/或PCRF单元下发的策略规则)，对不同的业务流生成不同的业务链的业务链的信息；
S403：接收数据包；
S404：分类器303将业务链的信息置于数据包中，将数据包发给数据包 处理装置301，可选地，数据包中还可包括用户标识和/或业务流标识等；
S405：数据包处理装置301根据数据包中的业务链的信息，按照同一个用户的同一种业务流须经过相同的VAS实例的要求，以及根据VAS实例之间的负荷均衡策略等，确定数据包经过的业务链上的每个VAS类型中的VAS实例，以确定该数据包经过的业务路径；并记录业务流的业务流标识与业务路径的对应关系，比如：记录业务流的五元组与业务路径的对应关系，当数据包为该业务流为非首包时，则直接选之前为该业务流上的其他数据包确定的业务路径；
S406：数据包处理装置301向数据包路由装置302发送数据包，数据包中包括为该数据包确定的业务路径的业务路径标识；
S407：数据包路由装置302记录该业务流标识与物理链的对应关系，确定该数据包中的业务路径标识所标识的业务路径中的第一个VAS实例，获取该实例的MAC地址等，如果是最后一跳，则根据业务链中配置的出口策略执行处理，比如：直接将数据包发送至互联网(INTERNET)。
数据包路由装置302剥离数据包中的业务路径标识，封装MAC地址，将处理后的数据包发送给指定的VAS实例；
S408：数据包路由装置302将数据包发送至第一个VAS实例；
S409：第一个VAS实例将数据包处理完后，将数据包返回数据包路由装置302；
S410：数据包路由装置302根据记录的业务流标识与业务路径的对应关系，对数据包进行路由；
S411：数据包路由装置302将数据包发送至业务路径中的下一个VAS实例；
如果下一个VAS实例不属于当前的增值业务处理网络，则数据包路由装置302将数据包发送到数据包处理装置301,数据包处理装置301根据下一跳的VAS实例，确定数据包下一跳的其他增值业务处理网络中的数据包处理装置301，然后将数据包路由到该其他增值业务处理网络的数据包处理装置301 上，由该数据包处理装置301按照本实施例的步骤重复执行。
