技术领域
本申请涉及网络技术领域，特别是涉及一种报文处理方法、装置和计算机可读存储介质。
背景技术
随着IPv4地址的枯竭，IPv6地址在当前公网中已投入使用，支持IPv6报文的转发已经是网络设备的基本要求。在本领域一些情形中，IPv6报文是通过IPv6转IPv6NAT(Network Address Translation，网络地址转换)方式转换地址进行地址汇聚，以使得下行报文可以回到上行同一个设备，但运营商不希望再对IPv6地址进行NAT转换，因为这种转换会导致性能降低，打破了互联网本身的"互联"特性，使得一部分IP地址不再双向可达。然而，没有NAT转换会导致从一个设备上行出去的IPv6报文地址是离散的，所以其下行报文无法回到上行同一个设备。因此，如何无需经过NAT转换而实现下行报文回到上行同一个设备成为亟待解决的问题。

随着IPv4地址的枯竭，IPv6地址在当前公网中已投入使用，支持IPv6报文的转发已经是网络设备的基本要求。在本领域一些情形中，IPv6报文是通过IPv6转IPv6NAT方式转换地址进行地址汇聚，以使得下行报文可以回到上行同一个设备，但运营商不希望再对IPv6地址进行NAT转换，因为这种转换会导致性能降低，打破了互联网本身的"互联"特性，使得一部分IP地址不再双向可达。然而，没有NAT转换会导致从一个设备上行出去的IPv6报文地址是离散的，所以其下行报文无法回到上行同一个设备。因此，如何无需经过NAT转换而实现下行报文回到上行同一个设备成为亟待解决的问题。
本申请实施例提供了一种报文处理方法、装置和计算机可读存储介质,通过报文发送 网元先获取关联规则，关联规则用于将由IPv6地址池划分得到的多个地址段与多个处理机关联；然后，报文发送网元获取待发送报文及其源IP地址，并根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。此外，多个处理机同样获取关联规则，而目的处理机获取待发送报文及其源IP地址，目的处理机根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。基于此，接收下行报文时，路由器会将下行报文按照边界网关协议BGP回到上行同一个处理机。因此，本实施例提供的方案通过报文发送网元以及处理机进行地址汇聚，从而无需经过NAT转换即可实现下行报文回到上行同一个设备。同时，由于避免了NAT转换，网络性能得到提升。
如图1所示，图1是本申请一个实施例提供的一种报文处理方法的流程图。该报文处理方法应用于报文发送网元，其包括但不限于如下步骤：
步骤101，获取关联规则，关联规则用于将由lPv6地址池划分得到的多个地址段与多个处理机关联。
步骤102，获取待发送报文及其源IP地址。
步骤103，根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。
在一实施例中，报文发送网元获取关联规则，其中，关联规则用于将由lPv6地址池划分得到的多个地址段与多个处理机关联，然后，报文发送网元获取待发送报文及其源IP地址，再根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。由于报文发送网元预先获取关联规则，因此，报文发送网元可以根据关联规则确定源lP地址所在地址段对应的目的处理机，从而将待发送报文发送至目的处理机。在本实施例中，利用关联规则将由lPv6地址池划分得到的多个地址段与多个处理机关联起来，使得处于同一地址段的IPv6报文地址可以聚合到同一个处理机，以避免上行出去的IPv6报文地址是离散的。基于此，通过报文发送网元的聚合进行地址汇聚，从而无需经过NAT转换即可实现下行报文回到上行同一个设备。同时，由于避免了NAT转换，网络性能得到提升。
在一实施例中，步骤101可以包括但不限于如下子步骤：
获取关联规则，关联规则用于将由IPv6地址池均衡划分得到的多个地址段与多个处理机关联，其中，每个地池段的IP地址个数为2 n*1024，N为自然数。
在关联规则中，对用户终端IPv6地址池进行均衡划分，使得每个地池段的地址个数为2 n*1024，其中，N为自然数。即每一个地址段的IP地址个数可以取值包括但不限于1024、2048、4096、8192。例如，下表A1是对地址池1:2:3:0/48按照8192个地址为一个地址段进行划分举例。
前缀 前缀长度 划分段序号 划分地址后段
1:2:3:0 48 1 1:2:3:0/51
1:2:3:0 48 2 1:2:3:2000/51
1:2:3:0 48 3 1:2:3:4000/51
1:2:3:0 48 4 1:2:3:5FFF/51
1:2:3:0 48 5 1:2:3:7FFF/51
1:2:3:0 48 6 1:2:3:9FFF/51
1:2:3:0 48 7 1:2:3:BFFF/51
1:2:3:0 48 8 1:2:3:DFFF/51
在一实施例中，步骤101可以包括但不限于如下子步骤：
获取关联规则，关联规则用于将由lPv6地址池划分得到的多个地址段依次循环与多个处理机逐一关联。在本实施例中，将多个地址段均摊到各个处理机逐一关联，使得处于同一地址段的IPv6报文地址可以聚合到同一个处理机，以避免上行出去的IPv6报文地址是离散的。
例如，如下表B1，下一跳网元有3个处理机，分别为处理机1、处理机2和处理机3。其中，NextHop序号是处理机的序号，NextHopTunnel是处理机的隧道地址，NextHopIPv6是处理机的IPv6接口地址，分别用于发送和接收IPv6报文。
NextHop序号 NextHopTunnel NextHopIPv6
1 1.1.1.1 2001:0:1:1
2 1.1.2.2 2001:0:2:2
3 1.1.3.3 2001:0:3:3
把表A1中划分的8个地址段依次循环与表B1的3个处理机关联。例如，下表中，处理机1存放了划分段序号分别为1、4、7的三个地址段，处理机2存放了划分段序号分别为2、5、8的三个地址段，处理机3存放了划分段序号分别为3、6的两个地址段。这样存放的好处是多个地址段可以被均摊到各个处理机。
NextHop序号 地址段列1 地址段列2 地址段列3
1 1 4 7
2 2 5 8
3 3 6  
在一实施例中，步骤103可以包括但不限于如下子步骤：
将关联规则同步给多个处理机，根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。
在本实施例中，处理机自身可以有预设的关联规则，因此，为了让处理机同步更新关联规则，需要将多个地址段与多个处理机地址逐一对应的关联规则同步给下一跳网元的处理机。然后，报文发送网元根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。基于此，报文发送网元按照地池段发送报文给下一跳网元实现负荷分担。需要指出的是，将关联规则同步给多个处理机后，当获取到打开负荷分担指令，处理机更新关联规则进行报文转发，否则处理机按照原有的关联规则进行报文转发。
如图2所示，图2是本申请一个实施例提供的一种报文处理方法的流程图。该报文处理方法应用于处理机，其包括但不限于如下步骤：
步骤201，获取关联规则，关联规则用于将由lPv6地址池划分得到的多个地址段与处 理机关联。
步骤202，获取待发送报文及其源IP地址。
步骤203，根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。
在一实施例中，处理机获取由报文发送网元同步过来的关联规则，其中，关联规则用于将由lPv6地址池划分得到的多个地址段与多个处理机关联，然后，处理机从报文发送网元获取待发送报文及其源IP地址，再根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。所以，在接收下行报文时，路由器会将下行报文按照边界网关协议BGP回到上行同一个处理机。在本实施例中，由于处于同一地址段的IPv6报文地址可以聚合到同一个处理机，以避免上行出去的IPv6报文地址是离散的。基于此，通过处理机的聚合进行地址汇聚，从而无需经过NAT转换即可实现下行报文回到上行同一个设备。同时，由于避免了NAT转换，网络性能得到提升。
其中，边界网关协议BGP是运行于TCP上的一种自治系统AS的路由协议，其可以实现自治系统间通信，传播网络的可达信息。BGP是一个外部网关协议，允许一个AS与另一个AS进行通信。BGP允许一个AS向其他AS通告其内部的网络的可达性信息，或者是通过该AS可达的其他网络的路由信息。同时，AS也能够从另一个AS中了解这些信息。BGP为每个目的网络提供的是下一跳NextHop结点的信息。在BGP通告目的网络的可达性信息时，处理指定目的网络的下一跳信息之外，通告中还包括了通路向量，即去往该目的网络时需要经过的AS的列表，使接受者能够了解去往目的网络的通路信息。
在一实施例中，处理机位于虚拟防火墙。
在本实施例中，以下一跳网元为虚拟防火墙为例，虚拟防火墙有多个处理机，报文转发时，根据关联规则将待发送报文发送到防火墙的各个处理机，可以采用隧道或策略路由方式，虚拟防火墙可以根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器，以使得下行报文按照边界网关协议BGP回虚拟防火墙，虚拟防火墙可以对下行报文进行安全检查。
如图3所示，图3是本申请一个实施例提供的一种报文处理方法的流程图。该报文处理方法应用于报文处理装置，其中，报文处理装置包括报文发送网元和多个处理机，该方法包括但不限于如下步骤：
步骤301，报文发送网元获取关联规则，关联规则用于将由IPv6地址池划分得到的多个地址段与多个处理机关联；
步骤302，报文发送网元获取待发送报文及其源IP地址；
步骤303，报文发送网元根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。
步骤304，多个处理机获取由报文发送网元同步过来的关联规则；
步骤305，目的处理机从报文发送网元获取待发送报文及其源IP地址；
步骤306，目的处理机根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。
在一实施例中，报文发送网元获取关联规则，其中，关联规则用于将由lPv6地址池划分得到的多个地址段与多个处理机关联，然后，报文发送网元获取待发送报文及其源IP 地址，再根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。多个处理机获取由报文发送网元同步过来的关联规则，然后，目的处理机从报文发送网元获取待发送报文及其源IP地址，再根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。所以，在接收下行报文时，路由器会将下行报文按照边界网关协议BGP回到上行同一个处理机。在本实施例中，利用关联规则将由lPv6地址池划分得到的多个地址段与多个处理机关联起来，使得处于同一地址段的IPv6报文地址可以聚合到同一个处理机，以避免上行出去的IPv6报文地址是离散的。基于此，通过报文发送网元以及处理机进行地址汇聚，从而无需经过NAT转换即可实现下行报文回到上行同一个设备。同时，由于避免了NAT转换，网络性能得到提升。
如图4所示，图4是本申请一个实施例提供的一种报文处理装置的示意图。该报文处理装置包括报文发送网元和多个处理机。
其中，报文发送网元获取关联规则，关联规则用于将由IPv6地址池划分得到的多个地址段与多个处理机关联；
报文发送网元获取待发送报文及其源IP地址；
报文发送网元根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。
多个处理机获取由报文发送网元同步过来的关联规则；
目的处理机从报文发送网元获取待发送报文及其源IP地址；
目的处理机根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。
在一实施例中，报文发送网元获取关联规则，其中，关联规则用于将由lPv6地址池划分得到的多个地址段与多个处理机关联，然后，报文发送网元获取待发送报文及其源IP地址，再根据关联规则确定源lP地址所在地址段对应的目的处理机，将待发送报文发送至目的处理机。多个处理机获取由报文发送网元同步过来的关联规则，然后，目的处理机从报文发送网元获取待发送报文及其源IP地址，再根据关联规则确定源lP地址所在地址段，将待发送报文以及源lP地址所在地址段通过边界网关协议BGP发送给路由器。所以，在接收下行报文时，路由器会将下行报文按照边界网关协议BGP回到上行同一个处理机。在本实施例中，利用关联规则将由lPv6地址池划分得到的多个地址段与多个处理机关联起来，使得处于同一地址段的IPv6报文地址可以聚合到同一个处理机，以避免上行出去的IPv6报文地址是离散的。基于此，通过报文发送网元以及处理机进行地址汇聚，从而无需经过NAT转换即可实现下行报文回到上行同一个设备。同时，由于避免了NAT转换，网络性能得到提升。
在一实施例中，如图4所示，例如，报文发送网元先获取关联规则，在发送报文时，获取三个待发送报文地址，其具体分别为2001:0DB8::1428:57ab、2001:0DB8::1428:57ac、2001:0DB8::1428:57ad，再根据关联规则确定上述三个报文地址所在地址段为2001:0DB8::1428:0/48，与该地址段对应关联的目的处理机为虚拟防火墙vFW的处理机1，则将三个待发送报文2001:0DB8::1428:57ab、2001:0DB8::1428:57ac、2001:0DB8::1428:57ad发送给处理机1，再由处理机1把报文发送给出去，并把地址段2001:0DB8::1428:0/48通过边界网关协议BGP发送给路由器。这样，在接收下行报文时， 路由器会将下行报文按照边界网关协议BGP回到上行同一个处理机。
