本申请实施例描述的系统架构以及应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新应用场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本领域技术人员可以理解的是，图1中示出的系统架构的结构并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述系统架构的结构，提出本申请的信息处理方法的各个实施例。
如图2所示，图2是本申请一个实施例提供的信息处理方法的流程图，该信息处理方法应用于第二设备，并且第二设备设置有归属于第二备份组的第二端口(例如图1所示的第二BRAS120的第二端口121)，该信息处理方法包括但不限于有以下步骤：
步骤S110，在通过第二端口接收到数据报文的情况下，当在预设时间段内没有接收到来自第一设备的第一端口的第一保活报文，并且根据第一级联端口属性表确定第一端口的报文处理优先级为最高优先级，第二端口的报文处理优先级为次高优先级，则更新第一级联端口属性表使得第二端口的报文处理优先级为最高优先级，并转发数据报文。
需要说明的是，第一端口归属于第一备份组；第一级联端口属性表包括第一级联路由信息和第二级联路由信息，第一级联路由信息和第二级联路由信息用于使第一端口和第二端口形成级联备份组，第一级联路由信息还用于指示第一端口的报文处理优先级，第二级联路由信息还用于指示第二端口的报文处理优先级；第一保活报文用于使第二设备维持第一级联端口属性表中的第一级联路由信息。
在一实施例中，第二设备可以保存有第一级联端口属性表，该第一级联端口属性表包括有第一级联路由信息和第二级联路由信息，其中，第一级联路由信息和第二级联路由信息用于使第一端口和第二端口形成级联备份组，而且，第一级联路由信息还用于指示第一端口的报文处理优先级，第二级联路由信息还用于指示第二端口的报文处理优先级。需要说明的是，第二设备所保存的第一级联端口属性表，其获得方式可以有不同的实施方式，例如，可以为由人工编辑而得到，也可以为由第一设备与第二设备进行通信协商而获得，本实施例对此并不作具体限定。
在一实施例中，由于第二设备保存有包括有第一级联路由信息和第二级联路由信息的第一级联端口属性表，而第一级联路由信息和第二级联路由信息用于使第一端口和第二端口形成级联备份组，因此可以使得归属于不同备份组的第一端口和第二端口形成级联备份组，从而实现了不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。另外，在通过第二端口接收到数据报文的情况下，当在预设时间段内没有接收到来自第一端口的第一保活报文，则说明第一设备当前处于故障状态，此时，第二设备可以更新第一级联端口属性表使得第二端口的报文处理优先级为最高优先级，并通过第二端口转发数据报文，即，第二端口实现了对第一端口的报文处理的备份作用，从而能够保持数据报文的正常传输。
需要说明的是，当不同设备之间的端口根据级联端口属性表形成级联备份组后，这些端口之间会定期通过组播方式发送保活报文，以把本端口或本端口所在设备的工作状态通知同一级联备份组中的其他设备，例如本实施例中第一端口和第二端口根据第一级联端口属性表 形成级联备份组后，第一端口会定期通过组播方式向第二端口发送第一保活报文，以使第二设备维持第一级联端口属性表中的第一级联路由信息，即维持第一端口和第二端口之间的级联备份关系。如果同一级联备份组中的其中一个端口的保活报文丢失或者没有发送保活报文，说明该端口出现异常或者该端口所在的设备出现宕机，此时，该同一级联备份组中的其他端口均会对自身所维护的级联端口属性表进行更新，例如在级联端口属性表中把保活报文丢失或者没有发送保活报文的端口的表项内容进行删除或者进行去激活等，并且，该级联备份组中剩余的端口的级联优先级都将会发生变化。例如，在本实施例中，当根据第一级联端口属性表中确定第一设备的第一端口的报文处理优先级为当前级联备份组中的最高优先级，而第二设备的第二端口的报文处理优先级则为当前级联备份组中的次高优先级，并且当第二端口在预设时间段内都没有接收到由第一设备的第一端口所组播的第一保活报文时，会认为第一设备的第一端口出现异常或者第一设备出现宕机，为了保证业务数据的正常传输以及双机备份的正常执行，第二设备会更新第一级联端口属性表使得第二端口的报文处理优先级为最高优先级，即第二设备会更新为当前级联备份组中的主用级联设备，所以，当通过第二端口接收到数据报文时，第二端口作为当前级联备份组中的主用级联设备的端口，第二端口会对数据报文进行转发，从而实现了对第一端口的报文处理的备份作用，因此能够保持数据报文的正常传输。
值得注意的是，预设时间段可以根据实际应用情况而进行适当的选择，本实施例对此并不作具体限定。
另外，在一实施例中，步骤S110中的更新第一级联端口属性表使得第二端口的报文处理优先级为最高优先级，可以有不同的实施方式，例如，可以删除第一级联端口属性表中的第一级联路由信息，使得第二端口的报文处理优先级为最高优先级；或者，可以更改第一级联端口属性表中的第一级联路由信息，使得第二端口的报文处理优先级为最高优先级；或者，可以更改第一级联端口属性表中的第二级联路由信息，使得第二端口的报文处理优先级为最高优先级；或者，可以将第一级联端口属性表中的第一级联路由信息去激活，使得第二端口的报文处理优先级为最高优先级。
需要说明的是，当采用删除第一级联端口属性表中的第一级联路由信息的方式使得第二端口的报文处理优先级为最高优先级时，由于删除了用于指示第一端口的报文处理优先级为最高优先级的第一级联路由信息，因此，在当前的第一级联端口属性表中剩余的信息中，第二级联路由信息所对应的报文处理优先级从原来的次高优先级变成了最高优先级，即第二端口的报文处理优先级成为了最高优先级。当采用更改第一级联端口属性表中的第一级联路由信息的方式使得第二端口的报文处理优先级为最高优先级时，可以把第一级联路由信息所对应的报文处理优先级直接更改成比第二级联路由信息所对应的报文处理优先级更高的优先级，从而实现了使得第二端口的报文处理优先级为最高优先级的目的。当采用更改第一级联端口属性表中的第二级联路由信息的方式使得第二端口的报文处理优先级为最高优先级时，可以把第二级联路由信息所对应的报文处理优先级直接更改成比第一级联路由信息所对应的报文处理优先级更低的优先级，从而实现了使得第二端口的报文处理优先级为最高优先级的目的。当采用对第一级联路由信息进行去激活的方式使得第二端口的报文处理优先级为最高优先级时，由于用于指示第一端口的报文处理优先级为最高优先级的第一级联路由信息被去激活，即第一级联路由信息不起作用，因此，在当前的第一级联端口属性表中剩余的信息中，第二 级联路由信息所对应的报文处理优先级从原来的次高优先级变成了最高优先级，即第二端口的报文处理优先级成为了最高优先级。
另外，在一实施例中，参照图3，该信息处理方法还可以包括但不限于有以下步骤：
步骤S120，在通过第二端口接收到数据报文的情况下，当在预设时间段内接收到第一保活报文，并且根据第一级联端口属性表中的第二级联路由信息确定第二端口的报文处理优先级为最高优先级，转发数据报文。
在一实施例中，当第二设备在预设时间段内接收到第一保活报文，则说明第一设备处于正常工作状态，此时，当根据第一级联端口属性表中的第二级联路由信息确定第二端口的报文处理优先级为最高优先级，即说明第二设备为当前级联备份组中的主用级联设备，而第二端口则为当前级联备份组中的主用级联设备的端口，所以，在通过第二端口接收到数据报文的情况下，第二端口会对该数据报文进行转发。
另外，在一实施例中，参照图4，该信息处理方法还可以包括但不限于有以下步骤：
步骤S130，在通过第二端口接收到数据报文的情况下，当在预设时间段内接收到第一保活报文，并且根据第一级联端口属性表中的第二级联路由信息确定第二端口的报文处理优先级为非最高优先级，丢弃数据报文。
值得注意的是，本实施例中的步骤S130和如图3所示实施例中的步骤S120互为并列的技术方案。
在一实施例中，当第二设备在预设时间段内接收到第一保活报文，则说明第一设备处于正常工作状态，此时，当根据第一级联端口属性表中的第二级联路由信息确定第二端口的报文处理优先级为非最高优先级，即说明第二设备为当前级联备份组中的备用级联设备，而第二端口则为当前级联备份组中的备用级联设备的端口，所以，在通过第二端口接收到数据报文的情况下，第二端口会丢弃该数据报文而不会对该数据报文进行转发。
另外，在一实施例中，参照图5，在通过第二端口接收到数据报文之前，该信息处理方法还可以包括但不限于有步骤S140、步骤S150和步骤S160。
步骤S140，通过第二端口获取由第一端口组播的第一协议报文，第一协议报文携带有第一级联路由信息。
在一实施例中，由第一设备的第一端口所组播的第一协议报文，可以为承载在组播方式的UDP协议上的报文，也可以为承载在组播方式的其他协议上的报文，例如承载在随着系统架构的演变或新应用场景的出现而对应形成的协议上的报文，本实施例对此并不作具体限定。
在一实施例中，第一设备的第一端口归属于第一备份组(例如图1所示的第一BRAS110的第一端口111)，第二设备的第二端口归属于第二备份组，而第一设备和第二设备分别为不同厂家的设备。由于第一协议报文携带有与第一端口对应的第一级联路由信息，因此，当第二设备接收到该第一协议报文所携带的第一级联路由信息后，可以在后续步骤中根据该第一级联路由信息使第一端口与第二端口形成级联备份组，从而能够实现不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。
在一实施例中，第一级联路由信息包括但不限于有与第一端口对应的第一端口号、与第一端口对应的第一级联组标识和与第一端口对应的第一级联优先级；第一协议报文设置有第一端口信息字段和第一级联信息字段，其中，第一级联信息字段设置有第一级联组标识字段和第一属性字段。其中，第一级联组标识字段携带第一级联组标识，第一属性字段携带第一 级联优先级，第一端口信息字段携带第一端口号。
在一实施例中，第一级联信息字段还可以设置有第一信息类型字段，该第一信息类型字段携带有与第一端口对应的第一级联类型信息，用于指示第一协议报文的类型。
在一实施例中，第一协议报文可以为采用组播方式的UDP协议报文，由于UDP协议报文本身设置有用于携带第一端口号的第一端口信息字段，因此可以在UDP协议报文中新增第一级联信息字段，以使该UDP协议报文能够携带第一级联组标识和第一级联优先级。
下面以具体的示例进行说明：
在一示例中，在第一协议报文为采用组播方式的UDP协议报文的情况下，可以在第一协议报文中新增第一级联信息字段，并且第一级联信息字段设置有第一级联组标识字段和第一属性字段。参照图6，图6示意性地给出了携带有第一级联类型信息、第一级联组标识和第一级联优先级的第一级联信息字段的结构，在该第一级联信息字段的结构中，各主要字段的解释如下：
Ver：版本号字段，占1字节，用于表示协议版本号；
Message Type：信息类型字段，占1字节，用于表示本协议报文的作用类型；具体为：当取值为0x01，表示本协议报文的作用类型为新增级联路由信息；当取值为0x02，表示本协议报文的作用类型为删除级联路由信息；当取值为0x03，表示本协议报文的作用类型为更新级联路由信息；当取值为0x04，表示本协议报文为保活报文(例如图2所示实施例中的第一保活报文)；
Message Length：信息长度字段，占2字节，用于表示本协议报文的报文总长度；
Cascade-Group-ID：级联组标识字段，占4字节，用于表示发送本协议报文的端口所属的级联组的ID号；
Data：属性字段，长度可变的TLV格式，用于承载本协议报文的报文信息。
在上述第一级联信息字段的结构中，Message Type字段即为第一信息类型字段，Cascade-Group-ID字段即为第一级联组标识字段，Data字段即为第一属性字段。具体地，参照图7，在Data字段中，主要包括如下字段：
Type：占2字节，用于表示数据的属性类型或业务信息表属性；
Length：占2字节，用于表示本Data字段中不包括Type字段和Length字段的长度；
Value：用于携带数据信息，可以根据实际需要而进行自定义增加，与Type字段的内容相互配合以表示数据的具体信息。
其中，作为示例，当Type字段取值为0时，Value字段可以填写级联设备的IP地址(例如第一设备的IP地址)；当Type字段取值为1时，Value字段可以填写级联设备的优先级(例如第一端口所对应的第一级联优先级)。值得注意的是，Data字段的数量可以有多个，多个Data字段依次链接，用以承载完整的报文信息，例如Data字段的数量为2个，其中一个Data字段携带第一级联优先级，而另一个Data字段携带第一设备的IP地址。
值得注意的是，第一端口所对应的第一端口号，可以携带在UDP协议报文的UDP报文头中，可以根据现有的网络规范进行定义，本实施例对此并不作具体限定。
因此，即使第一设备的第一端口归属于第一备份组(例如图1所示的第一BRAS110的第一端口111)，第二设备的第二端口归属于第二备份组，并且第一设备和第二设备分别为不同厂家的设备，但是，由于第一协议报文携带有与第一端口对应的第一级联路由信息，并且 该第一级联路由信息至少包括第一级联类型信息、第一端口号、第一级联组标识和第一级联优先级，因此，当第二设备接收到该第一协议报文所携带的该第一级联路由信息后，可以在后续步骤中根据第一级联类型信息、第一端口号、第一级联组标识和第一级联优先级等信息使第一端口与第二端口形成级联备份组，从而能够实现不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。
步骤S150，获取第二级联路由信息。
在一实施例中，第二级联路由信息可以包括与第二端口对应的第二端口号、与第二端口对应的第二级联组标识和与第二端口对应的第二级联优先级，本实施例对此并不作具体限定。另外，第二设备可以预先配置有与第二端口对应的第二级联路由信息，因此第二设备可以直接获取第二级联路由信息中的第二端口号、第二级联组标识和第二级联优先级等信息，从而方便后续步骤中可以根据第二端口号、第二级联组标识和第二级联优先级等信息以及第一级联类型信息、第一端口号、第一级联组标识和第一级联优先级等信息使第一端口与第二端口形成级联备份组，从而能够实现不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。
在一实施例中，第二设备可以预先配置有级联路由信息表，该级联路由信息表中可以记录有第二端口所对应的第二级联路由信息和第二设备的其他端口所对应的级联路由信息，因此，第二设备可以通过读取级联路由信息表的方式获取与第二端口对应的第二级联路由信息。
步骤S160，根据第二级联路由信息和第一协议报文中的第一级联路由信息，构建第一级联端口属性表。
在一实施例中，由于第二级联路由信息包括有第二端口所对应的第二端口号、第二端口所对应的第二级联组标识和第二端口所对应的第二级联优先级等信息，而第一级联路由信息包括有第一端口所对应的第一端口号、第一端口所对应的第一级联组标识和第一端口所对应的第一级联优先级等信息，因此可以根据第二级联路由信息和第一级联路由信息使第一端口和第二端口形成级联备份组，并且构建与该级联备份组对应的第一级联端口属性表，以便于后续步骤中，可以使第二端口根据该第一级联端口属性表对数据报文进行相关的处理。
在一实施例中，通过采用包括有上述步骤S140、步骤S150和步骤S160的信息处理方法，使得在第一设备的第一端口和第二设备的第二端口归属于不同的备份组的情况下，当第二设备通过第二端口获取由第一设备的第一端口所组播的第一协议报文，并且第一协议报文携带有与第一端口对应的第一级联路由信息，第二设备可以根据与第二端口对应的第二级联路由信息以及该第一协议报文中的第一级联路由信息，使第一端口和第二端口形成级联备份组并构建与该级联备份组对应的第一级联端口属性表，从而使得第二设备在通过第二端口接收到数据报文时，可以根据该第一级联端口属性表对数据报文进行报文处理。因此，通过利用携带有第一级联路由信息的第一协议报文，即可使得归属于不同备份组的设备的端口之间能够形成级联备份组，例如可以在不同厂家的设备的端口之间形成级联备份组，从而能够实现不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。
值得注意的是，归属于第一备份组的第一端口所在的第一设备和归属于第二备份组的第二端口所在的第二设备，可以安装在同一个机房内，也可以分别处于不同的地点，例如，第一设备和第二设备分别处于不同的城市，只需第一设备和第二设备均与同一接入汇聚设备连接即可。另外，第一设备和第二设备所处的网络域中，还可以包括有多个其他设备，该网络 域中的这些设备可以分布在不同城市中，这些设备的端口之间还可以形成有第三备份组、第四备份组乃至第N备份组，不同的备份组之间均可以通过采用包括有上述步骤S140、步骤S150和步骤S160的信息处理方法以形成级联备份组。
另外，在一实施例中，参照图8，步骤S160可以包括但不限于有以下步骤：
步骤S161，当第一级联类型信息为新增级联信息，根据第一端口号、第一级联组标识、第一级联优先级、第二端口号、第二级联组标识和第二级联优先级，构建第一级联端口属性表。
在一实施例中，当通过第二端口获取到的第一协议报文中所携带的第一级联类型信息为新增级联信息时，即当如图6所示实施例中的Message Type字段取值为0x01时，说明第一设备的第一端口希望与第二设备的第二端口形成级联备份组，此时，第二设备即可根据第一端口号、第一级联组标识、第二端口号和第二级联组标识使第一端口和第二端口形成级联备份组。例如，当第一设备的第一端口所对应的第一级联组标识和第二设备中预先配置的第二端口的第二级联组标识不相同，则第一端口和第二端口不能形成级联备份组；当第一设备的第一端口所对应的第一级联组标识和第二设备中预先配置的第二端口的第二级联组标识相同，即可把第一端口和第二端口形成级联备份组，从而可以实现第一端口和第二端口之间的双机备份。
在一实施例中，当第一端口和第二端口形成级联备份组后，可以根据第一端口号、第一级联组标识、第一级联优先级、第二端口号、第二级联组标识和第二级联优先级，构建与该级联备份组对应的第一级联端口属性表，使得传输到第一端口和第二端口的数据报文能够根据第一级联端口属性表而进行相应的报文处理。
在一实施例中，如图9所示，示意性地给出了第一级联端口属性表的结构，在该结构中，第一级联端口属性表可以包括有端口号信息、厂家信息、虚拟路由冗余协议(Virtual Router Redundancy Protocol，VRRP)组信息、VRRP优先级信息和级联组信息。其中，VRRP组信息中表项内容相同的端口之间会形成本技术领域中的双机热备；级联组信息包括级联组标识(如图9中的“第一级联备份组”)和级联优先级(如图9中“第一级联备份组-主”中的“主”)，级联组标识相同的端口之间会形成级联备份组并具备双机备份功能，级联优先级则指示级联备份组中端口对数据报文的处理优先程度。
另外，在一实施例中，参照图10，该信息处理方法还可以包括但不限于有以下步骤：
步骤S170，通过第二端口接收由第一端口组播的第二协议报文，第二协议报文携带有第二级联类型信息和第三级联路由信息；
步骤S180，根据第二级联类型信息和第三级联路由信息维护第一级联端口属性表。
在一实施例中，第三级联路由信息也可以包括有端口号、级联组标识、级联优先级和级联类型信息等信息。在第一端口和第二端口形成级联备份组后，当第二设备通过第二端口接收到由第一设备的第一端口所组播的第二协议报文，并且该第二协议报文携带有第二级联类型信息和第三级联路由信息时，第二设备可以根据该第二协议报文中的第二级联类型信息和第三级联路由信息维护第一级联端口属性表。
在一实施例中，第二级联类型信息可以为删除级联信息或者更新级联信息，本实施例对此并不作具体限定。例如，当第二级联类型信息为删除级联信息时，维护第一级联端口属性表的具体操作可以为删除第一级联端口属性表中与第一端口对应的表项内容(例如第一级联 路由信息)；当第二级联类型信息为更新级联信息时，维护第一级联端口属性表的具体操作可以为利用第三级联路由信息对第一级联端口属性表中与第一端口对应的表项内容进行更新。
值得注意的是，本实施例中的第二协议报文，和上述实施例中的第一协议报文同样为UDP协议报文，并且第二协议报文和第一协议报文具有相同的报文结构，对于第二协议报文的具体报文结构，可以参照上述如图6和图7所示的报文结构，此处不再赘述。
另外，在一实施例中，参照图11，步骤S180可以包括但不限于有以下步骤：
步骤S181，当第二级联类型信息为删除级联信息，删除第一级联端口属性表中的第一级联路由信息。
在一实施例中，在第二设备通过第二端口接收到由第一设备的第一端口所组播的第二协议报文的情况下，当第二级联类型信息为删除级联信息，例如如图6所示实施例中的Message Type字段取值为0x02时，即说明第二协议报文的作用为删除第一级联端口属性表中与第一端口对应的表项内容(例如第一级联路由信息)，因此，第二设备可以根据该第二级联类型信息的指示而删除第一级联端口属性表中与第一端口对应的表项内容。
另外，在一实施例中，参照图12，步骤S180还可以包括但不限于有以下步骤：
步骤S182，当第二级联类型信息为更新级联信息，根据第三级联路由信息更新第一级联端口属性表中的第一级联路由信息。
值得注意的是，本实施例中的步骤S182和如图11所示实施例中的步骤S181互为并列的技术方案。
在一实施例中，在第二设备通过第二端口接收到由第一设备的第一端口所组播的第二协议报文的情况下，当第二级联类型信息为更新级联信息，例如如图6所示实施例中的Message Type字段取值为0x03时，即说明第二协议报文的作用为对第一级联端口属性表中与第一端口对应的表项内容(例如第一级联路由信息)进行更新，因此，第二设备可以根据该第二级联类型信息的指示而利用第三级联路由信息对第一级联端口属性表中与第一端口对应的表项内容进行更新。
另外，在一实施例中，参照图13，该信息处理方法还可以包括但不限于有以下步骤：
步骤S210，通过第二端口对外组播携带有第二级联路由信息的第三协议报文，使得通过第一端口接收到第三协议报文的第一设备根据第一级联路由信息和第三协议报文中的第二级联路由信息，构建包括有第一级联路由信息和第二级联路由信息的第二级联端口属性表，并使得第一设备在通过第一端口接收到数据报文的情况下，根据第二级联端口属性表对数据报文进行报文处理。
在一实施例中，第二设备通过第二端口获取由第一设备的第一端口所组播的第一协议报文的同时，第二设备的第二端口也会通过组播方式对外发送第三协议报文。在这个过程中，第二设备可以先根据第二端口所对应的第二级联路由信息构建第三协议报文，然后通过第二端口对外组播第三协议报文。值得注意的是，本实施例中的第三协议报文，和上述实施例中的第一协议报文同样为UDP协议报文，并且第三协议报文和第一协议报文具有相同的报文结构，对于第三协议报文的具体报文结构，可以参照上述如图6和图7所示的报文结构，此处不再赘述。
在一实施例中，第二设备通过第二端口对外组播携带有第二级联路由信息的第三协议报文，当第一设备的第一端口接收到该第三协议报文，第一设备可以根据该第三协议报文中的 第二级联路由信息和第一设备预先配置的与第一端口对应的第一级联路由信息，使第一端口和第二端口形成级联备份组并构建与该级联备份组对应的第二级联端口属性表，从而使得第一设备在通过第一端口接收到数据报文时，可以根据该第二级联端口属性表对数据报文进行报文处理。因此，在第一设备的第一端口和第二设备的第二端口归属于不同的备份组的情况下，通过利用携带有第二级联路由信息的第三协议报文，即可使得归属于不同备份组的设备的端口之间能够形成级联备份组，例如可以在不同厂家的设备的端口之间形成级联备份组，从而能够实现不同厂家之间的设备的双机备份，从而能够方便运营商的网络布设。
值得注意的是，本实施例中的第二级联端口属性表的结构，和如图9所示实施例中的第一级联端口属性表的结构相同，对于第二级联端口属性表的具体结构，可以参照上述如图9所示的表格结构，此处不再赘述。
另外，在一实施例中，该信息处理方法还可以包括但不限于有以下步骤：
通过第二端口对外组播携带有第三级联类型信息和第四级联路由信息的第四协议报文，使得通过第一端口接收到第四协议报文的第一设备根据第四协议报文中的第三级联类型信息和第四级联路由信息维护第二级联端口属性表。
在一实施例中，第四级联路由信息也可以包括有端口号、级联组标识、级联优先级和级联类型信息等信息。在第一端口和第二端口形成级联备份组后，当第一设备通过第一端口接收到由第二设备的第二端口所组播的第四协议报文，并且该第四协议报文携带有第三级联类型信息和第四级联路由信息时，第一设备可以根据该第四协议报文中的第三级联类型信息和第四级联路由信息维护第二级联端口属性表。
在一实施例中，第三级联类型信息也可以为删除级联信息或者更新级联信息，本实施例对此并不作具体限定。例如，当第三级联类型信息为删除级联信息时，维护第二级联端口属性表的具体操作可以为删除第二级联端口属性表中与第二端口对应的表项内容；当第三级联类型信息为更新级联信息时，维护第二级联端口属性表的具体操作可以为利用第四级联路由信息对第二级联端口属性表中与第二端口对应的表项内容进行更新。
值得注意的是，本实施例中的第四协议报文，和上述实施例中的第一协议报文同样为UDP协议报文，并且第四协议报文和第一协议报文具有相同的报文结构，对于第四协议报文的具体报文结构，可以参照上述如图6和图7所示的报文结构，此处不再赘述。
另外，在一实施例中，该信息处理方法还可以包括但不限于有以下步骤：
通过第二端口对外组播第二保活报文，使得通过第一端口接收到第二保活报文的第一设备根据第二保活报文维持第二级联端口属性表中与第二端口对应的表项内容。
在一实施例中，在第一端口和第二端口形成级联备份组后，当第一设备通过第一端口接收到由第二设备的第二端口所组播的第二保活报文，第一设备可以根据该第二保活报文维持第二级联端口属性表中的第二级联路由信息。
值得注意的是，本实施例中的第二保活报文，和上述实施例中的第一协议报文同样为UDP协议报文，并且第二保活报文和第一协议报文具有相同的报文结构，对于第二保活报文的具体报文结构，可以参照上述如图6和图7所示的报文结构，此处不再赘述。
在一实施例中，第二保活报文也可以包括有端口号、级联组标识、级联优先级和级联类型信息等信息。值得注意的是，第二保活报文与第三协议报文及第四协议报文的主要区别在于，第二保活报文中的级联类型信息为保活报文，例如如图6所示实施例中的Message Type 字段取值为0x04。形成级联备份组的端口之间，均需要定时发送保活报文，以保证形成级联备份组的端口均处于激活状态，并且维持对应的级联端口属性表中的表项内容，以便于级联备份组中的端口能够根据该级联端口属性表中的表项内容执行双机备份时的数据报文的处理。
为了更加清楚的说明上述各个实施例中信息处理方法的具体步骤流程，下面以具体的示例进行说明。
示例一：
如图1所示，第一BRAS110的第一端口111和第三BRAS130的第五端口131通过第一厂家的私有双机热备协议形成第一备份组，第一BRAS110的第三端口112和第三BRAS130的第七端口132通过第一厂家的私有双机热备协议形成第三备份组；第二BRAS120的第二端口121和第四BRAS140的第六端口141通过第二厂家的私有双机热备协议形成第二备份组，第二BRAS120的第四端口122和第四BRAS140的第八端口142通过第二厂家的私有双机热备协议形成第四备份组。
在第一厂家的第一BRAS110和第三BRAS130分别部署端口级联，其中，部署第一BRAS110的第一端口111在第一级联备份组中，并且级联优先级为1；部署第三BRAS130的第五端口131在第一级联备份组中，并且级联优先级为1。在第二厂家的第二BRAS120和第四BRAS140分别部署端口级联，其中，部署第二BRAS120的第二端口121在第一级联备份组中，并且级联优先级为7；部署第四BRAS140的第六端口141在第一级联备份组中，并且级联优先级为7。
当完成上述级联信息的部署后，各个端口通过组播方式发送携带有级联类型信息为新增级联信息的UDP协议报文，具体地：
第一端口111发送携带有如下信息的UDP协议报文：Ver＝0X01、Message Type＝0X01、Cascade-Group-ID＝0X01，IP地址＝第一BRAS110的IP地址，级联优先级＝0X01；
第五端口131发送携带有如下信息的UDP协议报文：Ver＝0X01、Message Type＝0X01、Cascade-Group-ID＝0X01，IP地址＝第三BRAS130的IP地址，级联优先级＝0X01；
第二端口121发送携带有如下信息的UDP协议报文：Ver＝0X01、Message Type＝0X01、Cascade-Group-ID＝0X01，IP地址＝第二BRAS120的IP地址，级联优先级＝0X07；
第六端口141发送携带有如下信息的UDP协议报文：Ver＝0X01、Message Type＝0X01、Cascade-Group-ID＝0X01，IP地址＝第四BRAS140的IP地址，级联优先级＝0X07。
当各个端口对应接收到由其他端口所组播的UDP协议报文后，各个端口都会根据自身的级联路由信息和所接收到的UDP协议报文中的级联路由信息，形成对应的级联备份组，例如，第一BRAS110的第一端口111被部署在第一级联备份组中，而第二BRAS120的第二端口121所组播的UDP协议报文中的级联组标识为0X01，即说明第一端口111和第二端口121都被部署在第一级联备份组中，所以第一端口111和第二端口121可以加入到第一级联备份组中。
当各个端口加入到对应的级联备份组后，各个端口均会根据自身的级联路由信息和所接收到的UDP协议报文中的级联路由信息构建并维护各自的级联端口属性表，并且根据各自的级联端口属性表按照预置的逻辑判断转发数据报文或者丢弃数据报文。
具体地，参照图1和图9，当第一BRAS110的第一端口111接收到终端用户发送的数据流量时，第一端口111根据级联端口属性表判断本端口为第一级联备份组的主用级联端口，并且第一端口111判断本端口为第一备份组中的主用端口，因此第一端口111进行数据流量的转发处理。当第三BRAS130的第五端口131接收到终端用户发送的数据流量时，第五端口 131根据级联端口属性表判断本端口为第一级联备份组的主用级联端口，但第五端口131判断本端口为第一备份组中的备用端口，因此第五端口131不进行数据流量的处理，丢弃该数据流量。当第二BRAS120的第二端口121接收到终端用户发送的数据流量时，第二端口121根据级联端口属性表判断本端口为第一级联备份组的备用级联端口，当主用级联端口(即第一端口111)正常工作时，第二端口121不进行数据流量的处理，丢弃该数据流量。当第四BRAS140的第六端口141接收到终端用户发送的数据流量时，第六端口141根据级联端口属性表判断本端口为第一级联备份组的备用级联端口，当主用级联端口(即第一端口111)正常工作时，第六端口141不进行数据流量的处理，丢弃该数据流量。
当第一接入汇聚设备150同时向第一端口111、第五端口131、第二端口121和第六端口141发送终端用户的数据流量时，这4个端口都会接收到终端用户的数据流量。当第一BRAS110出现宕机情况时，第一端口111不会接收到终端用户的数据流量。当第五端口131接收到终端用户的数据流量时，第五端口131根据级联端口属性表判断本端口为第一级联备份组的主用级联端口，并且为第一备份组中的备用端口，但由于第一BRAS110已经发生宕机，第五端口131会升级为第一备份组中的主用端口，因此第五端口131会进行数据流量的转发处理。当第二端口121接收到终端用户的数据流量时，第二端口121根据级联端口属性表判断本端口为第一级联备份组的备用级联端口，当主用级联端口(即第五端口131)正常工作时，第二端口121不进行数据流量的处理，丢弃该数据流量。当第六端口141接收到终端用户的数据流量时，第六端口141根据级联端口属性表判断本端口为第一级联备份组的备用级联端口，当主用级联端口(即第五端口131)正常工作时，第六端口141不进行数据流量的处理，丢弃该数据流量。
当第一接入汇聚设备150同时向第一端口111、第五端口131、第二端口121和第六端口141发送终端用户的数据流量时，这4个端口都会接收到终端用户的数据流量。当第一BRAS110出现宕机情况时，第一端口111不会接收到终端用户的数据流量。当第三BRAS130也出现宕机情况时，第五端口131也不会接收到终端用户的数据流量。此时，当第二BRAS120和第四BRAS140检测到第一BRAS110和第三BRAS130均出现了宕机的情况，第二BRAS120和第四BRAS140会升级为第一级联备份组的主用级联设备。此时，当第二端口121接收到终端用户的数据流量时，第二端口121根据级联端口属性表判断本端口为第一级联备份组的主用级联端口，并且为第二备份组中的主用端口，因此第二端口121会进行数据流量的转发处理。当第六端口141接收到终端用户的数据流量时，第六端口141根据级联端口属性表判断本端口为第一级联备份组的主用级联端口，但第六端口141判断本端口为第二备份组中的备用端口，因此第六端口141不进行数据流量的处理，丢弃该数据流量。
