本发明的实施方式
下文中将结合附图对本发明的实施方式进行详细说明。需要说明的是，在不冲突的情况下，本文中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本发明针对相关技术中的数据转发链路和协议控制链路使用同一条物理链路，在实际使用过程中，业务报文和协议报文就不可避免相互影响，从而产生业务丢包或堆叠系统不稳定等问题，提供一种堆叠系统协议控制和转发链路分离的方法，通过自动将堆叠系统的协议控制链路和数据转发链路分开，实现二者去耦合，避免链路间的相互干扰。
如图1所示，为本发明实施例提供的一种堆叠系统协议控制和转发链路分离的方法的流程图，本发明实施例提供的堆叠系统协议控制和转发链路分离的方法，应用于交换机中，所述交换机已开启堆叠模式，该方法包括步骤11～步骤13：
步骤11，通过已配置的堆叠端口发送堆叠邻居发现消息。
在本实施例中，由于交换机已开启堆叠模式，该交换机会进行堆叠端口的配置，因此，可通过该些堆叠端口发送堆叠邻居发现消息，以发现与该交换机处于同一堆叠系统的一个或多个交换机，而发现的交换机可以称为本交换机的堆叠邻居。
步骤12，根据接收到的堆叠邻居发现消息对应的堆叠邻居响应消息，确定交换机对应堆叠邻居的协议控制链路和数据转发链路的对数。
在本实施例中，堆叠邻居在接收到堆叠邻居发现消息后，会返回堆叠邻居响应消息，该交换机通过堆叠邻居响应消息可以确定该交换机对应堆叠邻居的协议控制链路和数据转发链路的对数，交换机会为每个堆叠邻居配设一 对协议控制链路和数据转发链路，当然，一般情况下协议控制链路只有一条，而数据转发链路并不一定是一条，可能是多条。
步骤13，根据交换机对应堆叠邻居的协议控制链路和数据转发链路的对数以及预先设置的规则，分离协议控制链路和数据转发链路。
按照上述步骤，本发明的实施例通过已配置的堆叠端口发送堆叠邻居发现消息，以发现该交换机的堆叠邻居，在接收到返回的堆叠邻居响应消息后，就能够确定该交换机对应堆叠邻居的协议控制链路和数据转发链路的对数，随后再根据协议控制链路和数据转发链路的对数以及预先设置的规则，分离协议控制链路和数据转发链路，分别通过堆叠建立协议和数据转发协议处理。这样，可如图4所示，为应用了本发明实施例的方法后的堆叠系统，将堆叠系统中相邻的交换机1、交换机2通过不同物理链路分别实现协议控制链路和数据转发链路，自动将协议控制链路和数据转发链路分开，实现二者的去耦合，避免链路间的相互干扰。
其中，所述堆叠邻居发现消息还可以通过已知协议邻居发现协议LLDP实现。
可选地，如图2所示，为本发明实施例提供的另一种堆叠系统协议控制和转发链路分离的方法的流程图。在上述图1所示实施例的基础上，本实施例中的步骤12可以包括步骤121～步骤123：
步骤121，获取接收到的堆叠邻居发现消息对应的堆叠邻居响应消息中的硬件MAC地址，其中，MAC地址为媒体访问控制(Media Access Control)地址。
在步骤11中，通过已配置的堆叠端口发送堆叠邻居发现消息，以发现该交换机的堆叠邻居，因此，该交换机的堆叠邻居在接收到堆叠邻居发现消息后，会返回堆叠邻居响应消息，而在该堆叠响应消息中就能够获取到返回堆叠邻居响应消息的堆叠邻居的MAC地址。若没有接收到堆叠邻居响应消息，会发出告警，提示用户确认交换机间的端口已经连接。
步骤122，根据MAC地址，确定与交换机建立堆叠的堆叠邻居的数目。
在实际应用中，堆叠系统中每个交换机有一个MAC地址，故通过MAC 的数目就能够确定与本交换机建立堆叠的堆叠邻居的数目。
步骤123，根据堆叠邻居的数目，确定交换机对应堆叠邻居的协议控制链路和数据转发链路的对数。
该交换机不论有几个堆叠邻居，对应每个堆叠邻居只有一对协议控制链路和数据转发链路，因此，可根据堆叠邻居的数目，确定交换机对应堆叠邻居的协议控制链路和数据转发链路的对数。
以交换机A、交换机B和交换机C的堆叠系统为例予以说明，交换机A通过堆叠端口发送堆叠邻居发现消息，交换机B和交换机C在接收到堆叠邻居发现消息后，向交换机A返回堆叠邻居响应消息，堆叠邻居响应消息中均携带发送该消息的交换机的MAC地址，交换机A接收到5条堆叠邻居响应消息，2条携带交换机B的MAC地址，3条携带交换机C的MAC地址，A通过判断接收到的MAC地址为两种，确定其堆叠邻居有两个，从而确定有两对协议控制链路和数据转发链路。
本发明实施例中，配置堆叠端口可能众多，通过堆叠端口发送的堆叠邻居发现消息，若端口连通，就能够接收到堆叠邻居返回的响应消息，而要从众多响应消息中确定是哪个堆叠邻居发送的就可通过MAC地址来确定，确定堆叠邻居的数目，确定交换机对应堆叠邻居的协议控制链路和数据转发链路的对数。
可选地，如图3所示，为本发明实施例提供的又一种堆叠系统协议控制和转发链路分离的方法的流程图。在上述图1所示实施例的基础上，本实施例中的步骤13可以包括步骤131～步骤134：
步骤131，根据交换机对应堆叠邻居的协议控制链路和数据转发链路的对数，获取每个堆叠邻居的端口信息；其中，该端口信息包括端口的数目、带宽、编号(Identification，简称为：ID)和业务量。
知道了交换机对应堆叠邻居的协议控制链路和数据转发链路的对数，可以确定每个堆叠邻居具有哪些端口，就可获取到每个堆叠邻居的端口信息，该端口信息例如端口的数目、带宽、ID和业务量等，ID是指该端口在其所属交换机的端口号。
步骤132，在堆叠邻居的端口数目大于预设值时，根据预先设定的规则，选择堆叠邻居的端口中的预设数量的端口作为协议控制端口。
一般情况协议控制链路只需要一条，而数据转发链路往往不做要求。在堆叠邻居与本交换机连通的端口数目与协议控制链路需要数目相同时，就不存在链路分离的必要了，只有在堆叠邻居的端口数目大于一预设值时，才需要根据预先设定的规则，选择所述堆叠邻居的端口中的预设数量的端口作为协议控制端口。在实际应用中，上述预设值可以是根据协议控制链路的需求设置的，该预设值也就是该预设数量的值。
步骤133，选择堆叠邻居的剩余端口作为数据转发端口。
在选择了协议控制端口后，堆叠邻居的端口中的剩余的端口就能够作为数据转发端口了。协议控制链路之间可使用链路汇聚控制协议(Link Aggregation Control Protocol，简称为：LACP)调度，数据转发链路之间也可以使用LACP调度。
步骤134，根据选择的协议控制端口和数据转发端口分离协议控制链路和数据转发链路。
选择后确定了堆叠邻居的协议控制端口和数据转发端口，就可通过对应端口的物理链路实现协议控制链路和数据转发链路，分离了协议控制链路和数据转发链路。
同样以上述实例予以说明，交换机A确定其堆叠邻居有两个，从而确定有两对协议控制链路和数据转发链路后，也就能够确定交换机A的五个端口A1-A5对应交换机B的两个端口B1、B2，对应交换机C的三个端口C1、C2、C3，然后获取每个堆叠邻居的端口信息。假设交换机A和交换机C之间端口对应关系为A1-C1，A2-C2，A3-C3，获取交换机C的三个端口的端口信息，此时预设值为1，再根据预先设定的规则，就可以在C1、C2、C3中选择出一个端口作为协议控制端口假设是C1，剩余的两个端口C2和C3就可作为数据转发端口。C1对应A1，链路A1C1就可设置为协议控制链路，链路A2C2和A3C3设置为数据转发链路，这样，实现了协议控制链路和数据转发链路的分离。
本发明实施例中，根据交换机对应堆叠邻居的协议控制链路和数据转发 链路的对数获取每个堆叠邻居的端口信息，对每一个堆叠邻居的端口进行选择。根据预先设定的规则，选择出本交换机与堆叠邻居的协议控制端口和数据转发端口，分离协议控制链路和数据转发链路，实现了二者的去耦合，避免了链路间的干扰。
可选地，在本发明的一个实施例中，步骤132可以包括步骤132a～步骤132c其中之一：
步骤132a，根据端口信息中的带宽，选择堆叠邻居中带宽最小的端口为协议控制端口，若端口的带宽相同，则选择ID最小的端口为协议控制端口；或者，
步骤132b，根据述端口信息中的业务量，选择堆叠邻居中业务量最多的端口为协议控制端口，若端口的业务量相同，则选择ID最小的端口为协议控制端口；或者，
步骤132c，根据端口信息中的ID，选择堆叠邻居中ID最小的端口为协议控制端口。
本实施例中的端口信息包括带宽、ID和业务量等，可以选择带宽最小的端口为协议控制端口，当然若出现端口的带宽相同的情况，则选择ID最小的端口为协议控制端口；可以选择业务量最多的端口为协议控制端口，当然若出现端口的业务量相同的情况，则选择ID最小的端口为协议控制端口；还可以直接选择ID最小的端口为协议控制端口。在实际应用中，预设规则并不仅限于上述的情况，还可以是上述的一种或多种标准的加权组合，也可以根据其他端口信息设置，在此不一一列举。
还应该知道的是，在堆叠系统中交换机互为堆叠邻居，每个交换机都在对方的端口中进行选择，这样可能出现如：交换机A可能选择交换机B的端口B2作为协议控制端口，而交换机A对应B2的端口是A5，但是交换机B选择交换机A的端口A4作为协议控制端口，就不可避免的会出现选择的冲突情况，因此，可选地，步骤13还可以包括：
步骤135，获取堆叠邻居的端口选定信息，其中，该端口选定信息用于表示该堆叠邻居选定的交换机的协议控制端口；
步骤136，在交换机选定的协议控制端口与堆叠邻居选定的协议控制端口不是对应端口时，根据该交换机和该堆叠邻居的MAC地址大小确定协议控制链路的端口。
通过获取本交换机的堆叠邻居的端口选定信息来了解该堆叠邻居选择的协议控制端口是否与本交换机选择的协议控制端口对应，若对应则可以直接分离链路，但若不对应，就需要对二者进行统一，可以比较本交换机与堆叠邻居的MAC地址大小来确定采用谁的选择，如以MAC地址小的交换机选择的链路所在端口为控制端口。当然，以MAC地址大小的判断也仅是一种实现方式，也可以通过其他如业务量大小等方式实现，在此不一一列举，可由工作人员根据需要进行提前的设置。
由上述内容可知，在堆叠邻居与本交换机连通的端口数目与协议控制链路需要数目相同时，就不存在链路分离的必要了，那么此时，步骤13还可以包括：
步骤137，在堆叠邻居的端口的数目为预设值时，选择所述端口作为协议控制端口以及数据转发端口。
由于堆叠邻居与本交换机连通的端口数目与协议控制链路需要数目相同，数据转发链路也就不得不与协议控制链路共用物理链路，因此，该些端口即是协议控制端口也是数据转发端口。
综上所述，本发明实施例的堆叠系统协议控制和转发链路分离的方法，通过了解堆叠邻居的端口的多种信息，在不增加配置难度基础上，以一定的条件自动分离协议控制链路和数据转发链路，实现协议控制链路和数据转发链路的去耦合，避免链路间的相互干扰。
