可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为了更好的理解本公开，以下结合具体的实施例对本公开做进一步解释。
本公开优选实施例的目的是提出在一种根据LACP协议报文特征，通过在协议交互过程中交互时戳信息，达到交互双方真正同步聚合的目的，减少对工程业务的影响。
在本发明本公开优选实施例中，利用网络时间协议(Network Time Protocol，简称NTP)进行协议交互思想，主要使用相关在LACP协议数据单元(Protocol Data Unit，简称PDU)中携带的交互双方的时间信息，达到获取双方时间的目的。具体地说，在LACP初始化阶段，交互双方在发出初始化报文时，在LACP保留字段开始的4字节都是T1，第二个4字节为 T2，第三个4字节为T3，第4个4字节为T4。在发送第一个初始化报文时，T1填上本端的高精度时戳，对端收到时候在T2上面填上对端时戳。在对端回复时，在T3填上对端的时戳，本端收到对端报文的时候在T4上面填上，这样，双方的时延就是delay等于(T2-T1)+(T4-T3)，单向报文时延就是该delay的一半。LACP的聚合不在简单的只根据收到对端syn报文后就可以聚合，而是要判断主从端，通过对LACP里面系统标识，系统ID较小的为主端，从端要收到主端的聚合报文后才能开始聚合。主端根据之前报文计算delay时间，给出一个聚合时间T5，放到第5个4字节中，从端根据之前T3和T4可以知道本端与主端的时间差异，换算T5到本端时间，双方按照该时间点最终设置系统的聚合。由此，双方系统达到了同一个时间点聚合。
在实际使用中，可以将本公开的实施例提供的方法应用于宽带接入设备，以有效实现了聚合组的负荷均衡。对于不同组网情况下的负荷分担情况均优于之前的固定方式，同时系统能够稳定在1ms以内。
图5是根据本公开实施例提供的LACP报文保留字段示意图。如图5所示，LACP报文长度一般是128，除了正常标准规定的字段外，最后还有50字节的保留字段。对于非0的保留字段，正常协议也是能够处理的。也就是说，即使不支持新方法的设备，对接也不存在问题。
图6是根据本公开实施例提供的LACP报文交互的示意图。如图6所示，设备A和设备B开始双方开始进行LACP交互。设备A和设备B第一次都会主动发送第一个初始化报文，告诉对方自己相关状态。在该报文中，两个T1字段都被写入了本地时戳。双方收到报文后，将收到的报文时间写入到T2中。若LACP标准流程决策可以进入下一个状态，则会将本端的syn位置位并发送给对方。在将本端的syn位发送给对方前，会将上次收到的对端信息打包到报文中，同时还需要把之前报文收到的T1,T2也拷贝到报文中，并在发送时将T3置位。该syn报文被对端收到后，T4的时间也被记录。最终，若设备A的系统ID小于设备B的系统ID，则设备A’会在最终的聚合报文中带上T5。T5是相对于设备A当前时间的时戳，在设备B收到后，根据之前T1-T4，将T5转换为设备B的时戳，最后端口到该时间时候执行 端口实际聚合。
显然，本领域的技术人员应该明白，上述的本公开的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本公开不限制于任何特定的硬件和软件结合。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
