技术领域
本申请涉及通信领域但不限于通信领域,具体而言,涉及时钟、时间同步方法、装置以及多路由器系统。
背景技术
随着通信网络高速发展,尤其是5G网络中,对大容量、低延时以及海量连接的需求越来越高,这个也让网络中对时钟和时间的同步需求越来越高。承载网络中,采用了集群、多虚一等方法集成多台设备,来解决单台设备无法满足容量和速度要求的问题。同时也增加了一个需求,就是在集群和多虚一设备中实现高精度时钟时间的同步。
传统的方法中,对于集群、多虚一设备采用单点接入时钟时间源,然后内部串行传递的方式来实现时钟时间的同步。这种方法带来了多台设备串行带来的精度大幅度下降的问题。其基本工作原理如下文描述。
图1是根据相关技术中时钟/时间同步的结构框图,如图1所示,时钟和时间从中心路由器输入,然后集群内部通过串行传递时钟来实现设备时钟和时间同步。当中心路由器发生变化时,时钟时间传递路径会从实线路径切换到虚线路径。
上述方式的缺点主要有:在复杂组网中,组网不够灵活,且硬性要求必须时钟输入口必须接入中心路由器;级联极大的降低了时钟、时间的精度无法满足新的高精度时钟的需求。以图1的2+8集群的设备为例,最大的引入了8级的误差,这个是无法满足高精度时钟对单节点设备的精度需 求。
针对相关技术中从中心路由器的端口输入时钟/时间,之后实现时钟/或时间同步,组网不够灵活且无法满足时钟/时间的高精度需求的问题,尚未提出解决方案。

本申请提出的多路由器系统中时钟、时间同步的方法,该方法和系统克服了现有技术中存在的组网不够灵活以的问题,实现了集群、多虚一内部时钟接口可以灵活从路由器引入,同时能够满足高精度时钟精度这一需求。时钟同步实现方法如下:
步骤1:时钟同步的上送,图10是根据本申请实施例的时钟同步方法的设备模块连接示意图,如图10所示,主路由器检测到时钟的输入口在路由器1上,则通知该路由器,由路由器上的时钟子卡同步时钟。路由器再通过面板时钟口传递时钟给主中心路由器同步,上送到备中心路由器进行备份;主路由器通知主中心路由器从该路由器同步,之后由主中心路由器的时钟分发板把时钟传递给备中心路由器以及剩余的路由器。
步骤2:在步骤1的基础上,此时如果时钟源发生了切换,即时钟输入的端口发生了改变,主路由器通知路由器1进入hold over保持模式。如果切换后时钟的输入口在同一框上,则上送下发路径不变,路由器1自行切换到另一个端口进行同步,再在锁定后上送时钟给主中心路由器,主路由器通知主中心路由器进行同步并分发。
步骤3:在步骤2的基础上,如果时钟源切换到另外的路由器上,例如,从路由器1切换到路由器2,主路由器通知路由器1进入hold over模式,进一步的,通知主中心路由器停止从路由器1提取时钟,通知路由器2从对应的端口提取时钟。路由器2时钟同步完成后,主路由器再通知主中心路由器从路由器2提取时钟,完成时钟同步并分发;
步骤4:在步骤3的基础上,路由器1,从hold over模式切换到主中心路由器下发时钟同步,其他路由器同步方式不变。
步骤5:在步骤1的基础上,如果主路由器检测到主中心路由器发生了变化,通知备中心路由器同步时钟,由备中心路由器同步路由器1上送的时钟,进而分发给各个路由器进行同步,如图10中的虚线流程。
时间同步实现方法包括以下步骤:
步骤1:对于时间同步,图11是根据本申请实施例的GPS或北斗时间同步时的设备模块连接示意图,如图11所示,此时集群里面设备分为,主中心路由器、备中心路由器、主路由器以及路由器;
步骤2:在步骤1的基础上,如果此时集群的时间注入方式是通过GPS或北斗时间同步,那么在接入GPS或北斗的路由器上,将GPS或北斗时间同步到本地,再通过面板时钟口把时间传递到主中心路由器和备中心路由器,其中备中心路由器用于备份。主中心路由器同步这个时间后,通过时钟分发板,把时间分发给备中心路由器和其他的路由器上去,实现时间同步。
步骤3:在步骤2的基础上,如果此时主路由器检测到GPS或北斗时钟发生了源切换,通过计算确定切换的时间源在原来的路由器上,通知该路由器时间源发生切换,路由器接收到通知之后自行发生源切换,从切换后的端口提取时间并同步。如果此时GPS或北斗时钟源切换到其他路由器上,那么此时主路由器通知路由器1停止从GPS或北斗口提取时钟,并通知主中心路由器选择路由器2上送的时间。主中心路由器同步这个时间后,通过时钟分发板,把时间分发备中心路由器和其他的路由器上去,实现时间同步。
