本发明的实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
本发明针对相关技术中发送端和接收端的时钟时间传送模式不一致,导致接收端无法编译发送端发送的时钟时间信息,从而使得时钟时间信息传送中断的问题,提供了一种光传送网络中时钟时间传送模式同步的方法及装置,能够实现接收端与发送端时钟时间传送模式的同步,确保两端时钟时间信号的正确传输,提高信号传输的效率及稳定性。
如图1所示,为本发明实施例时钟时间传送模式同步系统示意图:
时钟时间传送模式同步系统结构分为发送端的时钟时间处理系统和接收端的时钟时间处理系统。其中,发送端时钟时间处理系统包括:发送端控 制单元、告警接收单元、发送端光传送网处理单元;接收端时钟时间处理系统包括:接收端光传送网处理单元、接收端时钟时间传送工作模式编码提取单元、时钟时间传送模式校验单元、时钟时间告警检测单元以及接收端控制单元。
接收端时钟时间处理系统中时钟时间传送模式校验单元连接至接收端时钟时间传送工作模式编码提取单元和时钟时间告警检测单元,判断是否支持发送端的时钟时间传送模式;时钟时间告警检测单元连接至时钟时间传送模式校验单元,判断结果为不支持的情况下发送相应告警给接收端控制单元;接收端控制单元根据相应告警反馈给接收端光传送网处理单元,接收端光传送网处理单元与发送端光传送网处理单元连接,并通过发送端光传送网处理单元将告警发送给告警接收单元,进而上报给发送端控制单元,发送端控制单元根据相应告警更改时钟时间传送模式,发送给发送端光传送网处理单元,用于发送时钟时间传送模式,实现最终的时钟时间模式同步。
如图2所示,本发明实施例提供一种光传送网络中时钟时间传送模式同步的方法,应用于发送端,本发明实施例方法包括:
步骤101、当时钟时间节点存在时钟时间同步中断告警时,将当前使用的时钟时间传送模式发送至接收端,由接收端根据接收到的时钟时间传送模式更新接收端本地当前时钟时间节点的时钟时间传送模式;
步骤102、接收接收端反馈的时钟时间传送模式应答,完成与接收端时钟时间传送模式的同步。
可选的,光传送网络定时轮询检测当前时钟时间节点是否有时钟时间同步中断告警,当检测到时钟时间同步中断告警时,发送端将当前使用的时钟时间传送模式发送至接收端,使得接收端根据接收到的时钟时间传送模式更新本地当前时钟时间节点的时钟时间传送模式。发送端在等待接收端完成本地当前时钟时间节点的时钟时间传送模式的更新后,接收接收端反馈的时钟时间传送模式应答,完成发送端与接收端时钟时间传送模式的同步。
通过将发送端当前使用的时钟时间传送模式发送至接收端,使得接收端根据接收到的时钟时间传送模式来调整本地使用的时钟时间传送模式,解决了发送端和接收端的时钟时间传送模式不同步的问题,在实现发送端与接收 端时钟时间传送模式同步的基础上,实现了发送端和接收端时钟时间信号的正确传输,提高了信号传输的效率及稳定性。
在本发明上述实施例中,步骤101中将当前使用的时钟时间传送模式发送至接收端,包括:
步骤1011、在时钟时间传送工作模式列表中查询获得与当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码,其中,时钟时间传送工作模式列表中记录有为每一种时钟时间传送模式配置的时钟时间传送工作模式编码;
步骤1012、将查询获得的时钟时间传送工作模式编码插入光传送网信号的开销保留字节,将光传送网信号发送至接收端。
可选的,预先统计发送端支持的每一个时钟时间传送模式,按预设的编码方式为每一种时钟时间传送模式分配一个唯一的时钟时间传送工作模式编码,形成时钟时间传送工作模式列表,根据时钟时间传送工作模式列表可以获取与每一种时钟时间传送模式匹配的时钟时间传送工作模式编码。
需要说明的是,光传送网中的业务信号以及非业务信号均以帧结构的形式进行传输,并定义了丰富的开销字节,为了不影响业务的正常传送,时钟时间传送模式使用的开销可以采用G.709规定的保留开销,进行通道线路中时钟时间模式的传送。
在获取与当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码后,将时钟时间传送工作模式编码插入光传送网信号的开销保留字节,将光传送网信号发送至接收端。
如图3所示,发送端时钟时间传送处理单元在控制单元的控制下选择一种时钟时间传送模式,并将时钟时间传送工作模式编码插入一光传送网开销保留字节中,然后将光传送网信号传送给接收端时钟时间传送处理单元,接收端时钟时间处理单元接收到光传送网信号之后,从开销保留字节中取出时钟时间传送工作模式编码。
可选的,在本发明上述实施例中,步骤101中将当前使用的时钟时间传送模式发送至接收端,包括:
将与当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码插入监控信号中,并将监控信号和光传送网信号合成光信号发送至接收端。
可选的,在时钟时间传送工作模式列表中查询获得与当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码,将时钟时间传送工作模式编码插入监控信号中,由于监控信号以帧结构的形式进行传输,将时钟时间传送工作模式编码插入监控信号所在的帧时,可以选择帧的特定位置以便定位,例如,帧头或帧尾。将包含时钟时间传送工作模式编码的监控信号和要发送的光传送网信号合成光信号并发送至接收端。监控信号在传送模式中起到监控的作用,将时钟时间传送工作模式编码插入监控信号中,与将时钟时间传送工作模式编码插入光传送网信号中相比,可以保证光传送网信号传送较多的业务。
如图4所示,发送端控制单元选择时钟时间传送模式发送给发送端光传送网处理单元,将所选择的时钟时间传送工作模式编码发送给发送端监控处理单元。发送端光传送网处理单元根据接收的时钟时间传送模式向发送端光传送网信号与监控信号处理器发送相应的光传送网信号;发送端监控处理单元接收发送端控制单元发送的时钟时间传送工作模式编码后,将接收的时钟时间传送工作模式编码插入监控信号所在的帧,将包含时钟时间传送工作模式编码的监控信号发送给发送端光传送网信号与监控信号处理器;发送端光传送网信号与监控信号处理器,将要发送的光传送网信号以及监控信号合成光信号并发送。
在本发明上述实施例中,在将当前使用的时钟时间传送模式发送至接收端之后,接收接收端反馈的时钟时间传送模式应答之前,本发明实施例方法还包括:接收接收端发送的时钟时间传送模式校验成功消息,向接收端发送确认消息,由接收端根据确认消息,更新本地当前时钟时间节点的时钟时间传送模式。
可选的,如图5所示,在将当前使用的时钟时间传送模式发送至接收端之后,还需要接收接收端反馈的时钟时间传送模式校验成功消息,发送端对校验成功消息进行确认后,将确认消息发送至接收端,使得接收端根据确认消息更新接收端本地当前时钟时间节点的时钟时间传送模式。
本发明实施例还提供一种计算机存储介质,计算机存储介质中存储有计算机可执行指令,计算机可执行指令用于执行上述光传送网络中时钟时间传送模式同步的方法。
本发明实施例提供一种光传送网络中时钟时间传送模式同步的方法,应用于接收端,如图6所示,包括:
步骤201、接收发送端发送的与发送端当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码,根据时钟时间传送工作模式编码获取发送端当前使用的时钟时间传送模式;
步骤202、若支持接收到的时钟时间传送模式编码,判断当前时钟时间传送模式与获取的时钟时间传送模式是否一致;
步骤203、如果不一致,则按照获取的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式,并在更新完成后向发送端反馈时钟时间传送模式应答。
可选的,在接收到发送端发送的时钟时间传送工作模式编码后,即可获取相应的发送端当前使用的时钟时间传送模式,判断接收端是否支持接收到的时钟时间传送工作模式编码,如果不支持,则提示告警信息。在判断时,将获取的时钟时间传送工作模式编码同本地保存的时钟时间传送工作模式编码列表中的任意一个编码进行比较,当获取的时钟时间传送工作模式编码同本地保存的时钟时间传送工作模式编码列表中的任意一个编码均不相符,表明接收端不支持接收到的时钟时间传送工作模式编码。然后接收发送端发送的下一时钟时间传送工作模式编码。
可选的,在本发明上述实施例中,步骤201包括:
接收发送端发送的携带时钟时间传送工作模式编码的光传送网信号,其中,时钟时间传送工作模式编码存储在光传送网信号的开销保留字节中。
可选的,如图3所示,接收端时钟时间传送处理单元接收携带时钟时间传送工作模式编码的光传送网信号后,在光传送网信号的开销保留字节中提 取时钟时间传送工作模式编码,根据时钟时间传送工作模式编码即可获取相应的时钟时间传送模式。
在本发明上述实施例中,步骤201包括:
步骤2011、接收发送端发送的携带时钟时间传送工作模式编码的光信号;
步骤2012、根据波长的不同,将光信号分解成光传送网信号和监控信号,其中,监控信号中携带有时钟时间传送工作模式编码;
需要说明的是,接收端进行光信号分析时,根据自身波长进行分解,波长大小的确定为本领域技术人员的公知常识。
步骤2013、将监控信号中携带的时钟时间传送工作模式编码发送至光传送网信号中。
可选的,接收携带时钟时间传送工作模式编码的光信号,并按照波长的不同,将光信号分解成光传送网信号和监控信号,其中,光传送网信号用于业务的传输,监控信号中携带有时钟时间传送工作模式编码,在接收到监控信号后,将时钟时间传送工作模式编码发送至光传送网信号,保证光传送网信号在由发送端到接收端的过程中,可以传送较多的业务。
如图4所示,接收端光传送网信号与监控信号处理器将接收的光信号根据波长的不同,分解成光传送网信号以及监控信号,将光传送网信号发送至接收端光传送网处理单元,将监控信号发送至接收端监控处理单元;接收端光传送网处理单元,接收光传送网信号,并根据接收端控制单元发送的时钟时间传送工作模式编码调整时钟时间传送模式;接收端监控处理单元,接收监控信号后,根据时钟时间传送工作模式编码在监控信号中的位置,提取监控信号中的时钟时间传送工作模式编码发送给接收端控制单元;接收端控制单元,接收接收端监控处理单元发送的时钟时间传送工作模式编码,将获取的时钟时间传送工作模式编码发送给接收端光传送网处理单元。接收端控制单元,向接收端监控处理单元发送告警信息,接收端监控处理单元,将告警信息插入监控信号将包含告警信息的监控信号通过接收端光传送网信号与监控信号处理器发送至发送端。
可选的,在本发明上述实施例中,按照获取的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式之前,本发明实施例方法还包括:
当获取的时钟时间传送模式可用且与当前时钟时间节点的时钟时间传送模式不一致时,向发送端发送校验成功消息,并接收发送端返回的确认消息。
需要说明的是,可用可以理解为有效,判断获取的时钟时间传送模式是否可用可以通过相关技术中的参照列表进行对比获得,为本领域技术人员的惯用技术手段。
可选的,在接收到发送端发送的与发送端当前使用的时钟时间传送模式匹配的时钟时间传送工作模式编码后,根据时钟时间传送工作模式编码即可获取相应的时钟时间传送模式。判断接收端是否支持时钟时间传送工作模式编码,当接收端支持时钟时间传送工作模式编码时,表明时钟时间传送工作模式可用。需要继续判断当前时钟时间传送模式与获取的时钟时间传送模式是否一致,在判断时,将接收的时钟时间传送工作模式编码同本地保存的时钟时间传送工作模式编码列表比较,确定同其中一个相符,同当前使用的时钟时间传送工作模式编码进行比较,确定两者不同,表明当前时钟时间传送模式与接收到的时钟时间传送模式不一致。
在此情况下,如图5所示,向发送端发送校验成功消息,并接收发送端返回的确认消息。根据确认成功消息,按照接收到的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式,这种方式安全性与稳定性比较好。
需要说明的是,如图7所示,发送端与接收端之间时钟时间传送模式同步过程中,接收端在判断时钟时间传送模式可用后,且当前时钟时间传送模式与获取的时钟时间传送模式不一致时,无需发送校验成功消息,即可按照获取的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式,这种方式执行效率比较高。
本发明实施例还提供一种计算机存储介质,计算机存储介质中存储有计算机可执行指令,计算机可执行指令用于执行上述光传送网络中时钟时间传 送模式同步的方法。

    更新应答模块设置为,当当前时钟时间传送模式与获取的时钟时间传送模式不一致时,则按照获取的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式,并在更新完成后向所述发送端反馈时钟时间传送模式应答。
  14. 如权利要求13所述的装置,所述第二接收模块还设置为:
    接收所述发送端发送的携带所述时钟时间传送工作模式编码的光传送网信号,其中,所述时钟时间传送工作模式编码存储在所述光传送网信号的开销保留字节中。
  15. 如权利要求13所述的装置,其中,所述第二接收模块包括:
    接收子模块设置为,接收发送端发送的携带所述时钟时间传送工作模式编码的光信号;
    分解子模块设置为,根据波长的不同,将所述光信号分解成光传送网信号和监控信号,其中,所述监控信号中携带有所述时钟时间传送工作模式编码;
    发送子模块设置为,将所述监控信号中携带的所述时钟时间传送工作模式编码发送至所述光传送网信号中。
  16. 如权利要求13所述的装置,所述装置还包括:
    第二处理模块,设置为在所述更新应答模块按照获取的时钟时间传送模式更新当前时钟时间节点的时钟时间传送模式之前,当获取的时钟时间传送模式可用且与当前时钟时间节点的时钟时间传送模式不一致时,向所述发送 端发送校验成功消息,并接收所述发送端返回的确认消息。
