Description

配置方法、绑定方法、装置、设备、发送节点、接收节点及介质 技术领域
本申请涉及光纤通信，例如涉及一种配置方法、绑定方法、装置、设备、发送节点、接收节点及介质。
背景技术
光纤通信具有高带宽、传输距离远、低损耗等特性，已实现大规模部署，电层客户信号流，可以复用成光层信号进行传输。一个完全标准化的光传送单元-Cn(Completely Standardized Optical Transport Unit-Cn，OTUCn)信号可以分成多个灵活光传送网(Flexible Optical Transport Network，FlexO)物理通道，每个FlexO物理通道又可以分成多个子通道，每个子通道通过单独的一条光时隙交换(Optical Time Slot Interchanger，OTSi)信号传输，对应到单一的物理接口，且光传送网(Optical Transport Network，OTN)接口标准中所使用的OTSi信号的波长中心频率一样。但是，光媒质层复用标准并不涉及子通道以及子通道与物理接口的对应，光媒质层的头部开销信息组成方式并不适用于OTN接口标准定义的FlexO信号格式，无法区分不同的OTSi信号的分别封装，也无法提供足够的信息支持OTUCn信号的复用和解复用。由于无法有效配置光层通道的复用，无法准确的实现光通道的绑定或者创建光层路径，光层通道的复用可靠性低。

具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。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。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在客户信号映射到光媒质层传输的过程中，光媒质层复用标准并不涉及光层通道的子通道以及子通道与物理接口的对应，光媒质层的头部开销信息组成方式并不适用于OTN接口标准定义的FlexO信号格式，无法区分不同的OTSi信号分别封装，也无法提供足够的信息支持OTUCn信号的复用和解复用，因此，无法准确的实现光通道的绑定或者创建光层路径，使得光层通道的复用可靠性低。
在本申请实施例中，提供一种配置方法，可应用于网管设备、控制器等；目标节点例如为路由器、转换器、交换机等，目标节点在有开销通道的场景下可以是发送节点，在无开销通道的场景下可以是发送节点和接收节点。以下实施例以网管设备为例进行说明。网管设备通过为目标节点配置通道标识信息，实现光层通道的准确绑定，进而为客户信号的正确的复用和解复用提供基础。
图1为一实施例提供的一种配置方法的流程图，如图1所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，确定光层通道的复用结构。
本实施例中，网管设备根据光层通道的复用结构，可以确定光层通道的子通道以及子通道与物理接口之间的对应关系，据此配置通道标识信息，指示目标节点绑定光层通道，实现相应结构的光层通道的复用。
图2为一实施例提供的一种光层通道复用的示意图。如图2所示，电层客户信号流复用到光层信号以实现信号传递。单个的数字信息流，作为单一的客户，输入到数字通道/数字客户端(Digital-Lane/Digital-Client)适配模块，经过 适配模块的处理之后，输出了多条数字通道的信号OTSi，这些OTSi构成一个光支路信号组(Optical Tributary Signal Group，OTSiG)，每一个OTSi分别输入到每一个OTSi调制器；还输出了光支路信号组头部开销(Optical Tributary Signal Group–Overhead，OTSiG-O)，OTSiG-O中携带了OTSiG中包含的OTSi信号的组成信息。在此基础上，OTSiG与OTSiG-O组成了光支路信号集(Optical Tributary Signal Assembly，OTSiA)。每个客户信号例如光传送单元-Cn(OTUCn，Optical Transport Unit-Cn)信号，根据设备上实际接口的情况，可以分成m条FlexO物理通道，每个FlexO物理通道又进一步分成k条子物理通道，每条子物理通道分别调制到单独的一条OTSi信号来传输，每条OTSi占用单条光纤链路，也对应到单一的物理接口。
在步骤120中，根据所述复用结构为目标节点配置通道标识信息，所述通道标识信息用于指示所述目标节点绑定光层通道。
本实施例中，为目标节点配置通道标识信息，指示复用结构，为绑定光层通道和建立光层路径提供依据。配置的通道标识信息，可以通过光通信网络的头部开销传输，也可以通过集中式控制的南向接口协议下发，最终使得目标节点完成客户信号的复用和解复用。其中，在有开销通道的场景下，目标节点可以是指光通信网络中的发送节点，发送节点接收到通道标识信息后，一方面据此实现本地光层通道的绑定，另一方面还可以将通道标识信息发送至对应的远端的接收节点，以使接收节点也可以完成光层通道的绑定；在无开销通道的场景下，目标节点也可以包括光通信网络中的发送节点和接收节点，即，网管设备分别为发送节点和接收节点配置并下发通道标识信息，发送节点和接收节点分别基于网管设备下发的通道标识信息各自实现光层通道的绑定。
本实施例的配置方法，通过为目标节点配置通道标识信息，有效配置光层通道的复用，从而实现光层通道的准确绑定，进而为客户信号的正确的复用和解复用提供基础。
在一实施例中，目标节点包括发送节点；发送节点与对应的接收节点之间具有用于传输通道标识信息的开销通道。
本实施例是针对具有开销通道的场景。开销信号OTSiG-O是通过专门的开销通道来传输，开销信号中包括一个组成OTSiG的所有的OTSi信息，以及这些OTSi使用的通道信息，可继续使用以太网的光模块，其中每条OTSi占用单独的光纤链路，OTSi的发射机和接收机通常并不是可调的，使用固定频率的光信号，开销通道中可以使用通道标识信息来标识光信号。
图3为一实施例提供的一种在有开销通道场景下配置方法的实现示意图。如图3所示，目标节点为发送节点，网管设备配置的通道标识信息在开销通道 中传输至发送节点，发送节点一方面据此实现本地光层通道的绑定，另一方面还将通道标识信息发送至对应的远端的接收节点，以使接收节点也可以完成光层通道的绑定。
在一实施例中，通道标识信息包括发送节点的以下信息：光层适配接口本地标识符；光层包含的通道数目；通道本地标识符；通道包含的子通道数目；子通道本地标识符；子通道远端本地标识符。
本实施例中，在开销通道中，通过OTSiG-O携带组成OTSiG的通道以及子通道的物理接口的标识信息，并且对于子通道携带有本地标识符和远端本地标识符。接收节点在接收到开销通道中的头部开销后，根据其中携带的子通道的远端本地标识符，首先进行本地验证，在确认接收到的子通道远端本地标识符与本地标识符一致的情况下，进行本地的通道及子通道的绑定，并形成通道层面的接口地址和OTSiA层面的接口地址，从而创建光层路径，为信号的复用和解复用提供基础。
