Abstract

Description

交叉设置处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种交叉设置处理方法及装置。
背景技术
在传统光传送网中，业务交叉设置是通过管理平面或控制平面向网元下发命令，从而建立删除业务或对业务进行保护恢复。这种业务配置方式，已经越来越不能满足用户业务快速变化的需求。
软件定义网络(Software Defined Network，简称为SDN)的出现，可以有效利用全网的带宽资源，对网络资源进行快速配置，降低业务时延，确保业务路由和性能的可预测性。同时可以增加网络和业务配置的灵活性和弹性，实现带宽自动分配和实时调整。
目前在SDN中，对业务交叉设置普遍采用的方法是：上层控制器把每条单向的交叉设置命令封装到一条消息中，通过南向接口(上层控制器侧和下层控制器或网元之间的通讯接口)下发给下层控制器或网元，当所有需要设置的交叉设置命令都下发后，上层控制器会再发送一条确认请求消息给下层控制器或网元，通知下层控制器或网元这次交叉设置命令已经下发完毕。下层控制器或网元收到交叉设置消息后，会一一执行消息中的交叉设置命令，并通过北向接口(控制器或网元和上层控制器之间的通讯接口)向上层控制器发送应答消息，表示下层控制器或网元已经执行完所有交叉设置消息。
SDN中目前这种交叉设置方式，对单一的无保护恢复属性的业务的创建和删除操作，基本不会出现问题。但是当涉及到多条业务的创建删除或保护恢复操作时，在上层控制器和下层控制器或网元之间，会产生多条交互消息，当交互消息丢包，或者多个消息收发顺序不一致(特别是交叉设置消息晚于确认请求消息到达下层控制器或网元)时，业务的交叉设置就会出现错误，无法保证交叉设置的功能正确性和强壮性。而即使不发生丢包或消息收发错序的情况，多条消息的收发和确认应答消息的交互机制，对业务交叉设置的时间性能也存在极大的负面影响。
针对相关技术中多条业务交叉设置时导致交叉设置的可靠性低的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。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组合。
在本实施例中提供了一种交叉设置处理方法，图1是根据本发明实施例的交叉设置处理方法的流程图一，如图1所示，该流程包括如下步骤：
步骤S102，获取同一条业务的多条交叉设置命令；
步骤S104，将该多条交叉设置命令绑定在同一条交叉设置消息中；
步骤S106，将绑定后的该交叉设置消息下发给下层控制器或网元进行交叉设置处理。
通过上述步骤，获取同一条业务的多条交叉设置命令，将该多条交叉设置命令绑 定在同一条交叉设置消息中，将绑定后的该交叉设置消息下发给下层控制器或网元进行交叉设置处理，由于多个交叉设置命令是放置在一条交叉设置消息中，解决了相关技术中多条业务交叉设置时导致交叉设置的可靠性低的问题，从而在多条业务交叉设置时提高了交叉设置的可靠性。
在将绑定后的该交叉设置消息下发给下层控制器或网元进行交叉设置处理之后上层控制器可以根据下层控制器或网元执行该交叉设置消息的情况做相应的处理，在一个可选的实施例中，接收该下层控制器或该网元上报的成功消息，其中，该成功消息是该下层控制器或该网元执行该交叉设置消息中的该多条交叉设置命令成功后的发送的，保存该业务的交叉设置为成功状态，确保了交叉设置的功能正确性和强壮性。
在另一个可选的实施例中，接收该下层控制器或该网元上报的失败消息，其中，该失败消息是该下层控制器或该网元执行该交叉设置消息中的该多条交叉设置命令中的至少一条失败后发送的；根据该失败消息判断是否重新下发该交叉设置消息；在判断结果为是的情况下，重新下发该交叉设置消息。在判断结果为否的情况下，判断是否重新计算保护恢复路径；在判断结果为是的情况下，重新下发该交叉设置消息；在判断结果为否的情况下，保存该业务的交叉设置为失败状态。在下层控制器或网元执行交叉设置消息中的多条交叉设置命令中的至少一条失败的情况下，上层控制器根据该失败消息判断是重新下发该交叉设置消息还是保存该业务的交叉设置为失败状态，从而减短了对业务交叉设置的时间。
上述的多条交叉设置命令包括以下至少之一：双向交叉命令，保护交叉命令，恢复交叉命令。
上述的交叉设置消息包括以下至少之一：交叉设置类型，交叉源端口，业务信号类型，交叉宿端口。

步骤S204，根据该交叉设置消息进行交叉设置处理。
通过上述步骤，接收上层控制器下发的将多条交叉设置命令绑定在同一条交叉设置消息中的交叉设置消息，其中，该多条交叉设置命令为同一条业务的多条交叉设置命令；根据该交叉设置消息进行交叉设置处理，解决了相关技术中多条业务交叉设置时导致交叉设置的可靠性低的问题，从而在多条业务交叉设置时提高了交叉设置的可靠性。
在根据该交叉设置消息进行交叉设置处理之后，可以向上级上报对交叉设置消息中的多条交叉设置命令的执行结果，向该上层控制器上报执行该交叉设置消息中的该多条交叉设置命令成功的成功消息；或者，向该上层控制器上报执行该交叉设置消息中的该多条交叉设置命令中的至少一条失败的失败消息，需要说明的是，该成功消息是用于供上层控制器保存业务的交叉设置为成功状态的，该失败消息是用于供上层控制器根据该失败消息判断是重新下发该交叉设置消息还是保存该业务的交叉设置为失败状态，通过与上层控制器之间的信息交互，有效地缩减了对业务交叉设置的时间。
上述的多条交叉设置命令包括以下至少之一：双向交叉命令，保护交叉命令，恢复交叉命令。
上述的交叉设置消息包括以下至少之一：交叉设置类型，交叉源端口，业务信号类型，交叉宿端口。

下面结合可选实施例对本发明实施例进行进一步说明。
本可选实施例提供一种上层控制器将同一条业务的所有交叉设置相关的配置命令整合到一条消息中，通过南向接口下发给下层控制器或网元，并且不需要在上层控制器和下层控制器或网元间收发通知和应答消息，就能实现多业务交叉设置的方法，该方法适用于多条业务的创建删除和保护恢复的应用场景。具体包括以下内容：
上层控制器将同一条业务的多条交叉设置命令(双向交叉、保护交叉、恢复交叉)，以及相应的保护组信息，绑定在同一条交叉设置消息中(该消息中包括了交叉设置类型、交叉源端口、业务信号类型、交叉宿端口等信息。)，向下层控制器(或网元)下发该交叉设置消息。
下层控制器(或网元)在收到交叉设置消息后，分别执行消息中的多条命令，如果多条命令都执行成功，则向上层控制器回送执行成功消息；如果多条命令中有一条命令执行失败，则向上层控制器回送执行失败消息。
上层控制器收到交叉设置成功消息后，设置该业务为交叉设置成功状态；如果上层控制器收到的是交叉设置执行失败消息，则重新计算新的业务路径，再次下发业务的交叉设置，或设置该业务为交叉设置失败状态。
通过将同一条业务的多条交叉设置命令，以及保护组配置等设置信息，绑定在同一条交叉设置消息中，并通过南向接口下发到下层控制器或网元的方式，从而达到高效可靠地将多条业务分别进行交叉设置的目的，解决了目前SDN网络中多条业务交叉设置时，因为交互消息过多而可能存在的丢包、收发包顺序不一致等情况而造成的交叉设置的功能性和可靠性问题，以及由此引起的时间性能低下等问题。
图9是根据本发明实施例的软件定义网络的示意图，如图9所示，包括A、B、C、D四个网元和一个控制器。在网元A、B之间存在两条有保护有恢复的业务，工作路径都为A-B的直接连接，保护路径都为A-C-B，恢复路径都为A-D-B。
上层控制器是基于上述的网络拓扑结构将同一条业务的所有交叉设置相关的配置命令整合到一条交叉设置消息中，通过南向接口下发给下层控制器或网元，下层控制器或网元执行完该消息中的所有配置命令后，向上层控制器发送相应的成功或失败结果消息，不需要其它更多的通知和应答消息，就能实现多业务交叉设置的方法。
图10是根据本发明实施例的为多业务交叉设置的流程图，如图10所示，可以分为控制器下发交叉设置消息、网元执行交叉设置消息并上报执行结果给控制器、控制器根据执行结果决定是否重新处理三部分，具体包括以下步骤：
步骤S1002，上层控制器将一条业务的所有配置命令(包括工作路径交叉、保护路径交叉、恢复路径交叉、保护组配置信息)，按表1所示格式绑定为一条交叉设置消息；其中，OpType包括增加、删除交叉，以及保护组相关设置；InPort和OutPort包 括了该消息在网元的发送和接受命令的机架、子架、单板槽位、端口以及对应的波长和/或时隙序号，SignalType指该交叉设置命令的颗粒度。
表1
Figure PCTCN2015098089-appb-000001
步骤S1004，上层控制器向该业务的各条路径上的网元分别发送交叉设置消息；
步骤S1006，网元按收到的交叉设置消息的内容，进行交叉设置和保护组配置，各网元在收到一条交叉设置消息后，按消息内容进行交叉设置和保护组配置；
步骤S1008，向上层控制器上报交叉设置消息执行结果(成功或失败)，各网元在执行完一条交叉设置消息中的配置命令后，按执行结果向上层控制器上报交叉设置消息执行成功或失败消息；之后执行步骤S1012；
步骤S1010，判断是否所有业务交叉设置消息都已经下发完毕，在判断结果为是的情况下，执行步骤S1012，在判断结果为否的情况下，执行步骤S1002；
步骤S1012，等待网元上报交叉设置消息执行结果；
步骤S1014，判断收到上报的交叉设置消息执行结果为成功还是失败，在判断结果为成功的情况下，执行步骤S1016，在判断结果为失败的情况下，执行步骤S1018；
步骤S1016，保存该业务的交叉设置成功状态；上层控制器在收到网元上报的交叉设置消息执行成功消息后，保存该业务的成功状态或路径信息；
步骤S1018，判断是否直接重新下发交叉设置消息，在判断结果为是的情况下，执行步骤S1002，在判断结果为否的情况下，执行步骤S1020；上层控制器在收到网元上报的交叉设置消息执行失败消息后，分析失败原因，决定是重新下发交叉设置消息，还是重新计算业务路径，或者直接保存业务的失败状态。
步骤S1020，判断是否重新计算保护恢复路径，在判断结果为是的情况下，执行步骤S1002，在判断结果为否的情况下，执行步骤S1022；
步骤S1022，保存该业务的交叉设置失败状态。
在所有业务的交叉设置消息都已经处理完毕后，结束。
通过上述步骤，上层控制器把同一条业务的多条交叉设置命令，以及可能存在的保护组配置等设置信息，绑定在同一条交叉设置消息中，并通过南向接口下发到下层控制器或网元，网元执行完该消息中的所有设置命令后，向上层控制器回应一条成功或失败消息，就可以完成一条业务的配置，从而达到高效可靠地将多条业务分别进行交叉设置的目的，解决了目前SDN网络中多条业务交叉设置时，因为丢包、收发包顺序不一致等情况而造成的交叉设置的功能性和可靠性问题，交叉设置的时间性能也可以得到保证。
