Description

一种生成波长路由网络拓扑方法和装置 技术领域
本申请涉及通信领域，尤其涉及一种生成波长路由网络拓扑方法和装置。
背景技术
随着用户对网络带宽需求的不断增长，光网络将在未来发挥越来越重要的作用。要更高效更直观地管理光网络业务，光网络拓扑可视化成为重要需求。目前，网络的逻辑拓扑可以根据网络规划和逻辑配置得到，网络结点拓扑可以根据数据通信网络(Data Communication Network，DCN)路由得到，而对于业务层的光波长路由物理拓扑目前还没有很好的方法快速获取。
现有技术一是基于逻辑配置生成网络波长拓扑信息，根据规划的业务配置自动获取网络波长拓扑图，默认物理波长拓扑与逻辑拓扑一致，可以快速简单获取。现有技术二是通过在现网中运行网络拓扑协议来获取网络拓扑。通过网络监控管理通信通道，运行开放式最短路径优先(Open Shortest Path First，OSPF)或邻居拓扑发现协议(Neighbor Topology Discovery Protocol，NTDP)等协议，生成网络结点拓扑，再结合网元(Network Element，NE)信息生成网络逻辑。
现有技术一中，由于在实际网络运营过程中，业务会发生变化，此时可能与前期规划不同，用户规划的业务无法真实反映现网中的实际组网信息，也就是物理组网和逻辑配置都可能存在差异。现有技术二需要在网络中发送洪泛信息，对网络组网规模有约束。
发明内容
本申请实施例提供一种生成波长路由网络拓扑方法和装置，能够解决物理波长拓扑与根据逻辑配置生成的网络拓扑存在差异以及发送洪泛信息对网络组网规模有约束的问题。
一方面，提供一种生成波长路由网络拓扑方法，包括：第一网元接收第二网元发送的波长信息的集合，每个波长信息包括波长经过的跨段计 数、第二网元的发送端口以及波长的标识；第一网元确定每个波长的标识对应的波长是否经过第一网元；对于每个波长信息，若确定该波长信息对应的波长经过第一网元，则第一网元更新该波长的跨段计数；第一网元向未接收到该波长信息的端口对应的下一网元发送更新后的该波长信息，更新后的该波长信息包括更新后的跨段计数、第一网元的发送端口以及波长的标识，并向网络管理设备发送更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识，以便网络管理设备根据接收到的各个网元的更新后的波长信息以及波长的接收端口获取波长的路由网络拓扑。这样一来，对于每个波长信息，当第一网元确定该波长信息对应的波长经过第一网元时，第一网元更新该波长的跨段计数和发送端口，并将更新后的该波长信息向未接收到该波长信息的端口对应的下一网元发送，相比现有技术，网元向所连接的任一网元发送洪泛信息，本申请实施例可通过网元邻居间简单交互，即发送更新后的波长信息是有限次的，不需要发送洪泛信息，能够解决洪泛信息对网络组网规模有约束的问题。并且，第一网元可以将更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识保存在本网元，当网络管理设备需要生成波长的路由网络拓扑时，各网元可以向网络管理设备发送跨段计数、发送端口、接收端口以及波长的标识以便于网络管理设备生成波长的路由网络拓扑，相比现有技术根据逻辑配置生成的网络拓扑导致物理波长拓扑与生成的网络拓扑存在差异，本申请实施例是网络管理设备根据各网元中相同波长的跨段计数、发送端口、接收端口以及波长的标识生成路由网络拓扑，而不是根据逻辑配置生成的网络拓扑，能够解决物理波长拓扑与根据逻辑配置生成的网络拓扑存在差异的问题。

在一种可能的设计中，方法还包括:第一网元保存更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识。这样一来，当网络管理设备需要获取波长的路由网络拓扑时，可以根据各网元保存的更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识，获取波长的路由网络拓扑。

具体实施方式
本申请实施例可应用于光网络中生成光波长路由网络拓扑的场景。如图1所示，本申请实施例的网络架构可以包括网络管理设备和至少两个网元，以第一网元和第二网元为例，第一网元和第二网元可以组成一个用于生成光波长路由网络拓扑的光网络。第一网元可以用于接收第二网元发送的波长信息的集合。第二网元可以用于向第一网元发送波长信息的集合。本申请实施例的网络架构还可以包括第三网元，第三网元可以用于接收第一网元发送的更新后的波长信息。其中，第一网元、第二网元和第三网元可以为波分网元。网络管理设备可以是软件定义网络(Software Defined Network,SDN)控制器，可以运行在独立的服务器上，并通过以太网线直连或第三方网络连接至少两个网元中的每个网元来管理整个光网络。在本申请实施例中，SDN控制器可以实时查看网络的光波长路由网络拓扑，以便于提升网络运维的效率和可视化带来的便利。
在本申请中，第一网元可以包括光电转换和波长调度两大功能，第一网元在硬件部署上可以有多种方式，本申请不限定第一网元的硬件部署方式。在实际组网中，可以将第一网元分为电网元和光网元，换句话说，第一网元可以是电网元，也可以是光网元。电网元的内部结构示意图如图2a所示，可以由系统控制单元、光电转换单元、波长信息写入和提取单元组成。其中，电网元中的波长信息写入和提取单元的波长写入过程，可以是在光电转换单元将业务信息转换成标准波长进入波分系统之前完成；波长提取过程，可以是在光电转换单元将波分系统输出的标准波长转换成 业务信息之前完成。光网元的内部结构示意图如图2b所示，可以由系统控制单元、波分调度单元、波长监控单元和光监控通信单元组成。光网元的波长监控单元可以对每个主线路维度都支持。
图3为本申请的网络管理设备的一种内部结构示意图，在本申请中，网络管理设备可以包括处理模块301、通讯模块303和存储模块303。其中，处理模块301用于控制网络管理设备的各部分硬件装置和应用程序软件等；通讯模块303用于可使用蜂窝、以太网、和红外等通讯方式接受其它设备发送的指令，也可以将网络管理设备的数据发送给云端或其它设备；存储模块303用于执行网络管理设备的软件程序的存储、数据的存储和软件的运行等，可以是随机存取存储器、可擦除可编程只读寄存器、固态硬盘和SD卡(Secure Digital Memory Card)等中的一种或多种。
本申请实施例提供一种生成光波长路由网络拓扑方法，其大致过程为，第一网元接收第二网元发送的波长信息的集合，波长可以为光波长，并确定波长信息的集合中的每个波长信息对应的波长是否经过第一网元；若确定该波长信息对应的波长经过第一网元，则第一网元更新该波长的跨段计数；然后，第一网元向未接收到该波长信息的端口(port)对应的下一网元发送更新后的该波长信息，未接收到该波长信息的端口是指第一网元上接收到该波长信息的端口以外的端口，下一网元可以继续执行类似第一网元执行的动作。当网络管理设备需要获取波长的路由网络拓扑时，网络管理设备可以根据每个网元发送的更新后的该波长信息以及该网元接收到该波长的接收端口，以获取波长的路由网络拓扑。
本申请实施例提供一种生成光波长路由网络拓扑方法，如图4所示，包括：
401、第二网元向第一网元发送的波长信息的集合，每个波长信息包括波长经过的跨段计数、第二网元的发送端口以及波长的标识。
第一网元可以通过光监控通信单元接收第二网元发送的波长信息的集合。
举例来说，记为举例1，如图5所示，假设图5为一个简单的光网络，该光网络包括8个网元，分被为NE1、NE2、NE3、NE4、NE5、NE6、 NE7和NE8，设定第一网元为NE3，第二网元为NE1，NE3接收到NE1发送的波长信息的集合为：{NE1-λ1～NE1-端口1～0，NE1-λ2～NE1-端口1～0}。波长信息的集合中包括波长λ1和波长λ2的波长信息，各波长信息的跨段计数、第二网元的发送端口和波长的标识可以用符号“～”或“，”隔开；其中，NE1-λ1的波长经过的跨段计数为0，NE1的发送端口为NE1-端口1，波长的标识为NE1-λ1；NE1-λ2的波长经过的跨段计数为0，NE1的发送端口NE1-端口1，波长的标识为NE1-λ2。
需要说明的是，初始网元发送的波长信息中的跨段计数为初始值，例如为0。初始网元是产生波长的网元。假设跨段计数的初始值为0，按照上述举例，则第二网元NE1为初始网元，第一网元NE3接收到的波长信息的集合是初始网元发送的。
402、第一网元确定经过第一网元的波长的集合；并根据波长的集合以及波长信息的集合的交集确定波长信息的集合中每个波长的标识对应的波长是否经过第一网元。
波长的集合是指初始网元的光电转换单元将业务信息转换成的标准波长的集合，波长的集合可以包括波长产生的槽位号和光口号和波长等信息，波长的集合可以基于业务波长随路开销传输，因此第一网元可以通过波长监控单元或随路开销接收装置检测经过第一网元的波长的集合。需要说明的是，波长的集合在传输过程中是不变的，直至波长的集合中的波长到达目的网元时，目的网元中的光电转换单元可以将波长转换为业务信息，目的网元可以理解为能够将波长集合中的波长转换为业务信息的网元。
当第一网元确定波长的集合以及波长信息的集合的交集时，是根据第一网元的同一个端口接收到的波长的集合和波长信息的集合来确定交集的。
根据步骤401中的举例1，若NE3接收到NE1发送的波长信息的集合是由NE3的端口1接收的。NE3检测到经过第一网元的波长的集合为{NE1-λ1}，且{NE1-λ1}也是由NE3的端口1接收的，那么NE3根据波长的集合和波长信息的集合得到交集为：NE1-λ1；则NE3可以确定波长 的标识NE1-λ1对应的波长经过第一网元。
类似地，举例2为：如图5所示，假设第一网元为NE5，第二网元为NE1，NE5从NE5的端口1接收到的波长的集合为：{NE1-λ2}，从,端口1接收到的波长信息的集合为：{NE1-λ1～NE1-端口2～0，NE1-λ2～NE1-端口2～0}，则根据上述波长的集合和波长信息的集合得到交集为：NE1-λ2；则NE5可以确定波长的标识NE1-λ2对应的波长经过第一网元。
另外，若第一网元确定波长信息的集合中的任一波长信息对应的波长不经过第一网元，则第一网元将该波长信息丢弃。
参照步骤401的举例1，假设当NE3接收到的波长的集合为：{NE1-λ1}，则NE3可以确定波长信息的集合中的波长信息{NE1-λ2～NE1-端口1～0}对应的波长NE1-λ2不经过第一网元，则NE3将{NE1-λ2～NE1-端口1～0}丢弃。
可以理解的是，步骤401和步骤402可以同时进行。
403、对于每个波长信息，若确定该波长信息对应的波长经过第一网元，则第一网元向未接收到该波长信息的端口对应的下一网元发送更新后的该波长信息，更新后的该波长信息包括更新后的跨段计数、第一网元的发送端口以及波长的标识。
其中，下一网元可以有多个，本申请实施例以下一网元为第三网元为例进行说明。第一网元更新波长的跨段计数可以是第一网元将该波长的跨段计数累加预设值，预设值可以为正整数，例如为1。
参照步骤401的举例1，假设预设值为1，NE3从NE1接收到的波长的集合为：{NE1-λ1}，若NE3确定出的经过NE3的波长为NE1-λ1对应的波长；则NE3将NE1-λ1的波长信息中的跨段计数0累计1，即将跨段计数更新为1，并将发送端口NE1-端口1更新为NE3的发送端口，即NE3待发送该更新后的波长信息的端口。
第一网元的发送更新后的波长信息的端口与接收波长信息的端口是不同的。参照步骤401的举例1，假设NE3有两个端口，分别为端口1 和端口2，接收{NE1-λ1～NE1-端口1～0}的端口为端口1，则NE3发送更新后的该波长信息的端口不能为端口1，NE3可以将{NE1-λ1～NE1-端口1～0}更新为{NE1-λ1～NE3-端口2～1}后通过端口2发送NE6。
类似的，参考举例2，假设NE5由3个端口，当NE5上待发送更新的波长信息的端口为端口2，跨段计数的预设值为1时，NE5将波长信息更新为{NE1-λ2～NE5-端口2～1}，当NE5上待发送更新的波长信息的端口为端口3，跨段计数的预设值为1时，NE5将波长信息更新为{NE1-λ2～NE5-端口3～1}，当然，NE5可以同时通过端口2和端口3发送更新后的波长信息。
类似的，如图5所示，当NE6或NE2为第一网元时，执行与NE3相同的步骤。
404、对于每个波长信息，若确定该波长信息对应的波长经过第一网元，则第一网元在网络管理设备需要获取波长的网络路由拓扑时向网络管理设备发送更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识。
对于每个波长信息，若确定该波长信息对应的波长经过第一网元，则第一网元可以保存更新后的跨段计数、第二网元的发送端口、第一网元接收到该波长的接收端口以及波长的标识，保存的格式可以为：{波长的标识～源发送端口指示～宿接收端口指示～跨段计数}。其中，源发送端口指示用于指示第二网元的发送端口，宿接收端口指示用于指示第一网元接收该波长信息的端口。
参考举例2，若NE5确定出的经过NE5的波长为：NE1-λ2，当预设值为1时，则NE5可以将NE1-λ2对应的{NE1-λ2～NE1-端口2～0}中的跨段计数从0更新为1，并将更新了跨段计数的波长信息和NE5接收到NE1-λ2的端口“NE5-端口1”保存到NE5中。
当网络管理设备需要生成任一经过第一网元的波长的路由网络拓扑时，第一网元可以将第一网元中保存的更新了跨段计数的该波长信息以及第一网元接收到该波长的接收端口发送给网络管理设备。
另外，初始网元保存的{波长的标识～源发送端口指示～宿接收端口指 示～跨段计数}中，源发送端口指示和宿接收端口指示可以是相同的，例如图5中，NE1中保存的{波长的标识～源发送端口指示～宿接收端口指示～跨段计数}为{NE1-λ1～NE1-端口1～NE1-端口1～0，NE1-λ2～NE1-端口2～NE1-端口2～0}。
405、网络管理设备根据至少一个网元发送的同一波长的波长信息以及该波长的接收端口生成同一波长的路由网络拓扑。
可以理解的是，网络管理设备在生成任一波长的路由网络拓扑时，可以接收多个网元发送的更新后的跨段计数、发送端口、接收端口以及波长的标识。多个网元中的每一个网元都可以执行本实施例中第一网元的步骤。
网络管理设备可以根据多个网元发送的波长信息中的同一波长的标识对应的网元的发送端口和网元的接收端口按照同一波长的标识对应的跨段计数顺次连接，得到同一波长的路由网络拓扑。
举例来说，如图5所示，当网络管理设备需要得到NE1-λ1路由网络拓扑时，假设NE1-λ1经过了NE1、NE3、NE6和NE2，且NE1、NE3、NE6和NE2保存的跨段计数、发送端口、接收端口以及波长的标识分别为{NE1-λ1～NE1-端口1～0}，{NE1-λ1～NE1-端口1～1～NE3-端口1}，{NE1-λ1～NE3-端口2～2～NE6-端口1}，{NE1-λ1～NE6-端口2～3～NE2-端口1}，则网络管理设备在生成NE1-λ1的路由网络拓扑时，可搜索出其经过的路由NE1-端口1～NE3-端口1～NE3-端口2～NE6-端口1～NE6-端口2～NE2-端口1。其中，NE1发送的跨段计数为0，可以认为NE1为初始网元，因此NE1不需要向网络管理设备发送接收端口，这是由于波长信息对应的波长是由NE1生成的，因此NE1不需要向网络管理设备发送接收端口。
这样一来，对于每个波长信息，当第一网元确定该波长信息对应的波长经过第一网元时，第一网元更新该波长的跨段计数和发送端口并将更新后的该波长信息向未接收到该波长信息的端口对应的下一网元发送，相比现有技术，网元向连接的任一网元发送洪泛信息，本申请实施例不需要发送洪泛信息，能够解决洪泛信息对网络组网规模有约束的问题。并且，第 一网元可以将更新后的跨段计数、第二网元的发送端口、所述第一网元接收到该波长的接收端口以及所述波长的标识保存在本网元，当网络管理设备需要生成波长的路由网络拓扑时，各网元可以向网络管理设备发送跨段计数、发送端口、接收端口以及波长的标识以便于网络管理设备生成波长的路由网络拓扑，相比现有技术根据逻辑配置生成的网络拓扑导致物理波长拓扑与生成的网络拓扑存在差异，本申请实施例是网络管理设备根据各网元中相同波长的跨段计数、发送端口、接收端口以及波长的标识生成路由网络拓扑，而不是根据逻辑配置生成的网络拓扑，能够解决物理波长拓扑与根据逻辑配置生成的网络拓扑存在差异的问题。
