一种生成波长路由网络拓扑方法和装置制造方法及图纸

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，涉及通信领域，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。其方法为：第一网元接收第二网元发送的波长信息的集合；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，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。本申请实施例应用于光网络中生成光波长路由网络拓扑的场景。

Method and device for generating wavelength routing network topology

The embodiment of the present application provides a method and apparatus for generating wavelength routing network topology, which relates to the field of communication, and can solve the problems of the difference between physical wavelength topology and network topology generated according to logical configuration, and the constraint of network size on sending flooding information. The method is as follows: the first network element receives a set of wavelength information transmitted by the second network element; for each wavelength information, if it is determined that the wavelength corresponding to the wavelength information passes through the first network element, the first network element updates the cross-section count of the wavelength; and the first network element sends updates to the next network element corresponding to the port not receiving the wavelength information. The updated cross-section count, the transmission port of the second network element, the reception port of the first network element receiving the wavelength and the identification of the wavelength are transmitted to the network management device. The application example is applied to the scene of optical wavelength routing network topology generated in optical network.
