Abstract

The invention discloses an ROADM all-optical network planning method and device based on a WSON function. The method comprises the following steps: collecting data information and service information in an all-optical network, and planning a service working route, a service electric relay node and a service working route channel number in the all-optical network, generating an interruption scene corresponding to each shared risk link group according to the information of each shared risk link group in the all-optical network, collecting all risk services in each interruption scene, and calculating a service recovery optimal source and destination node, a service recovery electric relay node, a service recovery route and a service recovery route channel number of each risk service; and counting the construction scale of the all-optical network according to the information corresponding to the service working route and the service recovery route, and optimizing the initial topological structure of the all-optical network in combination with a preset optimization reference condition. Therefore, by implementing the method, the accuracy of network resource planning can be improved, and the rationality of planning the network topology structure can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a ROADM all-optical network planning method and device based on WSON functions. Background technique [0002] With the development and promotion of network communication technology, all-optical networks are more and more widely used in people's lives, and the data traffic and data carrying capacity in the network continue to increase. At present, 100G technology using coherent reception technology has been commercialized on a large scale in major operators. Mature digital information processing technology has realized compensation for dispersion in the electrical domain, making dispersion no longer the key to restricting long-distance transmission of DWDM systems. factor. At the same time, WSS technology continues to improve and mature in terms of improving reliability, increasing density, and reducing costs, which promotes the development of all-optical networks w...
