OTN network planning setting method in power communication network

Abstract

The present invention relates to an OTN network planning setting method in a power communication network. The method comprises the steps of (1) updating the state information of a current network and releasing completed connection resource, waiting a new connection request, and going to step (2) if the new connection request arrives, (2) using a shortest path algorithm to find two shortest paths which do not intersect to be the working channel WP and the standby channel PP of the connection request, (3) distributing wavelength resource for the working channel and the standby channel and applying the idea of SBPP to share the standby wavelength resource, (4) if both routing and wavelength assignment are successful, the connection request is connected successfully, otherwise the connection request is declined, and going back to the step (1). According to the method, the OTN network planning setting timeliness and level can be improved, and the standardization and rationalization of OTN network design are realized. The method can be widely applied to the field of power communication network planning.

Description

technical field [0001] The invention relates to a method for planning and setting an electric power communication network, in particular to a method for planning and setting an OTN network in an electric power communication network. Background technique [0002] In order to improve the transmission capacity of the power communication network and fully optimize the network structure, it is necessary to carry out research on the technological evolution and networking mode of the backbone transmission network based on OTN (Optical Transport Network) technology. In the face of a large number of network configuration tasks, it is necessary to conduct in-depth research on OTN network channel calculation methods, transmission performance parameter calculation methods, and equipment configuration methods according to the network structure and capacity requirements of different regions, and then carry out OTN network design on this basis. [0003] In the OTN network planning and sett...

AI Technical Summary

Problems solved by technology

[0003] In the OTN network planning and setting in the conventional power communication network, the original manual design mode is generally followed, resulting in relatively weak information aids

In addition, since the OTN transmission network is still in the initial stage of development in the power backbone communication network and has not been applied on a large scale, the formed design and planning information system is also in the internal application stage of each equipment manufacturer

However, with the development of the OTN transport network, multi-vendor equipment runs on the same network, the scale of the network becomes larger and the structure of the network becomes more and more complex. There is a lot of sex work, and it is impossible to obtain a planned network solution in a reasonable, economical, fast, and accurate manner, so it will increase the investment risk caused by planning and setting, and prolong the cycle of planning and setting
