Optical path establishment method and system for power distribution communication network

Abstract

The invention relates to an optical path establishing method and system for a power distribution communication network. The optical path establishing method for the power distribution communication network comprises the following steps of: acquiring a plurality of to-be-transmitted power distribution services in the power distribution communication network, detecting a request frequency of each to-be-transmitted power distribution service in a set time period, and according to a sequence of the request frequencies from big to small, carrying out sorting on the to-be-transmitted power distribution services; according to the sorting, sequentially determining each to-be-transmitted power distribution service as a target power distribution service, and identifying a source node and a sink node of the target power distribution service; according to each routing port of the power distribution communication network, establishing a virtual link between the source node and the sink node; and when residual transmission capacity of the virtual link is higher than or equal to service capacity of the target power distribution service, establishing an optical path corresponding to the virtual link in the power distribution communication network. According to the optical path establishing method and system for the power distribution communication network, which are provided by the invention, on the basis of ensuring a transmission effect, energy consumption caused in the process of transmitting the power distribution services is effectively reduced.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for establishing an optical path of a power distribution communication network. Background technique [0002] In recent years, with the rapid growth of distribution network IP services such as power quality detection, power consumption information collection, and power transmission and transformation status detection, the original Multi-Service Transfer Platform (MSTP) of the distribution network is facing challenges. Comply with the IP trend, complex time synchronization, low transmission efficiency and low scalability. The packet transport network (PacketTransport Network, PTN) is designed for the bursty requirements of packet IP service traffic, with packet service as the core and supports multi-service guarantee, using the IP+SDH (Synchronous Digital Hierarchy, synchronous digital system) mode, Compared with MSTP, it has the advantages of low oper...
