一种面向负载均衡的电力OTN路由优化算法
A Load balance Oriented Optimization Algorithm for Electric Power OTN Route
摘要
Abstract
Optical transmission network (OTN)business planning focuses on the shortest path while doesn't consider global load balance,which may cause high partial pressure and increase operational risk of the network. Therefore,this paper ana-lyzes common objectives and constraints of current business route optimization algorithms,by combining with peculiar fea-tures of optical signal noise ratio (OSNR)of OTN network,it presents a kind of optimization algorithm for business route with the purpose of load balance that comprehensively considering traditional constraints of electric power OTN network such as optical transmission constraint and hops. This algorithm firstly comprehensively considers link load,OSNR and route hops,and builds the optimization model for business route optimization aiming at network load balance and regarding OS-NR,optical power and hop as constraints. Secondly,the algorithm analyzes characteristic of the optimization model and chooses the ant colony algorithm for route optimization. Finally,according to current network data of one southwest provin-cial electric power company,it verifies compared with other traditional route optimization algorithms,this mechanism can keep network load balance at the same time of ensuring OSNR and business hops.关键词
