Traffic route selection method based on optimal-cost intelligent optical network system

Abstract

The invention discloses a traffic route selection method based on an optimal-cost intelligent optical network system, and the method comprises selection of the traffic loading route. The method disclosed by the invention is characterized by comprising the following steps: finding out all traffic routes which satisfy the traffic bandwidth requirement from a start node to source and destination nodes; and selecting the traffic route with the minimal comprehensive cost as the traffic loading route, wherein L is the total link length of all traffic routes, a is the unit price of the link, m is the number of nodes which are passed by all the traffic routes (containing the source and destination nodes of the traffic), b is the unit price of the node equipment, and mu i is the equipment capacity factor of the nodes passed by the traffic routes (containing the source and destination nodes of the traffic). The traffic route selection method provided by the invention can be used for selecting the traffic route with the optimal cost, thereby overcoming the defects of single considered factor, limited applicable network types, incapability of ensuring low cost for the traffic, and the like in the prior art.

Description

technical field [0001] The invention relates to an intelligent optical network, in particular to a service routing selection method based on an optimal cost intelligent optical network system. Background technique [0002] With the rapid development of the Internet and the intensification of market competition, operators need fast and low-cost service provision capabilities. The explosive growth of global data services and its characteristics of suddenness, uncertainty, and unpredictability require optical transport networks to provide more flexible network assignments and efficient and fast network protection and recovery capabilities. ASON technology is used under this demand It was born to promote the transformation of the transport network from the traditional "bandwidth-driven" to "user-aware". [0003] Intelligent Optical Network (ASON) is a new-generation optical network that completes automatic switching functions under routing and signaling control, and can reduce ...
