Realization method of inter-domain traffic engineering with double optimization of operation cost and transmission performance

Abstract

An implementation method of inter-domain traffic engineering that takes into account the dual-objective optimization of operating cost and transmission performance, supports inter-domain collaboration to achieve performance optimization, and formulates a reasonable traffic control strategy taking into account the dual objectives of the lowest operating cost and the best performance; its decision-making principle is Multi-criteria modeling fully considers actual network requirements, handles multiple stream requests at the same time, regulates network traffic in real time, divides and conquers problems, and avoids or reduces leakage of sensitive information; adopts game thinking to take into account both cooperation and competition of participants. The specific steps are: establish the optimization goals from the perspective of performance and operating cost, use the law of flow conservation to express the constraints that meet the dual optimization goals of performance and operating cost, and perform Lagrangian decomposition. The present invention can process large-scale cross-domain traffic transmission requests in real time, and solves the problem of waste of resources in which existing operators only adjust cross-domain traffic according to limited autonomous domain information and their own interests, regardless of the overall interests, or do not consider the processing method of operating costs .

Description

technical field [0001] The present invention relates to a method for implementing inter-domain traffic engineering with dual-objective optimization, to be precise, to a method for realizing inter-domain traffic engineering with dual-objective optimization of operating cost and transmission performance, belonging to inter-domain traffic engineering or network construction The technical field of model and its performance optimization.

[0025] In view of this, the purpose of the present invention is to provide an implementation method of inter-domain traffic engineering that fully considers the actual needs of the network, takes into account the dual-objective optimization of operating costs and transmission performance, and handles large-scale cross-domain traffic transmission requests in real time. Some operators ignore the overall interests and only adjust traffic based on limited autonomous domain information and their own interests, which leads to the waste of network resources, and only focuses on performance optimization without considering operating costs.
