Implementation method of inter-domain flow engineering achieving double optimization of operating cost and transmission performance

Abstract

Disclosed is an implementation method of inter-domain flow engineering achieving double optimization of operating cost and transmission performance. Performance optimization is achieved through supporting inter-domain cooperation and reasonable flow control strategy is formulated through achieving two objects of the lowest operating cost and the best performance. Decision-making principles of the method are that modeling is achieved in multiple criteria, actual network need is considered comprehensively, a plurality of stream requests are processed simultaneously, a network flow is adjusted and control in real time, problems are divided to be solved and sensitive information leakage is avoided or reduced. A game thought is adopted and cooperation and competition of participants are considered. The method comprises the following specific steps: optimization objects are respectively determined from the angles of the performance and the operating cost, constraint conditions satisfying the two optimization objects of the performance and the operating cost can be expressed through a flow conservation law and Lagrange decomposition is performed. The implementation method can process large-scale cross-domain flow transmission requests in real time and solves the problem that resources are wasted due to the fact that a prior operator adjusts cross-domain flow according to limited autonomous domain information and self-interest without consideration of interests of the whole situation or the processing method without consideration of operating costs can be corrected.

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. Background technique [0002] The rapid self-growth and expanding scale of the Internet pose a huge challenge to the effective management of the network and the technological development of the Internet. With the emergence of a large number of new network applications and the networking of social behaviors, the demand for security and controllability of behaviors between network domains is increasing. The Internet Engineering Task Force (IETF) proposed the concept of Traffic Engineering TE (Traffic Engineering) in response to the situation, and ...

[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.
