Network topology optimization design method considering business process characteristics

Abstract

The invention relates to a network topology optimal design method in consideration of business process features. The method comprises the following steps: step one, determining network information according to an engineering application demand, wherein the network information comprises network node amount, network business information, and other information required by the engineering application;step two, establishing a network topology optimal design model in consideration of the business; regarding the network topology design problem in consideration of the business as a target function optimization problem with a constraint condition, wherein the constraint condition is determined according to engineering actual condition, an optimal target is the loaded network performance index of the specific business, and the solution is the optimal network topology structure; and step three: solving the optimum network topology based on the genetic algorithm. The method disclosed by the invention has the advantages: (1) the business process features can be considered while supporting the network topology design, and the network topology with the optimum performance can be obtained; and (2) the acquired network topology in consideration of the business process features can improve the business reliability in the network operation, and has important engineering significance.

Description

technical field

[0001] The invention belongs to the technical field of reliability and safety (safety system engineering), and in particular relates to a network topology optimization design method considering the characteristics of business processes. Background technique

[0002] The purpose of communication network design is to meet users' needs for different network services. However, with the development of network technology and network services, users' demand for resources continues to grow and change, resulting in numerous and intertwined network service traffic, and the network scale is getting larger and larger. . At this time, traditional network design methods, such as methods based on experience, experimentation or estimation, have certain limitations for the design of some large and complex networks. As the basic link of network design, network topology design plays a vital role. A reasonable network topology design can not only obtain high network reliabilit...
