The Impact of Traffic Flow on Network Quality of Service in Complex Networks

Abstract

There are hundreds of millions of communication services in the network. We need to provide basic infrastructure for each service to meet its transmission needs. In this paper, the impact and relevance of traffic on service quality in complex networks are modeled and analyzed, and the relationship between service quality and micro-coupling mechanism and macro-correlation is studied. On the one hand, an elastic physical model of traffic flow in complex networks is established, and the elastic coupling mechanism between quality of service is described from a physical point of view. Specifically, based on the knowledge of elasticity, the relationship between service quality of business flow is analogized to the interaction between elastomers, and a physical model of business flow elasticity is established. This model is used to analyze the intrinsic causes of the coupling relationship between service quality and traffic flow, and a new index to measure the network performance is proposed. On the other hand, based on the micro-coupling mechanism of traffic flow in complex networks, a large-scale network coupled association network is constructed, and then the characteristics of distributed aggregation and coupling Association of large-scale traffic flow in communication networks are studied.
