Internet topology simulation generation method and system based on structure model

Abstract

The invention discloses an Internet topology simulation generation method and system based on a structure model, and the method comprises the steps: designing a topology simulation method through taking the topology feature parameters of a network topology as the input, and providing necessary technical support for the network simulation and routing application of an Internet simulation system; simulating and generating a network topology structure by taking the stable and invariant characteristic parameters of the network topology decomposition structure on the real topology historical evolution process as input. Furthermore, compared with other network topology simulation generation technologies, the input real / virtual connection component disclosed by the invention is richer in characteristic parameter characteristic types, so that a more accurate network topology simulation generation result can be obtained. Compared with a traditional simulation tool, the evolution stability characteristic of the local structure of the network topology can be captured more accurately; therefore, a simulation topological structure closer to a real network is generated, and a more realistic simulation topological environment can be provided for research, development and testing of routing protocols, resource positioning and other Internet technologies.

Description

Technical field[0001]The present disclosure relates to the technical fields of network topology and network simulation, and in particular to a method and system for generating Internet topology simulation based on a structural model, which is suitable for accurate and rapid simulation generation of network topology in the past, current and future states.Background technique[0002]The network topology is usually divided into three levels, namely the IP layer, the routing layer and the autonomous system (Autonomous System, AS) layer. Among them, the IP layer uses the computer terminal IP address as the node, the routing layer uses the data communication routing device as the node, and the AS layer uses the autonomous system domain as the node. An AS node corresponds to a set of routing nodes belonging to the same administrative domain, and a routing node consists of a series of IP addresses. Therefore, the AS layer describes the macro characteristics of the (Internet) network topology....
