Building and simulation method of large-scale communication network simulation model

Abstract

The invention provides a building and simulation method of a large-scale communication network simulation model, belonging to the communication technology field and relating to the communication network technology. An actual network is divided into multiple relatively independent areas and subareas according to geographical position, connecting relation and business size of all network units (routers) in the actual network; one server is adopted as an analog front end to simulate the working process of one subarea; one server is adopted as a sub-dispatching unit to coordinate and dispatch allanalog front ends in one area; one server is adopted as a general dispatching unit to coordinate and dispatch each sub-dispatching unit. In the invention, the simulation model which is basically consistent to the actual network is adopted, the working process of the whole network is distributed to the different servers, so as to speed up the simulation velocity; and the simulation result is direct and accurate and is in accordance to practical condition. The method is suitable for large-scale and superlarge scale network simulation.

Description

technical field [0001] The invention belongs to the technical field of communication, relates to communication network technology, and in particular relates to a structure and a simulation method of a simulation model of a large-scale communication network. Background technique [0002] With the rapid increase of communication network traffic and the continuous expansion of network scale, a large number of new devices with stronger functions and higher complexity have become the main components of the current communication network, making the complexity and scale of the current network larger than the previous network. There is a substantial increase. In order to save costs and plan the network reasonably, people often use the method of network simulation to establish a network simulation model with a computer, and use the model to predict and study important functional parameters and operating mechanisms of the communication network. On the one hand, this provides a conven...

Problems solved by technology

However, this structure also has some disadvantages: First, the computing distribution and scheduling tasks of the entire network are completed by a single server, which can basically meet the scheduling requirements of small-scale networks. For large-scale and ultra-large-scale networks, a single scheduling server may become bottleneck; secondly, the simulation model is not established according to the actual structure of the network, which may generate a large amount of coordination and control information for the simulation model itself, thereby increasing the business load of the simulation model and prolonging the simulation time
