Switching unit simulation system and method based on discrete event

Abstract

The invention discloses a switching unit simulation system and method based on a discrete event, mainly aiming at solving the problem of high simulation complexity and long implementation cycle in the prior art. The implementation scheme comprises the following steps: firstly, designing a two-dimensional event linked list and an event scheduler according to a discrete event simulation mechanism to drive system simulation; then designing a general composition module of a switching unit; designing a specific event flow according to functional logic behaviors of the module; and then implementing various events and event relations by using software languages according to the event flow; and finally, calling an event scheduler module for simulation, and calling a performance statistics module to calculate various performance parameters. According to the switching unit simulation system and method disclosed by the invention, the software simulation time of the switching unit can be shortened, the simulation complexity can be reduced, and a reliable basis can be provided for the scheme design of the switching unit.

Description

technical field [0001] The invention belongs to the field of simulation technology, in particular to a simulation technology for switching units, which can be used in network equipment. Background technique [0002] The rapid development of information technology has put forward stricter requirements and more demands on equipment in the network such as routers and switches. The switching unit has always been a crucial node in the network equipment, which plays a key role in connecting links and transmitting data. With the continuous increase of data traffic and the variety of services in the network, the structure of the switching unit becomes more and more complex. This also brings higher requirements to the design and implementation of the switching unit. Therefore, how to simulate and verify the design scheme before the switching unit is implemented is particularly important. [0003] The steps of researching a switching unit mainly consist of analysis requirements, de...

Problems solved by technology

[0006] The Opnet and NS2 simulation platforms are mainly used for the simulation of network protocols. The data flow process inside the switching unit is quite different from the network protocol. Moreover, the simulation complexity of these two simulation platforms is high and the implementation period is long, resulting in the lack of solutions for the switching unit. Timely verification, which increases the development cost of the switching unit
