Abstract

The present invention discloses a large-scale routing simulation method based on the hardware, and provides a large-scale routing simulation technique which is realized with a high-performance special network processing specialized platform. The initialization process of simulation is generated sequentially by three steps of: simulation of the network performance, loading of the corresponding QoS algorithm code and the virtual routing table. The simulation process comprises the following steps: firstly, receiving the real network data packages; then, converting the real network data packages to the virtual packages used for simulation; transmitting the virtual data packages between the virtual network devices; and converting the data packages to real data packages for entering the real network. The large-scale network routing simulation method based on hardware according to the invention has the advantages of high processing performance, providing of reliable virtual-real converting interface, strong extendibility, reduced cost, reinforced convenience and reinforced operability.

Problems solved by technology

But doing so also brings the problem of parallel processing synergy and the problem of the effectiveness of simulation data control

In addition to the problem of performance bottlenecks, the existing technology only focuses on the forwarding of IP packets in the simulated network, but lacks the consideration of routing packets, and rarely involves the interactive characteristics of routing protocols

In addition, the existing network simulation software is almost all built on the general computer platform

Ordinary CPUs and operating systems are relatively inefficient in processing network data streams, so the functions of these network simulation software are limited by the performance of the hardware platform

Moreover, the research on network data transmission and routing selection needs to build an experimental environment close to the real network, using real routing equipment costs a lot of money, and the configuration is complicated and cumbersome
