A method and system for testing the effectiveness of network traffic scheduling simulation

Abstract

The invention discloses a method for testing the effectiveness of network traffic scheduling simulation, which includes sending constructed network traffic to the network source node side; responding to network traffic transmission in the network, simulating the network, simulating network intermediate node failures, and obtaining network The optimal scheduling path of traffic and the receiving statistics of the network sink node side; the scheduling path of network traffic after the actual failure of the network intermediate node is obtained; the scheduling path after responding to the actual failure is consistent with the optimal scheduling path after the simulated failure, and the simulated failure If the final receiving statistics are consistent with the expected results, the traffic scheduling simulation function is correct and effective. At the same time, the corresponding system is disclosed. The invention compares the optimal scheduling path obtained by simulation with the actual obtained path, compares the reception statistics obtained by simulation with the expected result, and judges the effectiveness of flow scheduling simulation through the comparison result.

Description

technical field [0001] The invention relates to a method and system for testing the effectiveness of network flow scheduling simulation, belonging to the field of testing SDN networks. Background technique [0002] With the rapid development of computer technology and network communication technology, the speed of network construction is accelerating, the scale of the network is getting larger and more complex, and the impact on the business when the network fails is also increasing. Occurrence is inevitable, so redundant nodes, backup paths, etc. will be considered in network design and service design. For a relatively complex network, unless a particularly important time-related data service, a static and fixed backup path may be designed. Other services generally use dynamic routing calculations, which are calculated in real time according to the specific conditions of the network structure, so when a fault occurs, it affects service recovery. There are many factors, suc...

Problems solved by technology

The algorithm design and implementation of the simulation function affect the correctness and effectiveness of the simulation results. Given that there is no unified standard for the simulation function of network traffic scheduling at present, the quality of the simulation functions provided by various manufacturers varies. Whether the simulation results are consistent with the actual results and whether the simulation results are valid Wait, there is no criterion for judging
