Multi-session delay damage simulation based on time delay strategy
With the increasing demand for satellite network,vehicle-connected network,industrial network and other service simulation,this paper proposes a multi-session delay damage simulation method based on delay range strategy to build flexible software network damage simulation,aiming at the problems of small number of analog links,low flexibility and high resource occupation of traditional dedicated channel damage instruments. In this method,the delay damage of each session flow is identified and controlled independently,and the multi-queue merging architecture based on time delay strategy is adopted to reduce the resource consumption. The experimental results show that compared with the traditional dedicated device and simulation software NetEm,the proposed method supports the independent delay configuration of million-level links,increases the number of session streams from ten to one million,and reduces the memory consumption by at least 85％ under each bandwidth,which meets the requirements of large scale and accuracy,and greatly reduces the system cost.
