Research and application of Web caching workload characteristics model
Web缓存流量特征模型研究和应用

A synthetic Web workload generator (WebSimGen) was designed and implemented based on the mathematic model established by Web characteristics. The simulated experiments made use of two-level proxy caching and ADF (Aggregation, Disaggregation and Filtering) model to evaluate the reference characteristics and performance of synthetic Web workload, which showed that the synthetic workload had the similar performance characteristics with the real traces. The generator has the advantage of flexibility and can overcome some disadvantages of the real traces, so it can provide an important basis for further improving Web caching performance and prefetching technology.
