HTTP业务是构成3G数据业务的重要部分，因此有必要研究3G网络承载HTTP业务时的性能。介绍了HTTP业务

的基本概念后，提出一种基于网页对象的建模方法，并在OPNET平台上得到实现。最后，根据仿真得到的流量数据，用方差一

时间曲线图和R／S图法分析了模型的自相似特性，验证了模型的正确性。-HTTP operations constitute an important part of 3G data services, 3G networks it is necessary to study the performance of load HTTP business. Introduces the basic concepts of HTTP operations, the proposed object-based modeling website, and realized in OPNET platform. Finally, simulation results of traffic data, a time curve with a variance and R/S Method for the self-similarity of the model to verify the validity of the model.
