Abstract: The replay of the application’s behavior is essential to the protocol design, network troubleshooting, performance evaluation and network management. It is important to develop a simple and powerful method to implement the replay of the application’s behavior which is complicated along with the appearance of new applications. Based on the detailed analysis of the most of all the typical replay-methods and frameworks related to the application’s behavior, it gives a new replay-method based on template which is rely on the systemic classification of all the application’s behaviors. As the presentation of the experimental results, using the method, it reduces the complexity of building a repay-system of application behavior, especially when adding new applications into the replay-system.

Key words: 5-tuple flow, replay method, application’s behavior, template

摘要： 应用层业务行为回放在协议设计、故障诊断、网络监测管理和性能评估等领域有着重要应用。该文分析了具有业务回放功能的网络监控系统所采用的方法和框架，指出了在面对新协议/应用层业务增加时，回放功能等方面的不足，分类总结了应用层业务行为，提出并实现一种基于模板 的应用层业务行为回放方法。试验表明，该方法适合于存在动态业务添加，尤其是对新业务的添加情况下的应用层业务行为回放，具有较好的灵活性和可扩展性。
