本文提出了一种支持新型网络用户自定义报文性能测试的方法。在充分利用现有测试设备和测试环境的情况下，为新型协议的用户自定义格式报文提供了一个通用灵活的接口，将用户定义的报文格式转换成通用协议报文格式进行测试。用户不用关心测试设备底层数据报文的构造过程，只需在自定义协议上进行数据的定义、转发、测试等，中间的转换过程对用户是透明的。实验表明，系统可测试非IP格式的报文，兼容性好，用户界面友好，灵活性强。

The paper presents a method which supports the test of a new network protocol. We design a normal and agility interface for the testers to define and construct the packets of a new protocol, then transform the packets to a  standard protocol type while the system working under the existing condition. The testers do not concern the switching process, and it is transparent. The testers initialize the structure of the packets,construct packets, set up the interface parameters and run the testing process to get the results. Experimentations indicate that the system is more compatibile, flexible and friendly.
