本文内容分两部分,主要是讨论在分组交换网开发完成后,如何进行一致性测试和网络流量测试。前半部分以美国国家标准局NBS的X.25一致性测试标准为基础,介绍了如何进行X.25链路层、分组层的一致性测试,以及作者在测试自行开发的X.25通信控制器时遇到的一些问题;后半部分介绍了在该通信控制器上开发的分组交换同流量发生器软件、产生流量的各种参数指标及相应的问题。此外,作者还介绍了对分组交换同进行测试的一些看法. This article is divided into two parts, mainly to discuss how to conduct conformance testing and network traffic testing after the development of packet switching network is completed. The first half is based on the NBS X.25 conformance test standard of the National Bureau of Standards of the United States, and describes how to conduct conformance testing of the X.25 link layer and packet layer, as well as the author’s test of the self-developed X.25 communications controller Some problems encountered in the latter part of the communication controller developed on the packet switching traffic generator software to generate traffic parameters of the various indicators and the corresponding problems. In addition, the author also introduced some of the views on packet switching with the test.
