Abstract: The basic performance parameters of Local Area Network(LAN) system are summarized as follows: network connectivity, transmission rate, throughout, transmission latency, packet loss rate, link utilization, frame error rate, broadcast frame rate, multicast frame rate and collision rate. The normative test methods are presented for the former parameters. The sampling criteria of links are proposed for acceptance test of LAN systems. Test results validate the applicability and operability of the methods.

Key words: test method, LAN system, performance parameter

摘要： 总结了局域网系统的基本性能指标，包括系统连通性、链路传输速率、吞吐率、传输时延、丢包率、链路利用率、错误率及各类错误、广播率/组播率、冲突(碰撞)率。给出了针对每项性能指标的详细、规范的测试方法，以及待测链路的抽样方法。测试结果说明了各种测试方法的适用性和可操作性。
