摘　　要：多点控制单元(MCU)是IP视频会议系统中的重要控制部件,其性能好坏直接影响视频会议的质量。容量是衡量MCU性能好坏的一个重要参数,本文简要介绍了影响MCU容量的一些因素,分析了用公式推导MCU的容量和实际测试MCU的容量的难度,在此基础上,重点提出了一种测试MCU的容量的方案,并在详细介绍了此测试方案后对测试结果以及测试参数进行了分析。MCU is an important control component in IP videoconference.Itsconference. Its capability directly influences the quality of the videoconference.Itsconference. Capacity is a key parameter used to measure how good the MCU is. In this paper a few factors influencing the capacity of MCU is briefly presented, and then a new scheme to test the capacity of MCU is put forward after the difficulty of finding the capacity by formula and by testing is discussed. The emphasis is put on the presentation of this scheme and the analysis of the result of the test.
