Scheme And Implementation For Measuring The Capacity Of MCU In IP Video Conference System

Multimedia Control Unit(MCU) is an important control component in Ip video conference. Its performance directly influences the quality of the video conference. Capacity is a key parameter used to measure how good the MCU is. But there is no formula that can deduce the capacity of MCU because its capacity is influenced by many factors. Neither is there an open and simple method to test the capacity of MCU in this field. To solve this problem, a new scheme to test the capacity of MCU is put forward in this paper.In this paper the process how MCU achieves its capacity is presented in detail,as well as a few factors influencing the capacity of MCU. And after the difficulty of finding the capacity by formula and by testing is discussed, a new scheme designed to test the capacity of MCU is put forward.The emphasis is put on the design and implementation of a test device used to test the capacity of MCU and on the detailed steps performed in the scheme.The scheme discussed in this paper solves this problem. It is a new method to test the capacity of MCU, which breaks the conventional one. This scheme is not only simple and feasible, but consumes less money and fewer resources, which reduce the difficulty of testing to the least. So this scheme has high practicability. The test device designed in this scheme to test the capacity of MCU has passed the test in experimental environment. Practice has proved the correctness and feasibility of the scheme principle for the capacity test of MCU designed in this paper. So far, in this field, no device or method analogous to the ones introduced in this paper have been found.
