| Abstract: | MCU(Multi_point Control Unit) is the key equipment of multi_point video conference. Multi layer network connected with multi MCUs can implement large_scale video conference.Because of their characteristic of unbounded geographical zone, multi MCUs are set on each floor in a building or at another office building, or different zones.It brings about the problem how to manage and control dispersing MCUs. Creating system of controlling MCUs in long_distance is the optimal scheme to solve this problem. This paper analyzes not only the characteristic of multi_layer distributed system structure provided by the system of controlling MCUs in long_distance, but also the special requests in application of the Internet.The methods to select thread type of component,design interface,arrange component physical location and test component in idiographic application condition are introduced.And how to unite COM and ASP to create COM components in ASP applications is discusseed in detail.Using the technology in the paper, programmer can set up greater Internet applications.They have good performance and multi_user.At last,how to select COM's security and its lifecycle in COM's design and realization is discussed. |
