| 摘 要： | With the boom of the network technology, all kinds of services based on the Internet come into being. A-mong them, the most promising one is the video service. All of this kind of service has been paid much attention,such as videoconference and video-on-demand. Because of the instability of the Internet environment, the traditional Client/Server mode in the LAN, which is used to support the data transmission, is not suitable any longer. And the newly designed Server/Proxy/Client one is more effective. This paper describes this architecture and its service pat-tern, does some deep research on the key issues of the design of the proxy cache server, such as the caching and re-olacernent nlr the viden data, the management and coordination of multi-proxy-servers.

| Abstract: | With the boom of the network technology, all kinds of services based on the Internet come into being. Among
them, the most promising one is the video service. All of this kind of service has been paid much attention, such as videoconference and video-on-demand. Because of the instability of the Internet environment, the traditional Client/Server mode in the LAN. which is used to support the data transmission, is not suitable any longer. And the newly designed Server/Proxy/Client one is more effective. This paper describes this architecture and its service pattern, does some deep research on the key issues of the design of the proxy cache server, such as the caching and replacement of the video data, the management and coordination of multi-proxy-servers. |
