摘要： 介绍了一种基于网络动态自适应的集群式监控系统的体系结构模型与实现的关键技术。系统建立在Client/Server模式基础上,采用H.263视频编码技术,利用实时传输协议RTP,实现了系统对多种网络状况的动态自适应和拥塞控制,保证了系统客户端的QoS。同时,服务端采用集群式的拓扑结构,客户端登录时采用严格的安全认证和透明接入,使得系统具有较好的安全性和可扩展性。

Abstract: This paper introduces the framework of the network aware clustered monitor system and the key techniques to implement theframework. A codec based on H.263 is adopted and RTP is proposed to adapt to the network condition and to control the network congestion, whichprovides a satisfying video QoS. And because of the clustered structure in server system as well as the strict authentication and transparent access,the system is more secure and extensible.
