摘要
1 引言基于传统互联网的应用往往是建立在两个用户(两台主机)之间的,随着先进网络体系结构的不断发展和普及,一种新的技术,IP组播(IP multicast),使得大规模多用户间的交互成为可能.
In this paper, we describe our design and implementation of a reliable multicast based shared whiteboard system. The application uses the Scalable and Reliable Multicast protocol (SRM2. 0) to transmit data over the network. Our whiteboard uses a separate SRM framework library and customizes it to achieve the application level semantics. It also uses SNAP to realize the new naming scheme that exposes the structure of application data to the transport layer, thereby enhancing the expression of application's reliability and ordering semantics. We improve its usability and provide increased awareness of remote participants. The application is also extremely flexible.
