| 摘 要： | 研究了组播会话对发言权控制和网络通信的要求。提出了一个满足这种要求的可靠组播通信模型HSRM,然后结合所研制的基于IP组播的协同学习环境WebLearning+的应用背景给出了基于HSRM的发言权控制模型。该模型协议一致,可以方便地扩展到无主持人和多主持人模式,失效恢复简单,加入和退出灵活,有很好的可扩展性和鲁棒性。

| Abstract: | After studying the requirements for floor control and network communication in multicast sessions,this paper presents a dynamic hierarchical scalable reliable multicast model named as HSRM,and then provides a HSRM-based distributed floor control model to accommodate the application background of WebLearning ,an IP-multicast based col-laborative learning system.This model is based on consistent multicast protocols,and can be easily progressed to non-or multi-master mode,if necessary.Other strengths of the floor control model described in this paper are about easily recovering from failures,joining and leaving freely,good scalability and robusticity. |
