A new mechanism for constrained-based multicast
Youqing Cheng, Shaohua Yu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2006
As to the traditional unicast and broadcast, multicast is also a kind of data transfer mode of IP network. Because multicast can save bandwidth, reduce network load, multicast is widely used on real time data transfer, video conferencing, distance education and Internet living broadcast. But multicast encounters more security challenges than unicast, such as unauthorized data sources and unauthenticated users. This paper discusses in detail about the multicast source control, multicast routing control and multicast user control. The main contribute of this paper is that a new multicast user control scheme is proposed and fully illustrated. And a whole mechanism to manage constrained-based multicast application is clearly described and implemented in this paper to achieve multicast source control, routing control and user control.
