网络层组播在大规模流媒体直播系统中的研究与实现

Design and implementation of network multicast in streaming media direct broadcast system

组播可以有效实现多点之间通信,如何利用网络层组播技术实现流媒体直播系统,是当前的研究热点之一。基于MixCast模型,提出并实现了一种新的基于网络层的安全组播模型。针对当前组管理协议IGMP不提供接入控制,任何端点用户可自由地加入组播组,缺乏安全控制问题提出了依靠应用层单播对接收者认证,提出一种解决网络层组播的安全性问题和可控性问题的方法。实验结果表明,本系统具有良好的安全通信效率和可控性。

Network layer multicast can effectively implement the one-to-many communication,and how to use network layer multicast technology to carry out the stream media living broadcast system is one of the currently hotspots.The paper advanced and had achieved a new inter-domain secure multicast model,and aiming at the problem of lacking of secure control that IGMP didn t provide access control so that any end user could freely join the multicast group,advanced one of the resolutions of security and controllability...
