目前提出的大多数应用层组播解决方案将组成员组织成应用层网格，在该应用层网格上使用距离向量路由协议或类似算法来构造源根分发树。全局路由协议的使用限制了这些系统的可扩展性。其他提出的可扩展到更大数量的接收器的解决方案通过将多播服务模型限制为单源来实现。在本文中，我们提出了一个应用级组播方案，能够扩展到大组的大小，而不限制服务模型到一个单一的源。我们的计划建立在最近的工作内容可寻址网络（CAN）。扩展CAN框架以支持多播的额外成本微不足道，并且由于CAN拓扑的结构化性质，避免了对多播路由算法的需要。鉴于部署的分布式基础设施，如CAN，我们相信我们基于CAN的组播方案提供了简单性和可扩展性的双重优势。
Most currently proposed solutions to application-level multicast organise the group members into an application-level mesh over which a Distance-Vector routingp rotocol, or a similar algorithm, is used to construct source-rooted distribution trees. The use of a global routing protocol limits the scalability of these systems. Other proposed solutions that scale to larger numbers of receivers do so by restricting the multicast service model to be single-sourced. In this paper, we propose an application-level multicast scheme capable of scaling to large group sizes without restrictingthe service model to a single source. Our scheme builds on recent work on Content-Addressable Networks (CANs). Extendingthe CAN framework to support multicast comes at trivial additional cost and, because of the structured nature of CAN topologies, obviates the need for a multicast routingalg orithm. Given the deployment of a distributed infrastructure such as a CAN, we believe our CAN-based multicast scheme offers the dual advantages of simplicity and scalability.
