摘要： 提出了一个在Pastry 上实现的应用层组播系统。系统可以根据接收者对延时和带宽的不同要求，面向实时应用，提供可定制的组播应用。在同时满足延时限制和带宽约束的条件下，接纳尽可能多的用户。通过限制可能父母节点集合的大小，提高系统扩展性。

Abstract: This paper proposes an application level multicast system ( ALMS ) on top of P2P network, Pastry. ALMS can provide customizable real-time service to receivers according to their different QoS requirements. ALMS tries to accept more nodes balancing between delay and bandwidth constraints and raise scalability through limiting the number of potential parents nodes
