Abstract: PURPOSE: An overlay multicast tree construction configuring method and node based on peer to peer available bandwidth is provided to secure a stream service to a user by joining a multicast group. CONSTITUTION: A node requests subscription to a stream supply server or a multicast control server according to the subscription request to a multicast group of a user(S1). The stream supply server or the multicast control server transmits available bandwidth information to the node(S2). The node measures RTT(Round Trip Time) of the nodes in a parent node list. The parent node is transmitted to the stream supply server or the multicast control server(S3). The node is transmitted to the stream supply server or the multicast control server(S4).

Abstract translation: 目的：提供基于对等可用带宽的覆盖组播树构造配置方法和节点，通过加入组播组来保护流服务。 构成：节点根据对用户的组播组的订阅请求，请求订阅流供应服务器或组播控制服务器（S1）。 流供应服务器或组播控制服务器向节点发送可用带宽信息（S2）。 节点测量父节点列表中节点的RTT（往返时间）。 父节点被发送到流提供服务器或多播控制服务器（S3）。 节点被发送到流提供服务器或多播控制服务器（S4）。
