点对点（P2P）系统现在越来越流行，并广泛应用于各种类型的应用程序中。在本文中，我们提出了一个基于超级对等的双层P2P覆盖网络，该网络采用基于电荷的泛洪（CBF）算法，这是一种分布式多媒体对象查找协议。普通对等体层和超级对等体层分别由一组普通对等体和一组超级对等体组成。多个具有共同属性的普通对等体（如文件）与超级对等体相互连接。超级对等体和普通对等体的集合称为集群。在集群中，普通对等体试图在没有超级对等体帮助的情况下找到目标对等体。如果目标文件不在集群中，则普通对等体请求超级对等体代表普通对等体查找目标文件。然后，超级对等体通过在超级对等体层使用CBF算法将请求转发给其他超级对等体
Peer-to-peer (P2P) systems are now getting popular and are widely used in various types of applications. In this paper, we newly propose a superpeer-based two-layer P2P overlay network with the charge-based flooding (CBF) algorithm, a look-up protocol for distributed multimedia objects. The layers of normal peer and superpeer are composed of a set of normal peers and a set of superpeers, respectively. Multiple normal peers with some common properties, e.g. files, are interconnected with a superpeer. A collection of a superpeer and normal peers is referred to as a cluster. In a cluster, a normal peer tries to find a target peer without being helped by a superpeer. If the target file is not detected in the cluster, the normal peer asks the superpeer to find the target file on behalf of the normal peer. Then, the superpeer forwards the request to other superpeers by using the CBF algorithm at the superpeer layer
