目前基于流言的协议遵循一个纯随机选择过程，容易导致收敛时间长和大量的非互联网服务提供商（ISP）友好的流量。提出了一种社区感知的流言协议。通过将对等点聚类到社区中，对等点可以根据社区的邻近程度来知道他们在网络中的位置。该方案可以提高邻居选择的效率，减少跨ISP的非ISP友好流量。分析和仿真结果表明，提出的Gossip协议能够提高物理网络的利用率，提高整体性能，吸引更多的P2P用户参与。
The current gossip-based protocols follow a pure random selection process,easily resulting in long convergence time and large volume of non-Internet service provider ( ISP) -friendly traffic. A community-aware gossip protocol is proposed. By clustering peers into communities,peers can know their positions in the network in terms of vicinities to the communities. The presented scheme can increase the efficiency in neighbor selection and reduce the non-ISP-friendly traffic across ISPs. Analysis and simulation show that the proposed gossip protocol can improve the utility of physical network usage,and stimulate the overall performance as well as appeal to more participating peer-to-peer ( P2P) users.
