Anycast通信模型在P2P网络中的设计与实现

Design and Implementation of Anycast Communication Model in P2P Networks

为了解决Anycast通信模型扩展局限性,提出了一种在P2P(Peer-to-Peer)网络中的Anycast通信模型。以Pastry网络为实例,详细论证了利用Pastry网络的区域特性能够实现Anycast通信模型的可行性,并且详细阐述了Anycast通信模型在Pastry网络中的具体实现过程。在仿真环境中,我们实现了此模型,实验数据表明Anycast消息基本可以被路由到与源节点距离最接近的Anycast组成员,实验结果证明了此模型的有效性与高效性。

In order to solve Anycast＇s scalability, an Anycast communication model was proposed in P2P （Peer-to-Peer） networks. A P2P example was adopted, the feasibility of implementing an Anycast communication model was demonstrated by utilizing Pastry＇s locality, and the issue ofhow to design and implement an Anycast communication model in Pastry was expounded in detail. In a simulation environment, the model was implemented and the experimental data show that, with high probability, a message addressed to an Anycast group can be routed to the closest Anycast member in the Anycast group. The experimental result proves the effectivity and efficiency of the model.
