摘要
随着Internet技术的发展,社交网络(social network)以其独特的魅力,得到了迅速的发展。于此同时,基于P2P(peer to peer)网络环境的社交网络的安全问题、大量网络节点连入网络所带来的IP地址消耗等问题也逐渐被人们所重视。针对这些问题,我们结合VPN(virtual private network)技术的优势,提出了一种针对社交网络特点的SVPN虚拟网络模型。该模型有效地解决了网络节点之间建立安全网络连接的问题,并且通过动态IP地址分配技术明显缓解了大量节点的接入,对IP地址的消耗问题。原型系统的仿真结果表明,SVPN模型虽然在P2P网络环境中引入了一系列安全处理过程,但对节点连接时间和网络整体带宽消耗都控制在可接受的范围之内。
With the developing of the internet, the social network obtained the rapid development by its unique charm. At the same time, the security problem on p2p network and the problem of exhausted IP address attracted more and more attention. To address this issue, a model called SVPN virtual network is proposed, which integrate the advantage of the VPN technology. The model is not only to achieve the secure connection between the peers, but also the IP exhausted problem by dynamic IP allocation technology. This simulation results from the prototype show the although the model introduces a series of security processing procedure, the con nection time and the bandwidth overhead cost is acceptable.
