| 摘 要： | 基于UDP打洞的NAT穿越技术一般需要架设专用中央服务器Ⅲ,该方法在扩展性、可靠性、灵活性和性能上都存在局限性.通过对天网Maze2]P2P节点的网络属性分析,动态选举合适节点替代专用服务器来完成节点在不同内网之间的穿透,形成一种可扩展网络3].从而提出了在纯P2P模式解决NAT穿越的构架,增强了系统的健壮性和失效调节能力.

| Abstract: | NAT traverse technology based on the method of UDP punching hole generally relies on central servers to help1].After analysis of P2P peers' network attributes in Maze system 2],dynamically electing appropriate peers to help network traverse for peers in different NATs just as those central servers,that forms a scale-free network3].As a result,the architecture of pure P2P model based NAT traverse is presented,which improved its robustness and fail-over ability. |
