【摘要】 基于交互式连通建立草案协议,综合运用网络地址转换(NAT)会话穿越工具和中继穿越工具,设计一个媒体流穿越NAT的算法实例。使用请求/应答交互方式,探索通信双方NAT拓扑部署,通过排序算法找到并选择一条最优的传输路径。在Linux下进行编程测试,能使媒体流较好地穿越不同拓扑部署的NAT。更多还原

【Abstract】 An algorithm instance is designed about traversing Network Address Translator(NAT) for media streams,in which Session Traversal Utilities for NAT(STUN) and Traversal Using Relays around NAT(TURN) based on the Interactive Connectivity Establishment(ICE) are used synthetically.The algorithm explores the NAT topology for peer by the request/response interaction and finds the best path.The program test on Linux proves that media streams are able to pass through various topologies of NAT deployment.更多还原
