摘　　要：为了解决IPv4地址匮乏问题,网络中部署了大量的NAT设备,而NAT的部署破坏了Internet端到端的特性,并给不断发展的网络多媒体应用带来了障碍。针对该问题,提出一套系统化的NAT穿透方案,实现了一种具有NAT穿透能力的构件,可平滑地植入现有的流媒体产品中,并降低软件开发的复杂度,从而可很好地解决NAT部署带给流媒体的障碍。In order to solve the problem of the IPv4 address scarcity,network deploy a large number of NAT equipments,while the deployment of NAT destroyed the Internet end to end performance,and has brought obstacles for the the network multimedia application development. Aiming at these problem,a systematic NAT traversal solution was presentd to achieve a member that has a NAT traversal capability,it can stream into the existing media products smoothly. The complexity of software development can be reduced. The obstacles of NAT deployment to the streaming mediaare also well soluted.
