| 摘 要： | 目前广泛使用的NAT穿越方案STUN方法无法穿越对称型NAT,设计改进STUN方案以克服STUN无法穿越对称型NAT的缺陷,从而实现穿越双对称型NAT的目标.新方案保持STUN方式无须改动现有的NAT设备、协议简单等优点,并尽量避免目前TURN、ICE穿越对称型NAT方案延迟和丢包的问题,满足了越来越多的企业为提高信息安全性需要使用对称型NAT的要求.

| Abstract: | The STUM method of Nat scheme cannot traversing symmetric NAT which widely used presently,improving STUN schyeme design to overcome the STUN cannot traversing symmetric NAT defects,so the target been achieved to traversing the double symmetry NAT.New scheme of STUN requires no modification to existing NAT equipment,protocol is simple,and to avoid the current TURN,ICE traversing symmetric NAT scheme delay and packet loss problem,meet more and more enterprises’ requires that using the symmetry NAT to improving information security. |
