摘要
软交换设备如何在局域网间互通目前还没有应用标准,而现有草案由于其在实现中的复杂性、不易兼容性,也不被开发商所看好。对目前几种解决网络地址转换(NAT)/防火墙穿透的方案进行分析,并针对UDP对NAT的简单穿越(STUN)方案给出了具体实现过程。
At present there is no application standard on Softswitch devices' interworking among LANs. With the complexity and incompatibility current drafts are not promising in the view of carriers. This article analyses several solutions dealing with NAT/Firewall passing-through schemes and presents an implementing procedure about Simple Traversal of UDP through NAT.
