摘要
电信网络正在逐渐过渡到基于IP的下一代网络,作为下一代网络中的核心技术-软交换,由于其支撑业务的多样性以及开放的网络架构,将会面临更复杂的安全环境。NAT的使用在一定程度上给软交换提供了安全保障,但也带来了穿越等技术问题。本文给出了软交换业务中实现地址转换设备穿越的方案,并对各种常用方法进行了对比和探讨。
The telecom network is coming into the era of NGN based on IP.As the core technique of NGN,Softswitch is open network and supports multi-services,so it will face more complicated security environment.The use of NAT guarantee the security in the softswitch,at the same time it brings how to traversing private network.This paper provides a method to transverse NAT in softswitch environment and discusses the common means.
