IPv6/IPv4隧道代理的实现

IPv6/IPv4 Tunnel Broker Implementation

隧道（ｔｕｎｎｅｌ）技术是互连网从ＩＰｖ４向ＩＰｖ６过渡时期的重要技术，手工配置隧遁的效率不能适应ＩＰｖ６网络快速发展的需要，隧道代理 （Ｔｕｎｎｅ Ｂｒｏｋｅｒ）是实现隧道自动配置和管理的一种方法。隧道代理模型具有通用性和可控制性强的特点。本文讨论改进并简化的隧道代理模型及其在ＣＥＲＮＥＴ ＩＰｖ６试验床上的实现细节。

Tunneling is an important approach during the transition period from IPv4 to IPv6. Currently most of the tunnels are configured manually, but it could not meet the requirement of deploying IPv6 rapidly. Using tunnel broker is an approach for automating the tunnel configuration and management. The tunnel broker model is characterized with its controllability, and it fits a variety of virtual networking. This paper discusses the tunnel broker model improved and simplified in the CERNET IPv6 testbed, and t...
