LISP与非LISP站点间交互机制研究

Research on the Interworking Mechanism between LISP and Non-LISP Sites

当前互联网存在着路由可扩展性、多宿主、流量工程及对移动性和安全性支持不足等问题。LISP协议作为一种基于身份与位置分离的解决方案,可在现有网络设施的基础上增量式部署,而增量式部署必须实现LISP站点与传统的非LISP站点间的交互。对Proxy-ITR和Proxy-ETR这两种交互机制进行分析与研究,并实验模拟Proxy-ITR和ProxyETR在交互中的作用。结果表明通过设置Proxy-ITR和Proxy-ETR可以很好地解决LISP站点与非LISP站点间正常通信的问题。

The current Internet has been faced with many problems such as routing scalability, multi-homing traffic engineering and lack of support for mobility and security. As a solution based on the identity and location separation, the Location/ID Separation Protocol （LISP） can be incrementally deployed on the basis of the existing network infrastructure, while the interworking between LISP and non-LISP sites must be solved. Investigates the mechanisms on the Proxy Ingress Tunnel Router and the Proxy Egress Tunnel Router, simulates the function of the Proxy-ITR and Proxy-ETR. The results reveal that the Proxy-ITR and Proxy-ETR can solve the normal communication problem be- tween LISP and non-LISP sites well.
