一种扁平身份标志位置解析系统

Locator resolving system for flat identity

一体化网络是一种基于身份/位置分离的新型网络架构。为了解决身份/位置分离后为任意的身份标志提供对应的位置标志的问题,提出了一种三层映射信息存储解析系统,将解析系统分为三个不同的等级：活跃本地级、中性缓冲级和惰性全局级。基于每个接入路由器通信对端的局部频度不均性,映射信息被存储在不同的层次上,并在不同层次上动态流动;为减少更新代价,根据终端移动特性的差异,对其映射信息采取不同的上报策略。分析表明该系统较好地满足了基于身份/位置分离的网络中扁平身份标志映射信息的解析要求。

Universal network is a new architecture based on identity/locator separating. A challenge from the separating is how to find a locator for a identity. This paper designed a three tiers system for mapping entries storing and resolving. Stored mapping entries in different tier with the difference frequency odds of the remote communication terminal called,and flowed from one tier to another. In order to reduce the cost of large scale mobility,policy of report to the top tier was different. It shows that the resolving system satisfies the require of universal network identity mapping resolving.
