新一代互联网的定位符与标识符分离方案

摘要

为了实现新一代互联网定位符(identifier,ID)和标识符(locator,Loc)的分离,提议一种解决方案:结合分布式哈希表(distributed Hash table,DHT)技术和域的层次结构设计ID/Loc映射系统；采用分层聚合方法设计路由体系结构,并定义定位符和路由算法.分析了该方案如何满足对映射信息的快速查询和更新、地址重分配、多家乡的支持、快速路由等新一代互联网的要求.通过C++编写仿真程序,分析路由算法的执行时间和映射系统的查询时间,证明了该方案的可行性和算法的良好收敛性.%To implement the identifier (ID) /locator (Loc) separation for the future network, a resolution is presented that design a (distributed hash table) DHT-base ID/Loc mapping system and combine the Hierarchical and aggregation method to design the routing architecture, locator, and routing algorithm. By analyzing the resolution, it can satisfy the needs of the future network, such as, updating and querying the ID/Loc Information quickly, reassigning the address, supporting multi-homing, routing quickly and so on. An emluator is designed by C++ to simulate the resolution's algorithms. By analyzing the executing time of routing algorithm and querying algorithm, the result validates the feasibility of the resolution and shows that this algorithm is better than other algorithms in convergence rate.
