Description

一种兼容 IPv4地址的通信方法、 系统及路由器
技术领域
本发明涉及身份位置分离技术,尤其涉及一种兼容 IPv4地址的通信方法、 系统及路由器。
背景技术
(一) 身份与位置分离技术
为了解决互联网核心路由器节点路由表容量快速膨胀以及 IP地址二义性 的问题, 互联网工程任务组 IETF(Internet Engineering Task Force , 简称 IETF) 近年来提出了身份与位置分离的技术, 以身份位置分离协议 (Locator and Identifier Separation Protocol , 简称 LISP)工作组提出的 LISP协议为例, 其终 端的身份标识 (Endpoint Identifier, 简称 EID)不参与 IP核心网的路由, 骨干路 由器只能看到边界接入路由器的接口路由地址 (Routing LOCator , 简称 RLOC), 而一个边界路由器可以接入大量的终端, 单独设置一个映射平面存 储终端身份 EID和路由器 RLOC的对应关系。 发往终端的报文首先需要在映 射平面中查找到其对应的边界路由器 RLOC , 然后根据 RLOC路由到目的终 端所在接入路由器。
(二)标识网 (即身份与位置分离网络)
随着网络的快速发展,现有网络的 Internet公网路由器上的路由表容量激 增, 在路由可扩展性, 网络安全保证, 移动性保证方面, 存在种种不足, 网 络架构调整势在必行, 各种路由方式不同, 寻址方式不同的异质网络融合, 互通, 成为网络发展的趋势, 在新的架构思路下, 传统网路架构下的网络标 识的身份属性和位置属性被分离开来, 新的网络分为两级架构, 接入网和路 由转发网, 接入网标识为 AID ( Access ID ) , 路由网标识为 RID ( Router ID ) 建立终端的 "身份属性" 标识 -— AID, 终端间基于 AID进行通信 建立终端的 "位置属性" 标识 -— RID, 网络间基于 RID进行路由 接入路由器负责 AID、 RID之间的转换, 终端移动时, AID保持不变, RID变化。
(三)用户身份标识的兼容性问题
随着数字化、 IP化的高速发展, 各种终端都需要身份标识。 釆用 32bit 编址的 IPv4地址总数量只有 43亿, 这远不能满足终端的通讯需求, IPv4地 址已经与 2011年 2月枯竭。为了保证给每个接入网络的终端提供一个唯一的 身份标识, 则希望终端身份标识的长度能够达到 128位。 然而互联网 /下一代 互联网中, 各种终端对 IPv4、 IPv6的兼容能力差别很大, 部分传统终端仅能 支持 IPv4地址,所以需求一种能够使普通 IPv4终端能够接入身份与位置分离 网络的标识兼容机制。
