摘要

提出一种新的基于区域编码的标记交换网实现方案

描述了标记交换网的组成、工作原理、体系结构及主要特点.该方案将整个互联网按地理区域进行划分

并为每个区域分配唯一的长度固定的区域编码

在链路层帧头和IP分组头之间插入相应的区域编码标记

则分组在区域标记交换网中传输时

标记交换机将定长的目的区域编码作为分组的转发标记完成分组的转发.理论分析和仿真结果表明

区域标记交换网通过采用分层区域编码结构

极大地减少了骨干交换机的路由表项数

降低了路由存储空间和路由查找复杂度

同时也大幅度地降低了维护路由表项的处理开销和链路传输开销

使网络具有良好的扩展性.该方案能有效地克服现有互联网地址空间不足、路由表过大、不能提供良好的服务质量等缺点

简化骨干网交换设备的实现复杂度

提高网络的吞吐率

并能提供良好的服务质量保证.

Abstract

A new label switching scheme based on regional code is proposed.The framework

operational principle and main characteristics of the system are described.The scheme divides the whole Internet into regions

and every region is assigned a unique fixed length regional code.The corresponding regional code label is inserted between data link frame header and IP packet header by accessing label switching when packet accesses label switching network.The core label switching identifies destination regional code of packet to follow the packet in label switching network only.It is showed by theoretical analysis and simulation that the network can greatly reduce the number of routing entries in routers

and largely lessen link bandwidth and processor overhead for maintaining these entries.The scheme can effectively overcome the Internet shortcoming of IPv4 address space exhausted

simplify the complexity of the implementation of the core switching

enhance the system throughput

and provide good QoS.
