文档介绍：基于QINQ技术的IP城域网优化方案的实现
摘要:随着使用互联网人数的增大,各种不同的业务也在增多,导致IP城域网在不断的扩大,各种安全问题也在频繁出现。为了能够对用户进行精确标识,同时使城域网具备业务识别能力,确保业务数据流的正确转发,必须对整个城域网进行扩容。
, VLAN 的基础上又增加了一层VLAN 标签,拓展了VLAN 空问,克服了目前VLAN 在城域网发展中遇到的数量不足的问题。同时,为了适应城域网的发展,QINQ封装、终结的方式也越来越丰富,为用户精确标识和业务识别提供了有效的解决方案,在运营商的业务精细化运营方面得到了越来越深入的应用。
本文对QINQ技术的原理和它在IP城域网中的应用进行了研究,介绍了QINQ技术在IP城域网中的几种常用组网方案。同时为满足更多的用户上网需求。首先,设计了VLAN 模块。通过用户接口,完成QINQ配置命令的处理,实现了以太网子接口VLAN 信息的维护。其次,通过分析VLAN 、PPPOE等模块之间的数据流和控制流,实现了三层以太子接口报文接收和发送的处理。最后,通过对现有PPPOE接口和固定IP业务的接口,在BAS和接入层上实现QINQ隔离端口功能。该方案能够应用在QINQ组网的环境中,解决了用户精确定位、业务识别等问题,增强了网络的可运营、可管理性。

Implementation of IP MAN’s optimization based on QINQ technology
Abstract:AS the using number of increases,and different kinds of business are also on the rise,they have contributed to the IP MAN expanding constantly,and made a variety of security problems emerge order to accurately identify the user and make them also have the ability to identify businesses; make appropriate triage of the different service,and ensure to forward correctly the business data flow,it is necessarily that Operator expands the entire metropolitan work.
That QINQ being used as protocol extension,and adding a layer of VLAN label based on VLAN,expands the VLAN,expands the VLAN space,and es the problem of insufficient quantity that the current VLAN encountered in MAN development. At the same time,in order to adapt the development metropolitan work,QINQ package,the ending way e more and more abundant,which provides an effective solution to precise identification and service identification for the user. Moreover,it has been more in-depth application in the operational aspects of business refinement.
The paper studies the principle of QINQ technology and its application in IP MAN, and also introduce working solutions to QINQ technology in IP MAN. Firstly, I designed the VLAN module. Through designing of the user interface,and plishing the QINQ mand processing
