QINQ技术在实验室里验证的研究

随着传输技术的发展,epon、gpon接入方式逐渐替代原有dslam。随着接入设备的改变,原有利用PPPOE+方式实现ADSL用户帐号与DSLAM端口精确绑定的方式不适合新接入方式。然而QinQ技术因其灵活、支持多业务的特点,在城域网组网中得到了广泛的应用。本文着重介绍QinQ技术的数据帧结构,svlan的特点功能,最后利用中兴设备设计实验来验证QinQ技术。

The Study of QinQ Technology

With the development of transmission technology, epon and gpon access are gradually replacing the dslam. With the change of the access devices, the original way of using PPPOE＋ to realize ADSL user accounts to bind with DSLAM port is not suitable for the new access. However, the QinQ technology with its flexibility supports a variety of business features. It has been widely used in the metropolitan area network. This paper summarizes the data frame structure of the QinQ technology and the features and functions of svlan. Also, the QinQ technology is verified in laboratory experiments by using ZTE equipment.
