基于IPv6流标签的DiffServ实现机制

Implementation Mechanism of DiffServ Based on IPv6 Flow Label

本文在DiffServ模型的基础上,改变了路由器的功能,使用IPv6流标签字段和源地址作为关键字,在路由器中建立转发表,根据关键字转发IPv6分组,提高转发速度;同时,在DS区域使用一种流标签分配机制,避免了流标签的重复和混乱。

This text has changed the function of the router based on the DiffServ model;it puts the IPv6 flow label field and the source address as a keyword;it has established the forwarding table and for-warded the IPv6 packet according to the keywords in router. And it improves the forward speed. At the same time, it uses the distribution mechanism of flow label in the DS region and it avoids duplication and confusion of the flow label.
