中文摘要：

为解决网络拥塞问题,实现网络用户的服务区分,提出了一种基于IPv6网络的可区分用户优先级的主动队列管理算法,即优先级区分RED（Random Early Detection）算法。该算法在IPv6基本报头的流标签域中标记用户的优先级,并对不同优先级的数据包进行不同的丢包处理。通过OMNeT＋＋3.2模拟仿真的实验结果表明,基于IPv6网络的优先级区分RED算法能区分用户的优先级,保证了有优先级用户的服务质量。

英文摘要：

To solve the problem of network congestion and realize the service distinguish of users,an active queue management algorithm based on IPv6 network which can distinguish the user＇s priority is proposed.It is called the priority distinguish RED（Random Early Detection） algorithm.The algorithm tags the user＇s priority in the flow label field of the IPv6 basic header.Different priorities of packets are dealt with different packet loss process.With the simulator of OMNET ＋ ＋ 3.2,the experiment results show that the priority distinguish RED algorithm based on the IPv6 network can distinguish the priority of users,and ensure the service quality of priority users.
