Abstract:

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.

Key words: IPv6 network, flow label domain, random early detection (RED) algorithm, priority distinguish
