Abstract: Flow label is introduced in IPv6 protocol, and used to provide routers for QoS implementation purpose of forwarding packets. This paper focuses on the demand of IPv6 multimedia multicast communication, and proposes an IPv6 multicast communication scheme of flow label classification providing QoS using a hybrid approach. The scheme with multimedia multicast communication is tested on IPv6 test network, and satisfactory QoS results are gotten.

Key words: IPv6, flow label, multicast communication

摘要： IPv6网络协议引入流标签概念，在路由器转发提供QoS支持。针对IPv6多媒体组播通信的需要，提出一种混合式流标签分级定义方案实现IPv6组播通信的QoS支持，在IPv6实验网上进行多媒体组播通信模拟测试，结果表明该方案能够提供满意的QoS支持。
