National natural science foundation of China network ( NSFCNET ) is the first high-speed computer network test bed providing native multicast service across its backbone. 中国高速互联研究试验网是我国第一个全网支持非隧道组播协议的下一代高速互联网试验床。
The framework of the DiffServ system and the ways in which IP packets realized QoS guarantee are firstly briefed. Then the reason why it is impossible to establish momentarily an IP multicast tunnel mechanism in Cernet backbone network is analyzed. 首先简要介绍的是DiffServ体系的构成及IP包在该体系中实现QoS保证的方法,其次分析了现今的Cernet骨干网无法随时建立IP组播隧道机制的原因。
