| 摘 要： | 服务元网络体系结构采用改进树型网络拓扑结构，统一对数据类型进行划分，使用QoS区域路由方式转发数据，通过通信量整形彻底解决拥塞问题。本文着重分析介绍了服务元网络体系结构中上述QoS机制的基本原理和工作机制，并将其与现有TCP／IP网络对应机制进行了比较，得出了服务元网络体系结构的QoS机制更能满足当今分布式多媒体应用需求的结论。

| Abstract: | Being different from TCP/IP network, Service-unit based network architecture adopts several novel QoS mechanisms, which contain enhanced tree topology, unified type of data classification, QoS partial route and resource reservation in virtual circuit establishment, traffic shaping. This paper focus on introducing and analyzing the above QoS mechanisms in Service-unlt based network architecture. After comparing these QoS mechanisms to the corresponding in TCP/IP network, the conclusion that QoS mechanism in Service-unit based network can serve current distributed multimedia applications better isdrawn. |
