摘要
提出了一种IP城域网的QoS解决方案,允许网络运营商在不同的虚拟拓扑中承载不同的服务流量,这种区分虚拟拓扑结构能够保证不同的QoS水平。仿真结果表明:这种QoS管理模块以增加微小的阻塞率为代价,使EF流量有了更高的传输品质。
A QoS scheme is proposed. This scheme allows network operators to provide different service traffics on different virtual topologies which can guarantee different QoS levels. The simulation results show that the QoS management module can make the EF traffic have a higher transmission quality at the cost of increasing a slight blocking probability.
