| 摘 要： | 帧中继(FR)作为一种快速分组交换技术,能够按需动态分配带宽,适于突发性,高速率和大流量的数据传输。在帧中继网络中实现语音和数据业务的融合,并保证语音业务的服务质量(QoS)问题得到人们的广泛关注。在网络仿真平台上设计了仿真实例,仿真结果表明,可以根据帧中继网络的传输特性,通过采用有效的带宽分配策略、流量控制策略、编码方案(如G.729或G.723.1)等QoS策略使得语音业务端到端的服务质量达到最优化。

| Abstract: | As a king of fast packet exchange network,Frame Relay(FR) can distribute bandwidth on demand,which is fit for paroxysmal,high speed and huge flux data transportation.It has got widely attention on the blend of data and voice in a single Frame Relay network and keep satisfying Quality of Service(QoS).Some scenarios had been designed on the network simulation platform.Simulation results show that based on the transport characters of the Frame Relay network end-to-end quality of service for voice can be optimized by using QoS polices such as efficient bandwidth distribution,traffic control and codec schemes(such as G.729 or G.723.1). |
