An OBS network is composed of the edge nodes and the core nodes, the service access is performed at the edge nodes of the network.
OBS网络由边缘节点和核心节点组成,网络在边缘节点处完成业务的接入。
Chapter two analyses the OBS network performance, including resource reservation, priority support and scheduling algorithm, with emphasis on their impact on the burst lost rate.
第二章是光突发交换的网络性能分析。包括了各种资源预约机制、是否支持优先级服务和各种交换结构、调度算法对突发数据分组丢失率的影响。
We can look OBS network as two networks, one is transparent optical network for transmitting data burst; the other is optical and electronic hybrid control network for transmitting burst head packet.
OBS网络可以看作两个网络的重叠:传送数据突发的纯光网络和传送突发头分组的光电混合控制网络。
We simulate the OBS network with and without wavelength converter, and contrast the result and analyze it.
对带波长变换器和不带波长变换器的网络的性能进行了模拟,并对结果进行了分析。
Actually control network is a packet switching network. So the self-similar traffics also bring negative effect to OBS network performance.
实际上,控制网络就是一个分组交换网络,因而呈自相似的业务一样会对OBS网络性能带来负面影响。
Past research work about OBS network has mostly focused on reservation scheduling, burst assembling, signaling protocol definition and performance analysis, but few on network fault management.
以往人们对OBS网络的研究大多专注在网络的资源预留调度、突发汇聚、信令协议定义和性能分析上,少有网络故障管理。
