| 摘 要： | 为了降低光交换网络的网络阻塞率和提供面向连接的服务质量(QoS),提出了一种基于时隙交换机制的光时隙交换(OTS)网络.光波长在时域内被分割成一系列固定长度的细小时隙槽以承载数据,时隙成为最基本的交换粒度,并采用控制信道和数据信道相分离的网络运行机制.相对于传统光突发交换(OBS)网络,OTS技术能提供稳定的面向连接的QoS.仿真结果表明OTS技术相对于OBS技术在降低网络阻塞方面具有显著优势.

| Abstract: | In order to decrease the blocking probability and provide the connection-oriented service in optical switching networks,a novel scheme called optical time-slot switching(OTS) is proposed,which divides each wavelength channel into a series of sliced time-slots as the basic switching granularity to accommodate data.OTS operates the separate control channel from its data channel.Therefore,OTS is capable of providing the connection-oriented service.The result shows that scheme also can improve the blocking perf... |
