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.
In order to reduce the network blocking rate of optical switching network and provide connection-oriented quality of service (QoS), an optical time slot switching (OTS) network based on the time slot switching mechanism is proposed. The optical wavelength is divided into a series of fixed length Of the time slots to carry data, the time slot becomes the most basic switching granularity, and the use of control channels and data channels separated network operation mechanism.Compared with the traditional optical burst switching (OBS) network, OTS technology can provide a stable Connection-oriented QoS.The simulation results show that OTS technology has significant advantages over OBS technology in reducing network congestion.
