ASON中的多粒度光交叉连接技术

自动交换光网络是光传输技术的下一个发展方向，通过引入智能化的控制平面，使光传送网能提供连接的动态建立和拆除。多粒度光交叉连接设备是自动交换光网络中传送平面的关键设备，直接为自动交换光网络提供光通道连接功能。该文介绍了多粒度光交叉连接设备的两种结构方案，并对两种方案进行比较。分析了多粒度光交叉连接设备相对常规光交叉连接设备的优点，以及对自动交换光网络中控制平面的功能支持。最后介绍了多粒度光交叉连接设备网络的波长绑定和路由算法的研究进展及发展趋势。
关 键 词 自动交换光网络; 多粒度光交叉连接; 波带

Abstract ASON is the next step in the progress of optical trandmission technology. It provides the ability of connection’s dynamic setup and release by introducing the intelligence contol plane. The multigranular optical cross connect is the key equipment in ASON.It provides the connection function for optical channel.The two structure of MG-OXC are introduced and compared in this paper.The advantage of MG-OXC comparing to the ordinary OXC is introduced . It’s ability to support the control plane of ASON is also introduced.The evultion and trend of waveband and routing algorithm research are introduced in the last part.
Key words ASON; MG-OXC; Waveband
