支持网格应用的光网络控制和管理

在高能物理等科研领域有许多基于网格的科研项目,包括海量数据传输在内的网格应用对网络带宽、延迟等QoS指标等有很高的要求.传统的IP路由网络无法满足这些要求.面向连接的光网络能够较好地满足这些要求,但也面临着许多挑战.分析了科研网格应用的特点及其对光网络控制和管理的特殊要求,重点分析比较了几种现有的光网络控制和管理方式,归纳和总结了此领域尚待研究的问题,最后提出了Lambda Grid和OVPN等新的研究 方向.

Optical Network Control and Management for Grid Applications

There are many research projects based on grid in many research fields like high energy physics (HEP). Grid applications including massive data transfer have very high requirement for network on QoS parameters such as bandwidth and delay. The traditional IP routing network can not satisfy these requirements. However, the connection-oriented optical network has this capability, but it still faces many challenges. The authors firstly analyzed the features of grid applications and their special requirements for optical network control and manage- ment, and emphatically analyze several existing methods of optical network control and management. Subsequen- tly, current issues which are open are summarized. At last, some novel research issues such as Lambda Grid and OVPN are put forward.
