| Abstract: |
| 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. |
