Abstract:

Network resource coordinated scheduling strategy supporting multichannel transmission is presented to implement highperformance optical network with high bandwidth and flexibility for distributed services under the researching of optical grid architecture. The divisible load theory is introduced into the strategy to divide data or bigbulk file. The parallel multiple wavelength reservation is combined with the applicationdriven mode. An optical grid testbed is designed to verify the feasibility of the coordinated scheduling strategy. The performance of multichannel transmission is analyzed through an example of the distributed computing about electric power flow. Experiment shows that the strategy can provide flexible resource allocation with optimizing the transmitting performance of distributed service and using efficiency of optical network resource. 

Key words: optical grid, resource scheduling, grid service, lightpath reservation
