Application-driven grid node architecture for intensive data services on grid based ASON

Users and applications need to own greater ability to control network resources for satisfying their requirements and new service pattern. Optical grid nodes include resource, control and switching functional. Optical grid testbed is built to verify node structure and five character of optical grid on ASON network, which involve application-driven, grid service and optical resource uniting, parallel lightpath scheduling, wide resource sharing and multi-granularity bandwidth service. An optical grid node function framework and physical implement scheme is proposed based on distributed network architecture orienting on-demand resource service. Considering the proposed optical grid scheme, corresponding control mechanism is given to satisfy the resource requirement for grid applications and realize distributed resource scheduling on demand.
