Abstract
A resource constrained routing method in active networks having a plurality of active nodes for servicing client requests includes capturing a client service request by the active node coupled to the requesting client and generating a routing directive by updating an upstream pointer to indicate another active node to actually process the service request and a downstream pointer to indicate to the processing active node the requesting client. The routing directive generation is based upon the resource status synchronization table at the capturing active node that contains information about the capabilities of all of the other active nodes in the network. The resource status synchronization table is updated on an event basis when the processing active node accepts responsibility for processing the service request and again when the processing active node completes the service request in order to maintain coherency between all of the active nodes. The result is an end-to-end data flow channel with the requesting client.
