Abstract
A RIP-based caching mechanism for bids in a distributed automatic route selection system for a network of PBXs. The PBXs are interconnected for propagating bid requests and replies therebetween. A cache table is maintained in each one of the PBXs for storing cached bid values for unused ones of the neighboring PBXs from whom replies have not been received responsive to a bid request. A subscribers table is also maintained in each PBX for identifying additional ones of the PBXs to whom bid value updates must be sent for updating their cache tables.
