Abstract:
A caching system for use in network devices for reducing the processing burden of call request messages received by a second network device from a first network device, said caching system comprising:a first cache in said first network device, said first cache for storing a plurality of first cache indexes, each first cache index having a call group data set associated therewith;a second cache in said second network device, said second cache for storing a plurality of second cache indexes, each second cache index having processing results data and a plurality of third cache indexes associated therewith;means for generating and storing in said first cache a new first cache index for each call request having a unique call group value, and for sending said new first cache index with said call request to said second network device;means for determining whether said call request has been previously received and if so, retrieving from said second cache the processing results data corresponding to the first cache index for said call request; andmeans for storing processing results data in said second cache in the event said call request is the first to be received having such a call group value.
