Abstract

See full text

A method for communication employs a plurality of gatekeepers and involves receiving at a first gatekeeper a request for information. If the information is not known by the first gatekeeper, a request is sent via a gatekeeper-level path to a second gatekeeper for the information. If the information is known by the second gatekeeper, it is returned along the original path to the first gatekeeper.
