Internet telecommunications network digital word packet routing having digital words set exchange node marked and filtering mechanism authorizing set node packet transmission.

摘要

The packet routing system between users (10,11) over a network (20) has connected network operators (30,31) using Internet IP protocol. Each operator is connected to an exchange node (40) by a router (50,51).
