Integrated information communications (ICS) system

摘要

To provide an integrated information communication system (ICS) 1 without using dedicated lines or the Internet, ensuring communication speed, communication quality, communication trouble countermeasures in a unified manner, wherein security and reliability in communication is ensured. The system comprises access control apparatus 2-7 for connecting a plurality of communication networks or information communication equipment (e.g. LANS), and a relay device for networking the access control apparatus. Access control apparatus receive packets 80, 82 having different user address systems ADX, ADY 80, 82 and convert these into network packets 81, 83 with network addresses conforming to a unified address system ADS for routing to destination addresses. In one embodiment each access control apparatus includes a conversion table storing user sending addresses and destination addresses together with a registered request identifier (numbers 1-4) for indicating one of intra-corporation communication (1), inter-corporation communication (2), virtual dedicated line connection (3) or, in the case of the claimed invention, registering an ICS network server as the receiving ICS network address (4). Several other embodiments are disclosed.
