Integrated information communication 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 conforming to a unified address system ADS for routing to destination addresses in networks with address systems ADX or ADY. Many embodiments are disclosed. For example, in one embodiment network packets are transmitted in accordance with an assigned priority e.g. based on the protocol used.
