Abstract: The integrated information communication system is comprised of an access control apparatus for connecting a plurality of computer communication networks or information communication equipment to each, and a relay device for networking the aforementioned access control apparatus. The system has functions for performing routing by transferring information by a unified address system and by changing address at the access control apparatus, and is configured such that the aforementioned plurality of computer communication networks or information communication equipment can perform communications in an interactive manner. The integrated information communication system ensures communication speed, communication quality, communication trouble countermeasures in a unified manner, without using dedicated lines or the Internet, wherein security and reliability in communication is ensured without change of a private address system.

Abstract: An integrated information communication system capable of improving information security is provided, in which an IP packet is detected which is sent from an external area toward either an operation management server or a relay apparatus, the detected IP packet is not entered inside the integrated information communication system in order to reduce such a chance that the operation management server and the relay apparatus are unfairly attacked. Also, such an IP packet is detected and discarded, which violates an address application rule established so as to keep secret of a communication company network. An address which is applied to either an operation management server or a relay apparatus employed in the integrated information communication system is sectioned, or classified as an “address which is not opened outside network” with respect to an external area of the communication system. A packet filter is installed in an address control apparatus.

Abstract: To provide an integrated IP network containing therein a plurality of separated IP networks with a variety of characteristics, such as IP telephone network, IP video network, IP electronic text network, best effort network, IP data multicast network and IP-based TV broadcast network. In the integrated IP network there are virtually installed a plurality of IP networks with various features, such as IP telephone network, IP video network, IP electronic text network, best effort network, IP data multicast network and IP-based TV broadcast network. An address management table is set in each of the network node devices installed at input points through which the integrated IP network is accessed from outside. The address management table is registered beforehand with terminal addresses and port numbers identifying the application programs (AP) in the terminal.
