Abstract: A connection management server apparatus is arranged for the plurality of data link activated side apparatuses to systematically manage information of logical link resources to be used to connect the Internet. When a data link activating side apparatus newly calls a data link activated side apparatus, the connection management server apparatus provides information that represents a free logical link resource and a data link activated side apparatus having the logical link resource to the data link activated side apparatus that is newly called.

Abstract: In a remote access server (RAS), the number of logical link resources, which are circuit resources between the RAS and an ISP server, is set greater than the number of physical link resources, which are circuit resources between the RAS and each terminal device. In the RAS, when a particular circuit undergoes a transition to the dormant state, only the physical link resource is released to allow use by other terminal devices while the logical link resource is maintained unchanged in a connected state, whereby the loss probability is reduced without increasing the number of physical link resources.

Abstract: A data communication system includes a server, data link started side apparatus, data link starting side apparatus, and originating server. The server provides a service through a network. The data link started side apparatus performs line control between itself and the line connection destination, and performs LAN control between itself and the server through the network, thereby relaying packets between the line connection destination and the server. The data link starting side apparatus is connected to the data link started side apparatus, disconnects the line between itself and the data link started side apparatus on the basis of an MITF dial-up dormant protocol when there is no communication between itself and the server for a predetermined period of time, and shifts to a dormant state.

Abstract: Establishment of a connection between a wireless terminal and a destination terminal for data transmission. The wireless terminal is connectable to at least two communication networks each of which is connected to an internet. The destination terminal is connected to the internet. First, one of the communication networks is selected at the wireless terminal based on communication quality of the communication networks. Next, a path through the selected communication network is selected at the wireless terminal based on the network address of the destination terminal. And then a connection is established between the wireless terminal and the destination terminal through the selected path.

Abstract: In a communication terminal capable of selecting a communication medium best suited for the service settings and communicating via the selected medium, service executors include necessary applications and act as a trigger for the start of service provision. A communication controller has functions of detecting communication media, establishing connection therewith, selecting the most appropriate communication medium in response to service requests from the service executors, and performing communication. All communication between the service executors and communication nodes is performed via the communication controller, which acts as a proxy for the service executors. The communication controller sets and stores correspondence information between keywords contained in domain names and communication media to be used, between destination IP addresses and physical ports to be used, and between communication media and physical ports.
