AI Technical Summary

Technical Problem

Existing network systems face challenges in preventing access by other terminals to a terminal in use without reducing the bandwidth of a dedicated peer-to-peer path, especially in advanced communication networks utilizing optical fiber technologies like multicore fibers and wavelength division multiplexing.

Method used

Implementing a control unit in network devices that manages connection requests and responses, recognizing terminal usage based on stored or received connection information, and controlling messages to prevent access attempts without reducing bandwidth, and facilitating mediation through network nodes without direct terminal communication.

Benefits of technology

Effectively prevents unauthorized access to terminals in use while maintaining dedicated peer-to-peer path bandwidth, allowing seamless connection management and user notification of terminal availability.

Abstract

This invention satisfactorily prevents another person from accessing a terminal that is in use, without reducing the band of a dedicated peer-to-peer path for the terminal that is in use.　A control unit controls: processing for receiving a request by a first terminal to connect to a second terminal; and processing for, if the second terminal is in use, transmitting to the first terminal a notice that connection is not possible. For example, the control unit recognizes that the second terminal is in use on the basis of connection information stored in a storage unit, or on the basis of connection information transmitted from the first terminal and received from another network device that transmitted a request to connect to the second terminal.
