System for establishing communication

Abstract

A system to establish communication that reduces the time to establish inter-terminal communication and reduces load on the server during establishment of communication between host terminal and client terminal, during inter-terminal communication after establishment of communication and during reconnection. A system to establish communication includes a host terminal, at least one client terminal, and a server that mediates their communication. The host terminal includes host-side communication requester to send host terminal information to the server and host-side manager to manage client terminal information of individual client terminals. The client terminal includes client-side communication requester to send client terminal information to the host terminal and client-side manager to manage host terminal information. The system is configured so that, after the host terminal makes a direct session start request to the client terminal based on the client terminal information, communication is established between the host terminal and the client terminal.
