Relay server, relay server method and relay server computer program product

摘要

Herein disclosed a relay server (100) comprising: protocol conversion means (110, 120, 130) for receiving an input data signal in an input-side protocol transmitted by an output entity (220), converting the input data signal in the input-side communications protocol into an output data signal in an output-side communications protocol applicable to an input entity (230), and transmitting the output data signal in the output-side communications protocol to the input entity (230); and control means (140, 150) for receiving terminal protocol information indicative of the output-side communications protocol applicable to the input entity (230) from the input entity (230) and controlling the protocol conversion means (110, 120, 130) in response to the terminal protocol information, thereby making it possible for an output entity and an input entity to receive and transmit data signals between them regardless of whether the output entity and the input entity share the same communications protocol or not.
