Abstract
The present invention is applied, for example, to a gateway apparatus in a home network. The content of a command transferred according to a control protocol is changed, if necessary, and the command is relayed.
Claims11
A data transfer apparatus connected between first and second networks, for transferring designated information between the first and second networks, characterized by comprising:
- data input-and-output means connected to first and second terminals belonging to the first and second networks, respectively, through the first and second networks;
- storage means for storing a parameter used for relay processing of information to be transmitted and received between the first and second terminals;
- and
- data processing means for executing processing related to relaying of data transfer performed according to a transport protocol, the data being transmitted and received between the first and second terminals, and of command transfer performed according to a control protocol for the data transfer performed according to the transport protocol;
- and
- characterized in that,
- when the data input-and-output means receives a command sent according to the control protocol, the data processing means changes a parameter related to the transport protocol in the command, sends the command having the changed parameter, sent according to the control protocol, through the data input-and-output means, and stores the changed parameter related to the transport protocol in the storage means, and
- when the data input-and-output means receives data sent according to the transport protocol, the data processing means applies relay processing to the data according to the parameter stored in the storage means.

A data transfer method for transferring designated information between first and second networks, characterized by comprising:
- a control-protocol relay step of applying relay processing to a command transmitted and received according to a control protocol between first and second terminals belonging to the first and second networks, respectively, and of setting a parameter used for a transport protocol according to which data is transferred between the first and second terminals, according to a parameter in the command;
- and
- a transport-protocol relay step of applying relay processing to data transfer performed according to the transport protocol between the first and second terminals, according to the parameter specified in the control-protocol relay step, and
- characterized in that, in the control-protocol relay step, a parameter related to the transport protocol and disposed in the command sent according to the control protocol is changed, and the changed command sent according to the control protocol is output.
