RELAY DEVICE
First Claim
1. A relay device which relays a packet which is transmitted from a first network to a second network, the relay device comprising:
- a receiver to receive the packet from the first network;
an information obtaining unit to obtain data type information for identifying a type of data which is transmitted and received by the packet;
a parameter storage unit to store a control parameter which is used for controlling communication quality in the second network, so as to be associated with a type of transfer data indicating data transferred to the second network; and
a parameter setting unit to set to the packet the control parameter which is associated with transfer data of a same type as data identified by the data type information, and to output the packet to which the control parameter is set to the second network.

Abstract
A relay device includes a receiver, an information obtaining unit, a parameter storage unit, and a parameter setting unit, and relays a packet which is transmitted from a first network to a second network. The receiver receives the packet from the first network. The information obtaining unit obtains data type information for identifying a type of data which is transmitted and received by the packet. The parameter storage unit stores a control parameter which is used for controlling communication quality in the second network, so as to be associated with a type of transfer data indicating data transferred to the second network. The parameter setting unit sets to the packet the control parameter which is associated with transfer data of a same type as data identified by the data type information, and outputs the packet to which the control parameter is set to the second network.

6. A relay device which relays a relay packet which is transmitted from a first network to a second network, the relay device comprising:
-
a receiver to receive the relay packet from the first network; an information obtaining unit to obtain data type information for identifying a type of data which is transmitted and received by the relay packet and address information which indicates a destination address and a source address of the relay packet; an object information storage unit to store a combination of a destination address and a source address of an object packet in which communication quality is controlled by the second network; a parameter storage unit to store the control parameter which is used for controlling communication quality in the second network, so as to be associated with a type of transfer data indicating data transferred to the second network; and a parameter setting unit to set the control parameter which is associated with transfer data of a same type as data identified by the data type information, to the relay packet when a combination matching the address information is stored in the object information storage unit, and to output the relay packet to which the control parameter is set to the second network.

7. A non-transitory storage medium storing a program for causing a relay device, which relays a packet which is transmitted from a first network to a second network, to execute a process comprising:
-
receiving the packet from the first network; obtaining data type information for identifying a type of data which is transmitted and received by the packet; storing a control parameter which is used for controlling communication quality in the second network, so as to be associated with a type of transfer data indicating data transferred to the second network; and setting to the packet the control parameter which is associated with transfer data of a same type as data identified by the data type information, and outputting the packet to which the control parameter is set to the second network.
