20140016461 | PACKET RELAY DEVICE AND METHOD - When a delay between a packet relay device and a receiving terminal increases, congestion notifications are delayed, and communication quality declines. When a flow is assessed to be in a congestion state, a packet delay device overwrites, within a packet header of an acknowledgement packet for the flow which is received thereafter from a receiving terminal, a field which denotes a network congestion state with a value which denotes that a congestion state is in effect, and transmits same as an acknowledgement packet. It is thus possible to issue a congestion notification over a path from the packet relay device to the receiving terminal, eliminating a congestion notification path from the packet relay device to the receiving terminal and from the receiving terminal to the packet relay device, facilitating avoiding a decline in communication quality even if the delay between the packet relay device and the receiving terminal increases. | 01-16-2014 |
