PACKET RELAY APPARATUS AND CONGESTION CONTROL METHOD
First Claim
1. A packet relay apparatus relaying a packet exchanged between communication apparatuses with a connection established, the packet relay apparatus comprising:
- a buffer to store a packet selected from among arrival packets so that a transfer of the selected packet is to be suspended; and
a congestion controller to monitor, after the storage of the packet on the buffer, a packet passing through the packet relay apparatus, and causing the packet, stored on the buffer, to be transmitted at a timing responsive to a passage status of a packet having a same connection as the connection of the packet stored on the buffer.
