Abstract
To transmit a packet to be transmitted, a transmitting station specifies information indicating an expiration time for the packet. Upon receiving the packet, a receiving station analyzes the expiration time information to output data to the upper layer based on the information. This enables more efficient transmission while following the Strict Order, in a transmission/receipt system where realtime data is transfer using a collective DELAYED-ACK returned instead of ACKs for multiple packets.
