MULTI-ACCESS MANAGEMENT SERVICES PACKET RECOVERY MECHANISMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18513338 titled 'MULTI-ACCESS MANAGEMENT SERVICES PACKET RECOVERY MECHANISMS

Simplified Explanation

Packet recovery mechanisms for wireless networks aim to improve end-to-end reliability through various methods. Two main embodiments are described in the abstract:

• Packet retransmission: In this method, if a transmitter cannot find a lost packet in its transmission buffer, it sends a First Sequence Number (FSN) report to the receiver. This report notifies the receiver of the sequence number (SN) of the oldest (acknowledged) packet in the buffer. The receiver then does not report lost packets whose SN is older than the FSN.

• Network coding algorithm: This method involves using a network coding algorithm to recover lost packets. The transmitter sends a control message to the receiver that includes a coded packet to be recovered and information for decoding the coded packet.

Original Abstract Submitted

Packet recovery mechanisms for wireless networks, which improve end-to-end (e2e) reliability, are provided. First embodiments include packet retransmission between a receiver and a transmitter, wherein, if the transmitter cannot find a lost packet in its transmission buffer, the transmitter sends a First Sequence Number (FSN) report to the receiver to notify the receiver of a sequence number (SN) of an oldest (acknowledged) packet in the buffer. In response, the receiver does not report lost packets whose SN is older than the FSN. Second embodiments involve using a network coding algorithm to recover lost packets, wherein the transmitter sends a control message to the receiver that includes a coded packet to be recovered and information for decoding the coded packet. Other embodiments may be described and/or claimed.
