A METHOD AND APPARATUS FOR PARSING A NETWORK ABSTRACTION-LAYER FOR RELIABLE DATA COMMUNICATION

A method and apparatus are described including parsing an abstraction-layer header, assigning a priority to a packet to be transmitted, buffering the data to be transmitted, transmitting data retrieved from a buffer via a datagram protocol, receiving a request for retransmission of data, determining if the requested data is in the buffer and retransmitting the requested data via a protocol that provides end-to-end acknowledgement of data and error recovery. A network monitor of a transmitter is connected between a network interface and a retransmission decision maker for deciding which packets to retransmit, for example, based on the assigned priority and collected network statistics. A network monitor may also be provided at a receiver for collecting current network statistics and reporting them to transmitter.
