Selective acknowledgement framework for high-performance networks

According to examples, a selective acknowledgement framework may be implemented within a communication system for efficient communication of acknowledgement packets. A plurality of data packets generated from a message may be transmitted as a segment of data packets to a receiver which generates an acknowledgement packet for the segment of data packets. A compact format of acknowledgement (ACK) or negative acknowledgement (NACK) for the segment of data packets may be implemented in the acknowledgement packet via bits of a selective acknowledgement bit vector. Based on the other values also conveyed in the acknowledgement packet, the transmitter may identify those data packets that were properly received and the data packets that need to be re-transmitted.
