A transport protocol is provided within a communication network that has a lossy link. The receiver distinguishes between packets received with non-congestion bit errors and packets having been not at all received due to congestion. When packets are received with non-congestion bit errors, the receiver sends selective acknowledgments indicating that the packets were received with bit errors while suppressing duplicate acknowledgments to prevent the invocation of a congestion mechanism.

1. A method comprising: transmitting, from a system including a processor, a packet to a receiver; andreceiving, at the system, a selective acknowledgement associated with the packet without receiving a duplicate acknowledgement associated with the packet, wherein the packet transmitted to the receiver has a bit error. 2. The method of claim 1, wherein the system is part of a base station, and wherein the selective acknowledgement is received from the receiver. 3. The method of claim 1, wherein the receiving of the selective acknowledgement is performed without a congestion control mechanism being performed. 4. The method of claim 1, wherein the transmitting of the packet is via a wireless connection, and wherein the bit error is associated with interference. 5. The method of claim 1, wherein the selective acknowledgment comprises a bit map with a status indicator associated with the packet. 6. The method of claim 1, comprising: transmitting, from the system, a set of packets to the receiver, wherein the set of packets includes the packet, and wherein the selective acknowledgement provides a status indicator associated with each packet of the set of packets. 7. The method of claim 1, wherein the receiving of the selective acknowledgement by the system is responsive to expiration of a time out period. 8. The method of claim 1, wherein the receiving of the selective acknowledgement by the system is responsive to a threshold number of packets being received by the receiver. 9. The method of claim 1, wherein the packet includes a header and a payload, and wherein the packet has forward error correction bits in the header and does not have the forward error correction bits in the payload. 10. A communication device, comprising: a processor; anda memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: receiving a set of packets from a system;identifying a bit error associated with a packet of the set of packets; andtransmitting a selective acknowledgement associated with the packet to the system without transmitting another acknowledgement associated with the packet to the system, wherein the selective acknowledgement is provided without invoking a congestion control mechanism. 11. The communication device of claim 10, wherein the system is part of a base station, and wherein the transmitting of the packet is via a wireless connection. 12. The communication device of claim 10, wherein the bit error is associated with interference. 13. The communication device of claim 10, wherein the selective acknowledgment comprises a status indicator associated with each packet of the set of packets. 14. The communication device of claim 10, wherein the receiving of the selective acknowledgement by the system is responsive to expiration of a time out period. 15. The communication device of claim 10, wherein the transmitting of the selective acknowledgement is responsive to a threshold number of packets being received. 16. The communication device of claim 10, wherein the packet includes a header and a payload, and wherein the packet has forward error correction bits in the header and does not have the forward error correction bits in the payload. 17. A computer readable storage device comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising: transmitting a packet to a receiver; andreceiving a selective acknowledgement associated with the packet without receiving a duplicate acknowledgement associated with the packet, wherein the packet transmitted to the receiver has a bit error. 18. The computer readable storage device of claim 17, wherein the operations further comprise providing forward error correction bits in a header of the packet without providing the forward error correction bits in a payload of the packet. 19. The computer readable storage device of claim 17, wherein the selective acknowledgement is received without a congestion control mechanism being performed. 20. The computer readable storage device of claim 17, wherein the operations further comprise transmitting a set of packets to the receiver, wherein the set of packets includes the packet, and wherein the selective acknowledgment comprises a status indicator associated with each packet of the set of packets.
