Providing transport protocol within a communication network having 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 for operating a communication network comprising: receiving, at a base station, a selective acknowledgement associated with a packet transmitted from the base station and not received at a receiver due to congestion; andinvoking a congestion control mechanism in response to the selective acknowledgement. 2. The method of claim 1 wherein the selective acknowledgment comprises a flag bit indicating that the packet was not received due to congestion. 3. The method of claim 1, wherein the selective acknowledgement comprises a bit map indicating a status of each packet in a subset of packets. 4. The method of claim 3, wherein each bit of the selective acknowledgement corresponds to a sequence number of a particular packet, each bit having one value from a group comprising a first value indicating the particular packet was not received, and a second value indicating the particular packet was received without an error. 5. The method of claim 1, further comprising: retransmitting a packet not received. 6. The method of claim 1, further comprising: providing forward error correction to a header of the packet. 7. The method of claim 1, wherein a header for the packet includes a datalink header, an internet protocol header, and a transmission control protocol header. 8. A non-transitory computer readable medium storing computer program instructions for operating a communication network, which, when executed on a processor of a base station, cause the processor to perform operations comprising: receiving a selective acknowledgement associated with a packet transmitted from the base station and not received at a receiver due to congestion; andinvoking a congestion control mechanism in response to the selective acknowledgement. 9. The non-transitory computer readable medium of claim 8, wherein the selective acknowledgment comprises a flag bit indicating that the packet was not received due to congestion. 10. The non-transitory computer readable medium of claim 8, wherein the selective acknowledgement comprises a bit map indicating a status of each packet in a subset of packets. 11. The non-transitory computer readable medium of claim 10, wherein each bit of the selective acknowledgement corresponds to a sequence number of a particular packet, each bit having one value from a group comprising a first value indicating the particular packet was not received, and a second value indicating the particular packet was received without an error. 12. The non-transitory computer readable medium of claim 8, the operations further comprising: retransmitting a packet not received. 13. The non-transitory computer readable medium of claim 8, the operations further comprising: providing forward error correction to a header of the packet. 14. The non-transitory computer readable medium of claim 8, wherein a header for the packet includes a datal ink header, an internet protocol header, and a transmission control protocol header. 15. A base station for a communication network comprising: a memory storing computer program instructions;a processor communicatively coupled to the memory, the processor to execute the computer program instructions, which, when executed on the processor, cause the processor to perform operations comprising:receiving a selective acknowledgement associated with a packet transmitted from the base station and not received at a receiver due to congestion; andinvoking a congestion control mechanism in response to the selective acknowledgement. 16. The base station of claim 15, wherein the selective acknowledgment comprises a flag bit indicating that the packet was not received due to congestion. 17. The base station of claim 15, wherein the selective acknowledgement comprises a bit map indicating a status of each packet in a subset of packets. 18. The base station of claim 17, wherein each bit of the selective acknowledgement corresponds to a sequence number of a particular packet, each bit having one value from a group comprising a first value indicating the particular packet was not received, and a second value indicating the particular packet was received without an error. 19. The base station of claim 15, the operations further comprising: retransmitting a packet not received. 20. The base station of claim 15, the operations further comprising: providing forward error correction to a header of the packet.
