Methods and apparatus for transmitting data in communications networks

A communications system comprising:

• a cable modem termination system (CMTS) including:
• a memory, said memory including an uplink buffer and a downlink buffer;
• and
• a first processor that controls the CMTS to perform the following operations:
• establishing a first Transmission Control Protocol (TCP) session between a wireless base station and the CMTS;
• receiving via the first TCP session at the CMTS a first set of TCP data packets from a cable modem located on a communications path between the wireless base station and the CMTS, said first set of TCP data packets having been sent by the wireless base station;
• and
• determining, by the CMTS, whether to send an Acknowledgement (ACK) message or a Negative Acknowledgement (NACK) message to the wireless base station for the entire first set of TCP data packets based on verifying a subset of TCP data packets of the first set of TCP data packets.

A non-transitory computer readable medium including a first set of computer executable instructions which when executed by a processor of a cable modem termination system (CMTS) cause the CMTS to perform the steps of:

• establishing a first Transmission Control Protocol (TCP) session between a wireless base station and the CMTS;
• receiving via the first TCP session at the CMTS a first set of TCP data packets (also referred to as TCP segments) from a cable modem located on a communications path between the wireless base station and the CMTS, said first set of TCP data packets having been sent by the wireless base station;
• and
• determining, by the CMTS, whether to send an Acknowledgement (ACK) message or a Negative Acknowledgement (NACK) message to the wireless base station for the entire first set of TCP data packets based on verifying a subset of TCP data packets of the first set of TCP data packets.
