Methods, systems, and computer readable media for controlling Tx and Rx throughput over TCP

A system for controlling transmit and receive throughput over TCP, the system comprising:

• a first node having a network interface for transmitting TCP packets to and receiving TCP packets from a second node over a packet network, the first node having a throughput control module for:
• splitting a target TCP packet throughput across a plurality of consecutive time slots, each slot having a target throughput value, wherein the target throughput value for each of the time slots is apportioned among one or more active sessions;
• determining whether an achieved throughput value for a current slot matches the target throughput value for the current slot;
• and
• upon a determination that the achieved throughput value for the current slot does not match the target throughput value for the current slot, adjusting the target throughput value for at least one of the current slot and a subsequent slot;
• wherein the throughput control module controls transmit throughput from the first node to the second node by transmitting TCP packets from the first node to the second node according to the target throughput value for the current slot and wherein the throughput control module controls receive throughput from the second node to the first node by dynamically calculating an advertised receive window size according to the target throughput value for the current slot and communicating the advertised receive window size to the second node.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

• splitting a target TCP packet throughput across a plurality of consecutive time slots, each slot having a target throughput value, wherein the target throughput value for each of the time slots is apportioned among one or more active sessions;
• determining whether an achieved throughput value for a current slot matches the target throughput value for the current slot;
• upon a determination that the achieved throughput value for the current slot does not match the target throughput value for the current slot, adjusting the target throughput value for at least one of the current slot and a subsequent slot;
• controlling transmit throughput from the first node to the second node by transmitting TCP packets from the first node to the second node according to the target throughput value for the current slot;
• and
• controlling receive throughput from the second node to the first node by dynamically calculating an advertised receive window size according to the target throughput value for the current slot and communicating the advertised receive window size to the second node.
