receiving first rate control information for an existing TCP dataflow on a first gateway of a first wired communication trunk within a communication platform, the first rate control information indicating an available transfer rate for the existing TCP dataflow by the first wired communication trunk;

providing the first rate control information for the existing TCP dataflow from the first gateway of the first wired communication trunk to a second gateway of a second wired communication trunk within the communication platform;

generating second rate control information for the existing TCP dataflow by the second gateway of the second wired communication trunk within the communication platform, the second rate control information indicating an available transfer rate for the existing TCP dataflow by the second wired communication trunk; and

providing the lesser of the first rate control information and the second rate control information to a device within the communication platform upstream in a direction of a sending device of the existing TCP dataflow relative to the second wired communication trunk.

2. The computer-implemented method of claim 1 further comprising:

generating the first rate control information on a second gateway of the first wired communication trunk.

3. The computer-implemented method of claim 2 further comprising:

providing the first rate control information from the second gateway of the first wired communication trunk to the first gateway of the first wired communication trunk.

4. The computer-implemented method of claim 1 further comprising:

identifying a new TCP dataflow within the communication platform.

5. The computer-implemented method of claim 4 further comprising:

decreasing a rate of the existing TCP dataflow to free up bandwidth for the new TCP dataflow within one or more of the first wired communication trunk and the second wired communication trunk.

6. The computer-implemented method of claim 5 wherein the one or more of first rate control information and the second rate control information includes one or more of:

a receiver window (RWND) value associated with the existing dataflow; and

an acknowledgement delay associated with the existing dataflow.

7. The computer-implemented method of claim 6 wherein the intended recipient of the lesser of the first rate control information and the second rate control information is the sending device coupled to the communication platform.

8. The computer-implemented method of claim 6 wherein decreasing the rate of the existing TCP dataflow includes one or more of:

decreasing the receiver window (RWND) value; and

increasing the acknowledgement delay.

9. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

receiving first rate control information for an existing TCP dataflow on a first gateway of a first wired communication trunk within a communication platform, the first rate control information indicating an available transfer rate for the existing TCP dataflow by the first wired communication trunk;

providing the first rate control information for the existing TCP dataflow from the first gateway of the first wired communication trunk to a second gateway of a second wired communication trunk within the communication platform;

generating second rate control information for the existing TCP dataflow by the second gateway of the second wired communication trunk within the communication platform, the second rate control information indicating an available transfer rate for the existing TCP dataflow by the second wired communication trunk; and
