Claim 9:
10. A provider equipment (PE) node apparatus, the PE node apparatus configured to provide backhaul services to endpoint devices communicating with the PE node apparatus via respective wireless channels, the PE node apparatus comprising:
processing apparatus;
network interface apparatus in data communication with the processing apparatus and configured to conduct data communications with the endpoint devices; and
storage apparatus in data communication with the processing apparatus, and the storage apparatus comprising a plurality of computerized instructions executable on the processing apparatus, the plurality of computerized instructions configured to, when executed by the processing apparatus, cause the PE node apparatus to:
based at least on a requirement to cease transmitting on wireless channels supporting current TCP connections with the endpoint devices: (i) transmit one or more messages to the endpoint devices, the one or more messages configured to cause the endpoint devices to continue transmitting currently buffered uplink (UL) data to the PE node apparatus via respective UL TCP connections using corresponding last successful TCP congestion window (cwin) sizes, and (ii) transmit currently buffered downlink (DL) data to the endpoint devices via respective DL TCP connections using corresponding last successful TCP cwin sizes; and
for each of the respective DL TCP connections supported by a wireless channel which has a determined current capacity that exceeds a nominal channel capacity of a one beam wireless channel by a threshold amount, modify a corresponding TCP slow start mechanism by selection of a larger initial slow start packet size and a slow start packet size increment.
