Claim 0:
1. A method for adapting Transmission Control Protocol (TCP) traffic flows at a provider equipment (PE) node, the PE node configured to provide backhaul services to endpoint devices communicating with the PE node via respective wireless channels, the method comprising:
at the PE node, in response to a requirement to cease transmitting on wireless channels supporting current TCP connections with the endpoint devices:
(i) transmitting messages to the endpoint devices configured to cause the endpoint devices to continue transmitting currently buffered uplink (UL) data to the PE node via respective UL TCP connections using corresponding last successful TCP congestion window (cwin) sizes; and
(ii) transmitting currently buffered downlink (DL) data from the PE node 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 which are supported by more than one beam of a wireless channel, modifying a corresponding TCP slow start mechanism by increasing and an initial slow start packet size and increasing a slow start packet size increment, the increasing of the initial slow start packet size comprising multiplying a nominal slow start packet size by a number of wireless channel beams which support the respective DL TCP connection, and the increasing of the slow start packet size increment comprises multiplying a nominal slow start packet size increment by the number of the wireless channel beams.
