TCP flow control optimized for networks having radio segments

摘要

Transmission Control Protocol (TCP) may be optimized for a cellular network having a radio segment. A base station may include a radio interface to connect to one or more user equipment (UE) devices and a number of queues to buffer data, incoming to the base station, from one or more servers, over TCP sessions. One or more processors may: determine state information relating to a fullness level of the queues; and transmit the state information to the one or more servers for use by the one or more servers in performing flow control with respect to the TCP sessions.

主权项

1. A method comprising:
receiving, by a device and from a base station in a cellular network, information defining a congestion state of queues at the base station, the queues being used to perform buffering for a radio interface in the cellular network, wherein the information defining the congestion state includes a plurality of binary values, wherein each of the plurality of binary values indicates whether a particular one of the queues is congested, and wherein receiving the information further comprises:
calculating a hash value based on parameters relating to a Transmission Control Protocol (TCP) session; andlooking up a particular one of the plurality of binary values based on the calculated hash values, performing flow control, by the device and for the TCP session, based on the information defining the congestion state and based on the particular one of the plurality of binary values; and transmitting, by the device, data, based on the performed flow control, to user equipment (UE) connected to the cellular network, the data being transmitted via the TCP session.
