First Claim
1. A method of distributing congestion events by a device among a plurality of transport layer connections to dynamically alter effective bandwidth available to one or more of the transport layer connections, the method comprising:
- (a) establishing, by a device, a plurality of transport layer connections, one or more of the transport layer connections having an assigned priority;
(b) receiving, by the device, via a first transport layer connection of the plurality of transport layer connections, a first indication of network congestion;
(c) selecting, by the device according to the assigned priorities, a second transport layer connection of the plurality of connections; and
(d) transmitting, by the device in response to receiving the first indication, a second indication of a congestion event via the second transport layer connection.

Abstract
Systems and methods for dynamically controlling bandwidth of connections are described. In some embodiments, a proxy for one or more connections may allocate, distribute, or generate indications of network congestion via one or more connections in order to induce the senders of the connections to reduce their rates of transmission. The proxy may allocate, distribute, or generate these indications in such a way as to provide quality of service to one or more connections, or to ensure that a number of connections transmit within an accepted bandwidth limit. In other embodiments, a sender of a transport layer connection may have a method for determining a response to congestion indications which accounts for a priority of the connection. In these embodiments, a sender may reduce or increase parameters related to transmission rate at different rates according to a priority of the connection.
