Estimating the term…
Predictions of congestion conditions for a traffic stream in a communication network are applied to modify an initial congestion window size for the traffic stream; and dynamic bandwidth control is thereafter applied to the traffic stream. This dynamic bandwidth control may include modulating inter-packet bandwidths of the traffic stream according to a capacity of a bottleneck in a communication path through which the traffic stream passes in the communication network. The predictions of congestion conditions may be based on monitoring packet losses and/or round trip times within the communication network for a selected period of time. The monitoring may be performed on at least one of a traffic stream-by traffic stream basis, a connection-by-connection basis, a link-by-link basis, or a destination-by-destination basis.
A method, comprising:
A method comprising:
A communication network comprising one or more communication paths between one or more content sources and one or more clients, at least one of the communication paths including a control node configured to set an initial congestion window for a traffic stream transmitted over the at least one communication path according to predicted congestion conditions for that traffic stream, increased up to an advertised window size of a client receiving the traffic stream and to rate limit the traffic stream to an effective bandwidth associated with a potentially congested bottleneck in the at least one communication path over which the traffic stream is transmitted, wherein rate limiting the traffic stream acts as a back up to ensure that congestion is avoided between periods of setting the congestion window size.
