Abstract

Data flows in a network are managed by dynamically determining bandwidth usage and available bandwidth for IP-ABR service data flows and dynamically allocating a portion of the available bandwidth to the IP-ABR data flows. Respective bandwidth requests from network hosts are received and an optimal window size for a sender host is determined based upon bandwidth allocated for the data flow and a round trip time of a segment to provide self-pacing of the data flow.

Claims

1. A method of managing data flows in a network, comprising:

dynamically determining bandwidth usage and available bandwidth for IP-ABR service data flows;

dynamically allocating a portion of the available bandwidth to the IP-ABR data flows;

receiving respective bandwidth requests from network hosts;

determining an optimal window size for a sender host based upon bandwidth allocated for the data flow and a round trip time of a segment to provide self-pacing of the data flow.
