Abstract
The invention herein described consists of a method to compute in a end-to-end fashion the sending rate of data, audio and video flows over a packet switching network such as the Internet Protocol Network. The sending rate is computed as a function of the data sent in the recent past and as a function of a probing function w(t) that is dynamically set by taking into account signals of network congestion and the network changing available bandwidth.
Claims17
A method to compute a sending rate r(t) of data, audio or video over a packet switching network in which a user of a client/server machine connects to a client/server machine, comprising:
- computing the sending rate r(t);
- computing samples B(t) of available bandwidth by taking into accounts the flow of packets received by the client, if the routine is implemented at the receiver side, or by taking into accounts acknowledgment packets received by the sender, if the routine is implemented at the sender side;
- computing the available bandwidth {circumflex over (B)}(t) by filtering the samples B(t) of available bandwidth using a discrete time low-pass filter.
A method according to any of preceding claims, wherein it is implemented in TCP congestion control.
