Method and apparatus for network congestion control using queue control and one-way delay measurements

A method for congestion control in a network comprising:

• determining throughput of the network;
• determining if a current α value is associated with the throughput;
• incrementing the α value when the current α value does not correspond to the throughput.

A method for congestion control on a network comprising:

• determining the forward queueing delay (FQD) of a message sent on the network;
• adjusting the queueing delay of the network using FQD.

A method for congestion control on a network comprising:

• defining a backlog equilibrium condition that includes a utility function u(x) and a number of data flows N;
• defining u(x) so that as N increases, the backlog increases at a lower rate.

A method for congestion control on a network comprising:

• computing an equilibrium loss probability p;
• computing an equilibrium queueing delay q;
• driving a function of p and q towards a pre-determined target value.

A method of detecting route changes in a network comprising:

• incrementing an a value by Δα;
• determining a change in round trip time (ΔRTT) after incrementing the a value;
• defining a route change as occurring when the ΔRTT/Δα is close to zero.
