Claim Text:
1. A computer-readable storage medium that is not a transitory propagating signal storing computer-executable instructions for controlling a computer system to detect congestion in a network of nodes connected via connection devices, the computer-executable instructions comprising instructions of: a component that collects performance measurements for the connection devices indicating whether data is delayed at the connection devices, the performance measurements indicating number of connection device periods in which data was forwarded by a connection device during a measurement period and number of connection device periods during the measurement period in which data was delayed at the connection device; a component that determines based on the performance measurements of the connection devices whether a connection device satisfies a stall criterion; a component that determines based on the connection devices that satisfy the stall criterion whether the network satisfies a network congestion criterion; and a component that indicates the network is congested when the network stall criterion is satisfied.
