Abstract
Technologies for determining a root of congestion include a network switch. The network switch is to operate arbiter units in at least one upstream stage at a packet transfer rate that is greater than a packet transfer rate of an arbiter unit in an output stage, determine whether an input buffer of a remote network switch in communication with the output stage has sustained congestion over a first predefined time period, determine whether an output buffer of the arbiter unit in the output stage has sustained congestion over a second predefined time period, and determine, as a function of whether the input buffer of the remote network switch has sustained congestion and whether the output buffer of the arbiter unit in the output stage has sustained congestion, whether the network switch is a root of congestion.
