Abstract
In one embodiment, data segments routed through a switch fabric are identified as being either a first or a second type. First and second counters are maintained for a destination node to characterize the transmission of data segments of the corresponding type within the switch fabric. For each first-type time period, all transmitted data segments are identified as being the first type. For each second-type time period, all transmitted data segments are identified as being the second type. The first- and second-type time periods are interleaved. The first counter is reset after termination of each first-type time period and the second counter is reset after termination of each second-type time period to correct for a possible error in characterizing the transmission of the data segments within the switch fabric during the corresponding time period.
