Abstract
An information handling system includes a plurality of sequentially connected units including a first unit, a second unit and a third unit. Packets of information flow from the first unit directly to the second unit and then to the third unit, and each of the plurality of units provides a respective dynamic output indication indicating if that unit output a packet. The information handling system further includes a control unit that determines, utilizing all of the plurality of dynamic output indications, packet buffering capacities of the plurality of units, and guaranteed packet flows between adjacent ones of the plurality of units, if the first unit can output a packet directly to the second unit without packet loss. In response to this determination, the control unit outputs a control signal to the first unit.
