Abstract
To address the resources of the switch fabric, one embodiment of the invention provides a system and method for measuring the bandwidth of a switch fabric in addition to measuring the bandwidth in the line cards. The measured bandwidth is compared to the requirements of a routing request received in a controller. If the measured bandwidth of all resources, including the switch fabric, are sufficient to route data traffic in accordance with a predetermined SLA, then the controller reserves bandwidth in the switch fabric as well as in the line cards. Data can then be classified and queued in the line cards, and switched in the switch fabric, in accordance with the bandwidth reservations. Competing data traffic cannot rob the bandwidth in the switch fabric from the data having a bandwidth reservation. Thus, latency is controlled, and a predetermined QoS is met.
