A network device that processes a stream of packets has an ingress front end. The ingress front end determines whether the packets are handled in a bounded latency path or in a best- effort path. The bounded latency path packets are granted a resource with a higher priority than the best-effort path packets. As the packets are processed through a number of processing stages, with processing engines, the bounded latency packets are processed within a period of time corresponding to a guaranteed rate. Resources are granted to the best-effort path packets only when the processing engines determine that the resource grant will not impact the latency bounds with respect to the first packets. |
