Abstract
A network device determines priority of a packet based on the priority of one or more previously-received packets. The network device includes a memory, a forwarding engine, and a processor. The memory stores priority information for one or more previously-received packets. The forwarding engine generates the priority information stored in the memory. The processor determines whether to apply the priority information stored in the memory to a received packet. When the priority information applies to the received packet, the processor sends the priority information to the forwarding engine. In response to the priority information, the forwarding engine bypasses the generation of priority information for the received packet and thus cuts down on processing time in the switch and, by doing so, reduces the end-to-end latency for the packet in the network.
