Low Latency Networking Device Using Header Prediction

摘要

A network device receives a packet that includes a plurality of header fields. The packet is parsed to sequentially obtain the plurality of header fields. One or more header fields not yet available at the network device are predicted based on one or more header fields that are available at the network device. A network processing decision is generated for the packet based on the predicted one or more header fields and the one or more header fields that are available at the network device.

主权项

1. A method comprising:
at a network device, receiving a packet that includes a plurality of sets of header fields; parsing the packet to sequentially obtain the plurality of sets of header fields; predicting, based on a received first set of header fields made available at the network device, a predicted second set of header fields before a received second set of header fields is made available at the network device; and generating a network processing decision for the packet based on the first set of header fields and the predicted second set of header fields before the received second set of header fields is made available at the network device available at the network device.
