Abstract
A method of processing network traffic within a computing system, comprises at a first configurable logic device (CLD), receiving an ingress network packet from an external network interface, associating the ingress network packet with a timestamp indicating the time of receipt, parsing the ingress network packet to locate a link-layer checksum value and a routing-layer checksum value, determining whether the link-layer and routing-layer checksum values are correct based on the ingress network packet contents, and transmitting the ingress network packet to a second CLD via a high-speed interconnection; and at the second CLD receiving the ingress network packet, parsing the ingress network packet to locate a source address and a destination address, determining a destination and a route for the ingress network packet based at least in part on the source and destination addresses, and transmitting the ingress network packet to the determined destination via the determined route.
