Abstract
Presented herein are techniques for performing packet forwarding or routing using a pipeline of a plurality of tiles. A method includes receiving a packet, parsing the packet to generate a vector, passing the vector to a first tile dedicated to a first type of lookup, performing a lookup in the first tile, storing a result of the first type of lookup in the vector to obtain a first updated vector, passing the first updated vector to a second tile dedicated to a second type of lookup, performing a lookup in the second tile, storing a result of the second type of lookup in the vector to obtain a second updated vector, and transmitting the packet from the network routing device via an output port thereof selected based on the second updated vector.
