Abstract
The techniques discussed herein include storing a fast-path and a slow-path table in a memory associated with a programmable switch, such as a cache of the programmable switch. An offload controller may control the contents of the fast-path and/or slow-path table and may thereby control behavior of the programmable switch. The programmable may route a received packet to a gateway if the packet generates a hit in the slow-path table. If the received packet generates a hit in the fast-path table, the packet may be forwarded directly to a virtual private cloud (VPC), virtual switch thereof, and/or to a virtual machine (VM).
