Interlaken Look-Aside Intel® FPGA IP

Interlaken Look-Aside is a scalable protocol that allows interoperability between a datapath device and a look-aside coprocessor for short, transaction-related transfers. A look-aside coprocessor is connected "to the side" of the datapath, and is not in-line of the main datapath of the switch, router, or other networking device. Interlaken Look-Aside is not directly compatible with Interlaken and can be considered a different operational mode.
