NetFPGA Training School

The NetFPGA is an open source hardware and software platform designed for research and teaching. The need for high-speed and software programmable networks requires suitable hardware platforms for developing and testing novel network solutions. The increasing interest for the design of high-speed programmable dataplanes (such as the barefoot switches) also push toward the adoption of hardware prototype platforms where implement and verify dataplane architectures. Furthermore, the use of hybrid solutions in which FPGA and commodity servers represent another interesting research topic. In all these research fields, the NetFPGA platform is an ideal candidate prototype and develop efficient solutions. However, using NetFPGA can be difficult for network engineers that usually are not familiar with many of the hardware design concepts behind the development of FPGA systems. In this training school, we aim to show the main characteristics of the NetFPGA and some useful applications developed on top of it. Moreover, we will present the main concepts of FPGA based designs and we will run a series of labs exercise where the students will design,verify and implement on a SUME NetFPGA several hardware designs.
