Blu5 Workshop on Kernel-bypass technologies

The goal of this workshop is to present the current alternatives to build userspace network applications using kernel-bypass technologies such as DPDK, Netmap, FD.io. During the first part of the workshop I will present the foundamental concepts behind the technologies, their main APIs and the performance advantages/disadvantages compare to existing in-kernel solutions (e.g., Linux sockets, eBPF). In the second part of the talk we will start an hands-on session where we will develop a L4 proxy accelerator using DPDK and VPP/FD.io. In particular, we will also analyze some of the existing userspace TCP/IP stacks such as mTCP, OFP and F-Stack.
