DPDK enhanced VNF DPI over an SR-IOV accelerated network

The Deep Packet Inspection (DPI) use case was used, to demonstrate the benefits of using SR-IOV enabled devices with DPDK to support performant Virtual Network Function (VNF) deployments.. Performance evaluation of VNF versions using LibPCAP, SR-IOV and DPDK have been carried out. The results demonstrate that significantly higher packet throughput performance can be achieved when using SR-IOV and DPDK in unison in comparison to packet processing with the native Linux kernel network stack.

This work is presented in detail in the conference paper:

Enhancing VNF performance by exploiting SR-IOV and DPDK packet processing acceleration, M.A. Kourtis, et al., Network Function Virtualization and Software Defined Network (NFV-SDN), 2015 IEEE Conference on, At San Francisco

A VPP plugin utilizing Intel® QuickAssist Technology to perform hardware assisted compression operation.

The Intel® QuickAssist Technology is a powerful hardware based solution to perform crypto and compression operations. QuickAssist offloads the operations from CPU to the 89XX communications chip. A VPP plugin that utilizes the QuickAssist feature for data compression can be used as a graph node and can be called by the packet processing graph.

Acceleration Enhancements for DPDK currently already has the ability to perform cryptographic operations either by software or hardware depending on the capabilities of the processor that the code is running on. This project will be adding compression to the Acceleration Enhancements for DPDK and at this time limit to hardware based only while later only add in software based compression similar to the crypto counter part.

This VPP plugin will use this compression feature that will be added to the Acceleration Enhancements for DPDK to perform the compression operation.
