Performance Interface eXtractor (PIX)

This repository hosts PIX, a tool to automatically extract performance interfaces from NF code. PIX was published at NSDI'22 (paper).

Organization

Subdirectories have their own README files.

  • dpdk-nfs - contains the set of NFs written using Intel's DPDK that we extracted performance interfaces for.
  • ebpf-nfs - contains the set of NFs written using the eBPF XDP framework that we extracted performance interfaces for.
  • install.sh - script to install all of PIX's dependencies
  • install - patches and config files for PIX's dependencies

Getting Started

The install.sh script installs all of PIX's dependencies. Run ./pix/install.sh from the directory containing PIX.

To list all the dependencies, run ./pix/install.sh --help

To extract performance interfaces for individual NFs, please refer to the READMEs within the respective subdirectories.

Other information

  • All code in this repository was tested on Linux kernel versions <= 4.15.
  • To run the DPDK NFs (but not necessarily to extract performance innterfaces), you need to set up hugepages for DPDK; see the DPDK documentation.
  • At several points in the code, pix will be referred to as bolt. This is because internally at DSLAB, pix was a successor to the bolt tool that extracted performance contracts from NF code (bolt source)
