OpenNetVM Version v19.05 is a major release which introduces new experimental shared core mode and other new features. Please read the release note for a detailed list of changes: ONVM Release v19.05.

A CloudLab template is available with the latest release here: https://www.cloudlab.us/p/GWCloudLab/onvm

Summary of release:

Major updates:

  • Shared Core Mode--Allows NFs to sleep when they have no packets to process. The onvm_mgr will spawn an additional thread responsible for waking up NFs when they receive packets.
  • Major Architectural Changes--Restructure ONVM initialization sequence, better signal handling, main NF struct consolidation.
  • Advanced Rings Changes--Reworks the Advanced Ring NF support to give more control to the developers.
  • Stats Updates--Updates console stats with new information and adds the core mappings page to the web view.
  • CI Updates--Adds continuous integration to the public repo, extends CI to review PRs. Due to security concerns only authorized users are allowed to run CI.
  • LPM Firewall NF--Simple Firewall example using the DPDK LPM library.
  • Payload Search NF--Provides the functionality search for a string within a packet payload and forward/drop the packet based on the search result.
  • TTL and Packet Limit Flags--Adds TTL and packet limit functionality to both onvm_mgr and NFs.
  • NF message passing--Adds an API to allow NFs to pass messages to other NFs

Performance fixes:

  • Make Number of mbufs a constant value, this fixes our basic_monitor & pktgen benchmark performance from 7Mpps to 13.1 Mpps.

Minor improvements and bug fixes:

  • Fix all major style errors.
  • Add Compatibility Changes to Run ONVM on Ubuntu 18.04.1.
  • Add ONVM mgr web mode memory cleanup on shutdown.
  • Update Installation/Debugging/Troubleshooting docs.
  • Update the Install script to properly allocate hugepage memory.
  • Fix the Speed Tester NF packet generation to properly handle cases where all requested packets couldn't be generated.
  • Remove the custom pktgen submodule and replace it with upstream pktgen.

Testbed:

  • The aforementioned CloudLab template, and on a host with the following configuration:
