Rubber, Meet Road: X-Project Collaboration Demos at ONS

  • Linux Foundation Networking (LFN) was launched earlier this year to increase collaboration and operational efficiencies across open source networking projects. While each technical project retains its technical independence and project roadmaps, the LFN structure integrates governance, improves operational efficiencies, and simplifies member engagement. It also provides a vehicle to strengthen and develop the myriad of cross-project collaboration nexus points across the open networking stack. Nowhere is this more clear than in the demo lineup for the LFN booth at Open Networking Summit where several demos will incorporate the work of multiple networking projects and peel off the line to show the integration, automation, and acceleration made possible by open source.

    Founding LFN projects, OpenDaylight, ONAP, OPNFV are all represented while PNDA and SNAS are considering a multiple-project analytics demo for Open Networking Summit Europe this fall. A great example of inter-project collaboration is the Cross-Community Continuous Integration (XCI) demo that establishes a new framework for telco use cases that simplifies end-to-end testing and integration by giving developers full control over components and versions to use while creating various combinations of an integrated stack. End users will also benefit from learning how the OPNFV Doctor project has built something completely new in open source with a framework to perform infrastructure maintenance and upgrades with zero virtual network function (VNF) downtime by scaling down applications and utilizing capabilities of the underlying compute nodes with OPNFV software running on OCP hardware.

    Cloud-native, containerized VNFs are an industry hot topic and will be on display in multiple demos. Folks from the project will show how to create cloud-native VNFs using Ligato and compare their performance and scale to VNFs deployed in other environments. Containers are a crucial vehicle on the path toward edge computing and the folks from the Container4NFV project in OPNFV will present a high-performance container cloud solution for edge computing on the Arm platform.

    Automation and orchestration will also take center stage as ONAP Amsterdam will be used to design, orchestrate and manage VoTLE — a complex end-to-end real-world service composed of multiple VNFs from different vendors based on the ETSI NFV architecture. ONAP and Kubernetes will also be demoed together in the CNCF booth, showing the best of network automation and cloud native orchestration by enabling ONAP deployments to any public, private, or hybrid cloud.

    Listed below is the full networking demo lineup:

    • NFV Use Cases Deployed and Tested by OPNFV XCI (OPNFV, OpenDaylight, Open vSwitch, OpenStack)
    • ONAP Amsterdam VoLTE Use Case (ONAP)
    • Accelerated Cloud Native VNFs in Kubernetes with and Ligato (, k8s, Ligato, Contiv)
    • OPNFV Verified: NFVI Platform Verification (OPNFV)
    • Containerized VNF Running on High-performance Kubernetes for Edge Computing on Arm Platform (OPNFV, k8s, DPDK)
    • Infrastructure Maintenance & Upgrade: Zero VNF Downtime with OPNFV Doctor on OCP Hardware (OPNFV, OCP)
    • Networking for Hybrid Cloud and DCI with OpenDaylight EVPN (OpenDaylight)
    • World’s Tiniest OPNFV Pod (OPNFV)
    • Intro to the CNCF Cross-cloud CI project (k8s, ONAP) In the CNCF Booth

    To all the demo managers down in pit row with the greasy hands, thanks for your hard work pulling these together. To everyone else, we’ll see you at the race.

Tmux Commands

screen and tmux

A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

It should be noted that this is no where near a full feature-set of either group. This - being a cheat-sheet - is just to point out the most very basic features to get you on the road.

Trust the developers and manpage writers more than me. This document is originally from 2009 when tmux was still new - since then both of these programs have had many updates and features added (not all of which have been dutifully noted here).

  • Use the same script for updating/ upgrading

    Make sure to change the versions to the latest releases:

    #!/bin/bash set -e bpcver=4.2.1 bpcxsver=0.57 rsyncbpcver=

    Scroll through the script, know what you are doing.

    Uncomment the upgrade section(s) and comment out the install section(s)

  • Again running smartctl after all is said and done:

    smartctl --all /dev/sda

    Yet an old drive in itself, I run the wheels off of them, and monitor regularly as anyone should.
