OpenSwitch (OPX) Delivers Enterprise-Grade, Deployment-Ready Solution for Composable Networking



  • New Release of Open Source Network Operating System Enhances Manageability, Automation, and Extends Hardware Compatibility as Inocybe Technologies, Metaswitch and Verizon Connect Join Community

    SAN FRANCISCO – June 21, 2018OpenSwitch, a Linux Foundation project with the mission of delivering a turn-key switching software solution based on the OPX open source Network Operating System (NOS), today announced availability of the OPX 2.3 software release, delivering an enterprise-grade composable networking solution for white box switches. OPX 2.3 brings important iterative updates that supplement networking, instrumentation and management features with enhanced automation capabilities, and extends OPX compatibility to two new families of hardware platforms.

    Architected as a scalable, cloud-ready, agile solution, the open source OpenSwitch software implements flexible infrastructure to enable both network operators and vendors to rapidly on-board premium open source premium NOS applications. Backed by industry leaders such as Dell EMC and Metaswitch, OPX 2.3 supports a rich set of L2/L3 networking features that are compatible with a wide variety of 10G, 25G, 40G and 100G hardware platforms from multiple vendors.

    Specific feature enhancements include SNMP support, upgradability via standard Linux apt tools, and persistent configuration. OPX 2.3 brings support for remote authentication and remote access control by adding Remote Authentication Dial-In User Service (RADIUS) and Terminal Access Controller Access-Control System Plus (TACACS+) features. Support for these features will allow network operators to maintain user profiles and access logs in a central database that all remote equipment can share, and providing better security and control from a single administered network point. OPX 2.3 also adds support for two new platforms from Dell EMC – S5148F-ON, based on Cavium XPliant programmable ASIC and S4200-ON, based on Broadcom Qumran ASIC – extending OPX’s hardware compatibility list to include more than a dozen 10G, 25G, 40G and 100G switches from multiple vendors.​

    The number of quickly growing application offerings compatible with OpenSwitch is growing, and includes, among others:

    • Apstra AOS® Intent-Based Networking software to increase network service agility, reduce infrastructure TCO, and simplify how data center networks are built and operated.
    • Metaswitch CNP-Base-OPX package: a complete suite of layer 2 and layer 3 control plane protocols and management interface options
    • FRRouting: open-source IP routing suite for Linux
    • CaviumTM: PacketTrakkerTM, programmable telemetry suite
    • Broadcom: BroadviewTM, telemetry application
    • InMon: hsflowd, a community developed flow-based telemetry application
    • Inocybe community-developed open networking solution utilizing OpenDaylight

    “The ability to install and operationalize individual protocol stacks as applications or micro-features facilitates the design of cost-conscious, composable networks (based on a mixture of best-of-breed hardware and software) that reduce failure domains and improve performance,” said Alley Hasan, OpenSwitch Project Governing Board chair. “The OpenSwitch community is committed to continue developing viable, turn-key solutions for data center operators, as well as for service provider edge and core architectures.”

    The project ecosystem surges ahead as well, recently welcoming Inocybe Technologies, Metaswitch and Verizon Connect as new project members. OPX’s expanding member base includes contributions from both user and vendor communities, all collaborating to advance the introduction of innovative, production-ready, turnkey composable networking solutions.

    “We welcome the growth and increased community in OpenSwitch and are excited about this new release, which helps move the disaggregation forward,” said Arpit Joshipura, general manager, Networking, The Linux Foundation. “OpenSwitch is one of the key network operating systems that forms the basis of broader harmonization across the white box NOS stack.”

    The OpenSwitch composable networking model empowers the creation of completely customizable infrastructures based on modular components. OPX empowers operators the option to deploy the right combination of hardware platform, network operating system and individual software components to best suit their specific use case. OPX is currently deployed in production networks, including those of Tier 1 Service Provider infrastructures, providing reliable and scalable solutions for greater agility that can significantly reduce both CapEx and OpEx expenses.

We are happy to collaborate with Cavium and apply its Packet Trakker programmable telemetry technology.”

    Verizon Connect: Rick Davis, Infrastructure Architect and DevOps Leader
    “In early 2016 we launched an initiative to modernize our application stack in order to leverage the latest micro service, messaging, and database frameworks, and we needed a next- generation infrastructure platform to support it. Choosing OpenSwitch (OPX) allowed us to achieve both our business and engineering goals. OPX helped us increase our development velocity, thus reducing OpEx, while also helping reduce CapEx by using cost conscious open source software, without having to compromise commercial support. Our highly scalable, extensible, and cloud adaptable platform was successfully deployed in production, with OPX software at its core, and we’re looking forward to the future of the OpenSwitch project.”

    Vodafone Group Plc: Nicola Arnoldi, Lead Data Center SDN Network Architect
    “In Networking there are problems that need solving and solutions that need to be found to address those. We welcome disaggregation as liberation from the era of the ‘one-size-fits-all’ network operating systems. With open networking operating systems, engineers can finally cherry- pick the software protocol stacks and the hardware platform that make more sense to fulfill their business needs, and do that independently as long as the interfaces between HW and SW are standardized and widely recognized. We’re all very used to dealing with vendors whose innovation cycles are fairly slow due to the huge amount of features and combinations that need to be tested and validated every time. Eco-systems such as OPX allow to remove this feature clutter will unlock much faster and focused innovation that can be driven by the operators themselves, if that makes business sense for them. The control plane of a network is a constellation of apps that deserve to inherit the same design and architectural principles of software engineering, such as distribution, scaling, and high-availability. We think the approach that OPX has taken is solidly anchored to these principles, which may lead to a true, distributed, and easily operated network fabrics. We think that the open-source community has been a hugely powerful driver in almost all IT domains in the past 3 decades and OpenSwitch is yet another sign that disaggregated and composable networking is headed the right way.”

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).
