  • The Blurring of Boundaries in a Software-Defined Data Center
    The Blurring of Boundaries in a Software-Defined Data Center JR Rivers, Co-Founder & CTO, Cumulus Networks Recorded: Aug 17 2017 34 mins
    The software-defined data center has been a heavily touted concept over the past few years, and heralded by some as the next step in the evolution of virtualization and cloud computing. Having a data center that is governed by software, rather than dictated by hardware, can lead to more fully automated and intelligent operations. Having infrastructure elements such as networking, storage and security conceived of as a services is, indeed, an attractive concept to many.

    In this webinar we will be joined by JR Rivers, Co-Founder and CTO of Cumulus Networks, to talk about how he (and Cumulus) define the concept of a software-defined data center. He will present how the definition of a software-defined data center has evolved since its inception, and how tools like VXLAN, EVPN, Ansible and more can help organizations further their journey to a “software-defined” state and simplify network operations.
  • Packet Buffers: Best Practices for A Buff Network
    Packet Buffers: Best Practices for A Buff Network JR Rivers, Cumulus Networks Co-founder and CTO Recorded: May 14 2017 75 mins
    Packet buffer memory is among the oldest topics in networking, and yet it never seems to fade in popularity. Starting from the days of buffers sized by the bandwidth delay product to what is now called "buffer bloat", from the days of 10Mbps to 100Gbps, the discussion around how deep should the buffers be never ceases to evoke opinionated responses.

    In this webinar we are joined by JR Rivers, co-founder and CTO of Cumulus Networks, who has designed many ultra-successful switching chips, switch products, and compute platforms, to discuss the innards of buffering. This webinar will cover data path theory, tools to evaluate network data path behavior, and the configuration variations that affect application visible outcomes.
  • Network Automation: A deep dive on how to manage an automated network
    Network Automation: A deep dive on how to manage an automated network Dinesh Dutt, Cumulus Networks Chief Scientist Recorded: Apr 12 2017 55 mins
    In episode 2 of our series on automating network configuration, we will dive deeper into the how-to's for managing an automated network in production. We'll walk you through the model of CI/CD (Continuous Integration / Continuous Delivery), including deploying changes with more confidence than you could before. We'll show you how Cumulus Linux simplifies much of automation thanks to simplifications and innovations in configuration from CLAG to Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP). Come prepared for a lively webinar with real-time demos and active audience participation.
  • Network Automation: Tools, Challenges and Solutions
    Network Automation: Tools, Challenges and Solutions Dinesh Dutt, Cumulus Networks Chief Scientist Recorded: Apr 12 2017 88 mins
    Network automation may seem passe now; seemingly everyone knows how to do it. You want to join the ranks, but where to begin? And what does the journey look like? In this 2 part webinar, we'll go from soup to nuts on automation of network configuration, from downloading Ansible to doing continuous integration and continuous development with network operations. Along the way, we'll demonstrate how Cumulus Linux simplifies much of automation thanks to simplifications and innovations in configuration from CLAG (Chassis Link Aggregation) to OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol).

    Even if you think you know BGP unnumbered, come see how we've simplified it even further. We'll walk through configuring L2 networks, L3 networks, and VxLAN overlays.
  • Network Command Line Utility: A command line to improve network automation
    Network Command Line Utility: A command line to improve network automation Dinesh Dutt, Cumulus Networks Chief Scientist Recorded: Apr 1 2017 79 mins
    Automation. Everyone wants it, even if not every one can readily switch to it. Manual workflows are still quite common in today's networks and while Linux supports manual workflows, some traditional network operators find administering networks with the standard Linux network commands challenging.

    With NCLU, Cumulus Linux makes manual workflows first class citizens in the network operator toolchain. Designed to please both Linux admins and traditional network operators, the primary goal of NCLU is to ease and simply the manual operation of networks.

    Watch this webinar and learn:
    - Why command line still matters, and what the characteristics of a good CLI look like
    - How to simplify Linux network administration with NCLU
    - How traditional network operators can start to reap the benefits of Linux networking
    - Some everyday examples of network administration using NCLU
  • Facebook Backpack: An open chassis for modern network operators
    Facebook Backpack: An open chassis for modern network operators JR Rivers, Co-founder and CTO of Cumulus Networks Recorded: Feb 24 2017 71 mins
    In February 2017, Facebook announced the first commercially available open networking chassis. Traditionally sourced through traditional vendors where all components must be sourced from a single provider, the open chassis is the next step in web-scale networking for the masses.

    Join this webinar to get an overview of the technical architecture of the backpack and learn how the availability of this new model, is making it simple for data center operators to take advantage of the first open ecosystem chassis.

    Plug into to learn how you can take the web-scale IT principles of innovators like Facebook, Google, and others to your organization simply and cost-effectively.
