  • Achieve actionable insight from the host to the switch
    Achieve actionable insight from the host to the switch
    Diane Patton, TME, Cumulus Networks and Scott Edwards, Director Product Marketing, Cumulus Networks Recorded: May 15 2018 56 mins
    As organizations grow and adapt to the digital age, networks must deliver richer application experiences to customers and connect more and more users. Agility is required in order to deliver compelling, brand-building, revenue-generating experiences. If there's ever a connection problem, the impact is significant and troubleshooting often requires manual, box-by-box intervention. There needs to be a better way.

    Luckily, Cumulus NetQ addresses these issues of network complexity and performance reliability. Cumulus NetQ reduces network operational headache by providing actionable insight into every trace and hop in the network — from the container, virtual machine, or host, all the way to the switch and port.

    Register for our webinar and learn more about Cumulus NetQ including:

    - Preventative validation which validates network behavior on a per-pod basis using check, show and trace algorithms
    - Proactive alerting which sends real-time alerts to users to notify of any network state deviation or packet loss
    - Full diagnostic troubleshooting which can trace network paths to replay the network at any point in time
  • Networking in the Container Age
    Networking in the Container Age
    JR Rivers, Cofounder and CTO of Cumulus Networks Recorded: Feb 13 2018 60 mins
    Container based applications are exploding in popularity as they simplify and speed up application development and deployment. Thankfully, technologies such as Docker, Kubernetes, and Mesos help to orchestrate and manage the containers. But with their dynamic nature, how do operations teams get their heads wrapped around inter container connectivity? How do they get full visibility across the entire fabric? How do they understand what was, or was not, working 10 minutes ago and why?

    In this webcast, you’ll learn about the popular container networking models and the pros and cons of each. You’ll also see how to track each container’s identity and bandwidth, how to simplify network port mapping, and realize the benefits of telemetry analysis through the entire fabric for enhanced troubleshooting.

    Orchestration tools for Linux containers can work in concert with Linux networking tools to help operationalize container based applications -- it’s just common sense. Come join us to find out how to make this a reality in your environment.

  • Architecting your Software: How Cloud & Containers Impact Data Center Networks
    Architecting your Software: How Cloud & Containers Impact Data Center Networks
    Andre Kindness, Forrester analyst and Brian O'Sullivan, Cumulus Networks Recorded: Sep 21 2017 47 mins
    Join Cumulus Networks and guest speaker Andre Kindness from Forrester as we explore the latest technology shifts in data centers today. As cloud, containers, microservices and other technologies become more and more mainstream, software must be architected in new ways to address these smaller components.

    All of this is impacting the the data center network, and we will talk through some of the ways that organizations can address the changes in the ever more complex data center. If you are an I&O professional, watch this webinar to see how you can simplify deployment and maintenance in the modern data center.
  • 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.

    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
    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
