Each year, the Chapterthon project competition brings enthusiasm and excitement among our global community. We look forward to this time of year, when our communities mobilize and work alongside each other to achieve a common goal for the development of the Internet.
For the 2019 Chapterthon, we are delighted to announce that 34 Chapters and Special Interest Groups (SIGs) from across the globe have started implementing their work on local solutions that will bring some of the hardest-to-reach places and community segments online—connecting the unconnected.
Over the next two months, these 34 projects will:
Today's sponsored Tech Bytes explores how Big Switch Networks applies cloud design principles to data center and cloud networks. Network engineers can provide a developer-friendly environment while still enforcing policy, enabling security controls, and getting visibility into the network. Our guest is Big Switch CTO Paul Unbehagen.

It's a heaping helping of Network Break as we try to parse all the Kubernetes pronouncements coming out of VMworld 2019, including Project Pacific and Tanzu Mission Control. Plus we cover new tech and new partnerships between Dell EMC and VMware, new products from Apstra and Mellanox, and HPE's latest financials.

Have you ever seen a presentation in which a startup is telling you how awesome their product is because it allows you to simulate your whole network in a virtual environment? Not only that, you can use that capability to build a test suite and a full-blown CI/CD pipeline and test whether your network works every time you make a change to any one box in the network.
Sounds awesome, right? It’s also dead wrong. Let me explain why that’s the case.
Read more ...Last year when I was creating the first version of VMware NSX Deep Dive content, NSX-V was mainstream and NSX-T was the new kid on the block. A year later NSX-V is mostly sidelined, and all the development efforts are going into NSX-T. Time to adapt the webinar to new reality… taking the usual staged approach:
Summer has flown by and you may have missed some of the great content that was published. Don’t worry, you can catch up on some of our favorite podcasts, blog posts, and articles below. So settle in and then dive into all things open networking!
From Cumulus Networks:
Customizing your network: Take a quick look at the types of automation available in Linux, from basic to dynamic, and how these automation capabilities help to enable data center-wide orchestration here.
Kernel of Truth podcast: Network monitoring: When it comes to network monitoring, have you run into a “switch that cried wolf?”Kernel of Truth host Brian O’Sullivan is joined by two new guests to the podcast Justin Betz & Faye Ly to chat more about networking monitoring here.
Best practices: MLAG backup IP: We cover the best ways to build a redundant backup IP link for multi-chassis link aggregation (MLAG).
Exploring Batfish with Cumulus – part one: With Batfish supporting Cumulus Networks this year, we show how it can fit into pipelines & replace or complement existing testing strategies in part one of a two-part series.

ClearOS is an operating system based on CentOS for use in small and medium enterprises as a network gateway and network server with a web-based administration interface.
ClearOS in Gateway mode acts as a firewall, gateway and server on a local network. The tutorial provides installation and configuration steps for deployement of ClearOS on QEMU VM. We will later connect ClearOS QEMU VM into GNS3 network topology in order to test features such as application traffic filtering and transparent proxy with user authentication.
Software Used:
Host OS: Kubuntu Linux 18.04.1 LTS with Qemu 3.0.0 installed and kvm-intel module loaded
Guest OS: ClearOS 7.5.0 x86_64
1. Preparing Host Network Infrastructure
As we are going to install ClearOS guest QEMU VM in a gateway mode, your host should have two network adapters available. (Picture 1). In our case, the first ClearOS guest network interface ens3 will be defined as LAN type during ClearOS installation. The second guest interface ens4 will be defined as External and used for connection to SOHO network. We will bridge the interface ens4 with the host interface enp4s0f2 using iproute utility. But first, we need to create tap interfaces tap0 and Continue reading
Building a business case for SD-WAN involves more than just anticipating savings by moving from private circuits to business broadband connections. On today's Heavy Networking, we look at how to tie SD-WAN capabilities to business benefits, what to consider when developing a business case, how measure ROI, and more with guest Jason Gintert.
