Hedgehog – The Network OS Distro?

You’ve probably seen by now that there’s a new entrant into the market for network operating systems. Hedgehog came out of stealth mode this week to fanfare from the networking community. If you read through the website you might question why I labeled them as a network operating system. While they aren’t technically the OS I think it’s more important to look at them as an OS distribution.

Cacophony of Choice

Hedgehog starts from a very simple premise. Cloud networking is where we’re all headed. Whether or not you’re running entirely on-premises, fully in the public cloud, or in some kind of super-multi-hybrid cloud offering you’re all chasing the same thing. You want a stable system that acts as a force multiplier for your operations teams to reduce deployment times for users to get their builds done. It’s been said before but the idea of cloud is to get IT out of the way of the business.

Streamlining processes means automating a lot of the things that were formerly done by people. That means building repeatable and consistent tools to make that happen. If anyone has ever worked on AWS or Google Cloud you have lots of access to that Continue reading

🎬 EVPN-VXLAN Explainer - now on youtube.
📔 An update on what I've been up to, lots of EVPN.
🦀 MY other project - learning Rust

EVPN-VXLAN Explainer 1

My recent EVPN Explainer posts were essentially preparation for a video series, covering roughly the same content.
With the large amount of detail required, and as I refined my messaging, I felt that a blog was a better medium to use at first. Videos are much harder to edit and correct any mistakes. Thus I wanted to try out my content in writing, then move on to creating the videos.

After a couple of weeks preparing and recording, along with my main job, I'm happy to say that I've released the first video, and here it is:

This video is a gentle introduction to EVPN, focusing on the high-level operation and configuration, rather than going to deep. With the basics out of the way, I'll be going into the details, much like my blog posts, in later videos.

A Brief Update AKA What I've been up to

As the long, hot summer of 2022 draws to a close, I've put away the flip-flops and dived straight back Continue reading

Getting Ahead Of The Game: Inspur’s Machine For Digital Twins And Immersive Experiences

Commissioned: Not everybody wants to be Iron Man. But there isn’t an artist or engineer around that doesn’t envy the 3D, immersive design experience that Tony Stark used to invent new equipment and analyze his existing gadgets in the Avenger movies. …

Video: Bridging Beyond Spanning Tree

In this week’s update of the Data Center Infrastructure for Networking Engineers webinar, we talked about VLANs, VRFs, and modern data center fabrics.

Those videos are available with Standard or Expert ipSpace.net Subscription; if you’re still sitting on the fence, you might want to watch the how networks really work version of the same topic that’s available with Free Subscription – it describes the principles-of-operation of bridging fabrics that don’t use STP (TRILL, SPBM, VXLAN, EVPN)

EVPN VLAN-Aware Bundle Service

In the EVPN/MPLS Bridging Forwarding Model blog post I mentioned numerous services defined in RFC 7432. That blog post focused on VLAN-Based Service Interface that mirrors the Carrier Ethernet VLAN mode.

RFC 7432 defines two other VLAN services that can be used to implement Carrier Ethernet services:

  • Port-based service – whatever is received on the ingress port is sent to the egress port(s)
  • VLAN bundle service – multiple VLANs sharing the same bridging table, effectively emulating single outer VLAN in Q-in-Q bridging.

And then there’s the VLAN-Aware Bundle Service, where a bunch of VLANs share the same MPLS pseudowires while having separate bridging tables.

Google launches VMs powered by newest Intel Xeon

Google Cloud announced new virtual machines as part of its cloud platform based on Intel’s newest Xeon Scalable processors.In addition to the new C3 virtual machine series, Google also announced it is deploying Infrastructure Processing Units (IPU), which are designed to intelligently route network traffic and take the load of network data processing off the CPU. The  company made the announcements at its Google Cloud Next ’22 conference held virtually.The IPU chip, formally known as the E2000, was co-designed by Google and Intel together and features 16 Arm Neoverse cores and 200GbE networking.C3 machine instances deliver performance gains of up to 20% over previous generation of C2 instances. They also benefit from a recent product launch called Hyperdisk, a block storage system that offers 80% higher IOPS per vCPU for data analytics and DBMS workloads when compared to other hyperscalers,To read this article in full, please click here

Hedge 150: Micah Beck and Universal Broadband

What would the Internet look like—or what kinds of services would need to be developed and deployed—to make boradband class service available to every user? What could this kind of development do to drive entire societies forward? Micah Beck, from the University of Tennessee, joins Tom Ammon and Russ White to discuss universal broadband on this episode of the Hedge.
