I am very excited about our next-generation R3 Series routing platforms, which are setting new standards for throughput, density, power efficiency and price performance. We designed these products to address the growing bandwidth demands in cloud datacenter and public networks, supported by significant Arista EOS enhancements including route scale, telemetry and security.

An attendee in my Building Next-Generation Data Center online course was asked to deploy numerous relatively small OpenStack cloud instances and wanted select the optimum virtual networking technology. Not surprisingly, every $vendor had just the right answer, including Arista:
We’re considering moving from hypervisor-based overlays to ToR-based overlays using Arista’s CVX for approximately 2000 VLANs.
As I explained in Overlay Virtual Networking, Networking in Private and Public Clouds and Designing Private Cloud Infrastructure (plus several presentations) you have three options to implement virtual networking in private clouds:

Today we welcome sponsor SnapRoute for a Tech Bytes conversation. SnapRoute makes CN-NOS, a network OS that runs on whitebox hardware. We discuss the NOS's containerized design that lets you update, test, and replace components; its use of Kubernetes to tie into automation pipelines; and customer use cases.

In Systemantics: How Systems Really Work and How They Fail, John Gall says:
A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system.
In the software development world, this is called Gall’s Law (even though Gall himself never calls it a law) and is applied to organizations and software systems. How does this apply to network design and engineering? The best place to begin in answering this question is to understand what, precisely, Gall is arguing for; there is more here than what is visible on the surface.
What does a simple system mean? It is, first of all, an argument for underspecification. This runs counter to the way we instinctively want to design systems. We want to begin by discovering all the requirements (problems to be solved and constraints), and then move into an orderly discussion of all the possible solutions and sets of solutions, and then into an orderly discussion of an overall architecture, then into a nice UML chart showing all the interaction Continue reading

Antidote is a network emulator combined with a presentation framework designed to create and deliver networking technology training. Its user interface operates in a web browser, including the terminals that students use to run commands on emulated network devices and servers.
Antidote is the engine that runs the Network Reliability Labs web site. Antidote is an open-source project, released under the Apache license. A standalone version of Antidote may be installed and run on your personal computer using the selfmedicate script. In this post, I will install Antidote on my Linux laptop and make a few changes that improve Antidote performance on my Linux system.
The Antidote documentation is being expanded regularly but, at the time I am writing this, the most helpful information is in the NRE Labs blog and in the videos produced by the developers. Most of these are accessible from the NRE Labs Community Resources page.
Also, Antidote is in active development and it is changing quickly as the developers create new features and content. Keep that in mind when following this blog post. Some things may already have changed about the way Antidote installs or operates.
Antidote requires that you Continue reading
Today's Network Break explores why Microsoft is adding a Linux kernel to Windows, examines a new SD-WAN colo option from Cisco, discusses a new offering from VMware and Dell EMC that lets you get infrastructure on premises but pay for it like the cloud, plus more tech news and a couple of follow-ups.

Dead end: ProPublica has a story about Kentucky’s $1.5 billion broadband expansion program, which the story calls an information highway to nowhere. The program is behind schedule and over budget, with the state’s IT chief directing money to other projects and partnering with commercial ISPs.
Broadband billions: Meanwhile, the U.S. Department of Agriculture says that bringing broadband to unserved areas of the country would generate $47 billion of new economic activity a year, according to a story at Talkbusiness.net. Broadband in rural areas would enable precision agriculture technologies, which allows high-tech crop management based on sensors and other connected data sources.
I can’t Google: Finally, our broadband access trifecta of stories concludes with a Cronkite News story about the lack of access in many U.S. tribal areas. “Just Google it” has become a bit of a joke among the Hopi tribe in Arizona because many areas don’t have Internet access.
The luxury of privacy: Consumer privacy online can’t be a luxury good that only the rich have access to, Google CEO Sundar Pichai said recently in an opinion piece at the New York Times. Speaking at a conference, Pichai also spoke in favor of privacy legislation Continue reading
