Reaction: Some Sayings that Sum Up Networking
Over at the CIMI blog, Tom Nolle has a mixed bag of sayings and thoughts about the computer networking world, in particular how it relates to the media. Some of these were interesting enough that they seemed worth highlighting and writing a bit more on.
“News” means “novelty”, not “truth”. In much of the computer networking world, news is what sells products, rather than business need. In turn, Novelty is what drives the news. The “straight line” connection, then is from novelty to news to product, and product manufacturers know this. This is not just a vendor driven problem, however; this is also driven by recruitment, and padding resumes, and many other facets of the networking nerd culture.
On the other hand, novelty is never a good starting place for network design. Rather, network design needs to start with problems that need to be solved, proceeds by considering how those problems can be solved with technologies, then builds requirements based on the problems and technologies, and finally considers which products can be used to implement all of this at the lowest long term cost. This is not to say novelty is not useful, or is not justified, but rather that Continue reading
Off the Cuff – Site Reliability Engineering
Site Reliability Engineering is a concept that the networking world is coming to terms with. At Interop ITX 2018, Network Collective took the opportunity to sit down with Michael Kehoe to get his take on how SRE concepts can improve network operations.

Networking’s Future, Not Networking’s Past
VMware Continues as a Visionary in 2018 Gartner Data Center Networking Magic Quadrant
We are excited to announce that for the fifth year in a row, VMware has achieved the position of visionary in the Gartner Magic Quadrant for Data Center Networking, which is defined as…understanding where the data center market is going and having a vision for changing market rules.
Five Years! That’s a long time in technology! During that time, we’ve all seen the rise of public cloud providers and massive shifts in cloud constructs and cloud management platforms. Application development trends have gone from monolith to virtual machines to containers and micro-services to serverless functions and events. Application components are getting smaller, datacenter edges are disappearing, management platforms are becoming more flexible and the basic requirements of networking and security have remained the same…connect and protect applications and data. Only applications and data are now constantly changing with agile development practices and multi-cloud strategies…and the VMware networking portfolio is evolving to make sure they stay connected and protected!
For evidence, look at our recently announced vision for the Virtual Cloud Network.
The foundation of that vision for a networking industry transition to software was started by VMware with virtual switching, expanded into the data center with the groundbreaking VMware NSX network virtualization platform, and is now powering software-based networks from data center to cloud to branch to edge for our enterprise and service provider customers. We’ve led this transition by defining network virtualization; by creating an entire industry movement around micro-segmentation; and by continually evolving NSX capabilities to provide advanced Continue reading
Last Month In Internet Intelligence: June 2018
In June, we launched the Internet Intelligence microsite (home of this blog), featuring the new Internet Intelligence Map. As the associated blog post noted, “This free site will help to democratize Internet analysis by exposing some of our internal capabilities to the general public in a single tool. …. And since major Internet outages (whether intentional or accidental) will be with us for the foreseeable future, we believe offering a self-serve capability for some of the insights we produce is a great way to move towards a healthier and more accountable Internet.”
While we will continue to share information about Internet disruptions and events as they occur via @InternetIntel, we also plan to provide a monthly roundup in a blog post, allowing readers to learn about Internet disruptions and events that they may have missed, while enabling us to provide additional context and insight beyond what fits within Twitter’s character limit.
Exams
In the past, countries including Iraq, Syria, and Ethiopia have implemented partial or complete national Internet shutdowns in an effort to prevent student cheating on exams. This past month saw Iraq implement yet another round of Internet shutdowns, and Algeria began Continue reading

Review: Ansible for Networking Engineers
An engineer attending Ansible for Networking Engineers online course sent me this feedback:
This is a great place to learn Ansible and Network Automation from scratch. Starting with an emphasis on the fundamentals (YAML, JSON, Jinja2, how to group your network devices for automation, etc.) you progressively build up towards useful network automation.
He particularly liked the additional features that are part of any ipSpace.net online course:

Snowflake Networks
Snowflake networks, sounds like a good name for a network design company, but this is not what this post is about. Are you familiar with the concept of a snowflake network? This terminology comes from the notion that each snowflake is unique at a molecular level. In networking, many networks don’t look the same, so the term snowflake networks was coined.
Lately there’s been a lot of discussions on networks being snowflakes. Especially on some of the podcasts (you know which ones). What is being discussed is that we need to move away from designing networks that are complex, networks that are snowflakes. Every network is 95% the same and only the last 5% is unique. First, let me agree that snowflakes are bad. Personally I believe we should adhere to the following design tenets if possible:
Don’t use more complexity than needed
Use as much L3 as possible
No stretching of L2
Don’t use more protocols than needed
Don’t change default setting unless needed
Don’t “gold plate” the design
Don’t use “nerd knobs”
I think most of us, if not all, can agree that these tenets make sense when designing a network. So why do networks end up being Continue reading
Network Notes: Ethernet
The original ethernet specification was owned by DEC, Intel and Xerox hence the standard being named "Ethernet (DIX)". The ethernet specification has been through a number of updates over the years beginning with the IEEE standard in the early 1980's and going through many revisions....continue reading
