IDG Contributor Network: Managing and securing the corporate WAN is the top challenge for network professionals

In December 2017, Versa Networks in tandem with Dimensional Research conducted a survey examining hundreds of participants across five continents with the primary goal of capturing how companies are managing and securing their network across branch locations. In addition, the research also investigated the expected benefits and challenges of a software-defined WAN (SD-WAN) and revealed trends when compared to a similar survey conducted in 2016.The survey found that network administrators face many hurdles when it comes to their organization’s WAN. Increasing costs due to the growing traffic volume over existing MPLS networks represented a major headache, followed by information security risks at the branch that could later erupt into a cyberattack or data breach.To read this article in full, please click here

Meet Me at VMware NSX Deep Dive Event in Zurich

When VMware launched the first version of NSX for vSphere more than four years ago, the NSBU team reached out to me and asked me to create a sponsored webinar describing NSX fundamentals, its architecture, and high-level deployment guidelines.

In the meantime we discussed updating the materials, but nothing ever happened. Time to fix that, this time from a vendor-neutral perspective. We’ll start with a day-long event on April 19th 2018 in Zurich, Switzerland.

IETF 101, Day 4: The Brass Tacks about DNS and Routing

This week is IETF 101 in London, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. And Thursday is probably the busiest day for us, covering the whole range of our interests.

ROLL has its first of two sessions starting at 09.30 GMT/UTC; continuing on Friday morning. There are several drafts being discussed dealing with the issues of routing over resource constrained networks where limited updates are possible.


NOTE: If you are unable to attend IETF 101 in person, there are multiple ways to participate remotely.


There’s a choice between a couple of working groups after lunch, starting at 13.30 GMT/UTC.

DOH was chartered to create a single RFC, so clearly the draft DNS queries over HTTPS is going to be the primary focus of discussion. However, there will also be updates on the practical implementation work, and a discussion about possible future work if there is a decision to re-charter the group.

6LO runs in parallel and has a fairly busy agenda with Registration Extensions for 6LoWPAN Neighbor Discovery, and Address Protected Neighbor Discovery for Low-power and Lossy Networks having received feedback from the IESG. Continue reading

Source of Truth

"Imagine walking down the park with your wife, and suddenly seeing your ex. Wife talks automation, she agrees. Wife says intent, she does the same. Wife talks container... and now they are best friends forever."

Since Cisco and Google announced a partnership to deliver a hybrid cloud solution last year, I started following back to see what my ex is doing in software space. During my time in Cisco it used to be a hardware-first company, or a "software solution that must run in own hardware"-first company, so it is interesting to hear about the announcement of Kubernetes-based Cisco Container Platform recently. It is great to see new materials from Cisco DevNet to transform the skills for Network Engineer towards software-based and automation, just like this awesome Network Programmability Basics video course.

One blog post by Hank Preston about "Network as Code" caught my attention. He laid the three principles of Network as Code: 
  • Store Network Configurations in Source Control
  • Source Control is the Single Source of Truth
  • Deploy Configurations with Programmatic APIs
and now I would like to expand more about this Source of Truth, in the context of network device config generation.

There’s still a lot of life left in tape backup

This industry likes to abandon technologies as soon as it adopts them, but a few find a way to hang around. I recently purchased a car, and in the finance office was a dot matrix printer, chugging away at the same multipage forms I saw used more than 25 years ago.Tape backup is also hanging in there. With data being produced in ever-increasing numbers, it has to be stored somewhere, and hard drives aren’t enough. For true mass backup, enterprises are still turning to tape backup, and the LTO Program Technology Provider Companies (TPCs) say 2017 shipments grew 12.9 percent over 2016 to 108,457 petabytes (PB) of tape capacity.Read also: The future of storage: Pure Storage CEO Charlie Giancarlo shares his predictions | Sign up: Receive daily network news updates LTO TPCs is a group consisting of three tape backup providers: HPE, IBM, and Quantum. There are other tape backup providers, such as Oracle, which inherited the StorageTek business from Sun Microsystems and still sells them, but it was not included in the count.To read this article in full, please click here
