What is the open packet optical switch, Voyager?
Modern web-scale data centers are thirsty for bandwidth. Popular applications such as video and virtual reality are increasing in demand, causing data centers to require higher and higher bandwidths — both within data centers and between data centers. In this blog post, we will briefly discuss the current challenges in the optics space as well as some of the key technical aspects of the Voyager’s DWDM transponder. In part two of this series, we will cover why Voyager is a unique, powerful and robust solution.
The challenges to accommodate longer distances
Within a data center, organizations are adding higher and higher bandwidth ports and connections to accommodate the need for more bandwidth. However, connections that accommodate longer distances between data centers may be limited and expensive. Therefore, a critical requirement for businesses with this challenge is how to support longer distance spans at higher bandwidths over a small amount of fiber pairs.
The optical industry solves the bandwidth problem using Dense Wave Division Multiplexing (DWDM). DWDM allows many separate connections on one fiber pair by sending them over different wavelengths. Although the wavelengths are sent on the same physical fiber, they act as “ships in the night” and don’t interact Continue reading
Community Networks in Mexico: For Ourselves, With Our Own Resources
Community Networks are a matter of autonomy, which has been demonstrated by the indigenous communities of Mexico and the world. Like languages, the traditional crop-growing system milpa, the communal land, assembly, and tequio – or community work – it is a tool that addresses the needs of humanity.
Radio, telephony, and community wireless Internet and Intranet networks (local content offline platforms) acquired and operated by the communities themselves, not only respond to the human right to communication and connectivity, but also to the right to exercise it from their own values and principles; to the possibility of discussing and deciding, for example, how it will work, where the infrastructure will be placed, who will be responsible for the maintenance, when it will be used, and how the network that belongs to everyone will be sustained.
The Mexican Constitution recognizes in its Article 2 the system of traditional organization of indigenous communities and the right to establish their own means of communication, in addition to requiring authorities to create the conditions so that they can operate and administer them in accordance with the law. Although the conditions are written on paper, there are persistent legal and bureaucratic obstacles that distance Continue reading
Episode 24 – Building Resilient Networks
The need for resiliency in network infrastructure is almost a given, but how do you get there? John Herbert, Jody Lemoine and Pete Welcher join the Network Collective team to talk through the complexities involved in a highly available infrastructure.
We would like to thank Cumulus Networks for sponsoring this episode of Network Collective. Cumulus is offering you, our listeners, a completely free O’Reilly ebook on the topic of BGP in the data center. You can get your copy of this excellent technical resource here: http://cumulusnetworks.com/networkcollectivebgp

Forget Facebook and Intel, Is Anyone Else Using OCP Data Center Gear?
Open Compute Project market impact surpassed $1 billion last year, according to new data from IHS Markit. But it’s still only about 1 percent of the overall market value, which IHS Markit says reached $137 billion in 2017.

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.

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
Source of Truth is the Continue reading
