Africa Needs Its Internet Institutions More Than Ever, Especially AFRINIC

At the recent African IGF in Khartoum, on November 5, participants of the workshop on “Strengthening the Institutional Capacity of Critical African Internet Institutions” hailed the achievements of African Internet institutions in bringing connectivity and broadening access in the last decades. They also recognized their shortcomings and stressed the need to address them so that they continue to serve the continent amidst the potential challenges that it will be facing in the future, as the African Internet grows and more users come online. The workshop was organized by AFTLD, the African Union Commission, and the Internet Society.

Fifteen years ago, Africa had less than 3% Internet penetration and was trailing far behind the rest of the world. Today, with a third of its population connected to the Internet, Africa’s connectedness is still behind but in a much better position than before, since the gap in Africa and the rest of the world has been shrinking. In fact, some countries in Africa have connectivity levels comparable to those of developed countries – something unimaginable fifteen years ago!

The progressive increase in Internet penetration in Africa could not happen without its regional Internet organizations, known as Af*, and the various NOGs (Network Continue reading

Why did Oracle acquire an SDN firm?

Every now and then, the industry gets hit with a “huh?” acquisition, like Facebook buying virtual reality headset maker Oculus or chipmaker Broadcom acquiring mainframe software vendor CA.Last week’s news from Oracle was also up there, with the announcement it plans to acquire Talari Networks, a software-defined networking (SDN) specialist, by the end of the year.It would seem an odd pairing, but Oracle has a considerable communications software business of mostly brokers, controllers, and monitors. In announcing the deal, the company said Talari would complement Oracle’s Session Border Controller (SBC) and network management infrastructure by adding high availability, Quality-of-Experience (QoE) connectivity, and cloud application access across any IP network with the reliability and predictability of private networks.To read this article in full, please click here

Why disk beat tape in the backup wars

Any backup experts worth their salt switched to disk as the primary target for backups many years ago. Tape still reigns in long-term archival, for the reasons laid out here. But tape is also quite problematic when it comes to day-to-day operational backup and recovery.To read this article in full, please click here(Insider Story)

Using VXLAN and EVPN to Build Active-Active Data Centers

Some (anti)patterns of network industry are way too predictable: every time there’s a new technology marketers start promoting it as the solution for every problem ever imagined. VXLAN was quickly touted as the solution for long-distance vMotion, and now everyone is telling you how to use VXLAN with EVPN to stretch VLANs across multiple data centers.

Does that make sense? It might… based on your requirements and features available on the devices you use to implement the VXLAN/EVPN fabric. We’ll cover the details in a day-long workshop in Zurich (Switzerland) on December 5^th. There are still a few places left, register here.

My time as an intern (thus far)

It has been over three months since I started as a marketing intern at Cloudflare. Even before joining the Cloudflare team, I enjoyed reading the technical blog posts about Cloudflare’s use cases and solutions, as well as the inclusive and creative culture. Educating the world about the threats we face on the Internet is something that I found truly valuable. I figured that I would give my own spin on what it’s like to join and work at Cloudflare by writing a blog post too.

Chapter 1: The Path towards the Orange Cloud

Before starting as a freshman in university, I created an online portfolio for my photography. It has been a passion of mine for about 9 years. I tried a multitude of platforms but none afforded me the aesthetic control that I wanted. The only solution was to build and host my own site. I started learning HTML/CSS, a bit of JavaScript and jQuery and so on.

This led to me using the Koken CMS, and hosting it on DigitalOcean in a Docker container. What was left was SSL/TLS encryption and a CDN (my friends in Europe find the loading times unbearable). Continue reading

Cumulus Networks Open-Ended NCLU Net Example Command

NCLU is the always helpful Network Command Line Utility. It’s a command interface for our products and platforms that’s designed to provide direct, simple access to network configuration information. Thus, NCLU supports both inspection and modification of Cumulus Networks configuration data. Better yet, NCLU is easy to customize for local environments and naming conventions using its net example facility.

NCLU Overview

In general, NCLU enables users at the command line to learn about current configurations, and make changes or additions to such configurations. NCLU reports on Interfaces and can provide information about IP addresses, VLANs, Access controls, Trunking, STP, and more. At the routing level, NCLU provides information about Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF) routing protocol settings and configurations. NCLU also offers information about services, including hostnames, NTP (Network Time Protocol), Timezone, and so on.

NCLU also includes comprehensive, context-sensitive help. Starting with the basic net command, users can learn about the various sub-commands available to them. Similarly, entering net <sub-command-name> provides help for that specific sub-command. This is how Cumulus (and other forms of) Linux delivers help information for users of complex commands like net.

In addition, NCLU commands provide control over configuration staging, Continue reading

BrandPost: SD-WAN: Optimizing User Experience for Managed Cloud-hosted Applications

Digital Transformation touches the network Applications are moving to the cloud – a lot of them. IDC estimates that by 2020, 90% of enterprises will use multi-cloud, i.e. multiple pub­lic and private cloud services and platforms, to support their ever-expanding application requirements. Service providers have a unique opportunity to leverage a high-performance managed SD-WAN solution to deliver the best possible cloud connectivity and therefore the best “quality of experience” to enterprise users.A new breed of applications with different needs Applications require a different quality of experience based on business priority, geography and security considerations, and consequently, they must be handled accordingly across the WAN. Some trusted business applications like Office 365, Skype and SAP can be sent directly to the internet with confidence, while recreational applications such as Facebook and Twitter might require higher security controls in order to meet enterprise security and/or compliance requirements. Simply put, the SD-WAN internet connectivity option must include the ability to differentiate traffic based on each application to ultimately enforce granular security policies.To read this article in full, please click here

Cumulus Linux Automation with Standard Linux Tooling

One thing’s for sure: The world of networking and networking administration is quickly changing. Part of this change is an evolution from old-school, proprietary centralized networking to more open options. This evolution has several different effects on the way network designers, administrators and engineers design and operate the network. This blog will focus on the different options available for modern automation, and how the Cumulus Linux approach provides the greatest amount of flexibility.

Breaking the Stranglehold

It wasn’t too long ago that the few big networking vendors had an almost unbreakable grip on organizational networking implementations, and correspondingly, with the way these implementations were managed. For most, this included the configuration of the various types of networking equipment using a command-line interface (CLI) and proprietary commands. Automating these types of solutions most often required either an offering developed by the vendors themselves, or the use of an application programming interface (API) written to interface with their products.

The question is whether this was a good thing or not. Generally, vendor-specific solutions have their advantages because they’re able to interface closely with the specific device code and take advantage of communications between the device coding team and the tools coding team.

Chip-cooling breakthrough will reduce data-center power costs

Traditional passive heatsinks affixed to microprocessors for cooling don’t work well enough for today’s high-speed computations and data throughputs and should be junked, says a group of mechanical engineering researchers.A better option, they say, are "spirals or mazes that coolant can travel through" within tiny channels on the actual processor. That technique could massively improve efficiency, says Scott Schiffres, an assistant professor at Binghamton University in New York, in an article on the school's website. The school has developed this new method for cooling chips.To read this article in full, please click here

On the ‘net: Network Operating Systems

For those with a long memory—no, even longer than that—there were once things called Network Operating Systems (NOS’s). These were not the kinds of NOS’s we have today, like Cisco IOS Software, or Arista EOS, or even SONiC. Rather, these were designed for servers. The most common example was Novell’s Netware. These operating systems were the “bread and butter” of the networking world for many years. @ECI
