BrandPost: WAN Transformation – Security First or Network First?

It’s an exciting time in Wide Area Networking. With the rapid adoption of software-defined wide area networking (SD-WAN) architectures, we’re experiencing the biggest transformation in the WAN since the introduction of MPLS back in the late 90s.As with all new technologies, there is a lot of hype and a stampede of companies looking to capitalize on a hot new category. At last count, there were about 70 companies with marketing messages all vying to hop on the five letter “S-D-W-A-N” bandwagon.Interestingly, in the newly Gartner 2019 Magic Quadrant for WAN Edge Infrastructure, there are only two companies positioned as Leaders, Silver Peak and VMware. Seventeen others are positioned across the Niche, Visionary and Challenger quadrants. Ten additional companies are listed but didn’t meet the qualification criteria for inclusion in the Magic Quadrant.To read this article in full, please click here

There Is no Layer-2 in Public Cloud

The amount of layer-2 tricks we use to make enterprise networking work never ceases to amaze me - from shared IP addresses used by various clustering solutions (because it’s too hard to read the manuals and configure DNS) to shared MAC addresses used by first-hop router redundancy protocols (because it would be really hard to send a Gratuitous ARP message on failover) and all sorts of shenanigans we’re forced to engage in to enable running servers to be moved willy-nilly around the Earth.

Generating numeric sequences with the Linux seq command

One of the easiest ways to generate a list of numbers in Linux is to use the seq (sequence) command. In its simplest form, seq will take a single number and then list all the numbers from 1 to that number. For example:$ seq 5 1 2 3 4 5 Unless directed otherwise, seq always starts with 1. You can start a sequence with a different number by inserting it before the final number.$ seq 3 5 3 4 5 Specifying an increment You can also specify an increment. Say you want to list multiples of 3. Specify your starting point (first 3 in this example), increment (second 3) and end point (18).To read this article in full, please click here

Researchers aim for transistors that compute and store in one component

Researchers at Purdue University have made progress towards an elusive goal: building a transistor that can both process and store information. In the future, a single on-chip component could integrate the processing functions of transistors with the storage capabilities of ferroelectric RAM, potentially creating a process-memory combo that enables faster computing and is just atoms thick.The ability to cram more functions onto a chip, allowing for greater speed and power without increasing the footprint, is a core goal of electronics design. To get where they are today, engineers at Purdue had to overcome incompatibilities between transistors – the switching and amplification mechanisms used in almost all electronics – and ferroelectric RAM. Ferroelectric RAM is higher-performing memory technology; the material introduces non-volatility, which means it retains information when power is lost, unlike traditional dielectric-layer-constructed DRAM.To read this article in full, please click here

Wi-Fi 6 is slowly gathering steam

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.To read this article in full, please click here(Insider Story)

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.The crux of the matter is that, while access points with 802.11ax’s Wi-Fi 6 branding will steadily move into enterprise deployments in, the broader Wi-Fi ecosystem will not be dominated by the new standard for several years, according to Farpoint Group principal Craig Mathias.To read this article in full, please click here

A new spin on interconnects for colocation data centers

It has been almost a year since I first wrote about Stateless, Inc., a startup devoted to bringing software-defined interconnects (SD-IX) to colocation data centers. At that time, the company was just announcing its plans to reinvent the means to connect workloads across data centers, hyperscale clouds and on-premises footprints using SD-IX. The intent was to give colo service providers a simpler way to quickly deploy network services for their tenants. Those plans have come to fruition and the company has announced the general availability (GA) of its Luxon SD-IX platform.To read this article in full, please click here

Benefits of modern campus networking

Call it “trickle-down networking” if you like. But what has long been possible—and even best practice— in data center networking is now moving aggressively into and onto campus networking ecosystems. And with that move companies and organizations can realize numerous benefits in or on the campus networks they own or operate. As readers peruse this list of potential benisons, they’ll undoubtedly hit hot buttons with their users (thanks to increased features and functionality) and with management (thanks to cost savings and improved efficiencies that reduce staff time commitments and involvement).

Delivering key capabilities

With the adoption of data center tools and technologies in campus networks, a handful of key capabilities becomes available throughout. These include Power over Ethernet (PoE), which makes it possible to extend services more easily and affordably, and to integrate Internet of Things (IoT) capabilities more directly (such as sensors, surveillance cameras, ID badge readers and so forth). In addition, networks gain ready access to 802.1X capabilities when they adopt a data center model, including improved and more powerful authentication mechanisms, as well as access and security control.

Moving to data center-oriented networks usually also brings voice VLANs into the networking picture. This not only offers Continue reading
