IDG Contributor Network: Self-healing SD-WAN removes the drama of high-availability planning

My humble beginnings Back in the early 2000s, I was the sole network engineer at a startup. By morning, my role included managing four floors and 22 European locations packed with different vendors and servers between three companies. In the evenings, I administered the largest enterprise streaming networking in Europe with a group of highly skilled staff.Since we were an early startup, combined roles were the norm. I’m sure that most of you who joined as young engineers in such situations could understand how I felt back then. However, it was a good experience, so I battled through it. To keep my evening’s stress-free and without any IT calls, I had to design in as much high-availability (HA) as I possibly could. After all, all the interesting technological learning was in the second part of my day working with content delivery mechanisms and complex routing.To read this article in full, please click here

Using nmap on your home network

Nmap, the "network mapper" has long been used on corporate networks to collect information on desktop systems and servers. The tool provides information on the systems and services that are running (i.e., open ports). It can also help to identify rogue systems and vulnerabilities. Nmap makes it easy to detect changes as well as new systems on the network. Typical uses include: host discovery -- probing by IP address and providing information on the systems that respond port scanning -- identifying services that are available for use version detection -- identifying applications and their versions OS detection -- determining the operating system along with some hardware characteristics Sysadmins have been installing nmap on Linux for more than 20 years. Originally released in 1997, nmap has since that time become available for Windows and other Unix variants as well. In fact, it's considered a standard security tool and is a free and open source security scanner. It's typically used in corporate settings for collecting information on systems and doing security analysis.To read this article in full, please click here

Is the IoT in space about to take off?

Space may not be the final frontier for the Internet of Things, but evidence is mounting that it could be the technology’s next golden opportunity. While we’re still a ways away from the IoT in space becoming a commercially viable mainstream technology, a variety of companies are pushing the envelope in two significant ways.First, companies are working to realize the promise of satellite-powered networks that would bring the Internet of Things everywhere on earth. Second, vendors — and NASA — are exploring actual IoT applications and use cases beyond Earth’s atmosphere, in satellites and rockets.To read this article in full, please click here

BrandPost: How 802.11ax Improves the Experience for Everyone

The next advance in Wi-Fi, 802.11ax, is fast approaching. As we seek to raise the performance bar yet again for the sixth generation of Wi-Fi, the traditional techniques used in 802.11n and 802.11ac – wider RF channels, more MIMO antennas, higher QAM modulation – have been pushed almost to the limit, and it’s time to look for new ideas.802.11ax introduces techniques for ‘massive parallelism,’ especially OFDMA, multi-user MIMO, and ‘BSS coloring.’ All of these require the access point to make control decisions that have a significant effect on network performance, a new emphasis for Wi-Fi that will move access point networks closer to cellular base station infrastructure in terms of functionality.To read this article in full, please click here

BrandPost: Why is OFDMA a Magical Feature in the 802.11ax Standard?

As we explore the new features appearing in 802.11ax, the list is unbalanced. Some would say there’s a pig in the python. One feature – OFDMA – seems much more significant than the others. First, a brief background, then a view of its implications.A Quick Review of OFDMAOFDMA (Orthogonal Frequency Division Multiple Access) is an extension of the OFDM (Orthogonal Frequency Division Multiplexing) architecture. OFDM takes an RF channel, such as the 20 MHz channel often used in Wi-Fi, and instead of using a single carrier-frequency modulated by AM, FM, or other means, sets out a number of sub-carriers. 802.11ac used 52 data-carrying sub-carriers in a 20 MHz RF channel, while 802.11ax has 234.To read this article in full, please click here

IBM wants to manage your cloud services no matter which ones you run

ORLANDO – IBM has rolled out a multi-cloud management system that promises to help customers manage, move and integrate apps across multivendor cloud infrastructures.IBM’s new Kubernetes-based Multi-cloud Manager runs on the company’s year-old IBM Cloud Private platform but lets customers manage and integrate workloads on clouds from other providers such as Amazon, Red Hat and Microsoft.

What is a private cloud? [ And some things that it’s not]

Private cloud is a well-defined term that government standards groups and the commercial cloud industry have pretty much agreed upon, and while some think its use is waning, recent analysis indicates that spending on private cloud is still growing at a breakneck pace.A study by IDC projects that sales from private-cloud investment hit $4.6 billion in the second quarter of 2018 alone, which is a 28.2 percent increase from the same period in 2017.[ Also see How to plan a software-defined data-center network and Efficient container use requires data-center software networking.] So why are organizations attracted to private cloud?To read this article in full, please click here

How industrial predictive maintenance can prevent equipment failure

Entropy sucks. But industrial predictive maintenance can help it suck a little less for factories, oil rigs, aircraft engines, and even data centers. The key is to leverage the Internet of Things (IoT) and machine learning to help companies “accurately determine when a manufacturing plant, machine, component, or part is likely to fail, and thus needs to be replaced.”That, in a nutshell, is the point behind a fascinating new Google Cloud blog post by Prashant Dhingra, Machine Learning Lead, Advanced Solutions Lab, laying out “A strategy for implementing industrial predictive maintenance.”To read this article in full, please click here

Infrastructure life cycle costs: How ITAD and TPM can save you money

I was recently reading some responses to a question posted on the Spiceworks community forum that asked, “How do you dispose of old hard drives?" While there were some typically humorous responses, such as use them as target practice, smash them with a hammer, or drill a hole through them, I assume those comments were in jest. If not, those respondents are missing out on a great opportunity to get money back for their used equipment.It also reminds me of the need for safe, secure IT asset disposition (ITAD) services. It’s imperative to find an ITAD provider that offers data sanitization and destruction services that protect your company’s data integrity and privacy, handles your gear in an environmentally responsible way, and can also save your company money.To read this article in full, please click here

ICANN’s internet DNS security upgrade apparently goes off without a glitch

So far, so good. That’s the report from Internet Corporation for Assigned Names and Numbers (ICANN) as it rolled out the first-ever changing of the cryptographic key that helps protect the internet’s address book – the Domain Name System (DNS) on Oct. 11.The change is central to ICANN’s project to upgrade the top pair of cryptographic keys used in the Domain Name System Security Extensions (DNSSEC) protocol — commonly known as the root zone key signing key (KSK) — which secures the internet's foundational servers. This so-called root KSK rollover from the 2010 KSK to the 2017 KSK was supposed to take place almost a year ago but was delayed until Oct. 11 of this year because of concerns it might disrupt internet connectivity to significant numbers of web users.To read this article in full, please click here

BrandPost: Discover the Four Key Capabilities for Better IT Management

Management has always struggled how to optimize and oversee IT resources, tasks and operations. This challenge is becoming more complex due to “digital disruption”. As a result less tech-savvy companies are more likely to fall behind the competition and not able to attract top talent.Most of the times it is not that managers do not see the dangers of digital disruption coming. They do understand the challenges as well as the opportunities, and they know the competition sees them as well. Unfortunately, top management decisions often tend to focus on who is responsible for IT and where IT should be located, rather than the how.Generally, the assumption is that the right people will do the right work, either internally or in another company. However, this assumption is flawed. In that regard, an important reminder is that digital transformation is more about how companies do things, and less about who or where those tasks are performed. Digital disruption changes entire industries so fast that companies lack a structured process or the capabilities to handle it. IT management should offer not only the resources (people and equipment), but also the processes and capabilities to eliminate the risks, tackle the problems Continue reading

802.11: Wi-Fi speeds and standards explained

In the world of wireless, the term Wi-Fi is synonymous with wireless access in general, despite the fact that it is a specific trademark owned by the Wi-Fi Alliance, a group dedicated to certifying that Wi-Fi products meet the IEEE’s set of 802.11 wireless standards.These standards, with names such as 802.11b (pronounced “Eight-O-Two-Eleven-Bee”, ignore the “dot”) and 802.11ac, comprise a family of specifications that started in the 1990s and continues to grow today. The 802.11 standards codify improvements that boost wireless throughput and range as well as the use of new frequencies as they  become available. They also address new technologies that reduce power consumption.To read this article in full, please click here
