Network World Networking
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.
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.
You know you need to protect your company from unauthorized or unwanted access. You need a network-security tool that examines the flow of packets in and out of the enterprise, governed by rules that decide whether that flow is safe, malicious or questionable and in need of inspection. You need a firewall.
When most non-technical people hear the term “seven layers”, they either think of the popular Super Bowl bean dip or they mistakenly think about the seven layers of Hell, courtesy of Dante’s Inferno (there are nine). For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.
The model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems (Is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”.
The selection process for our business-continuity-startup roundup began with dozens of recommendations and nominations sent via HARO, LinkedIn, Twitter, and subscribers to the Startup50 email newsletter.
This roundup, however, was challenging to flesh out because in the IT world, business continuity is a subset of storage.
Plenty of vendors pitched DevOps, security, and networking companie but none of those were a good fit for business continuity. You could make a case that all of those things help ensure business continuity, but they all fit better in different categories.
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.
So why are organizations attracted to private cloud?
ORLANDO — A mashup of technologies including artificial intelligence and automation will begin to make a significant impact on businesses and IT organizations in 2019 according to Gartner’s annual Top 10 Strategic Technology Trends report.
While computing, storage and programming have dramatically changed and become simpler and cheaper over the last 20 years, however, IP networking has not. IP networking is still stuck in the era of mid-1990s.
Realistically, when I look at ways to upgrade or improve a network, the approach falls into two separate buckets. One is the tactical move and the other is strategic. For example, when I look at IPv6, I see this as a tactical move. There aren’t many business value-adds.
In fact, there are opposites such as additional overheads and minimal internetworking QoS between IPv4 & v6 with zero application awareness and still a lack of security. Here, I do not intend to say that one should not upgrade to IPv6, it does give you more IP addresses (if you need them) and better multicast capabilities but it’s a tactical move.
Juniper is positioning the company to be an evangelist for network automation by announcing applications, tools, labs and libraries that it says will hasten adoption the technology for businesses and network professionals.
The inherent role of automation is to reduce the daily toil of repetitive tasks that lead to mistakes. It also provides guardrails to ensure service-level agreement guarantees. SLAs and reliability are not left to caffeine-powered individual heroics, but are achieved through well-trained automation heroes, also known as network reliability engineers (NRE), wrote Juniper's CTO and vice president, Bikash Koley, in a blog about the announcement.
If you are a career networking professional – be it a network architect, engineer, manager— do you need to advance your skillset to include programming and other DevOps skills to better serve you and your company?
With wireless now the preferred, default, and increasingly only access in the majority of in-building, campus, metro-scale hotspot and wide-area settings, achieving optimal performance is a key objective for IT departments.
Since radio-frequency (RF) propagation always involves a high degree of variability, it’s often difficult to predict the precise behavior of a given installation. Variables include operating conditions, user and application traffic demands, and the capabilities and settings of individual vendor products. When mobility, Wi-Fi testing and verification are also taken into consideration, performance evaluation can become very complex indeed.
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.
I know, I know, I’ve heard it before. A new technology comes along, and it promises to be the next big thing. Consumers and businesses buy it, and what happens? It fails to live up to the hype. In my opinion, almost every iPhone release over the past five years has been that way. Sure there were some cool new features, but overall it’s not something I’d say was game changing.
One technology that does promise to live up to the hype is 802.11ax, the next standard for wireless LANs. I say that because this next generation of Wi-Fi was engineered for the world we live in where everything is connected and there’s an assumption that upload and download traffic will be equivalent. Previous generations of Wi-Fi assumed more casual use and that there would be far more downloading of information than uploading.
Juniper CEO Rami Rahim is shepherding a number of key transitions for the company. Juniper made a big bet on 400G Ethernet this summer, detailing how it plans to transition its wide-area network, data center and enterprise portfolio to 400G Ethernet. And earlier this year, Juniper released its Contrail Enterprise Multicloud software, an SDN controller that is the central component of its multicloud, intent-based networking strategy.
If you weren’t in Amsterdam last week, you missed an extremely exciting conference – the Open Networking Summit Europe 2018. This Linux Foundation event drew more than 700 networking, development and operations leaders and enterprise users from open source service providers, cloud companies, and more.
Chief among the conference themes was the idea that open source networking is the "new norm," with lots of vendors attesting to how this theme is playing out in the IT industry. Dan Kohn who leads the Linux Foundation's Cloud Native Computing Foundation cites cost savings, improved resilience and higher development velocity for both bug fixes and the rolling out of new features for this change. Arpit Joshipura, General Manager of Networking at The Linux Foundation used the term "open-sourcification" in his keynote.
It was about 20 years ago when I plugged my first Ethernet cable into a switch. It was for our new chief executive officer. Little did she know that she was about to share her traffic with most others on the first floor. At that time being a network engineer, I had five floors to be looked after.
Having a few virtual LANs (VLANs) per floor was a common design practice in those traditional days. Essentially, a couple of broadcast domains per floor were deemed OK. With the VLAN-based approach, we used to give access to different people on the same subnet. Even though people worked at different levels but if in the same subnet, they were all treated the same.
Some Cisco Webex users are still having some problems with the collaboration system more than a week after the service went dark.
According to the company's website, a major outage began on September 25 and shut down all Webex services including Calling, Meetings, Control Hub, Hybrid Services and Team.
At the time, the company stated that “Webex Teams services are currently impacted by an ongoing service outage. Engineering resources are online and working to restore services. We apologize for the impact and all hands are on deck to restore Teams, Meetings, Calling, Care and Context services.”
In what could be a giant leap for Internet of Things (IoT) form factors, scientists say they have invented a spray-on antenna. And the bug-spray-like application will outperform traditional metal antennas, they claim.
If it indeed does outperform traditional antennas, the clear, ink-like radiators will transform physical mediums used in constructing networks. Flexible substrates, windows, or data center walls even could be made into antennas, which would then drastically alter the data-collecting landscape.
“Installing an antenna [could be] as easy as applying some bug spray,” an article on Drexel University’s website says.
