Three characteristics of the Internet of Things (IoT) differentiate it from industrial automation.
- IoT devices are inexpensive.
- IoT devices can be ubiquitously connected everyplace and anyplace.
- IoT devices have inexpensive or zero-cost deployment.
It explains why we see so few IoT networks and why most of the industrial IoT forecasts are measurements of industrial automation that we have had for decades.
The first one, with the exception of the issue of strong security, is easy. The second two, though, in New Jersey parlance — says easy does hard.
Ubiquitous connectivity is talked about, and there is a glimmer of hope presented by Low-Power Wide-Area Networks (LPWAN) such as Senet that focus on both low-cost technology and a business model for entrepreneurial partners to deploy networks. But waiting for carriers to perfect and deploy 5G networks to build IoT solutions will delay innovators and prevent early adopters from building proof-of-concept and prototype networks essential for the iterative learning of technical methods, business cases and making financial projections of the benefits of IoT.
I recently gave a webinar on how to best architect your network for Office 365. It comes on the heels of a number of complaints from customers around their struggles deploying responsive Office 365 implementations. SharePoint doesn’t quite work; Skype calls are unclear. And forget about OneDrive for Business. It’s incredibly slow.
Latency and Office 365
Ensuring a smooth transition to Office 365, or for that matter any cloud deployment, involves a solid understanding of which Office 365 applications are being deployed. Here latency matters. Microsoft recommends that round trip latency for Office 365 does not exceed 275 ms, but those metrics change significantly depending on the Office 365 application. Latency should not exceeds 50ms with Exchange Online and 25ms with SharePoint. (Check out my “ultimate” list of Office 365 networking tools for help with your O365 deployment.)
As a network engineer, an improperly configured application can cost a whole lot of time and money down the line. The best way to try and prevent these unfortunate accidents is by conducting thorough and efficient testing on a routine basis. Whether designing a network, migrating to the cloud, or adding a new device to the rack, every step within the application deployment life cycle should be validated with accurate testing.
Regarding network testing, the terms emulation and simulation are often used interchangeably. In most cases, either term will generally get the point across, but there’s a big difference between a network emulator and network simulator, both practically and semantically.
The Pervasive Network is far more than a collection of technologies and processes; it is a promise to be fulfilled. A promise of delivering constant, reliable, smart, secure, intelligent and scalable bandwidth to power a future of ubiquitous IoT devices, augmented reality experiences, super smart AI systems and innovation in the form of new mobile services and applications yet to be imagined. These technologies will be the building blocks for improving the operational efficiency of every business and providing customer experiences that will make the difference in every company’s competitive position going forward.
I have been on the customer and consultant side of the fence, and one thing has become clear to me: the network is not a commodity component, but a vital and strategic key to unlocking the potential of the innovation that we see in new services, experiences and opportunities.
Many years ago, when Arista Networks was in its infancy, its charismatic and sometimes controversial (at least to the folks at Cisco) CEO talked about how the company’s software-first approach would disrupt the networking industry. Just a few years later, the company stands a $1.7 billion revenue company with a dominant position in the webscale industry and a market cap of over $13 billion, so clearly CEO Jayshree Ullal’s prophecy came true.
Arista’s software rigor enabled the company to quickly jump into verticals where low latency and high performance mattered. Also, because of Arista’s software prowess, the company has been able to expand its addressable market to see to the networking needs of dense virtualization and containerized environments, as well as private cloud deployments, and quickly adapt the latest and greatest silicon.
Edge computing allows data produced by internet of things (IoT) devices to be processed closer to where it is created instead of sending it across long routes to data centers or clouds.
Doing this computing closer to the edge of the network lets organizations analyze important data in near real-time – a need of organizations across many industries, including manufacturing, health care, telecommunications and finance.
“In most scenarios, the presumption that everything will be in the cloud with a strong and stable fat pipe between the cloud and the edge device – that’s just not realistic,” says Helder Antunes, senior director of corporate strategic innovation at Cisco.
Lately, our clients with an MPLS WAN are starting to ask: “Should we get rid of our MPLS and go to SD-WAN? Is SD-WAN better?”
I don’t mean to make this question sound childish (since it’s a fantastically good question), but it reminds me of a mistake I made when my 9-year-old son asked me a question the other day.
He is obsessed with baseball, so, of course, he asked me something all of us baseball fans have wondered at some point: “Daddy, which is better… a guy who hits .250 with 50 home runs or a guy who hits .300 with 10 home runs?”
Combining power to operate equipment, as well as delivering substantial data rates that are good enough for video — in the same piece of radio kit — is now obtainable, scientists say.
The developing system works similar to how charging pads provide power to a toothbrush or a mobile phone without having to be connected through wires. However, in this case, the apparatus doesn’t need any physical contact with the device and data can be sent at the same time.
Magnetic fields are being used to transmit power through the air, North Carolina State University researchers say in a press release.
Like many IT products, SD-WAN products can sound insanely alike. Sit through presentations and read through the literature and then ask yourself what’s the practical difference between each vendor’s implementation? It can be difficult question to answer even for people in the business of answering those questions.
A common approach for an initial cut in an evaluation process is to reduce the product list by focusing on features. By creating a table of specific product specifications, assigning a weighted scoring, many of my customer have come up with a score and by extension a tool for eliminating some products from their selection process.
Such an approach while valuable in some respects, is insufficient even for an initial cut. There are too many elements to a purchase that are not measured by a features table. Or, there might be important unfamiliar features that you forget to include in the table.
Many organizations deploy new applications for their remote site users without testing it on a WAN. Not testing these applications across a simulated WAN increases the possibility of performance issues during the early stages of usage because you have no idea how the application will perform once latency or jitter come in between the communication path of the client and server.
If the application uses large amounts of bandwidth that causes congestion, then it can negatively affect the performance of other applications that share the bandwidth. A WAN emulator can enable you to measure the average bandwidth that an application may use before you deploy it.
In real estate, there’s a mantra that most agents use of “location, location, location,” meaning houses that may be equal in many ways will cost more the closer you get to something of value. For example, the San Jose Mercury News recently published a story about a house in Sunnyvale, California, that sold for $782,000 over asking price. Why such a ridiculous amount? Because it’s near Apple’s new campus — location matters.
Does location matter with the cloud? Given how fast data travels, one might not think so, but location does indeed matter. A recent report from EdgeConneX and Cedexis, Cloud, Content, Connectivity and the Evolving Internet Edge, shows just how much it actually does. The study conducted uses Cedexis’ RUM-based internet performance measurement tools to test how cloud applications perform in different locations and with various optimization techniques.
Every day we hear how the network is changing. Virtualization, Cloud, Software-defined Networking, the Internet of Things — it’s clear big transformational change is happening. The technical aspects of these solutions seem to get the most attention, but if you manage IT/Network cost and delivery for a living, your success may depend more on understanding the changing network business models that accompany these new technologies and how to adapt your IT operations.
I’ve assembled below what I think are five of the top operational challenges facing IT managers in the next generation network. Some of these are blocking and tackling fundamentals (excuse the seasonal American football analogy), while others are more strategic in nature. I’ll present a short rationale for why these are my top 5. I’d love to hear your perspective.
John Chambers, who served two decades as CEO of Cisco and for the last two years has been executive chairman, announced today that he will be leaving Cisco’s board of directors this year.
Cisco CEO Chuck Robbins will be appointed chairman of Cisco’s board of directors when Chambers vacates the position.
(Cisco CEO Chuck Robbins is seen on the left in the above photo with outgoing Executive Chairman John Chambers.)
“With Chuck Robbins as CEO and Chairman, the company is now clearly his,” says Zeus Kerravala of ZK Research, a Cisco watcher. “Robbins will have the ability to move the company in the direction he wants to.”
Aruba, a Hewlett Packard Enterprise Company, is best known for its outstanding business-grade Wi-Fi products. What’s less well known about Aruba is that it has always had excellent security products. In fact, I’ve often described the company as a security vendor dressed up as a Wi-Fi vendor, as Aruba and security have gone hand in hand like the New England Patriots and winning.
However, Aruba’s security positioning has always been tactical rather than strategic because its products were used for specific purposes, such as end point protection or wireless security. That shifted this week at APAC Atmosphere in Macau when the company introduced its 360 Security Fabric, which enables it to provide end-to-end security to address the needs of a world that is becoming increasingly digitized.
When discussing Ethernet data, the terms frame and packet are often used interchangeably. Frames and packets are the electronic containers that carry our data from point-to-point by navigating LANs and WANs and, as they both serve similar functions, their differences are often misunderstood.
So what’s the difference?
To simplify matters, imagine frames and packets as envelopes of information that are going to be sent from one person to another. The key difference between a frame and a packet is how they encapsulate the information and that depends on where the information is being sent.
Imagine a company with inter-department mail where a person can send documents to another person within their private/local organization. The contents are placed in an internal envelope and the sender writes their name and department in the “From” field, then writes the recipient’s name and department in the “To” field.

Scouring the online IT forums, it’s hard not to get sucked-in to all the talk about how MPLS is too expensive and can easily be replaced with high-bandwidth, fiber Internet circuits and an IPsec VPN. If you currently have an MPLS network, it almost makes you want to throw a blanket over it and hope nobody notices your “antiquated” Wide Area Network. [blushing]
The final straw was when you read how username Pauly-Packet-Loss just saved thousands by scrapping his company’s MPLS and it works great. [single tear rolls down your cheek]
It’s been about two months since Extreme Networks closed on the acquisition of Avaya Networking. As I pointed out, Extreme’s first partial quarter post close was a smashing success, which indicates the company is headed in the right direction. But now the real work begins.
In the two months since the close, the company has been extremely busy (pun intended) doing a bunch of things to integrate the companies, such as onboarding workers, bringing systems together and holding a unified sales conference. These things are obviously interesting and important, but the question on most customers’ minds is how long before there is integration at a product level?

Five years ago, IT was decentralized at the University of New Mexico. “Every school or college had their own IT, and in most cases they were completely under-resourced – a one-person shop having to do phones, apps, email, desktop, servers, storage, disaster recovery, all of that,” said Brian Pietrewicz, deputy CIO at University of New Mexico.
The university transitioned to a self-service model that enables each of its more than 100 departments to deploy infrastructure and application services itself and have them managed by the now-centralized IT team.
Adopting VMware’s vCloud Automation Center enabled departments to consume cloud resources, but also give the management team the ability to curtail that consumption if necessary.
