It’s certainly no secret that cloud solutions have become an important and increasingly necessary part of how companies do business today. For enterprises, implementing cloud-based services can help boost productivity, enhance efficiency and reduce costs. Private cloud solutions take ...
In Part V, we discussed processing delays caused by “slow” client and server nodes. In Part VI, we’ll discuss the Nagle algorithm, a behavior that can have a devastating impact on performance and, in many ways, appear to be a processing delay. Beyond being important for (reasonably) a...
When Swedish communications services provider TDC needed network infrastructure improvements from their disparate networks across several Nordic countries, they needed both simplicity in execution and agility in performance. Our next innovation case study interview therefore highlight...
We know that losing packets is not a good thing; retransmissions cause delays. We also know that TCP ensures reliable data delivery, masking the impact of packet loss. So why are some applications seemingly unaffected by the same packet loss rate that seems to cripple others? From a pe...
In Part II, we discussed performance constraints caused by both bandwidth and congestion. Purposely omitted was a discussion about packet loss – which is often an inevitable result of heavy network congestion. I’ll use this blog entry on TCP slow-start to introduce the Congestion Windo...
This is a summary of a QNX webinar that was just presented on July 10, 2014 by BlackBerry (BBRY) and QNX. This was an anticipated seminar because many people are looking for answers to questions they have about the big buzzword, the Internet of Things (IoT). They also want to know wha...

What do a firewall and a fortress have in common? They are no longer strong enough to protect the valuables housed inside. Like the walls of an old fortress, the cracks in the firewall are allowing the bad guys to slip in – unannounced and unnoticed. By the time these thieves get in, t...
Fundamentally, SDN is still mostly about network plumbing. While plumbing may be useful to tinker with, what you can do with your plumbing is far more intriguing. A rigid interpretation of SDN confines it to Layers 2 and 3, and that’s reasonable. But SDN opens opportunities for novel c...
As technology evolves, business models evolve. The corner grocery store gave way to the emporium, which became the supermarket. Now we order groceries online with a credit card, and a truck turns up with the goods. Hansom cabriolets became taxis and limos, and now we have Uber. At one ...
Just by its mere name, virtualization conjures up images of expensive, complicated technologies that for the most part only the largest companies can grasp, when in fact there are many benefits that virtualization can bring to small businesses, two being IT efficiency and cost savings....
Learn why network virtualization is the final frontier to conquer for high-utilization and high-performance clouds (since server and storage virtualization are already mature). 2013 was the year of SDN’s debut, but in his session at 14th Cloud Expo, Robert Drost, Co-Founder and COO o...
5G Networks are being discussed and better defined by key industry manufacturers and network carriers so they can be deployed in the 2020 time period. They will represent a giant leap in capacity, baseline speeds and overall capabilities. They have to. Consumers are turning to Smart...
If you're not virtualizing, you're missing reduced equipment, management, and utilities costs, along with increased server utilization rates and the right path to cloud computing. But when you virtualize, backup becomes even more of an issue. Traditional agent-based backup and recovery...
A recent post by John Wilmes on the TM Forum website caught my eye for drawing a parallel between the Uber car service business model and the telecom service provider business model as network functions virtualization (NFV) becomes a reality. Wilmes uses this metaphor to remind us of t...
American comedian Louis C.K. once observed on Late Night with Conan O’Brien that ”everything is amazing and nobody is happy.” And you know what? He’s right. He riffs about people complaining about the uncomfortable seats on a plane – despite the fact that they are partaking in the mi...
The proliferation of cloud-based applications for the enterprise grows each day, and more and more professionals have grown dependent on these apps as the consumerization of IT flourishes in today’s mobile enterprise. With the consumerization of IT, employees have become their own IT e...
