Slow and Steady Doesn’t Win This Digital Business Race

Image for BlogWhen I talk to network professionals, I routinely ask them about the one part of their job that keeps them up at night. The thing that consistently comes up is their network speed required for delivering a consistent reliable user experience: or specifically, the lack of it. They usually follow up this admission by saying that their network is not always slow, but the rate at which the business introduces new applications and new ways of leveraging technologies is definitely trending towards the network not being able to keep pace.

I know exactly what they’re talking about. Unfortunately, with the way things are trending, going with the idea of, “It has always worked, why change it?” is becoming less of a viable solution.

In the coming years, thanks to the accelerated pace of BYOD/CYOD and IoT adoption, this trend will be extremely important for IT to address. In fact, according to the Virtual Mobile Networking Index, wireless traffic will increase ten-fold by 2019. Not only will more devices be connecting to the network, but also they will access a lot more business critical applications requiring performance, reliability, and user experience than ever before.

Sorry network pros, but your legacy network’s performance and reliability are going to be scrutinized more than ever. Read More »

Making sense of Service Provider Virtualization

nehib-1Guest blog by Greg Nehib, SP Product and Solutions Marketing

I like to think of virtualization as an expanded networking toolkit, providing us with additional options to get the job done. It’s almost like when cordless tools entered the consumer tool market. You could take the cordless tools anywhere and use them in new and exciting applications. But there was a key drawback that I’m sure you remember. The early cordless tools had a limited effective power range. Over the next decade or two, battery technology improved and there were fewer power related drawbacks to going cordless.

A few similarities exist in the network functions virtualization (NFV) space. I Read More »

How Important are Physical Routers in the move toward Virtualization?

How important are physical routers in the move toward virtualization?

My one word response would be “very”. But the longer version would start with “it depends”.

Here’s the longer version:

It depends on your perspective. I remember when the Cisco 12000 Series GSR was introduced in the late 90’s. It started an arms race that would last for over a decade. The popular comparison at the time was all about who had the biggest router, or “speeds and feeds” as we used to describe them. 2015 offers us a very different networking discussion. People that design and operate networks are more interested in programmability and virtualization (a.k.a. SDN (Software Defined Networks) and NFV(Network Functions Virtualization). From Frederic Trate’s blog on Application Engineered Routing, you can see why this level of control is such an interesting and important place to start the discussion.

I would argue that in terms of talking points, “speeds and feeds” have taken a back seat in network design. After all, a bunch of static ports and traffic-engineered tunnels don’t lead us to the flexibility and scale that we all seek – or can they? Here are some instances where physical routers are still Read More »

Making Applications and Network Infrastructure Talk

Frederic TrateGuest blog by Frederic Trate, SP Product and Solutions Marketing

One may say this is a topic the telecom industry has been working on for many years and that’s somewhat true. Remember the time when routing protocols and QoS (Quality of Service) mechanisms were the only tools at Service Provider’s disposal to arbitrate between sensitive and non-sensitive traffic? That worked pretty well as long as Service Providers only had to support a few applications – mainly voice and data.

Over time however, as carriers began to converge networks assets into a single, unified IP infrastructure they were faced with the challenge of increasing control over their network infrastructure. Programmability was not yet an industry buzzword but Read More »

Hope for Securing the Internet of Things

I talk and write a lot about the benefits of connecting more things to enterprise networks, and the most frequent concern that I hear is the worry that deploying an industrial IoT will open up thousands more security holes to the network. With an understanding of the new threats and important defenses that come with the IoT, industrial organizations need not let fear prevent them from leveraging the transformative possibilities of Internet of Everything.
