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.

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.

The Foundation for a Business Relevant Network

With the growing influx of new mobile devices, connected things, bandwidth intensive applications and more data, the network is more relevant to business success than ever before.  Back in June of 2012, Cisco saw that we needed to move away from multiple network systems loosely linked together to an agile and simple infrastructure, streamlined policy and centralized management would be needed to support new business demands. We called it Cisco Unified Access and we aligned the solution to three pillars: One Network, One Policy and One Management.

For the last few years, we have focused on delivering new products and functionality under this Unified Access model. Below is a timeline of products released as part of the Unified Access framework. Cisco lead the way in delivering gigabit 802.11ac Wi-Fi., converged wireless control in access switches and through the acquisition of Meraki – a complete cloud-managed network solution.

The timeline above doesn’t represent every feature and function we have delivered, but it shows Cisco’s commitment to this Unified Access model, both from a cloud-managed and on-premise solution perspective.

Today, Cisco is announcing a number of new products and new functionality to existing products that will help mobilize the workforce, secure the business and increase IT agility. The announcement includes the following: Read More »
