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 »

A Groundbreaking Study in Service Provider Cloud Managed Business Solutions

Last week at Mobile World Congress was incredibly busy and there were many compelling announcements. In case you missed it one that we’re especially excited about was about how Light Reading commissioned the European Advanced Networking Test Center (EANTC) as an independent party to validate Cisco’s Cloud Managed Business Solutions.

This study is truly groundbreaking as it’s the first effort of its kind to evaluate Read More »

Cisco Live Milan: Service Provider Business Transformation Straight Ahead

Igor PhotoGuest blog by Igor Dayen, SP Product and Solutions Marketing
Cisco Live Milan 2015 has just concluded and concluded with a bang of record-breaking attendance and increased customers’ understanding of the IoE and service provider Technologies. In my first post-show blog, I focused on the overall booth offerings and discussed relevance of Evolved Services Platform (ESP) and Evolved Programmable Network (EPN) to service providers’ success and the importance of properly addressing their requirements. I decided that it is important enough to provide additional highlights on the Cisco Live event.   Before I share with you the remaining demo information, I wanted to recap the technologies that I described in the first post-show blog:

  1. nV Technology to simplify operations in the Network edge
  2. Segment Routing to enabled SDN-based routing and simplifying network operations
  3. Operational Simplicity enabled by Autonomic Networking in the Access
  4. Network Service Orchestration using Tail-f
  5. Virtualized Managed Business Services: delivering Cloud VPN

The above mentioned technologies are key innovations and bring a wealth of choices to the service provider when they create and deliver services to their business and residential users.
