Service Management in the Brave, New, and Virtualized World

Aug 15, 2014 by Ramesh Nagarajan

Ramesh NagarajanThese are exciting times in the world of Network Functions Virtualization (NFV). NFV fever has truly gripped the market and NFV-washing is fully underway. However, there is real progress underneath and beyond the hype.  Operators are beginning to seriously contemplate commercial deployments of NFV, and are devoting considerable effort to the important topic of NFV service management. Network operations teams at the service providers have been asking the difficult questions of how to manage all of the virtual stuff compared to the physical, custom built appliances they have operated in the past.

Delivering the Transition to the Cloud – Lessons for CSPs

Overture CTO, Prayson Pate

I recently had a chat with Russell Fleischer, CEO of HighJump Software, which is a provider of supply chain management software.  HighJump started with traditional onsite approach to software solutions, but has since moved to the cloud.  HighJump’s Chuck Fuerst describes some of the “Benefits Of Cloud In Logistics” in the December 2013 issues of CIO Review, including flexibility, pay-as-you-go, TCO, incremental features and security.  I asked Russell Fleischer about how HighJump uses the cloud to deliver these benefits.  This blog will describe his thoughts, and will also suggest that the lessons learned by HighJump also apply to Communications Service Providers (CSPs).

The idea of Network Function Virtualization (NFV) is separate from that of Software Defined Networking (SDN).  However, for NFV to achieve its full potential, it can’t be limited to converting appliances to software.  NFV needs the principles of SDN to succeed.


SDN, NFV and Future Innovation

Sep 25, 2013 by Prayson Pate

There have been many benefits proposed for using Software Defined Networking (SDN) and Network Functions Virtualization (NFV) to modernize the datacenter and network.  Many of these benefits are fairly near term and quantifiable.  However, the biggest value for SDN and NFV is in the enablement of future innovation and services.





Network Function Virtualization (NFV): the Road Less Travelled - Part 1

Jul 25, 2013 by Ramesh Nagarajan

The communications industry is abuzz with vendor and service provider activities in the NFV space. NFV has the potential to completely transform the way communication networks are designed, built and operated. NFV implements network functions as software entities and takes advantage of cloud technologies such as virtualization and cloud operation tools and techniques.  As such, NFV promises a number of benefits such as CAPEX and OPEX savings, reduced time for service turn up and a shift to a “fail fast” model for new services.  Perhaps even more notably, NFV sets the stage for further innovation in the communications industry by lowering the barrier for entry for newer software-only vendors.

Thinking Differently

Apr 22, 2013 by Prayson Pate

I recently started watching the “Downton Abbey” series, which takes place in the second decade of the twentieth century.  The characters are facing massive changes in their lives due to the rapid evolution of technology, including the growing presence of cars, phones and electricity.  Very quickly the characters will go from viewing these inventions as alien intrusions to being necessary parts of the infrastructure of daily life.  They will change how they think.

In previous blog entries I have covered some of the aspects of applying the cloud to the problem of telecom services.  In this segment I close the loop and talk about how we can apply the concepts previously discussed.  As with the characters in Downton Abbey, making this transition will require us to change how we think.

The Value of Open

In previous blog entries I discussed the value of cloud principles and tools.  A critical aspect of cloud development is the use of applications developed using open interfaces and standard protocols.

Virtualizing the Edge

Mar 18, 2013 by Prayson Pate

In a previous blog entry I discussed some of the technology enablers that led to the success of the cloud, and how they could be applied to other domains such as the metro edge portion of the network.  One key enabler is the use of virtualization and Virtual Machines (VMs) to build the infrastructure of the cloud, which leads to the question, “Can virtualization be applied to the metro edge of the network?” Before digging in further, let’s step back and understand some of the key points of virtualization: abstraction and separation/layering.
