Scaling NFV Services - The Role of Federation

Dec 8, 2014 by Ramesh Nagarajan

Ramesh NagarajanOperators around the world have embraced NFV as a transformative initiative and are actively pursuing proofs-of-concept and trials to prove the technology. As we move towards field deployments, it is important to consider the needs for scaling NFV deployments and to bake the requirements into the architecture and technology.

The Road Ahead: Reimagining the Third Network

Sep 24, 2014 by Mark Durrett

Mark DurrettThe communications world is undergoing yet another swift, evolutionary shift and it’s bringing a host of new challenges to network operators’ doorsteps. The move to a more fluid, on-demand, and cloud-focused model means being able to react nimbly to changing market and customer needs and expectations, quickly leverage technology innovations, and rapidly capitalize on new service and revenue opportunities. Being able to adapt to this changing environment is key to the continued growth and success of Communications Service Providers (CSP); however, that could be easier said than done.

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.

Behind the Scenes at NFV#5 in Malaga

Feb 25, 2014 by Prayson Pate

Overture CTO, Prayson PateThe European industry body ETSI Industry Study Group (ISG) has been working on Network Functions Virtualisation (NFV) for a year now.  That anniversary was marked by the recent NFV#5 meeting in Malaga, Spain.  Here are a few notes from that meeting.

Meeting Locale

Malaga is in the southwest part of Spain and is not far from Gibraltar.  Several of the attendees took advantage of this fact to participate in pre-meeting day trips down to Gibraltar.  The town of Malaga itself is very pleasant and has a large section of shops and restaurants that make for a pleasant evening stroll and eating adventure. 

Open Service Architecture – the solution to ‘Not another EMS…’

Oct 21, 2013 by Scott Knox

Scott Knox - Director of Solutions DevelopmentService providers have a love-hate relationship with traditional vendor-proprietary EMS (Element Management Systems).  The relationship starts off OK – the EMS provides needed tools to manage a growing network of elements for fault management, inventory management, software backups and some aspects of configuration.  But as the network scales and the services evolve, the vendor-proprietary EMS becomes a bottleneck for growth, service agility and evolution.

Part 2: New Answers for Bringing Scale to the Carrier Ethernet Metro Edge

Sep 10, 2013 by Brian Van Voorhis

How do you define an optimized architecture vision that enables service providers to scale up their service capacity and speed of delivery and migrate from a non-MEF edge/aggregation network to a MEF-compliant network? 

In Part 1 of this series, Problem?  What Problems? we looked at the challenges facing service providers at the network’s metro edge.  In this article we consider options for a potential solution, focusing on the merits of extending MPLS from the core to the edge versus building CE 2.0 on-ramps from the edge to the core.  In the third segment series we will explore an optimized solution that addresses the problems.
