SDN and Automation

Feb 3, 2014 by Prayson Pate

One of the most powerful aspects of Software Defined Networking (SDN) is its potential to facilitate automation. Rapid and mechanized updates to network behavior and configuration produces not only faster time to service, but faster creation of new services.

Sometimes wrong but never in doubt, here are my predictions for networking in 2014.

 

 

 

NFV Evolution Versus Revolution

Dec 23, 2013 by Prayson Pate

Today's Virtualized Network Functions (VNFs) are somewhat limited in number and variety.  Furthermore, many of these VNFs are fairly simple and evolutionary adaptations of todays’ dedicated network appliances.  This is a good start on the road to Network Functions Virtualization (NFV), but it is not enough.  True progress will require a revolutionary approach.

Overture’s Ramesh Nagarajan has recently written in this space about some of the changes that will be required in VNFs, including elasticity, reliability and management. He also touched on how VNFs can be combined to create new services.  This blog will expand on those topics.

Overture and CloudNFV joined by Telefonica and Sprint in first ETSI NFV Proof of Concept

Dec 16, 2013 by Mark Durrett

Great news on the Network Functions Virtualization front.

You may have read this morning that CloudNFV – the group of vendors Overture joined forces with on NFV – received notification that our proof of concept submission to ETSI was accepted.  There are a couple of public articles that have been published today. We expect to see more later today.

4 Attributes of Openness in Modern Communications

Nov 25, 2013 by Prayson Pate

Openness is one of the most-cited advantages of cloud-based applications, Software-Defined Networking (SDN) and Network Functions Virtualization (NFV).  In this context, what does open really mean?  I posit that there are four key attributes that define openness in this context: documented, standardized, open sourced and inclusive. Any claims of openness by suppliers should be evaluated against these criteria if for no other reason than to clarify their position.

 

 

 

NFV Needs SDN

Oct 28, 2013 by Prayson Pate

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.

 

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.

Update from TIA 2013 - The Future of the Network

Oct 14, 2013 by Prayson Pate

The Federal government may be in a partial shutdown but TIA 2013 "The Future of the Network" was up and running last week in Washington DC.  Here are some observations from the show.

 

 

 

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.

 

 

 

 

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.
