Virtualized Network Functions (VNFs) are only as valuable as the ability to connect them quickly across the network infrastructure for use in building profitable services.



5 Reasons why the Central Office will House the New Telco Cloud

Overture's D. Mark DurrettI've looked at clouds from both sides now. From up and down, and still somehow it's cloud illusions I recall. I really don't know clouds at all. – Joni Mitchell

That classic 1960s Joni Mitchell song – “Both Sides Now” – often played in my home when I was growing up.  And it frequently pops in my head when I reflect on the complex relationship that telecom operators (a.k.a. Communications Service Providers, or CSPs) have with “the cloud.”  Truth be told, there are many more than two sides to this cloud relationship, but the two I’d like you to consider are the following: a) the cloud as a threat to the traditional telco business model and b) cloud technology as an opportunity. 

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.
