Operational Challenges Abound, and Not Always Tech Related

By | Blog | No Comments

This is a topic I have written on a while back, but it is so important it seemed to deserve a revisit, with a slightly different view than I approached it from before. In the last few weeks we have been discussing with a client this very issue. This client is nearing the launch of a production trial of their NFV environment with a small group of friendly customers. We have worked with them on processes, the issues they can expect to see, and what they should do if/when each of…

The Current State of NFV: Virtual Network Functions

By | Blog | No Comments

  This may be one of the shorter blogs in this series, as it is very straightforward. In this one I want to focus on Virtual Network Functions, where they are today and where they are headed. In recent years, as cloud environments have become more and more common, vendors have begun creating virtualized versions of their network gear. Whether it is Nokia/ALU, Juniper, Cisco, or whoever, they all have a version of their major products that they have inserted a “v” in front of to enter the virtual arms race….

The Current State of NFV: Standards

By | Blog | No Comments

There are two standards out there right now that have strong momentum. One being the ETSI NFV standard that has been around for quite a while, and the other being the recently open sourced Enhanced Control, Orchestration, Management and Policy (ECOMP) architecture from AT&T based on the work done as part of Domain 2.0. ETSI has been the leader in this space, and is the standard that almost everyone is using. It is also a less complicated view of what is required to successfully create and manage an NFV environment. There…

The Current State of NFV: Introduction

By | Blog | No Comments

We are going to be posting a series of blogs over the next few weeks to cover where we see the NFV landscape right now, the issues we see still outstanding, an assessment of the maturity of various layers to the NFV reference architecture (considering both the ETSI NFV and AT&T ECOMP frameworks), and where we see things moving in the future. Itential has spent the last 2 years or so working with clients in a hands-on capacity trialing various tools and solutions for SDN and NFV. We have at a…

vCPE: Why Should You Move This Direction?

By | Blog | No Comments

Today most Internet customers have one or more pieces of Customer Premise Equipment (CPE) that provide services and capabilities to them. Access points generally provide services such as wired and wireless connectivity, Ethernet switching, DHCP, NAT, QoS routing, firewalls and other security features. With the introduction of Virtual CPE (vCPE), there remains the need for a physical device at the customer premise (pCPE), but this device can be much less complex, handling only the physical connectivity and the local switching. The remainder of the functionality can be virtualized and moved to the cloud.  So why should these services…

Here Comes Virtual CPE!

By | Blog | No Comments

An exciting application of SDN and NFV technologies is emerging into the mainstream in the last couple of months, and boy is it a popular topic in blog posts.  This topic of growing interest is virtual customer premise equipment (vCPE). If you are still a little in the dark with regard to what exactly vCPE is and how to virtualize something that has to sit at the customer premise for you to hook a wire into then keep reading! The vCPE idea is quite simple in concept even if it can be…
