Telco Virtualization: Bottoms up and Tops Down. Seriously

by Keith Brody Nov 08, 2017

Here’s the third (and final) part of our review of Heavy Reading’s recent OSS in the Era of NFV/SDN conference in London. Even if the event raised many more questions than it provided answers, that alone is a pointer to the present state of virtualisation in telco networks.

Policy and Machine Learning in Virtualized Network: Not if, but When (and how?)

by Keith Brody Nov 07, 2017

Our last blog started our review of Heavy Reading’s OSS in the Era of NFV/SDN conference in London. Here, we continue with our report which, as already mentioned suggests that the state of the two virtualisation technologies in telco presently raises many more questions than it provides answers.

NFV/SDN is Clear as Mud

by Keith Brody Nov 06, 2017

If Heavy Reading’s OSS in the Era of NFV/SDN conference in London yesterday is any barometer, the state of the two virtualisation technologies in telco is, well, as clear as mud. As analyst James Crawshaw put it in his introductory presentation, in ‘Hype Cycle’ terms we are in the ‘Trough of Disillusionment’. There’s not much hype about that.

IoT Blog Series: 5G: The Need For Speed

by Lars Månsson Oct 31, 2016

While LTE appears to have become the face of 4G, for all the introductory hype the final nature of 5G networks remains unclear not least with the question of standardization still evolving.  So in talking about it – as the entire industry seems to be doing –, one appropriate question to ask is: “Are we getting ahead of ourselves? Do we really need to worry about 5G yet?” Perhaps. We’ll come back to that in a minute. First, though, let’s lay out what we do know about 5G.

IoT Blog Series: What is the Internet of Things?

by Keith Brody Oct 31, 2016

In the rush to become active (or even expert) in the Internet of (Every)Things (IoE/IoT) there’s an increasing amount of noise. But as with most high-profile trends the hype tends to run ahead of real insight. DigitalRoute’s blog is only one of many places where you’ll probably be bombarded with the term IoT so we thought that rather than jumping in with the solutions, a better starting point might be defining the questions.

Blog Series: Deploying an NFV: Part 3

by Thomas Brännström May 30, 2016

In the previous two blogs in this series, we’ve raised a number of issues that we’d advise you to address when deploying Mediation as a VNF in an NFV infrastructure.  We’ll conclude our guidance in this article, with the second part of our look at the specifics of an actual deployment.  Once again, remember that this isn’t intended to be a comprehensive checklist for NFV success; our aim in this blog series is to alert you to important considerations in advance of the task at hand.

Blog Series: Deploying an NFV: Some more things to think about

by Thomas Brännström May 27, 2016

In our last blog, we raised some general points readers might want to think about when deploying Mediation as a VNF in an NFV infrastructure. We’ll continue that theme here, but move on to issues directly related to the specifics of an actual deployment. Remember, this isn’t a comprehensive checklist for NFV success: our aim in this blog series is to alert you to important considerations in advance of the task at hand.

Blog Series: Mediation in NFV: Some things to think about when it comes to deployment (Part 1)

by Thomas Brännström Apr 22, 2016

Picking up from the previous article, in this blog we’ll begin look in more detail into MediationZone deployed as a VNF in an NFV Infrastructure, provided by an NFV-I vendor. Our goal here is to give you some question of questions you will want to answered to deliver a successful NFV implementation. This is not an exhaustive checklist, but it does highlight key considerations if you are to achieve your goals.

Blog Series: Why go Virtual and what’s involved?

by Thomas Brännström Apr 18, 2016

In the first two blogs in this series we touched the differences between Cloud deployments and NFV scenarios. In general terms, the latter is one manifestation of the former. Now, let’s dig into a little more detail about the different “flavours” of deployment involved and the choices the telco faces when it comes to virtual deployment.

Blog Series: Getting to Grips with NFV part 2 - Infrastructure

by Thomas Brännström Apr 01, 2016

In the first blog, we noted that ETSI is leading the NFV standardisation process.  To some extent, because it’s software based rather than physical (i.e. what’s being standardised in the case of NFV is a function and also its attendant interface so defining what the function should do and how the interface should look are not of equal importance), this means the horse of standardisation doesn’t need so strictly to come before the cart of deployment.  This to some extent explains why early NFV installations are rife before standards are finalised.
