I had an opportunity this week to look over some material from Netcracker on their notion of a “digital service provider”, part of the documentation that relates to their Agile Virtualization Platform concept. I also reviewed what was available on the technology and architecture of AVP. I find the technology fascinating and the research and…
One of the persistent questions with both SDN and NFV is how the service management or lifecycle management processes would work. Any time that a network service requires cooperative behavior among functional elements, the presumption is that all the elements have to be functioning. Even with standard services, meaning services over legacy networks, that can…
Overlay networks have been a topic for this blog fairly often recently, but given that more operators (including, recently, Comcast) have come out in favor of them, I think it’s time to look at how overlay technology might impact network investment overall. After all, if overlay networking becomes mainstream, something of that magnitude would have…
I blogged yesterday about the OPNFV project for Event Streams and the need to take a broad view of event-driven software as a precursor to exploring the best way to standardize event coding and exchange. It occurred to me that we’re facing the same sort of problem with IoT, focusing on things that would matter…
One of those who comment regularly on my blog brought a news item to my attention. The OPNFV project has a new activity, introduced by AT&T, called “Event Streams” and defined HERE. The purpose of the project is to create a standard format for sending event data from the Service Assurance component of NFV to…
Operators want open source software and they want OCP hardware, or so they say. It would seem that the trend overall is to stamp out vendors, but of course neither of these things really stamp out vendor relationships. They might have an impact on the buyer/seller relationship, though, and on the way that operators buy…
At the TMF event in Nice Verizon opened yet another discussion, or perhaps I should say “reopened” because the topic came up way back in April 2013 and it was just as divisive then. It’s the topic of “microservices” or breaking down virtual functions into very small components. NetCracker also had some things to say…
There is an inescapable conclusion to be drawn from recent industry announcements: Vendors have lost control of SDN and NFV, which means they’ve lost control of the evolution of networking. Operators, in a state of self-described frustration with their vendors’ support for transformation goals, have taken matters into their own hands. I’ve gotten emails over…
One of the most logical places for operator interest in open-source software to focus is in the area of virtual network functions (VNFs). Most of the popular functions are available in at least one open-source implementation, and operators have been grousing over the license terms for commercial VNFs. It would seem that an open-source model…
These are the times that try the souls of networking sales management. Most of you know that I have an ongoing dialog with salespeople in many companies, and that dialog says that network spending overall is under pressure. Legacy infrastructure investment is slow-rolling because of ROI issues, and vendors who have presented next-gen architectures have…
