Transformation - the Real Business Case for NFV and SDN

2016 has seen a steady flow of announcements on successful Network Functions Virtualization (NFV) Proof-of-Concept deployments, mostly focused on virtualizing Customer Premise Equipment (vCPE). This has been a relatively straight forward starting point because unlike many other NFV applications, the vCPE use case does not involve complex activities like having to scale in or out individual services. more

Infrastructure for a Connected World

Connected devices need a free-to-use infrastructure that allows for innovation beyond the needs of a provider or other intermediary. An interface is best when it disappears and the user can focus the problem at hand. In the same way infrastructure, is best when it can simply be assumed and becomes invisible. With an invisible infrastructure as with an invisible interface a user can concentrate on their tasks and not think about the computer. Dan Bricklin and I chose to implement VisiCalc on personal computers that people could just purchase. more

How Can You Make More Accurate Capacity Planning Decisions?

Cable operators face a big challenge today as data utilization continues to increase on their networks. Keeping up with the demand for high quality services while upgrading network infrastructure seems to be a never-ending task. Many times, network upgrades are done without much help from tools and systems, leaving it mostly based on experience and performance indicators defined by the operator. Unfortunately, this is the reality for far too many service providers today. more

What’s Holding Back NFV Deployments?

Back in early 2012, the media was all over stack wars that reportedly were taking place between Cisco and VMware. This culminated in VMware's Nicira acquisition in July 2012, paving the way for the coming of software-based networking. Four years later, the market still remains in development mode. Many service providers and enterprises are trying to come to grips with Network Function Virtualization (NFV) and Software-Defined Networking (SDN). more

AfPIF Brings Together Internet Players

If you are passionate about ICT policy, Peering, and Interconnection, then the Africa Peering and Interconnection Forum (AfPIF) is the place to be. The 7th annual AfPIF takes place in Dar es Salaam, Tanzania from 30 August – 1 September 2016.

Internet Access: A Chokepoint for Development

In the 1980's internet connectivity meant allowing general public to communicate and share knowledge and expertise with each other instantly and where it was not possible otherwise. Take the story of Anatoly Klyosov, connecting Russia to the western world for the first time in 1982, as an example. A bio-chemist who was not allowed to leave the soviet territory for security reasons. The internet enabled him to participate in meetings with his counterparts at Harvard University, University of Stockholm and beyond. more

WiFi QoE Assurance with TR-069 - Part 3: From Single AP to Large AP Deployments

Last week we investigated how rich data derived from TR-069 can be used to optimize the service quality of a single access point (AP) within the subscriber premises. Often a service provider will control multiple APs within a multi-dwelling unit, university campus, or other public space. This opens up new doors for optimizing service quality - instead of simply optimizing a single AP, you are now able to control other APs in the vicinity as well. more

The Digital Divide Has Persisted over the Life of the Internet

People have been trying to measure the global diffusion of the Internet and the digital divide between rich and poor nation for twenty five years. The first to do so was Larry Landweber, who noted whether or not a nation had an Internet (or other) connection. It was a binary metric -- yes or no -- and it was suitable to its time because there were only a handful of users who were restricted to teaching and research, using a few applications like email, file transfer, news groups and remote login. more

WiFi QoE Assurance with TR-069 - Part 2: Optimizing a Single Access Point

As we have seen in the first installment of this series, TR-069 offers unprecedented visibility into the customer premises network to highlight devices beyond the gateway, and in the case of WiFi, the issues affecting service quality. Insights into the surrounding WIFI landscape alone provide ample data to provision the access point (AP) to operate in a part of the spectrum with the least amount of interference. more

WiFi QoE Assurance with TR-069 - Part 1: The Toolbox

Subscribers today expect to be connected at all times with exceptional service quality. For communication service providers operating in urban environments, multi-dwelling units (MDUs) are a big cause for concern. Delivering consistently high WiFi service quality in high-density environments is a challenge. The sheer number of nearby access points, electronics, and outside influences can result in a host of WiFi service quality issues... more
