Ryan McCowan, fiber access product manager for ADTRAN, recently participated in an UBB2020 webinar on mobilizing SD-Access with 10G PON. Having some prior knowledge of the subject at hand, I still find different points of view to be very informational as I continue to track these emerging technologies. Items I found particularly interesting were:
There is a lot of talk about software-defined networks (SDN) and network functions virtualization (NFV). But so far, the discussion has largely left out the access networks — mobile, broadband, and voice connections to the customer — which are crucial to building a full SDN and NFV platform. What exactly is required to build software-defined access (SD-Access)?
What good are SDN and NVF if they are incompatible with the technology that connects to the customer? Billions of customers worldwide require a connection to the first hop in the network, known as the last mile, which means that somewhere there is a piece of technology that must connect to the network from the customer premises, a device known as customer premises equipment (CPE).
To rapidly roll out new NFV services that can be controlled on an end-to-end basis, service providers need an open SD-Access platform that integrates with NFV. This platform needs to be open, flexible, and programmable, enabling configuration of the underlying access hardware to be made via software.
There is a huge trend underway in technology: The move from pipelines to platforms. Platforms have displaced pipelines to take the business world by storm – whether it’s a video platform such as YouTube or a housing platform such as Airbnb. The same trend is taking hold in the telecom world, where service providers need to respond by building open platforms for the telco cloud.
Let’s start defining pipelines vs. platforms. The concept has been described by authors Marshall W. Van Alstyne, Geoffrey G. Parker, and Sangeet Paul Choudary in the book, Platform Revolution, as well as in an article published in the Harvard Business Review (HBR) last year, titled, “Pipelines, Platforms, and the New Rules of Strategy.” A pipeline, according to the authors, creates value by controlling linear activities in a value chain. Think of the way you buy a cable service, then get a cable box, then buy movies from the cable company. Platforms, on the other hand, connect producers and consumers with a higher value exchange. An example is the Apple App Store.
The most successful services today, whether it’s the iPhone, Netflix, or Airbnb, are platform models that have created rich ecosystems that deliver a huge amount of value toconsumers. The platform gives the consumer a tool to get access to what they want whenever they want it.
The diversity of today’s client device types has grown far and wide from Bring Your Own Devices (BYOD) to Internet of Things (IOT) to Augmented/Virtual Reality with each its own unique connectivity and roaming decision making behaviors. Ensuring an exceptional Wi-Fi end user experience is challenging – especially when client devices, with their limited view of the network, are ultimately in charge of the decision of what access point (AP) to connect to, when to roam and at what speed.
As we enter the 2017, we are faced with a different landscape, one which will see changes in the economic rules of engagement with other European nations, and likely the United States. In this new era, in order to preserve competitiveness, it is vital that the leaders of nations recognise the importance of the next wave of digital infrastructure. Success or failure in the digital economy is what will make or break the economies of the future.
This year’s Veterans (age 50+) World Championships were held from October 10-16 in Stralsund, Germany, hosting 700 participants and thousands of fans from around the world. As with every sporting event, fans expected to be able to share their experience while at the venue.
Brexit is a good example. Following the surprise vote for Britain to exit the European Union, I saw multitudes of news outlets and scores of tweeters announcing the end was coming. When did we get so fearful of change instead of embracing the value that it can potentially bring to our businesses?
