This informative interview with Robert Conger, AVP, ADTRAN, highlights the reasons global service providers and cable network operators are evaluating SDN for their broadband and Ethernet access networks. Operators are faced with new competition every day, whether that is over-the-top content providers or new overlay providers entering their markets. To be successful in this new environment, operators are looking to Software Defined Access (SD-Access) for the service agility and cost savings that are paramount to unleashing lucrative user-driven services that will aid in customer retention and ultimately drive network profitability. Discussion points will include examining the monolithic, big-box network silos that exist today preventing rapid service creation and how deploying an open, programmable and scalable services framework will create nimble and highly scalable access networks. The discussion will wrap up with a snapshot of the next-generation broadband technologies that are being tagged as the first SD-Access deployments as we kick-off 2017.
During the Wells Fargo Securities 5G Forum, Scott Mair, senior vice president of technology planning and engineering at AT&T, discussed the CSP's FirstNet contract, fiber networks and the vital role fiber plays in 5G.
In a proof-of-concept demonstration, Nokia Bell Labs showed how operators can reuse existing FTTH/B deployments to meet the latency constraints and capacity demands for mobile transport in 4G, 5G and IoT networks, and support the one network goal.
Tampere recently began a smart city initiative with partners such as CSP Elisa, leveraging and expanding its fiber infrastructure to use ultra-broadband as the foundation of new digital services around the Finnish metropolis.
Global communications service providers continue to evolve their networks to deliver the user-driven service models and higher bandwidths demanded by consumers. At the same time, 5G densification initiatives are top of mind around the globe, with hundreds of thousands of 5G small cells needing an open, programmable and highly scalable access technology to fuel the growing demand for connectivity. As a result, 5G densification projects will demand fixed-access networks, supporting fronthaul, backhaul and crosshaul applications that provide:
Service agility by applying modern data center principles aligned with DevOps service creation and deployment
Hardware and facilities redundancy offering unprecedented business continuity
Low latency supporting the rigid specifications of the 5G standard
Network elasticity to support service growth to not just multi-gigabit, but multi-10Gbit/s levels
Cost sensitivity supporting mass market services further enabled by Fixed Access Network Sharing (FANS)
With the current maturation of 10G broadband technologies, and the heightened demand for high-speed fixed and mobile connectivity, 2017 is promising to be the year mass-market, multi-gigabit 10Gbit/s fiber services become commercially viable.
NG-PON2 broadband access technology is already in trials with multiple major network operators but is it too early for the commercial deployment of this next generation ultra-broadband technology? In this UBB2020 live radio show, ADTRAN's Kurt Raaflaub provides an update on NG-PON2 developments and chats to Light Reading's Ray Le Maistre about how this technology could play a role in production access networks in 2017.
