A collection of short technical articles

Rethinking Metro Networks

By Marc De Leenheer, Open Networking Lab; and Tom Tofigh, AT&T

To achieve network-wide programmability and observability, open source and vendor-agnostic interfaces are critical. We discuss the re-design of the metro network, demonstrate practical and scalable operational models, and introduce a disaggregated ROADM architecture.

SDN in the Cable Access Network

By Jeff Finkelstein, Cox Communications

With a Compound Annual Growth Rate approximately (CAGR) of 50% over the past few years we may extrapolate what our network consumption will become in the next ten years. At this pace we will outgrow capacity within cable TV head-end facilities. This will cause an increase in complexity, cost and operational impacts as we work to meet customer bandwidth demand. As service providers cable operators are concerned with managing the operational impact and cost associated with this dramatic increase in network requirements.

Impact of SDN/NFV on Business Models

Disruption and Opportunities

By Diego Lopez, Telefonica; Andy Reid, BT; Antonio Manzalini, Telecom Italia; and Marie-Paule Odini, HPE

This paper presents an analysis of the impact of Software Defined Networks and Network Function Virtualization on business models, primarily looking into Service Provider infrastructure and service offering evolution and eluding to some impact also for the vendor ecosystem.
