This post on opendaylight.org summarizes the intersection of SDN and NFV with topology diagrams and examples from presentations by AT&T at the NFV World Congress Event this month. Automation in service delivery and integration with existing billing and back office systems remain key selling points for SDN and NFV with service providers. It’s becoming apparent that a hierarchy of controller and orchestration functions will be necessary to implement an SDN and / or NFV enabled network across a carrier’s footprint. Examples of these include local and global SDN controllers that manage connectivity and cloud orchestrators that manage compute resource allocation.
Residential and business broadband demand is increasing. Cisco Visual Networking Index estimates that global Internet traffic increased by 30% in 2014 to 77 exabytes and is expected to exceed 100 exabytes in 2016. The largest contributor to this increasing figure is video content, which makes up more than half of the traffic being consumed on the Internet. As video consumption and total Internet traffic rises, even current fiber technologies such as GPON will not be able to keep up with the increased demand. Luckily, the Full Service Access Network (FSAN) and the International Telecommunication Union (ITU) are rising to the challenge by firming up their standards on NG-PON2, which promises speeds over 10x that of current PON technologies. This post reveals three exciting characteristics of this emerging access technology.
