Converged Packet-Optical Software Defined Networking

Date: Tuesday, September 15th, 2015, 6:30 PM
Location: Cadence / Bldg 10, 2655 Seely Ave, San Jose, CA (map)
Speakers: Tom Tofigh, PMTS AT&T and Marc De Leenheer, Scientist and Developer, ON.LAB
Time: 6:30 PM (PT) Networking/Refreshments, 7:00 PM Presentation


Service Provider Networks are complex and multi-layer in nature. Today, Provisioning and adding bandwidth requires order of days if not months. Since packet and optical networks are managed independently, each one of them has to be overprovisioned to deal with traffic anomalies and failures. This leads to lack of service agility and is a significant source of capex and opex overhead for the network operator.

This talk provides an overview of multi-layer optimization platform specific to packet-optical SDN (Software-Defined Networking) implementation for Wide Area Networks. Tom & Marc will review multilayer network abstractions performed at ON.LAB, including flexible packet-optical bandwidth sharing and on-demand network applications, such as Bandwidth Calendaring, on demand networks, and traffic engineering options. Tom & Marc will show how a converged SDN Control plane for packet and optical networks can help address many network inefficiencies.
