Panel #1: Algorithmic and Data Aspects of NFV-SDN

Date: November 13th 

Time: 15:00-16:15

Moderator: Sandra Scott-Hayward

Panelists: Nate Foster, Brian Kelley, Levi Perigo


NFV and SDN technologies enable new data and algorithmic approaches to be applied to the deployment and operations of telecommunications networks. For example, routing and switching resources can be dynamically reconfigured based on adaptive algorithms. These algorithms can take into account many different metrics, such as availability of infrastructure, security and privacy, bandwidth pricing, and carbon footprint, latency, or resilience.

Besides, NFV & SDN technologies enable new kinds of network monitoring and surveillance techniques to predict and rapidly adapt to network events such as congestion, route & node failures and of course, to detect and isolate security threats.

Panelists are invited to outline their views on the opportunity and impact of new algorithmic and data-driven capabilities, enabled by NFV and SDN, together with the steps they think the industry needs to take to realize the opportunities fully.

Panel #2: System and Performance Aspects of NFV-SDN

Date: November 14th 

Time: 15:00-16:15

Moderator: Don Clarke

Panelists: Ying Zhang, Andrea Fumagalli, Sridhar Rajagopal


NFV and SDN technologies present significant opportunities but also new operational challenges for network operators. The difficulties of specifying and integrating these new systems were foreseen but have not yet been fully solved. As a minimum, NFV implementation and operations need to deliver the deterministic performance, security, and reliability that differentiates telecommunications networks from other types of networks, even as technologies and markets change, and regulations evolve in different jurisdictions.

The long term persistence of telecommunications networks as critical national infrastructures means that organizational change is necessarily incremental. New skills need to be acquired and need to coexist with existing ones as operators evolve to accommodate these new technologies alongside the existing networks. Hence, it is likely to take several more years for NFV to reach maturity because of the critical nature and sheer scale and complexity of the industry.

We invite our panelists to highlight areas in systems and performance that they think are the most important to address in the short term, their benefits, and what actions are needed. We also invite panelists to outline how they think network operators and their industry partners can smoothly evolve their operations to make the best use of these technologies.
