Patrick Moore, Itential, LLC

Patrick has been in the Telecommunications and Information Technology fields for 20+ years. Beginning in 2000 he took on a leadership role in the implementation of networks for voice and data for a CLEC in the Southeast. Prior to that he held various technician roles for both wireless and wireline carriers maintaining networks in the field and at switch sites. Patrick transitioned to a vendor role with Alcatel-Lucent as his career progressed, managing teams of analysts, architects, and developers responsible for OSS solutions across the Americas Region. In the last few years at Itential he has been involved in the emergence of SDN and NFV by assisting clients with the evolution of their networks to the new paradigm of a programmable network, leveraging both vendor and open source solutions.
Abstract: This talk will focus on:
1 - The journey involved in network automation, at a high level
2 - Programmability as an approach to automation
3 - Legacy and Future Automation approaches
4 - Vendor Hype: NETCONF/YANG and NFV
5 - The reality we face today
6 - An approach to future network automation

Programmability is the ability to manage network devices in a similar manner to the way you can manage software and servers in an IT environment today. We are gradually seeing the emergence of network devices that present APIs for use in managing them, such as the Cisco Nexus devices. This is opening up new automation possibilities.

There is an architecture, and open source tools such as NAPALM, that make this more of a reality as time progresses, as well. This architecture/toolset allows programmable automation to be applied to legacy equipment that isn't otherwise capable.

Lastly, there is a common misconception that NFV is going to automatically be programmable since it is virtualized, but most VNFs out there today are just revisions of the same software from the physical device placed on a virtual machine. The result is a virtual device with all of the same limitations, in many cases MORE, than the physical device itself had. To make NFV programmable in the near term will require the same architecture as discussed for legacy network devices.
