The Open Networking Summit (ONS) kicked off on March 4 in Santa Clara, Calif., and attendees took to Twitter to cover keynote talks, offer commentary and discuss key. From panel discussions covering the importance of open source technologies to top vendors breaking down their SDN and network functions virtualization (NFV) strategies, Twitter was the place to go to recount some of the most memorable moments from this year's ONS. We scoured the social media platform and gathered the best commentary from the most talked-about panel discussions and keynotes, as well as comments and opinions from ONS attendees.

The importance of being 'open' for the future of computing and networking
SDN expert Guru Parulkar kicked off the event's first keynote, which also included panelists Najam Ahmad from Facebook, Dan Pitt of the Open Networking Foundation, Jim Zemlin from the Linux Foundation and Jono Bacon from Canonical. Parulkar stated the importance of preparing for SDN to go mainstream, while pointing out the various areas of the network that SDN impacts. From programmability and infrastructure to new revenue streams and the reduction of Opex and Capex, the five panelists had a lot to say about how "openness" is key to the success of computing and networking going forward.

Transformation, innovation, and SDN and NFV at AT&T
John Donovan, senior executive vice president at AT&T, took the floor and discussed AT&T's SDN strategy in his keynote speech. AT&T is focusing its efforts on its User-Defined Network Cloud, a multi-tenant platform built on both NFV and SDN. The four principles that play a major role in AT&T's strategy with its platform include openness, simplicity, scalability and security. Donovan reiterated that the company is undergoing a major overhaul and is changing up a number of aspects, including how the network is built, the equipment and software used, how the company is buying, and AT&T's operations and culture.
AT&T will devote its entire capital budget on radically altering its architecture to SDN and NFV for on-demand network services #ONS2014— Rivka Gewirtz Little (@RivkaLittle) March 4, 2014
#ONS2014 should be called the NFV show. Keynotes heavily dominated by operators looking to shift service provisioning with NFV/SDN— Rivka Gewirtz Little (@RivkaLittle) March 4, 2014
AT&T's approach to "user-defined network cloud" could spell trouble for incumbents who are used to bulk orders from it. #ONS2014— Shamus McGillicuddy (@ShamusTT) March 4, 2014
AT&T will not do overlay networks. They will toe-tag old infra and invest in new SDN/NFV tech. #ONS2014— Shamus McGillicuddy (@ShamusTT) March 4, 2014
John Donovan said AT&T's architectural shift to SDN and NFV will not impact Net Neutrality. #ONS2014. Don't agree.— Shamus McGillicuddy (@ShamusTT) March 4, 2014
AT&T says it will build a carrier grade open source community -- that's the way to get NFV into production quickly. #ONS2014— Rivka Gewirtz Little (@RivkaLittle) March 5, 2014
Someone just described AT&T keynote at #ONS14 as a battle cry. Going virtual, limiting legacy, not working with incumbent vendors.— Rivka Gewirtz Little (@RivkaLittle) March 5, 2014
SDN as a disruptive technology
Venture capitalist Vinod Khosla, technologist and investor at Khosla Ventures, spoke about SDN's role as a disruptive technology and the importance of this change in the industry. He touched on cost changes, the complexity of SDN and why it's necessary to have flexibility.
Andromeda SDN at Google
Amin Vahdat, distinguished engineer at Google, gave insight during the show into Google's infrastructure services, codenamed Andromeda. These services include network virtualization in Google's internal networks, allowing the company to provide SDN control of the entire hardware and software stack. Vahdat spoke about the challenges that come with network virtualization, including isolation, distributed denial-of-services attacks and even NFV. He continued to explain the inner workings of Andromeda and shared case studies from Google.
"Logically centralized/hierarchical control plane with peer-to-peer data plane beats full decentralization" Amin Vahdat #ONS2014— afewell (@afewell) March 5, 2014
#ons2014 Bullet on Google slide re "Andromeda" controller: "Virtualize SDN". Hmm.— Lisa Caywood (@RealLisaC) March 5, 2014
Google - net virtualization needs to provide improved L3 routing, security, HA, centralized management. #ONS2014— Lee Doyle (@leedoyle_dc) March 5, 2014
Google highlights the need to orchestrate l2-L7 horizontally across the entire network. Vertical and horizontal orchestration. #ONS2014.— Andre Kindness (@AndreKindness) March 5, 2014
Amin Vahdat's keynote makes the case for virtualized networks for service chains, need for QoS. #ons2014— Don Clark (@burlingamer) March 5, 2014
