The Cisco Journey to an IPv6-only Building

...and what we learn from it

October 30, 6pm to 9pm with drinks and snacks

Digicomp, Limmatstrasse 50, Zürich


IT Decision Makers, Architects, Network-, Systems-, Security Engineers, Developers

Is dual-stack a good way to go? What are the experiences with IPv6-only networks? What's best in my case? Many companies struggle with these questions. Cisco has made the step and deployed an IPv6-only campus in San Jose just in order to find the answers to such questions.

This session by Khalid Jawaid presents an engineer’s view of the deployments of dual-stack and IPv6-only that took place at Cisco between 2010 and now. It will especially cover the more recent efforts in introducing IPv6-only across a DC pod and a single campus building, the hurdles in doing that to scale and the impact on user experience. Khalid will discuss the challenges faced from making the business case back in 2010 and deployment across 400 plus remote sites and the lessons learnt along the way. At the end of the session, the audience will take away many new perspectives and inputs for making this kind of decisions for their networks.

This lecture will be held in English
