Cisco DNA Assurance for Next Generation WIreless: Isolate problems for faster troubleshooting – BRKEWN-2034

You do not have time to deal with network issues anymore. In the past you would design RF coverage, build the WLANs, hope for the best, and react to alarms and user complaints. This logic would force you to constantly react to fire drills, running every day to assess issues as they were reported to you. What if you could benefit from tools that would anticipate these issues, instead of simply reporting once they occurred? The logic of the Cisco Digital Network Architecture (Cisco DNA) is not only to provide an abstraction for automation and policies, but also provide a virtuous feedback loop, allowing you to visualize the consequences of your configurations. Intelligent analytics allows you to observe trends, work on what-if scenarios, and be warned about issues before they actually explode and collapse your network. In this session, you will get a deep dive exposure to the new Cisco DNA Center Assurance tool, to monitor trends in your network, anticipate issues, get intelligent (human readable), meaningful and synthetic messages on the state of your network, your clients and their applications, and easily troubleshoot issues once you identify an unsafe trend.

Optimize your WLANs for small and mobile devices (phones, tablets and alike) – BRKEWN-2003

Smartphones and tablets often represent 60 percent or more of your WiFi clients, and people use voice and video calls on these devices while roaming.

Voice Over 5G Mobile Packet Core – BRKSPM-2017

The 5G specifications developed by 3GPP have completed the specifications for voice support for both non-standalone (5G NSA) and 5G standalone (5G SA) networksThe completion of 5G NR specifications for standalone (SA) has been approved by 3GPP. Also, after the 5G NR specifications for NSA, standardization of 5G at the first stage is pretty ready. Although the main drivers for 5G evolution is data, voice and video servcies are still very important as SPs will not be able to keep the voice on their LTE netwrok for a long time. At the beginning, 5G uses the LTE voice network and to provide those services using existing IMS architecture. The 5G radio technology is NR and the voice services called VoNR in 5G. In this session, the presenters will speak about the various 5G architecture options that SPs are planning to use and the voice/video evolution over each option. Cisco packet core and 3GPP experts will provide a comprehensive view on those options including: 1-CSFB–>VoLTE–>VoNR for Option 3X, 2- EPS or RAT FB / VoLTE –>VoNR for option 4/4a, 3- EPS or RAT FB / VoLTE –>VoNR for option 2, etc. After this session, audience will walk out with a better understanding on Vo5G and the evolution path options that large service providers are taking during their journey for 5G Network
