SDN in Mobile Broadband Networks Advancing the transformation of the network architecture into a highly efficient and flexible software infrastructure, ensuring best customer experience Nurit Sprecher Presented at MPLS SDN World Congress 2014, Paris France, March 18-21, 2014
Agenda Market drivers 2020 network architecture vision Various SDN domains and related use cases End-to-end orchestration and management Opportunities and challenges Conclusion 2
The thirst for mobile data will continue to grow exponentially. 3D, high and ultra-high definition screens Video integrated everywhere Digital universe continues to expand Everything from and on the cloud Billions of connected objects 3
Challenges for operators Requirements for the network are constantly changing Become a valued service supplier in the new digital economy Develop and launch new services rapidly and cost effectively Have the business and technical agility to address new application requirements and business partnerships 4
NSN vision: Mobile networks will enable the profitable delivery of one gigabyte of personalized data per user per day. Key requirements for networks towards 2020 Support up to 1000 times more capacity Reduce latency to milliseconds Teach networks to be self-aware Flatten total energy consumption Reinvent Telcos for the cloud Personalize network experience for profitability and a quantum leap in flexibility 5
Cloud Computing, NFV and SDN Highly complementary, innovative, architectural concepts and paradigms that together have the potential to support profound transformation regarding the way in which mobile broadband networks are implemented, deployed and operated Ecosystem for innovation Personalized experience Rapid introduction of new services Optimized TCO Holistic end-to-end based management and control Agility 6 *) IaaS, PaaS and SaaS: Infrastructure, Platform-and Software-as-a-Service
