1 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

2 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

3 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

4 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

5 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

6 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

7 A fully automated and programmable mobile-broadband network, orchestrated over a network-wide, uniform cloud platform, is essential for survival. 7 *) NFV: Network Function Virtualization; SDN: Software Defined Networking

8 Mobile-network architecture transformation towards

9 Network abstraction and potential SDN domains towards

11 Demonstrated Software Defined Networking Flexible reuse of existing infrastructure to guarantee best experience Move the network to the subscriber Reduce TCO: Telco cloud and ease of operation Make your network flexible Optimize and automate your network Demonstrated at MWC 2014 Ben Video App usage call Home Ann John Data center App CAM* Operator Control Center Video call App usage 1 Data center 2 App 3 SGW Video call App usage 1. Re-assign transport capacity SDN 2. Instantiate application clone CAM 3. Program virtual GW SDN+CAM Event *) CAM - Cloud Application Manager 11

12 SDN use cases relating to mobile-broadband backhaul network Mobile Backhaul 12

13 SDN use cases relating to Radio Access Network (RAN) virtualization 13

14 Liquid Applications distributed resources within the RAN Resource optimization Agility Simplicity Increase responsiveness from the edge Acceleration Real-time network and service analytics Insights Unparalleled user experience Business value Agile application development and deployment Innovative services 14

15 Orchestrator and management applications 15

16 Conclusion The SDN concept and its architectural principles can (a) complement cloud computing and Network Function Virtualization in mobile broadband networks and (b) advance the transformation of the network architecture into a pure software infrastructure which is highly efficient and flexible. Enables mobile operators to: Provide on-demand resources that are capable of dealing with unpredictable data growth while ensuring best customer experience Introduce new levels of automation in network and service management achieved by the programmability and abstraction level of the network as well as drastically reduce TCO per gigabyte Offer mobile networks that supply additional agility and flexibility, ensuring faster innovation cycles for top-line growth. Key factors for success: multi-vendor support and gradual migration Requires new operational processes and people skills 16
