Leverage SDN Principles in LTE to Meet Future Network Demands

PLATFORM FOR PROFITABLE GROWTH The Role of SDN in LTE Networks SDN refers to specific technologies considered promising for mobile network evolution Separation of the control and data planes - allows sophisticated traffic management to be driven by software, rather than purely by hardware routers Network virtualization - the implementation of network components in software and the replacement of dedicated, proprietary hardware with commoditized IT platforms Service exposure - : although not strictly overlapping with SDN, service exposure seems to be integrated in current vendor strategies to help operators expose network functionality to third parties more effectively

SURVEY RESULTS How Does The Market Perceive The role of SDN in Mobile Networking

BUILDING THE NEW MOBILE NETWORK Leverage SDN Principles to Meet Future Network Demands 1 2 3 Dramatic Growth Accelerated Change Increase Service Velocity Bandwidth usage generally grows to meet capacity. Smartphone users consume more data over time. Beyond smartphones and tablets, M2M will drive increased network usage. To manage growth, mobile network operators are faced with near constant change. The new mobile network must simplify the deployment, provisioning and management of new services/ capacity The traditional business model for mobile providers is shifting from voice/sms to data. Networks must evolve to become platforms for service delivery open, dynamic, flexible.

Demand CAPACITY ON DEMAND Leverage SDN Principles to Meet Future Network Demands 1 Dramatic Growth Planned Investment Actual Demand Planned Demand 2 3 Accelerated Change Increase Service Velocity Time Capacity on demand, better resource utilization.

ADD CAPACITY, NOT COMPLEXITY Leverage SDN Principles to Meet Future Network Demands 1 2 3 Dramatic Growth Accelerated Change Increase Service Velocity Linear network growth drives exponential provisioning complexity. Adding capacity as VMs dramatically reduces provisioning.

CALL TO ACTION The Role of SDN in Mobile Networks SDN may introduce new types of services and breath new life into MNO business models Although SDN and virtualisation technologies are not yet standardised the software nature of the concepts allows MNO s to deploy now and upgrade to standardised components via software when available Service opportunities and integration with third parties are considered a major opportunity Start in the data centre, OSS and BSS and core networks to drive down TCO and offer new types of services whilst exploring more complex deployments in the edge and RAN
