Challenges and Opportunities
Challenges
• Innovation at devices and OTT side
• Number of devices explode data and signaling traffic with unexpected peaks
• Single purpose elements inflexible with high ASICs development cost
• Revenue trends for Comms Service Providers and Network Equipment Providers force more cost reduction, operational efficiency
Opportunities
• IP everywhere: BB/LTE, Core, Cloud
• LTE opportunity to re-engineer the network and IT with frontier blurring
• Cache, profile and inspect traffic more efficiently
• Virtualization and Cloud mature in the Data Center, SDN trend
• COTS servers now supporting Gb Ethernet data processing

What is SDN
Abstraction of control plane from forwarding hardware • Network control plane as a centralized software program
• Centralized intelligence of network topology
• Dynamic and programmable network, interaction with applications
• Implemented via variety of methods including OpenFlow protocol
Key Benefits • Provides opportunity for rapid innovation in networking
• Use cases for all types of networks including Enterprise Campus, Service Provider, Cloud, Data Center
• Can enable simplified management through network virtualization

Use Case Summary Nb Name Description
#1 Appliance Migration Migrate proprietary boxes to COTS servers, decouple Data & control plan, leverage SDN protocols, controllers, centralized controller for multiple data plane components etc
#2 Traffic Steering Introduce SDN with controller to extract 1st packets, tag flow and avoid having to redo this for all packets. Allow dynamic change
#3 Content Delivery Traffic routing Allow dynamic traffic routing thanks to SDN controller and dynamic view of available NW resources
#4 Virtual Core IMS Enhance Policy with tight integration with SDN controller to route traffic to virtual core IMS
#5 Networking as a Service Extand IaaS with dynamic NW resource allocation and allow Telecom operators to offer this as a Service to external customers
#6 Edge policy Enforcement Have a centralized control but distributed enforcement model for Security policies.
#7 Cloud Bursting Burst from Private Cloud to Public Cloud and be able to orchestrate the dynamic secure network in the public cloud
#8 Optimal Traffic Engineering Inter-DC WAN Ability to have a Stateful controller to more dynamically place flows in the network, to best utilize the network resources
#9 Data Center Virtualization Ability to move workloads around from any server to any other server within a DC without limitations of the network addressing
