new SDN application
› Integration of Cloud and Service Provider SDN
controller platforms
› Statical analysis and dynamic
troubleshooting
› SDN for Home
networks
› Connectivity management on
mobile devices
Problem to solve
› Evaluate different design choices
› Improve networkperformance
› Leverage the SDN
platform for new applications
› SDN architecture and design
› New features added to existing protocols
› New applications built
on top of SDN

› Service chain: An ordered list of services (NAT, firewall, DPI, etc.)
› Dynamically derived from subscriber, application, and service ordering policies
› Unidirectional: different upstream and downstream service paths
› Multiple service paths per subscriber
