SDN Controller vs. Carrier Management System Attribute
SDN Controller Management Systems
Primary goal Enable Programmability to applications
Provide FCAPs to the network
Control model Logically centralized Embedded into devices
Connectivity Flow Connection
Operations model Automation Manual
Object model Service-oriented Physical-oriented
Device interface Control forwarding Configure/monitor devices
Southbound protocols
OpenFlow TLI, SNMP, NetConf, etc.
Advantages Agile, flexible, intelligent, elastic Established interfaces and processes
Drawbacks Organizational impact Slow, unreliable, rigid

SDN and Openness
ONF/SDN Architecture
Standard Interface
Open Platform
• Common framework • Multi-vendor software • Abstraction from apps
AND underlying devices
• Standard, programmatic interfaces
• Open/common device data models
Network Functions Virtualization
• Why? • Accelerate time to new services
• Optimize resource utilization
• Improve operational efficiency
• What? • ETSI NFV Industry Spec. Group
(formed 4Q2012)
• How? • Collaboration to drive platform
requirements and standards
• Who? • 28 of the world’s leading carriers
