IRTF SDN RG

• Nov’12 – Research Directions

• Data Plane

– More flexibility and programmability (incorporation of custom hardware, software)

– Incorporating richer set of functions (e.g., middleboxes)

• Control Plane

– Higher-level languages for programming SDNs

– Testing and debugging SDNs

– Exploring new domains for policy specification, etc.

Software Defined Antenna (SDA)

• Computer program that takes as input the desired operational frequency, polarization, beam gain and pointing angle and creates a pixel pattern to yield the antenna array.

ITU-T Future Networks and Cloud • Requirements

– Programmability of Network resources

– Orchestration of Network resources and apps

– Logically centralized control and separate SDN control from Network resources

– Abstraction of underlying network resources - data models

– I/F for customized behavior of network resources and control

– Management of Physical and Virtual Network Resources

ATIS NFV Forum Inter-NFV Provider • Businesses to innovate on new

services by chaining virtualized functions from another physical network operators

• The “home” service provider instantiates virtualized network functions in the “visited” service provider’s tenant domain thus ensuring service availability and continuity in roaming scenarios for any kind of services.
