Network Virtualization and SDN": Akihiro Nakao, Professor, University of Tokyo, Japan

Speakers:1. “SDN in China”: Liu Duo, Vice President, MIIT/CATR,

China2. “Defining NFV: NFV - Network Function Virtualization”:

Yun Chao Hu,  Co-Chair,Infrastructure WG,  ETSI ISG NFV

3. “SDN standardization in ONF: OpenFlow, SDN Architecture, and other work items”: Fabian Schneider, Vice-Chair, Framework and Architecture WG, ONF

4. “ITU-T SG13 Views”: Takashi Egawa, Q14/13 Rapporteur, NEC, Japan

Summary and Conclusions (2)

2

1. Programmable (or Software definable) capabilities are one of long time visions of network study and becoming in real

2. Programmability is being extend the scope: SDN (C-Plane) and DPN (C-Plane & D-Plane)

3. Objectives for applying programmability: Virtualization, Capacity, Dynamic, Flexibility, Cost and Efficiency

4. Involved SDOs: ONF, NFV, IETF, OpenDaylight, OIF, BBF and ITU-T SG13 and SG11

5. Issues for further consideration and developments:a. NV (Network Virtualization), NFV(Function), SDN, Carrier

SDN, ITU-T SDN and DPNb. Programmability for in-network processing and for new

(non-IP) protocolsc. Data-Plane Programmability Interfacesd. Accommodation of multiple isolated programmable

environments6. ITU-T needs to extend/accelerate their work and take a role

for globally interoperable standard developments collaborating with relevant SDOs, academia and institutes

Proposed Action Items

3

1. Identify scope asap: NV (Network Virtualization), NFV(Function Virtualization), SDN, Carrier SDN, ITU-T SDN and DPN

2. FG-Carrier-SDN• Focus Group vs. On-going work in Study Groups: Work scopes,

Recommendations and time to market• Focus Group vs. JCA: co-ordination and collaboration3. Issues for further consideration and developments (possibly

FG-DPN by Keynote):• Programmability for in-network processing and for new (non-

IP) protocols• Data-Plane Programmability Interfaces• Accommodation of multiple isolated programmable

environments4. Any others:• Minimize conflict of other SDOs standards with ITU and

maximize interoperability• FG-Carrier-SDN vs. FG-DPN (?)
