• My mission at NICT

• Making optical packet & circuit integrated switching node

stable, operatable, and interwork with SDN

• And others …

• How for the 1st _mission?

• Verification of optical nodes and networks

• Test on field optical fibers

• Use nation‐wide SDN/Openflow test environment

• _Interop_test_with_other_optical_systems

 User view: A “high‐speed, inexpensive” service and

“low delay, low data‐loss” service on a single optical network

 Network provider view: Large switch capacity (>100Gbps

Optical Packet), energy saving, and flexible & efficient resource

use under a simple control

RISE

 RISE = Research Infrastructure for large‐Scale network Experiments

 Reorganized our OpenFlow network environment on JGN2plus as a testbed

 Ver. 1.0: started to accept public users (October 2011)

 Ver. 2.0: multi‐user model (April 2012)

 We now provide OpenFlow‐based user‐slices in which users can use their own

controllers

• Need to dynamically setup high-volume pipe via multiple core/metro/access optical networks for data centers

• Ability to create optical paths with flexible bandwidth based on data center request over multiple optical networks.

What I am Thinking is …

• Our optical packet switch looks up part of (“whole of” in future) IP

address so IP and optical work together simply.

• _Circuit_‐_switched_part_is_solid_(although_upgrade_to_100Gbps_or

400Gbps is another issue)

• Packet‐switched part may be modified according to SDN

operators’ requests.

• Cloud and DC requests SDN, SDN configures optical core, metro,

and access properly.

• Not covered in my talk but

• ID‐based communication lies in the access (mobile hosts and

fixed/mobile server) for mobility, heterogeneity and security.

• Automatic installation as well as path computation is also

useful to (Optical) SDN.
