Innovation through O3 User-oriented SDN


SDN is a technology to innovate new services and to accelerate businessesNetwork will be designed, deployed and operated by

business application and orchestration system

Software-Defined Networking (SDN)

SDN/NFV Future Direction

Enterprise Data center Mobile core

Secure virtual network infra.

Global multiple distributed DCs

Load-based flexible resource allocation

Commercial SDN technologies are mainly applied to “closed domain networks”, such as enterprise, datacenter, and mobile core

5©O3 Project

Open & Agile end-to-end service deployments and operations to satisfy service SLA/QoS for various users

I'd like to automate service management including IT systems.

Northbound API (Innovation for users)

Southbound API (Innovation among vendors)

I'd like to control and operate n/w in fine-grained manner.

Flexible n/w platform for various requests from

users.

I'd like to change AP performance dynamically.

OpenFlow OAM Tools


Topology toolOAM functions for OpenFlow NW is necessary to operate SDN-WAN. To confirm availability of flows, NW topology management and relationship of FlowEntry and flow information is important. NTT Com developed and evaluated topology discovery tools that works under universal circumstances.

Entry managerTo manage flows, it is necessary to create FlowEntry form highly abstracted flow information such as location information, bandwidth and so on. We studied data model that describes necessary information manage SDN networks.

SDN Transport Network Technology with User Control


PurposeProvide a simpler method for user to use a wide area network control technology

that is becoming more complexSatisfy user demand by consolidating management and control of multi-layer

network comprised of packet and opticsTechnology contentMulti-layer management and control (Hitachi, Ltd.)

Based on network resource request from an application, resource management and control feature finds a resource from a lower layer resource pool and allocates it to a higher layer trafficOptical Cut-through technology (Fujitsu, Ltd.) Provide low latency network to user

by configuring an end-to-end optical direct path by using packet and optical core network path
