SDN/MPLS 2015

Multi-domain nationwide SDN orchestration

• Growing demand for communication services that can be

seamlessly provided from anywhere in the world

• By using the centralized control, several communication

services to be promptly established and provided across

networks can be realized.

– It is difficult due to numerous reasons, such as immense processing

and the dependency on all technologies.

The need for generic control functions and a control

orchestration protocol

The NBI of the SDN/OpenFlow or GMPLS/ PCE Controllers are typically

technology and vendor dependent.

The multi-domain SDN orchestrator shall implement different plugins for each of the

specific controller’s NBI.

The STRAUSS project defines a generic functional model of a control plane for the

provisioning of connectivity, topology dissemination and path computation, and

defines an associated protocol (the Control Orchestration Protocol - COP-)

The COP would be able to be used as the East-West IF of different orchestrators.

Realizes the wide-area multiple virtual

networks on an existing L3 network by

using an overlay method.

Improves availability of customer

service by a combination of SDN

centralized control and autonomous

path switching.

Reduces CAPEX/OPEX by providing

a network virtualization on the wide-

area network with generic IA servers.

Fujitsu’s software switch “Fujitsu Network Virtuora SN-V” to support resource

virtualization for a wide-area network

Realizing carrier-grade software switching on an IA server

High-speed data communication with Fujitsu’s proprietary packet processing technology

Autonomous path switching in addition to SDN centralized control

Compliant with OpenFlow1.3 standard interfaces

SDN/MPLS 2015

Future Carrier Network Architecture using

simple general-purpose servers and switches Maintaining reliability and scalability is brought by advanced and unified control of modularized

switch and server groups as virtual resources using inexpensive equipment.

General-purpose switches working together with network controller and packet optical transport

system will result in highly reliable and flexible networks.
