Virtuora® OTN Control Suite
Software-defined applications that automate and control OTN services

Global network traffic, driven by mobility, social media, cloud
commerce, big data, and the Internet of Things, is projected to
increase demand for data services beyond the capabilities of
existing networks. Many service providers are struggling to
meet this growing demand with typical optical transport
network operations that take months to introduce new revenuegenerating services. Other providers are starting to design
leading-edge transport networks that deliver additional
capacity, higher spectral efficiency, and lower cost per bit.
Key strategies include adopting the concept of a centrally
controlled, software-defined network and optimizing the
existing available resources of a converged, multilayer network.
The architecture must enable an on-demand, automated, and
highly programmable transport network to meet the crucial
requirement for increasing network performance without costly
capital investments.
One way to improve network resource utilization, optimize the
traffic running on the network, and manage capacity and inventory is to
automate Optical Transport Network (OTN) service provisioning.

Virtuora OTN Control Suite
The Virtuora OTN Control Suite includes these applications:

The Virtuora OTN Control Suite is a set of software-defined control
applications designed to automate OTN services, such as:

■■ Service

■■ Wavelength

partitioning
and allocating pieces of the network into
smaller segments
■■ Virtualizing the bandwidth within a wavelength
■■ Providing protection and restoration in a wavelength
■■ Selecting the services that are protected inside a wavelength
■■ Subdividing

The Virtuora OTN Control Suite automates these services using
applications that reside on top of the Virtuora Network Controller (NC).
Each Virtuora OTN application includes a set of external interfaces to the
controller; analytics and data collection engines; active and available
inventory; and BSS/OSSs. Because these external interfaces comply with
open REST standards, Virtuora OTN applications can be used with any
controller that supports the same standards.

Resource Discovery
After a network has been installed and commissioned, the Resource
Discovery application automatically discovers all topology elements.
Resolurces discovered include equipment, nodes, and links. The
application updates the network inventory state to indicate that
resources are installed and ready for service. As wavelength and subrate services are provisioned, the circuit and utilization inventory is
updated and available for automated capacity monitoring.
Service Activation
The Service Activation application engages with the optical layer and
assesses the capacity on the layer, as well as the physical bandwidth.
From there, it can activate an optimized service with or without
constraints, provide a new path when a protected or non-protected path
goes down, or route around faults that trigger a network alarm.

Modular OTN Applications for the Disaggregated Network

Once a path has been designed, the Service Activation application
performs the necessary provisioning and reports successful completion.
The circuit is reported as an abstract router link to the controller, and a
record of the circuit details is maintained in the Virtuora inventory data
store.
Service Restoration
The Virtuora Service Restoration application enables service providers to
provision and restore services automatically or on-demand, ensuring
resilient networks and avoidance of SLA breaches.
Network services are restored based current network conditions and
traffic load. If a critical service goes down, the Service Restoration
application can invoke the Path Computation application, automatically
move service to an available route, and then gracefully revert to the
original path once conditions clear.
OTN Path Computation
The OTN Path Computation application is different from traditional path
computation in that it has the power to function in a multilayer,
multivendor, multidomain network, as opposed to residing at the node
or switch level. The Path Computation application considers available
equipment as well as infrastructure links when selecting a path.

The Virtuora Product Suite
The Virtuora Network Controller and supporting Virtuora applications
demonstrate the value of disaggregated SDN architecture, an opensource controller, and modular applications. By separating the control
functions from the hardware and logically centralizing and managing
them, Virtuora customers gain the ability to work across multiple
devices, layers, and vendors quickly, efficiently, reliably, and best of all—
automatically.
By implementing a Fujitsu Virtuora solution, you can:
■■ Cut

long-term operational and capital costs
up service launch and delivery
■■ Maintain support for current revenue-bearing services
■■ Preserve the useful life of existing network assets
■■ Choose equipment and technology without vendor dependence
■■ Improve quality of service and customer experience
■■ Quickly identify, anticipate and meet customer needs
■■ Open up a rich ecosystem of new revenue opportunities
■■ Speed

Triggered by a request from the controller or the service activation GUI,
the path computation engine dynamically computes an optimal path
based on routing constraints, such as available bandwidth, network
faults, and diversity. SRLGs and intra-office fiber information can be
imported into the inventory data store, allowing Virtuora to manage the
fiber connecting the optical network to the routed network.

Every Virtuora application can take
advantage of Virtuora Path Computation.
Because its output is in the form of a REST
call with the best path calculated,
separate, integrated systems like the NFV
Orchestrator can use it. Even proprietary
OSS/BSS systems can leverage it.

Expert Integration Services for Custom
SDN/NFV Solutions
A Full Range of Support and Integration Services
Fujitsu offers a wide range of expert services to support successful
implementation of the Virtuora Product Suite.
Some of the main benefits of SDN are the end-to-end automation and
integration of all elements in the SDN ecosystem, including network
elements, management functions, controllers and orchestrators.
Integration of these systems is built around standard interfaces and
data modeling of services and functionality.
The VIRTUORA components provide a REST interface supporting all
functionality available in a Fujitsu SDN solution. These REST interfaces
can be used to integrate into other components within the SDN
ecosystem. Fujitsu Services can analyze the systems to be integrated
and develop interface mapping to support custom functionality beyond
that of the VIRTUORA platform.
YANG Model Development and Maintenance
YANG modeling is utilized to model behavior between various layers of
the SDN solution. As new services and components are added to the
SDN architecture, the YANG models need to be updated to include
support for these changes. Fujitsu Services can provide new or updated
YANG models based on new service definitions, new or updated
equipment, and other changes. The new YANG models can then be used
in the SDN environment to provide the new or updated functionality.
