Virtuora® OTN Control Suite

Software-dened 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 revenue-

generating 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.

The Virtuora OTN Control Suite is a set of software-defined control

applications designed to automate OTN services, such as:

■Wavelength partitioning

■ Subdividing 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

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.

Virtuora OTN Control Suite

The Virtuora OTN Control Suite includes these applications:

■Resource Discovery

■Service Activation

■Service Restoration

■OTN Path Computation

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 sub-

rate 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.

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.

The Virtuora Product Suite

The Virtuora Network Controller and supporting Virtuora applications

demonstrate the value of disaggregated SDN architecture, an open-

source 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

■Speed 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

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.
