Aria Networks, a leading provider of forecasting, planning and optimisation software solutions for Next-Generation Networks (NGNs) today announced enhancements of its support of Wavelength Division Multiplex (WDM) network planning within its iVNT Optical software.

Transparent optical networks, based on WDM with ring or mesh architectures and dynamic control and management, offer the potential for telecoms operators to reduce equipment and operational costs, better leverage their network assets, and improve the availability of services to their customers. Fully leveraging these optical networks requires sophisticated planning software that can cope with the complexity of balancing many simultaneous routing parameters, many complex network rules and policies, and can cope with the increasing scale of optical networks. Telecoms operators are turning to integration of such planning systems with their network inventory systems, optical network control planes (such as provided by GMPLS and ASON), and activation systems to fully realise the business benefits.

Aria’s iVNT-Optical has been enhanced to extend the support of equipment types deployed in today’s optical networks and to provide additional policy control of wavelength-based services, enabling flexible combinations of user-defined or preference-based network policies. Aria has also extended the support of iVNT’s proven multi-processor routing engine to the optical domain, providing iVNT Optical with the performance required to handle the largest and most dynamic optical networks in the world.

Aria has also fully integrated iVNT Optical with its existing iAdapt and iCustomise frameworks to provide easy integration with third-party systems and flexible, customisable planning. This enables Telecom operators to rapidly federate iVNT Optical with existing management systems, network control planes and other products from Aria’s iVNT Suite to realise an end-to-end and automated planning capability.

“Since the initial development of iVNT Optical through our collaboration with KDDI, iVNT Optical has been used to plan some of the largest and most complex next-generation WDM networks,” said Dr. Jay Perrett, CTO at Aria Networks. “We have leveraged the experience of working on networks with hundreds of thousands of wavelengths and enhanced iVNT Optical to ensure it can stay ahead of the challenges these networks present – such as the need for more control, more performance, more integration and an ability to customise and automate planning tasks. Planning systems can’t operate in isolation, they need to be effectively and easily integrated in to the existing operational support systems and control or management planes.”

iVNT Optical enables Capital Expenditure (CAPEX) for WDM network infrastructures to be effectively deployed at the right time and the right place, and reduces Operational Expenditure (OPEX) by removing manual and labour intensive processes. iVNT Optical can operate with networks that use no control or management plane, or can optionally be integrated with dynamic management and control plane architectures such as those provided by GMPLS or ASON.
