Nokia Siemens Networks and Juniper Networks to Integrate IP and Optical Technologies to Improve Network Efficiency and Reduce Operator Opex

As trends such as video, virtualization and cloud computing continue to drive the need for core networking capacity, operators will be looking for ways to scale their networks efficiently and cost-effectively.

Nokia Siemens Networks (NSN) and Juniper Networks announced they are combining their respective strengths in Optical and IP networking to create a solution that brings the two complementary technologies closer together to provide operators with a highly flexible, reliable and cost efficient way to scale their networks to manage growing volumes of data, voice and multimedia applications.

The integrated IP-Optical solution brings together world-class IP routing expertise from Juniper, and world-class Wavelength Division Multiplexing (DWDM) transport technology from NSN, including operational management systems for both technologies.

As carriers consolidate their IP and DWDM environments to ensure cost efficient growth, the solution will start to break the barriers between optical and electrical layers. The implementation of long-haul DWDM optics on router line interface cards will increase network efficiency by reducing the need for redundant transponders, but can present network management challenges because IP and optical networks are traditionally managed separately. To address these concerns, NSN and Juniper are creating an innovative solution which manages the entire router–to-optical link as a single entity.

The scope of cooperation includes the development of cost-optimized 10G, 40G and 100G IP over DWDM solutions with management integration and GMPLS control plane interworking. Using Juniper’s T Series Core Routers, the router-integrated optical DWDM interfaces will interoperate seamlessly with Nokia Siemens Networks’ hiT7300 WDM platform and be managed by the company’s carrier grade Transport Network Management System (TNMS).

The joint solution will improve overall efficiency in the network; and the operator will be able to enjoy faster service provisioning times as only one DWDM interface will need to be installed and configured, not to mention improved reliability through early link failure detection, enhanced troubleshooting and overall simplicity.
