Nokia Siemens, Juniper Work on IP, Optical Network Interoperability

By Vivek Naik, TMCnet Contributor

Nokia Siemens Networks, part of the telecoms company Nokia (News - Alert), reportedly announced that it has entered into contractual agreement with Juniper Networks for the companies to compose a comprehensive solution that enables smooth transition and interoperability between Internet Protocol (IP) and optical networks.

Nokia Siemens Networks (News - Alert) officials said that the companies are collaborating together to develop the lowest possible cost effective solutions that deliver the maximum possible efficiency 10 Giga bit Ethernet (GbE), 40 GbE and 100 GbE networks for IP over Dense Wavelength Division Multiplexing (DWDM).
This effort is well aligned with current trend that emerged from a recent market research analysis, which claims 80 percent of the quarter on quarter growth in 2008 was accounted for by the increased deployment of 40 Gigabit Dense Wavelength-Division Multiplexing (DWDM). Another report had predicted the (Optical Transport Market) OTE market would experience a significant slowdown in 2009, and pick up in 2010 and continue to grow steadily till 2013. All other global trends, including the substantial increase of broadband usage indicate that the OTE market revenues will eventually grow via the Gigabit DWDM route.
The company said that the solutions would also combine holistic management integration and Generalized Multiprotocol Label Switching (GMPLS) control plane functioning across the two differing networks.
Collaborative efforts, such as this one between Nokia Siemens Networks and Juniper Networks (News - Alert), are in keeping with one of the seven mantras of the time, which dictates that organizations must make serious efforts to reach out and work with each other. The seven guidelines for succeeding in current economic environment are collectively called the CES (News - Alert) 7 and were pronounced and initiated at the Consumer Electronics Show (CES) 2009.
Nokia Siemens Networks says that implementation of long-haul DWDM optics on router line interface cards will increase network efficiency by eliminating the need for redundant transponders, and will, however, pose network management challenges because IP and optical networks are traditionally managed separately, and now will have to be jointly handled in terms of interoperability. 

The two companies propose to sculpt a solution that manages the entire router-to-optical link as a single offering, claim officials. The router-integrated optical DWDM interfaces from Juniper's T Series Core Routers, which
enable sophisticated processing on a true multi-service platform, will interoperate with Nokia Siemens Networks' hiT7300 WDM platform and be managed by the company's carrier grade Transport Network Management System (TNMS).
