Nokia Siemens, Juniper, attend to IP-optical networking

Nokia Siemens Networks and Juniper Networks have twined their fortunes even further, announcing yet another joint foray merging IP and optical networking.

Juniper is contributing its IP routing expertise to the collaboration, while Nokia Siemens Networks is offering its dense wavelength division multiplexing (DWDM) transport technology, including operational management systems for both technologies. The two said they are jointly developing 10G, 40G and 100G IP over DWDM products, with management integration and GMPLS control plane interworking.

Siemens had been a Juniper reseller long before it merged operations with Nokia in 2006. Juniper had also supplied equipment to Siemens rival Alcatel-Lucent and to Nokia competitor Ericsson. Since the Nokia Siemens merger, Juniper has been gradually moving into a tighter orbit with Nokia Siemens.

In February, Juniper and Nokia Siemens kicked their partnership up a level when they announced they would collaborate on products for the carrier Ethernet market (story here). That led to the formation in June of a joint venture, 60 percent owned by Juniper and based in the Netherlands (story here).

"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," said Opher Kahane, senior vice president and general manager of the High-End Systems Business Unit at Juniper Networks. "The combination of IP and optical transport technologies increases the efficiency of the network, and we are very excited to be working with Nokia Siemens Networks to bring this innovative solution to market."

The implementation of long-haul DWDM optics on router line interface cards will increase network efficiency by reducing the need for redundant transponders, but it can present network management challenges because IP and optical networks are traditionally managed separately, the pair explained.

To address these concerns, Nokia Siemens Networks and Juniper are creating a solution that manages the entire router-to-optical link as a single entity. Using Juniper's T Series Core Routers, the router-integrated optical DWDM interfaces will interoperate with Nokia Siemens Networks' hiT7300 WDM platform and will be managed by the company's carrier-grade Transport Network Management System (TNMS).
