Juniper, NSN team for IPoDWDM-like effort

Juniper Networks and Nokia Siemens Networks have announced a joint effort to create router interfaces to optical networking equipment and components, an approach that is being likened to Cisco Systems' IP-over-DWDM architecture. IPoDWDM has been around for several years, and Cisco has at least two network operator customers of note for it--Sprint and Comcast. 

The cost benefits and management simplifications of eliminating hops between gear may be finding more fans amid increasingly cost-conscious carriers. As Telephony notes, some carriers have questioned the ability to achieve complete visibility of an optical signal in such an architecture. In the Juniper-NSN scenario, the latter firm's management system manages the optical signal, and is integrated with NSN's hiT7300 multi-reach DWDM gear and the 10GE DWDM cards on Juniper's routers.
