IPoDWDM is Crossing the Chasm

Cisco IPoDWDM solutionThe survey results are in. They confirm that service providers are ready to go mainstream with IP over DWDM (IPoDWDM). More than half of the respondents plan to deploy IPoDWM within a year. Eventually over 85% of them will do so beyond 2012. Infonetics Research carried out a global survey recently on packet-optical convergence technologies for routers including IPoDWDM, OTN and others. It published the findings for its clients on July 16th under the ‘Carrier Routing Switching and Ethernet’ Continuous Research Service.

The motivation for developing IPoDWDM for us was simple. By integrating colored optics as interfaces within routers, providers could reduce the need for external optical-electrical-optical (OEO) transponder racks, cross connects and SONET/SDH switching layers. This dramatic network simplification resulted in lesser number of devices in the network, thus lowering maintenance, power, cooling and rack-space operational expenses. Additionally, routers now had direct visibility into layer 1 optical transport network (DWDM) leading to innovative resiliency features like Proactive Protection.

Comcast lead IPoDWDM implementation in its core network with 40 Gbps Packet-over-SONET/SDH (POS) cards and the 10 Gigabit Ethernet (GE) cards for the CRS family in 2005. Several customers followed suit- T-Com (Germany), Sprint (USA), Netia (Poland), Free (France), KazakhTelecom (Kazakhstan) and others as IPoDWDM was developed on other platforms like the 12000, 7600 and ASR 9000. As a matter-of-fact six of the top twenty global providers have adopted IPoDWDM.

In the last few years we have seen other vendors follow-up with their IPoDWDM solutions, endorsing the approach. While the industry continues to deliberate on the future of packet-optical convergence, with the emergence of 40/100 GE and OTN switching, we’ve been quietly executing on meeting customer needs with IPoDWDM, an innovative packet-optical convergence strategy.
