Technology Description

IPoDWDM

IPoDWDM is a network architecture approach that integrates layer 1 (optical) and layer 3 (IP) technologies by combining DWDM transponder features and functions into the router interface. Instead of being limited to a short-reach gray wavelength, the router is able to emit a tunable, ITU-grid compatible colored wavelength, with G.709 Digital Wrapper and Enhanced Forward Error Correction (EFEC) functions. This combination provides multiple advantages, including savings in capital and operational expenditures due to the elimination of multiple transponder shelves, cross-connect shelves, and associated short-reach interfaces. The total number of optical-electronic components is reduced by 50 percent, further lowering costs, improving availability, lowering the time needed to provision services on the network, and increasing mean time between failures (MTBF). It also halves the number of patch cables needed at the terminating sites, reduces power consumption, and shrinks the overall physical footprint of the equipment.

Note Cisco ANA version 3.6.6 and later provides support for IPoDWDM only on CRS-1 devices running IOS-XR software.

Information Model Objects (IMOs)

This section describes the following IMOs:

DWDM Interface

The DWDM Interface object represents a DWDM controller physical termination point. It is accessed by the Module containing it.

Vendor-Specific Inventory and IMOs

There are no vendor-specific inventory or IMOs for this technology. Currently, only the Cisco CRS-1 device running IOS-XR is supported.

Network Topology

There is no network topology to be discovered specifically for IPoDWDM. The command line interface (CLI) is used to discover physical inventory attributes for DWDM controllers in the chassis. Cisco ANA models them as it does other physical ports.

Service Alarms

The following alarms are supported for this technology:

•DWDM Controller up/down

•DWDM G709 Wrapper up/down

For detailed information about alarms and correlation, see the Cisco Active Network Abstraction 3.7 User Guide.
