IP NGN Network Consolidation
PoP Consolidation Needs
Converge Core-to-edge on one system
High capacity to absorb Core and distribution layers and many intra-POP interconnects
IPoDWDM for Optical WAN convergence
Partition/share resources to reduce capex
Maintain fault and admin isolation Core, Edge, and peering
Dynamic introduction of new services and PoP capacity
Per instance ISSU to enable new features for services edge without having to qualify for all instantiations
Ability to scale the control and data plane as services grow

IPoDWDM
IPoDWDM vs. PMO
IPoDWDM reduces CAP EX Less components,
shelves, processor cards, etc…
IPoDWDM reduces OP EX Less shelves, less rack space, less power,
simplifies trouble shooting, etc…
IPoDWDM enhances Resiliency
Less Opto Electonic
Components, enhanced
fault recovery features,
etc…
