Implementing Gmpls Uni; Prerequisites For Implementing Gmpls Uni - Cisco CRS Configuration Manual

Implementing GMPLS UNI

The Generalized Multiprotocol Label Switching (GMPLS) User Network Interface (UNI) creates a circuit
connection between two clients (UNI-C) of an optical network. This connection is achieved by signaling
exchanges between UNI Client (UNI-C) and UNI Network (UNI-N) nodes, where UNI-C nodes are router
nodes and UNI-N nodes are optical nodes.
A GMPLS overlay model is required to connect packet routers with the optical network in these scenarios:
• Different groups within a service provider are responsible for managing packet and optical networks.
• The optical and packet network are managed by different service providers.
• There is a weak trust model between the entities operating the optical and packet networks.
