5.6. Control of ATM Networks: The P-NNI Protocols
In ATM networks, Virtual Circuits (VCs) provide connectivity between two ATM end points. An ATM VC is a logical circuit with associated bandwidth, delay, and other service parameters. The P-NNI protocols, described next, provide the routing and signaling capabilities required for establishing and deleting VCs. It is quite feasible to adapt these protocols for use in optical networks, and hence it is instructive to look into their details.
5.6.1. The P-NNI Hierarchy
Private Network-Network Interface (P-NNI) denotes both the interface between border switches in two ATM subnetworks as well as the interface between two switches within a network.[3] The ATM Forum P-NNI specification defines automated ...
