PNNI: ATM Private Network-Node Interface
Private Network-Node Interface (PNNI), a critical ATM network-to-network signaling protocol, provides mechanisms to support scalable, QoS-based ATM routing and switch-to-switch switched virtual connection (SVC) interoperability. The PNNI is a hierarchical, dynamic link-state routing protocol. It is designed to support large-scale ATM networks. PNNI is based on UNI 4.0 and Q.2931.
