I-PNNI

(Integrated-Private Network-to-Network Interface) An extension to the PNNI routing protocol used in ATM networks that enables IP routers to select paths through the network based on quality of service (QoS). I-PNNI was never completed by the ATM Forum and was superseded by MPLS. See PNNI, MPLS and QoS.

I-PNNI routing envisions a mix of technologies in the same network: R/S edge devices near power workgroups, traditional routers in low traffic areas and ATM switches in the backbone.

I-PNNI routing is based on proven technology, and has its roots in standard, open routing protocols that have been in use for years.

Network architectures and configuration choices

I-PNNI extends the capabilities of PNNI routing to the IP protocol, including quality of services (QoS) routing and the ability to scale networks.

I-PNNI enhances and complements the activities underway currently in the ATM Forum's Multiprotocol over ATM (MPOA) Working Group and in the Internet Engineering Task Force (IETF).
