Nortel Discovery Protocol
Encyclopedia
The Nortel Discovery Protocol (NDP) is a Data Link Layer
(OSI Layer 2) network protocol for discovery of Nortel
(now acquired by Avaya
and Ciena) devices. The device and topology information is graphically displayed by the Avaya Enterprise Switch Manager
software.
The Nortel Discovery Protocol had its origin in the SynOptics Network Management Protocol (SONMP), developed before the SynOptics
and Wellfleet merger in 1994. The protocol was rebranded as the Bay Network Management Protocol (BNMP) and some protocol analyzers referenced it as the Bay Discovery Protocol (BDP). Four years later, in 1998, Bay Networks
was acquired by Nortel
and renamed to Nortel Discovery Protocol. Possibly changing to Avaya Discovery Protocol (ADP)
The IEEE 802.1AB
or Link Layer Discovery Protocol
that is supported on most Nortel equipment is a standards based (vendor-neutral) protocol that supports multi-vendor environments.
