List of terms

network interworking function (NIWF)

The FR-ATM network interworking function (NIWF) enables frame relay CPE connectivity across frame relay networks interconnected over a backbone ATM network. The NIWF encapsulates frame relay traffic over ATM and multiplexes many frame relay DLCIs to one ATM VCC. The FR-ATM network interworking function is based on the FRF.5 standard.

See also, FR-ATM interworking service (page 56).

network management interface (NMIF)

An interface between Nortel Multiservice Switch nodes and external entities for management purposes, using a specific protocol. The supported interface and protocol types are: local, Telnet, Ssh, FMIP, and FTP (both non-secure and secure).

network management interface system (NMIS)

Manages interfaces between the Nortel Multiservice Switch software and external network management systems. Through NMIS, commands can be issued to Nortel Multiservice Switch nodes from network managers, and results returned. This allows Multiservice Switch nodes to be controlled and monitored.

network mask

A 32-bit value that masks (or causes a router to ignore) portions of a packet’s address. This technique allows the administrator to subdivide the logical network from the IP address.

network processing unit

A programmable device that specializes in the processing of data packets.

network protocol

A protocol that consists of an address plan, a frame format, and a state machine for the protocol's behavior.

network service access point address

An address used in ATM-based services (for example, PORS and Circuit Emulation) to identify objects in a network. It is defined in RFC 1629 and in ATM USER-Network Interface (UNI) Signalling Specification (Version 4.0), released by the ATM Forum Technical Committee, July 1996.

network time protocol (NTP)

A public network time synchronization protocol that Nortel Multiservice Switch XNTP software can use to synchronize the time between different nodes in a network. RFC 1305, Network Time Protocol (Version 3), defines the standards for this protocol.
