multilane link
multilane link. A communication link between HP NonStop™ Cluster Switches that can
consist of multiple ServerNet cables. Two-lane links and four-lane links are examples
of multilane links.
multimode fiber-optic (MMF) plug-in card (PIC). A plug-in card (PIC) for the modular
ServerNet expansion board (MSEB) and I/O multifunction (IOMF) 2 customer-
replaceable unit (CRU) that supports the multimode fiber-optic (MMF) interface.
multimode fiber-optic (MMF) ServerNet cable. A fiber-optic cable that either allows more
than one mode to propagate or supports propagation of more than one mode of a
given wavelength. MMF ServerNet cable typically supports shorter transmission
distances than single-mode fiber-optic (SMF) ServerNet cable.
multiplexed. The action of separating data traffic from one line onto several distinct lines or
of combining data traffic from several distinct lines onto one line.
NAM. See Network Access Method (NAM).
national-standards-body conforming POSIX.1 application. An application that both:
•
Uses only the facilities described in ISO/IEC IS 9945-1:1990 and approved
standards of a specific member of the ISO or IEC (the national standards body).
•
Documents use of only those facilities and approved standards and documents all
options and dependencies on limits.
native link editor. See nld utility.
native mode. See TNS/R native mode.
native system library. Synonym for implicit library.
$NCP. The process name of the network control process.
NEC. National Electrical Code.
network. Two or more computer systems (nodes) connected so that they can exchange
information and share resources. See also Expand network, wide area network (WAN),
and local area network (LAN).
Network Access Method (NAM). The interface through which an Expand-over-ServerNet
line-handler process communicates with the ServerNet cluster monitor process
(SNETMON).
network control process. A process pair, named $NCP, that runs in each system of an
Expand network. $NCP establishes and terminates system-to-system connections,
maintains network-related system tables (including the network routing table, NRT),
calculates the most efficient way to transmit data to other systems in the network,
monitors and logs changes in the status of the network and its systems, informs
$NCPs at neighbor systems of changes in line or Expand line-handler process status,
