Internet Engineering Note (IEN)
datagram. ICMP also includes an echo request/reply used to test whether a destination
is reachable and responding.
Internet Engineering Note (IEN). A series of notes developed in parallel to RFCs and
available across the Internet from the INIC. IENs contain many of the early theories on
the Internet.
Internet Protocol (IP). The Internet standard protocol that defines the Internet datagram as
the unit of information passed across the Internet, and that provides the basis for the
Internet, connectionless, best-effort, packet-delivery service.
interoperability. The ability of software and hardware on multiple machines from multiple
vendors to communicate meaningfully.
IOP. Input/output process. An input/output process (IOP) is a privileged process, residing in
a NonStop system processor, which provides an application access to a
communications line.
IP. See Internet Protocol (IP).
IP datagram. The basic unit of information passed across the Internet. An IP datagram is to
the Internet as a hardware packet is to a physical network. It contains source and
destination addresses, along with data.
ISO. See International Organization for Standardization (ISO).
ITU-T. See International Telecommunications Union Telecommunications (ITU-T).
LANMAN. See LAN manager (LANMAN) process.
LAN. See local area network (LAN).
LAN manager (LANMAN) process. The process provided as part of the ServerNet local
area network (LAN) systems access (SLSA) subsystem that starts and manages the
SLSA subsystem objects and the LAN monitor (LANMON) process and assigns
ownership of Ethernet adapters to the LANMON processes in the system. Subsystem
Control Facility (SCF) commands are directed to the LANMON processes for
configuring and managing the SLSA subsystem and the Ethernet adapters.
LANMON. See LAN monitor (LANMON) process.
LAN monitor (LANMON) process. The process provided as part of the ServerNet local
area network (LAN) systems access (SLSA) subsystem that has ownership of the
Ethernet adapters controlled by the SLSA subsystem.
Link Access Protocol —Balanced (LAPB). ITU-T standards that define in the Data Link
Layer the requirements for X.25 connections over wide area networks (WANs).
