interoperability
interoperability. The ability of software and hardware on multiple machines from multiple
vendors to communicate meaningfully.
invalid address. An address that is not assigned to any interface. A valid address becomes
invalid when its valid lifetime expires. Invalid addresses should not appear as the
destination or source address of a packet. In the former case, the Internet routing
system cannot deliver the packet; in the latter case, the recipient of the packet cannot
respond to it.
IOAM. See Input/Output adapter module (IOAM).
IOP. Input/output process. An input/output process (IOP) is a privileged process, residing in
a fault-tolerant system processor, which provides an application access to a
communications line.
IP. See Internet Protocol.
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).
LAN (local area network). Any physical network technology that operates at high speed
(usually tens of megabits per second through several gigabits per second) over short
distances (up to a few thousand meters).
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.
LAPB (Link Access Protocol —Balanced). ITU-T standards that define in the Data Link
Layer the requirements for X.25 connections over wide area networks (WANs).
