multicast
multicast. A technique that allows copies of a single packet to be passed to a selected subset
of all possible destinations. Some hardware (for example, Ethernet) supports multicast
by allowing a network interface to belong to one or more multicast groups. Broadcast is
a special form of multicast in which the subset of machines selected to receive a copy of
a packet consists of the entire set.
multifunction I/O board (MFIOB). A ServerNet adapter that contains ServerNet
addressable controllers (SACs) for SCSI and Ethernet; a service processor; ServerNet
links to the processor, to the two ServerNet adapter slots, and to one of the ServerNet
expansion board (SEB) slots; and provides connections to the serial maintenance bus
(SMB), which connects components within an enclosure to the service processor.
MULTILAN. A hardware and software product that allows users to connect their local area
networks (LANs) to Compaq NonStop systems.
MULTILAN 6530 WINDOW. The 6530 WINDOW API provides NetBIOS-compatible
communications between a Compaq host-based application and a workstation-based
6530 terminal emulator, such as PCT or Outside View.
MULTILAN Access Method (MLAM). The I/O process that is part of the Compaq TLAM
product. See TLAM
.
MULTILAN Attachment Device (MLAD). A unit that provides the interface for adapter
cards through the MULTILAN controller in order to communicate with workstations
over the network.
MULTILAN File Server (MLSRV). A server program on a Compaq system that is used to
maintain DOS files on disk. MLSRV also provides workstation access to the NonStop
Kernel File System and Spooler.
MULTILAN Resource Manager (MLRM). The MULTILAN Resource Manager provides
security and dynamic configuration services for workstation sessions.
MULTILAN WSPTP. The Workstation Process-To-Process API provides NetBIOS-
compatible communications between Compaq host-based applications and workstation-
based applications.
NetBIOS. See Network Basic I/O System (NetBIOS).
Network Basic I/O System (NetBIOS). An interface between programs executing in the
workstation and an attached LAN.
NFS (Network File System). A protocol developed by SUN Microsystems that uses IP to
allow a set of cooperating computers to access each other's file systems as if they were
local. The key advantage of NFS over conventional file transfer protocols is that NFS
hides the differences between local and remote files by placing them in the same name
space. NFS is used primarily on UNIX systems, but has been implemented for many
systems, including personal computers like an IBM PC and Apple Macintosh.
