Major activity token. One of the four types of Session Layer tokens that are associated
with functional units. See Token and Functional unit.
Major synchronization. In the Session Layer, the separation of the exchange of data into a
series of dialog units. A major synchronization point indicates the end of one dialog
unit and the beginning of the next. Each major synchronization point is confirmed
explicitly. Compare minor synchronization.
Management application. In DSM, an application process that opens a management or
subsystem process to control a subsystem. This process can issue SPI commands to
subsystems and retrieve EMS event messages to assist in managing a computer system
or a network of systems. A management application is a requester with respect to the
subsystems to which it sends commands; the subsystems are servers with respect to
the management application.
Management process. In DSM, a Tandem process through which an application issues
commands to a subsystem. A management process can be part of a subsystem, or it
can be associated with more than one subsystem; in the latter case, the management
process is logically part of each of the subsystems. SCP is the management process for
all Tandem data communications subsystems that support DSM. See also subsystem.
Manager process. In DSM, a Tandem subsystem process with which the SCP
management process communicates to control a particular data communications
subsystem. The OSI manager process and TAPS process are both manager processes
for OSI/AS; the TSP process is the manager process for OSI/TS.
MIB (Management Information Base). A database used by the OSI manager process to store
and retrieve configuration information and information about applications. The MIB
consists of the LDIB and the LMIB. The LDIB (Local Directory Information Base) is the
part of the MIB that contains local subsystem addressing information about
applications. The LMIB (Local Management Information Base) is the part of the MIB
that contains local subsystem configuration and management information.
Minor synchronization. In the Session Layer, the structuring of the exchange of data
within a dialog unit. Each minor synchronization point may or may not be confirmed
explicitly. Compare major synchronization.
MLAM (Multilan access method). The I/O process that is part of the Tandem TLAM
product. See TLAM.
Multiplexing. See address sharing, connection multiplexing or passive multiplexing.
Network address. See NSAP and NSAP address.
Network addressing administrator. The person who implements the addressing rules
specified by a network addressing authority.
Network Layer. Layer 3 in the OSI Reference Model. This layer routes data by
establishing, maintaining, and terminating communications between nodes. It sets up
the most economical path, both physical and logical, between communicating nodes;
routes messages through intervening nodes to their destinations; and controls the flow
of messages between nodes.
