Segment In ethernet networks, a section of a network that is bounded by
bridges, routers or switches. Dividing a LAN segment into multiple
smaller segments is one of the most common ways of increasing
available bandwidth on the LAN.
SLP Service Location Protocol. A method of organizing and locating the
resources (such as printers, disk drives, databases, e-mail directories,
and schedulers) in a network. Using SLP, networking applications can
discover the existence, location and configuration of networked
devices.
With Service Location Protocol, client applications are 'User Agents'
and services are advertised by 'Service Agents'. The User Agent issues
a multicast 'Service Request' (SrvRqst) on behalf of the client
application, specifying the services required. The User Agent will
receive a Service Reply (SrvRply) specifying the location of all services
in the network which satisfy the request.
For larger networks, a third entity, called a 'Directory Agent', receives
registrations from all available Service Agents. A User Agent sends a
unicast request for services to a Directory Agent (if there is one) rather
than to a Service Agent.

SMI Structure of Management Information. A hierarchical tree structure for
information that underlies Management Information Bases (MIBs), and
is used by the SNMP protocol. Defined in RFC1155 and RFC1442
(SNMPv2).
SMT (802.11) Station ManagemenT. The object class in the 802.11 MIB that provides
the necessary support at the station to manage the processes in the
station such that the station may work cooperatively as a part of an
IEEE 802.11 network. The four branches of the 802.11 MIB are:
● dot11smt - objects related to station management and local
configuration
● dot11mac - objects that report/configure on the status of various
MAC parameters
● dot11res - Objects that describe available resources
● dot11phy - Objects that report on various physical items.
SNMP Simple Network Management Protocol. A set of protocols for
managing complex networks. SNMP works by sending messages,
called protocol data units (PDUs), to different parts of a network.
SNMP-compliant devices, called agents, store data about themselves
in Management Information Bases (MIBs) and return this data to the
SNMP requesters.
SNMP includes a limited set of management commands and
responses. The management system issues Get, GetNext and Set
messages to retrieve single or multiple object variables or to establish
the value of a single variable. The managed agent sends a Response
message to complete the Get, GetNext or Set.
