service rating
A value assigned to a
network resource
by the service node to indicate its relative
capability to accept new sessions. The rating is scaled from 0 to 255, where 255 is the
greatest capacity. Access servers use this rating to choose a service node when a user
attempts to connect to a service that is offered by multiple service nodes.
service session
A
session
between a
network resource
and a
terminal session
on a
session management
terminal.
session
A two-way network communications path between a
network resource
and either a
access server user, a multiuser computer user, or an application program.
session management
A facility provided by some access servers that uses
TD/SMP
to communicate with a
access server device so that the device can process simultaneous, independent,
multiple
terminal sessions
. On the device, the data exchange of multiple sessions can
be processed simultaneously regardless of which session is current.

SLIP
Serial Line Internet Protocol

transmit
IP datagrams
over serial lines.
SLIP host
An
Internet host
that uses
SLIP
as its data link.
SNMP
Simple Network Management Protocol
. An Internet protocol that is used to manage
systems from one or more Internet hosts.
subnet addressing
An addressing technique that allows a site to share a single Internet network address
among multiple logical networks, as long as all the hosts and gateways on those
networks cooperate. It is a form of hierarchical routing in which the top level of the
routing hierarchy, the core gateway system, uses the network portion of the Internet
address (when routing packets) to identify the local gateway. The next level, the local
gateway, uses part of the host portion of the Internet address to identify the subnet and
route packets to it. And finally, the lowest level, the specific host computer, uses the
remainder of the host portion of the address to identify and accept packets addressed
to it.
