Glossary
topology -
a program that displays the topology of a FORE Systems ATM network. An
updated topology can be periodically re-displayed by use of the interval command option.
Traffic -
the calls being sent and received over a communications network. Also, the packets
that are sent on a data network.
Traffic Management (TM) -
The traffic control and congestion control procedures for ATM. ATM
layer traffic control refers to the set of actions taken by the network to avoid congestion condi-
tions. ATM layer congestion control refers to the set of actions taken by the network to mini-
mize the intensity, spread and duration of congestion. The following functions form a
framework for managing and controlling traffic and congestion in ATM networks and may be
used in appropriate combinations:
Connection Admission Control
Feedback Control
Usage Parameter Control
Priority Control
Traffic Shaping
Network Resource Management
Frame Discard
ABR Flow Control
Traffic Parameter -
A parameter for specifying a particular traffic aspect of a connection.
Trailer -
the protocol control information located at the end of a PDU.
Transit Delay -
the time difference between the instant at which the first bit of a PDU crosses
one designated boundary, and the instant at which the last bit of the same PDU crosses a sec-
ond designated boundary.
Transmission Control Protocol (TCP) -
a specification for software that bundles and unbundles
sent and received data into packets, manages the transmission of packets on a network, and
checks for errors.
Transmission Control Protocol/Internet Protocol (TCP/IP) -
a set of communications protocols
that has evolved since the late 1970s, when it was first developed by the Department of
Defense. Because programs supporting these protocols are available on so many different
computer systems, they have become an excellent way to connect different types of computers
over networks.
Transmission Convergence (TC) -
generates and receives transmission frames and is responsi-
ble for all overhead associated with the transmission frame. The TC sublayer packages cells
into the transmission frame.
Transmission Convergence Sublayer (TCS) -
This is part of the ATM physical layer that defines
how cells will be transmitted by the actual physical layer.
Transparent Asynchronous Transmitter/Receiver Interface (TAXI) -
Encoding scheme used for
FDDI LANs as well as for ATM; supports speed typical of 100 Mbps over multimode fiber.
