Trail
An entity that transfers information provided by a client layer network between
access points in a server layer network. The transported information is monitored
at the termination points.
Trailer
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 second designated boundary.
Trap
A function performed by switch software to catch or trap errors, changes, failures,
or problems with the switch software or hardware. The trap information is sent to
a network management station.
Trm
An ABR service parameter that provides an upper bound on the time between
forward RM-cells for an active source. It is 100 times a power of two with a range
of 100*2-7 to 100*20
TS
Transport Stream: One of two types of streams produced by the MPEG-2 Systems
layer. The Transport Stream consists of 188 byte packets and can contain multiple
programs.
TS
Traffic Shaping: Traffic shaping is a mechanism that alters the traffic characteristics
of a stream of cells on a connection to achieve better network efficiency, while
meeting the QoS objectives, or to ensure conformance at a subsequent interface.
Traffic shaping must maintain cell sequence integrity on a connection. Shaping
modifies traffic characteristics of a cell flow with the consequence of increasing the
mean Cell Transfer Delay.
TS
Time Stamp: Time Stamping is used on OAM cells to compare time of entry of cell
to time of exit of cell to be used to determine the cell transfer delay of the
connection.
