List of terms
trace destination interface
The interface on which a path or connection trace terminates when it completes normally.
trace destination node
The node that terminates the path or connection trace for a given connection and has an outgoing trace destination interface.
trace source interface
The interface at the trace source node that is designated as the starting point for the path or connection trace of a given connection.
trace source node
The node that initiates the path or connection trace for a given connection.
trace transit list (TTL) information element
An identifier added to the signaling messages to collect trace information.
traffic contract
The agreement that specifies the required transfer characteristics for an ATM connection.
traffic descriptor parameter (TDP)
There are five parameters that are used to define a traffic descriptor type (TDT). Taken together with the QOS, these parameters specify the traffic characteristics of an ATM connection.
The five values used in the traffic descriptor parameters are peak cell rate (PCR), sustainable cell rate (SCR), maximum burst size (MBS), cell delay variation tolerance (CDVT), and requested shaping rate (RSR).
traffic descriptor type (TDT)
Traffic descriptor types define which traffic descriptor parameters are applied to a connection. Types are defined in the ATM Forum 3.0/3.1 and 4.0 standards. Nortel Multiservice Switch system also incorporates proprietary parameters that are used in traffic shaping, CAC, and UPC.
traffic management (TM)
A set of mechanisms in hardware and software that enhance the availability of bandwidth to connections that absolutely require it and prevent the overloading of networks to prevent data losses.
traffic shaping
A method used to smooth out traffic bursts by regulating the emission interval of cells or frames in the transmit direction. This is useful for ensuring conformance of transmitted traffic to subscribed traffic parameters.
