QoS
Quality of Server, a characteristic of data transmission that measures how accurately
and how quickly a message or data is transferred from a source host to a destination
host over a network. The four QoS options are:
−
UBR (Unspecified Bit Rate): When UBR is selected, the SCR and
MBS fields are disabled.
−
CBR (Constant Bit Rate): When CBR is selected, the SCR and MBS
fields are disabled.
−
nrt-VBR (non-real-time Variable Bit Rate): When nrt-VBR is
selected, the SCR and MBS fields are enabled.
−
rt-VBR (real-time Variable Bit Rate): When rt-VBR is selected, the
SCR and MBS fields are enabled.
PCR
Peak Cell Rate, measured in cells/sec., is the cell rate which the source may never
exceed.
SCR
Sustained Cell Rate, measured in cells/sec., is the average cell rate over the
duration of the connection.
MBS
Maximum Burst Size, a traffic parameter that specifies the maximum number of cells
that can be transmitted at the peak cell rate.
