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.
