QoS
Quality of Service, 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.
