ATM QoS
ATM QoS Type
Select
CBR
(Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data
traffic. Select
UBR
(Unspecified Bit Rate) for applications that are non-time sensitive,
such as e-mail. Select
nrtVBR
(Variable Bit Rate-non Real Time) or
rtVBR
(Variable Bit
Rate-Real Time) for bursty traffic and bandwidth sharing with other applications.
Peak Cell Rate
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell Rate
(PCR). This is the maximum rate at which the sender can send cells. Type the PCR here.
Sustain Cell Rate
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted. Type the SCR, which must be less than the PCR. Note that system default is
0 cells/sec.
Maximum Burst
Size
Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent at
the peak rate. Type the MBS, which is less than 65535.
MTU
MTU
The Maximum Transmission Unit (MTU) defines the size of the largest packet allowed on
an interface or connection. Enter the MTU in this field.
For ENET ENCAP, the MTU value is 1500.
For PPPoE, the MTU value is 1492.
For PPPoA and RFC, the MTU is 100-1500.
