CIR
The Local-to-Remote CIR and Remote-to-Local CIR represent the
Committed Information Rate of the Ethernet Service under test:
1.0 Mbit/s to Line Rate. The CIR is not used to actually transmit frames
at this rate but to calculate a Bandwidth Delay Product (BDP) which in
turn is used to set the Max Window Size of the TCP connections.
Rate Unit determines the unit used to display the rate values:
Mbit/s (default) or Gbit/s.
TOS/DS (IPv4) allows to enter an hexadecimal value, 00 (default) to
FF. Changing the IP TOS/DS value will affect the TOS/DS Config
settings and vice versa.
MTU
Max MTU (bytes) determines the Maximum Transfer Unit (MTU) to
use when the client is generating TCP traffic toward the server: from
1080 to 1500 bytes (default).
Path MTU Discovery check box when selected (default) allows to
perform a Packetization Layer Path MTU Discovery phase.
Window Sweep
Window Sweep check box when selected (default) allows to perform
the Window Sweep phase.
Duration (per step) is the duration of the Window Sweep phase per
direction and per Window tested: 30 seconds (default) to 5 minutes.
