8: RFC-2544
RFC-2544 testsuite
123
Type
Layer-2 or Layer-3.
Layer-2 settings
Port name
Name configured for the port on which to send the flow(s).
MAC destination
This is the peer MAC address.
Layer-3 settings
Destination IP address
The IP address of the remote side.
DSCP
The DiffServ Code Point to set in the generated packets.
UDP port settings (Source & Destination)
Specify the UDP port numbers used to generate the UDP packet.
Y.1731 MEG level
The Maintenance Entity Group level.
VLAN ID
VLAN identifier, possible values are 0 to 4095. Applies only when the specific VLAN is
enabled.
VLAN priority
VLAN priority bits, possible values are 0 to 7. Applies only when the specific VLAN is enabled.
VLAN CFI
Specify the Canonical Format Indicator. This should always be set to zero for connections to
Ethernet switches. Applies only when the specific VLAN is enabled.
Throughput settings
These settings are used to define the Throughput test, which searches for the maximum rate
for which there is no frame loss. The Trial duration parameter defines the length during which
throughput will be analyzed and during which no frame loss shall occur. The Maximum rate
and Minimum rate define the range of rates to search for while the Step size defines the
granularity of the range. For example, if the user wishes to measure the quality of a wirespeed
GigE circuit, he would enter a range of 800 Mbps and 1000 Mbps with a step size of 10 Mbps.
The NID would then test at full GigE speed, 1000 Mbps and perform a dichotomist algorithm
between 800 and 1000 (and a granularity of 10) to find the highest rate for which there is no
frame loss. The frame loss setting defines the acceptable difference between measured frame
loss. For example, a setting of 1 would mean a 0.1% frame loss would be acceptable and
considered as no frame loss by the test. The default value is 0, which means absolutely no
frame loss is the target for defining full throughput. The Frame Size parameters let the user
choose which frame sizes are to be tested. By default, the 10000 byte frame size (Jumbo
frame) is unselected as it was not a frame size defined by the RFC-2544 standard, but which
Accedian supports nevertheless.
