Service
Performance Test
Use the check boxes to specify which directions to test.
Line
Use the drop-down menu to select how the service attributes for the
directions are set up.
Symmetrical: The same service attributes are used for both directions.
Asymmetrical: Service attributes are set up for each direction.
Test Sync. Mode
Use the drop-down menu to select the method for synchronization of the two
instruments performing the test. Synchronization is required for correct
measurement of FTD and FDV in End to End Test mode.
Select GPS if external GPS receivers are available at both the local and
the remote site. This gives the most accurate measurements.
Select Pre-test sync. if GPS is not available for both instruments. In this
mode, synchronization is obtained using proprietary protocol prior to the
first step of the Service Configuration Test.
External GPS sensor is available from Anritsu (part no. G0325A).
Use local SRC as DST on remote side
Select this to transfer the local source IP address to the remote side, to be
used as destination IP address. If ARP is enabled locally, it will also be
enabled on the remote side. If IP is disabled, the local source MAC address
will be transfered to the remote side, to be used as destination MAC address.
The CIR/EIR rates for services refer to either information rate or utilized line
rate. Use the radio buttons to specify which bit realm to operate in.
Information rate
The bit rate of frames starting with the first MAC address bit and ending with
the last FCS bit.
In this realm actual load on the Ethernet line is bigger as minimum inter
frame gap, preamble, and start of frame delimiter (20 octets in total per
frame) are not included. Maximum possible value depends on selected
framesize(s).
For instance, a 100 Mbit/s Ethernet port can handle a total information rate of
about 77 Mbit/s to 99 Mbit/s depending on the average frame size of the
transmitted Ethernet frames.
Utilized line rate
The bit rate of the Ethernet line, including the bits for:
The minimum inter frame gap
Preamble
Start of frame delimiter
Frame starting with the first MAC address bit and ending with the last FCS
bit.
In this realm the Ethernet line rate defines the maximum combined CIR rate
for all included services.
Complete despite SAC violation
Select this check box to allow the configuration test to be completed despite
any detected SAC violations. If not selected, the configuration test will stop
when the first SAC violation is detected.
Duration
Allows you to set the duration period of the performance test. Either select
one of the predefined values in the drop-down menu or use the field to
specify a custom period.
