Frame Loss Rate Analysis
Frame Loss Rate Analysis
Note: An analysis of frame loss rate is necessary for checking the network's
capability to support real-time applications (which do not provide for
retransmission), as a high frame loss rate causes the deterioration of QoS.
An analysis of frame loss rate allows calculating the percentage of frames
that a network element has failed to transmit in case of steady load due to
the shortage of hardware resources.
During an analysis of frame loss rate, a number of frames are sent to the
input of DUT at a certain rate (input count) and the quantity of packets
which have been received from the output port of DUT (output count) is
calculated.
Frame loss rate is calculated according to the following formula:
100 x (inputcount — outputcount)
(inputcount)
The first attempt should be made at the maximum data rate for this
connection. The next attempt should be made at the rate which equals 90.
