As per RFC 2889, if there is Frame loss Error Rate, the throughput wouldn't be calculated. Throughput would be calculated only when there is zero frame loss rate
Section 5.1.4.1 Throughput Throughput measurement is defined in section 26.1 [3]. A search algorithm is employed to find the maximum Oload [2] with a zero Frame loss rate [1]. The algorithm MUST adjust load to find the throughput.
