Which mechanism maximize “Goodput?”
A.
Payload Type Identifier – PTI
B.
Partial Packet Discard – PPD
C.
Constant Bit Rate – CBR
D.
Statistical Packet Discard – SPD
E.
Early Packet Discard – EPD
Explanation:
A more performant mechanism can be implemented with early packet discard (EPD). In this case, upon reaching a certain congestion threshold, a switch starts dropping complete PDUs, including the first, all intermediate cells, andthe last cell, avoiding less efficient partial drops.
