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.
