MPA gets MPA Reply Frame, passes “private data” to consumer, Consumer binds MPA to DDP, MPA and DDP go into full operation.

MPA sends “MPA Request Frame” with “private data” and waits for the “MPA Reply Frame” Responder MPA gets MPA Request Frame, passes “private data” to consumer, Consumer binds MPA to DDP, MPA sends MPA Reply Frame, FPDU decoding enabled. MPA gets first FPDU; Goes into Full iWARP mode. First iWARP message sent by RNIC (When WQE is posted) TCP gets SYN Sends SYN-Ack TCP gets SYN-Ack Sends Ack Note Note: The Ack may be in the same segment as the MPA Request Frame in some implementations! |
