I'm just curious, do we have any information on how the designers of this system feel about frame sizes? Like, are they big frame people or small frame people? That could really sway the answer, you know?

Hold up, what if the protocol is designed to automatically adjust the throughput to compensate for the larger frame size? In that case, the throughput could stay the same. Option C might be the right answer here.

Yeah, that makes sense. The protocol could handle the adjustment.

I think the throughput might stay the same if the protocol adjusts for the larger frame size.

Hmm, I'm not so sure. If the frame size doubles, the buffer credits might need to be adjusted to maintain the maximum throughput. Option D looks like the way to go.
