Suppose someone proposes TCP over multicast, in which each router collects the ACKs returning from the group members reached through it, and consolidates them into a single ACK. This now means that, like the multicast traffic itself, no ACK is duplicated on any single link.

What problems do you foresee with this proposal? (Hint: who will send retransmissions? How long will packets need to be buffered for potential retransmission?)
