Yeah.  I understand the problem that TCP is trying to solve.<p>My thinking was that there is a whole class of network applications that don&#x27;t work great under TCP because the retransmission mechanism drives latency super high when congestion is experienced in the network.  TCP works to back off transmission that might be the cause of packet loss, but those packets still have to be transmitted again and the bandwidth timeslot consumed by the dropped packet amounts to wasted resources in the network.  In a datacenter microburst situation, retransmissions just tickle the problem you&#x27;re trying to avoid.<p>FEC over a lossy network would allow for a slight increase in the baseline resource utilization with the side benefit of eliminating retransmissions which might be beneficial in a microburst environment.  I don&#x27;t really know, I&#x27;m just thinking aloud.
