QUIC works hand-in-hand with HTTP/3’s multiplexed connections, allowing multiple streams of data to reach all the endpoints independently, and hence independent of packet losses involving other streams. In contrast, HTTP/2, which is carried over TCP, can suffer head-of-line-blocking delays if multiple streams are multiplexed on a TCP connection and any of the TCP packets on that connection are delayed or lost.
SCTP was going to do that too. It hasn’t seen much uptake.

Features of SCTP include:
- Delivery of chunks within independent streams eliminates unnecessary head-of-line blocking, as opposed to TCP byte-stream delivery.



















An article I was reading (on marine cable cutting, unrelated topic) mentioned a clause in marine insurance policies.

It might be that whether-or-not the US is involved determines whether shipowners or insurers are on the hook for a ship getting shot at.
Though…reading it over, maybe it’s only if it’s specifically one of those fighting another of them.
