You just described TCP

[hpx7]

It's close but TCP will retransmit frames rather than packing multiple updates in a single frame.

It's common for people to build this kind of retransmission logic on top of UDP (especially for networked games), it's sometimes referred to as "reliable UDP".

It’s not TCP, it’s TCP without head-of-line blocking, which makes it much more suitable for real time games.

[vvanders]

TCP forces sequencing across all packets, SCTP is a bit closer.
