This comment illustrates an advantage for using RTP MIDI
to send MIDI over lossy networks. The recovery journal in
RTP MIDI supports graceful recovery from the loss of an arbitrary
number of packets upon the receipt of the first packet after the
loss (also works for reordering). Journalling is a feed-forward
no retransmission is used -- thus, no head-of-line-blocking latency
issues as one has when running media over TCP.
The IESG approved RTP MIDI in February, so the protocol is
frozen. Hopefully the copy-edit phase will be done by autumn
and then we'll have RFC numbers for RTP MIDI.
