"nconnect" is a Linux client facility. Do you mean the Linux scheduling
behavior specifically, or scheduling I/O in general on multiple
connections?

My feeling (fwiw) is it is a bit late to add a topic like this for IETF
116, and the agenda is already pretty full. Could you take this to the
WG mailing list first (or to a Linux-specific list) or even better,
write a problem statement as a personal draft?
