I have been saying that DTN is a reinvention of UUNET.

Hmmm, nope not even close.

As such, it should be noted that, in UUNET, availability of
phone links between computers was scheduled.

You must be talking about UCCP, UUNET was a company.

Availability of links was declared not scheduled, so pathalias was able to figure the best UUCP path from a given UUCP node.
