The lone neurone strikes again:

A typical network use pattern is:

  - connect
  - begin download

So link reservation windows where the pertinent parameter is time T,
may be complemented with "data xmit" total, either at link setup,
and/ or "shortly" after link has been set up.

So this protocol might be e.g.

  - connect, default time reservation e.g. 2 minutes
  - begin download
  - (e.g. HTTP) headers identify the download as being say 160MiB
  - link/switch request to modify "T=2 minutes" to "xmit=170MiB"
  - ack or nack from peer nodes as they are willing/able
