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
