Requirements: Motivation and Issues (cont.)
Unicast transport
- Why: majority of traffic in these networks is currently unicast;
- Issues: What are the multicast parts of the signalling that can be modularized so that we can choose not to use it?
Scalably manageable
- Why: many protocols are defined without taking their management into consideration;
- Issue: who’s going to work on the management of this infrastructure and what’s required (MIBs? PIBs? XML-based?)
-
Bi-directional reservations
- Why: in some networks there are nodes that initiate bi-directional reservations;
- Issue: is this a core requirement or an optional part of the “toolkit”?
