Issues

• What kind of user and network are we talking
  about?
• Is this end-to-end, network-to-network, or UNI?
• Why admission control? What about
  over-provisioning?
• Where to apply admission control and resource
  reservation?
• What about backbone and inter-domain?
• Lightweight vs. inter-domain?
• What about security and DoS attacks?
• Why/how lightweight?
• scaling for both existing and future machines
• Can we use the existing RSVPv1 ?
• Its working, deployed and per-flow
• Soft-state, multicast, shared reservation,
  receiver-initiated reservation, two-pass
  reservation and the applications.
• What to do from here?
