  2. What is this draft about? • The NSIS working group has selected two applications: • QoS signaling • NAT/Firewall signaling • Path-coupled signaling is useful for other application areas as well. • Goal: Dynamically configure and coordinate accounting entities rather than hardwiring them • This draft discusses the usage of NSIS in two scenarios: • Charging • Monitoring

  6. Next Steps • Does the working group think that this is interesting? • How to proceed with new NSLPs such as this one? • Comments are appreciated?
