2- Renegotiation
- Static descriptors don’t make sense for interactive sources
- Multiple-time-scale traffic
- burst size B that lasts for time T
- for zero loss, descriptors (P,0), (A, B)
- P = peak rate, A = average
- T large => serving even slightly below P leads either to large buffering requirements or large loss rate
- one-shot descriptor is inadequate
- Renegotiation matches service rate to traffic
- Renegotiation is not free- signaling overhead
