RSVP - Resource Reservation Protocol
enables Internet applications to obtain special QoS
it is not a routing protocol, but it works in conjunction with routing protocols
RSVP is a Transport Protocol in OSI RM ( 4th layer)
RSVP supports 3 types of traffic
  • best-effort: traditional IP traffic (best effort service)
  • rate-sensitive: e.g. H323 video-conferencing require constant transport rate (guaranteed bit-rate service)
  • delay sensitive: e.g. MPEG-II (predictive service or controlled-delay service)
