Foil 3 RSVP Protocol Mechanisms

From Part II of RSVP Reservation Protocol CPS640 Internet and Multimedia Technologies -- Spring 98. by Marek Podgorny,Nancy McCracken
RSVP Messages
  • Two basic RSVP message types: Resv and Path.
    • Each RSVP sender host transmits RSVP Path messages downstream along the uni-/multicast routes provided by the routing protocol(s), following the paths of the data.
    • Path messages store "path state" in each node along the way. This path state includes at least the unicast IP address of the previous hop node, which is used to route the Resv messages hop-by-hop in the reverse direction.
