RSVP
RSVP has the following attributes:
- RSVP makes resource reservations for both unicast and many-to-many multicast applications, adapting dynamically to changing group membership as well as to changing routes
- RSVP is simplex, i.e., it makes reservations for unidirectional data flows
- RSVP is receiver-oriented, i.e., the receiver of a data flow initiates and maintains the resource reservation used for that data flow
- RSVP maintains "soft" state in routers and hosts, providing graceful support for dynamic membership changes and automatic adaptation to routing changes
- RSVP is not a routing protocol but depends upon present and future routing protocols
