RSVP (4)
RSVP Tunnel
- connects RSVP-capable routers through a cloud of non-RSVP routers
- RSVP is not implemented in all routers
- condition non-RSVP network must provide acceptable and sufficient capacity and real-time service
RSVP soft state implementation
- soft state refers to a state in routers and end nodes that can be updated dynamically by certain RSVP messages
- when state changes occur RSVP propagates those changes from end to end within RSVP network without delay
