Interaction between Routing and Reservation

• Delay between advertisement and resource reservation

• Interface between RSVP and QoSR

• Route_Query (with Tspec) to routing module

• Route_Response to RSVP

• Explicit_Route opaque object carried in PATH messages

• Routing module simply returns next-hop on explicit route in response to Route_Query from RSVP

• Path pinned for the duration of the flow (pinned flag set in PATH messages)

• PATH refreshes follow pinned next-hops
