- 17. The method of claim 16 wherein the steps of receiving and sending are performed by a home agent.
- 18. The method of claim 16 wherein the steps of receiving and sending are performed by the mobile node.
- 19. The method of claim 16 operating according to mobile IP version 4.
- 20. The method of claim 16 operating according to mobile IP version 6.
- 21. The method of claim 19 operating according to RSVP.
- 22. The method of claim 20 operating according to RSVP.

- 24. The method of claim 22 wherein the path message comprises an RSVP PATH message and the reservation request message comprises an RSVP RESV message.
- 25. A route-optimization method comprising the steps of:
receiving a binding request; sending a binding update in response to the binding request, wherein the binding update includes a care-of address of a mobile node; receiving a path message sent in response to receipt of the binding update, wherein the path message explicitly binds a data path of a packet flow to the mobile node; and sending a reservation request message responsive to the path message.
- 26. The method of claim 25 wherein the steps of receiving the binding request, sending the binding update, receiving the path message, and sending the reservation request message are performed by the mobile node.
- 27. The method of claim 25 wherein the steps of receiving the binding request and sending the binding update are performed by a home age and nd the steps of receiving the path message and sending the reservation request message are performed by the mobile node.
- 28. The method of claim 25 operating according to mobile IP version 4.
- 29. The method of claim 25 operating according to mobile IP version 6.
- 30. The method of claim 28 operating according to RSVP.
