ABSTRACT:
A method, an associated end point and an associated router for updating a reservation established for a session between a first end point in a first administrative domain and a second end point in a second administrative domain wherein the reservation is valid in the first administrative domain between the first end point, an access router and a domain router. The method comprises the steps of detecting that the first end point connected to the access router needs to change toward a second access router, in the domain router, receiving an address modification notification related to the reservation from the first end point and issuing a first reservation message from the domain router on behalf of the second end point toward the second access router.
