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.
Claims6
A router in a first administrative domain of a telecommunications network, the first administrative domain comprising a first end point having a first address, the first end point being associated to a reservation for a session transiting through the router between the first end point and a second end point in a second administrative domain, the router comprising a quality of service (QoS) reservation module, the QoS reservation module being capable of:
- receiving an address modification notification related to the reservation from the first end point through a first access router, wherein the address modification notification indicates that the first end point changes its first address for a second address since the first end point is changing from the first access router to a second access router;
- and
- issuing a first reservation message on behalf of the second end point toward the second access router.
A method of 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 comprising 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.
An end point having a first address in a first administrative domain of a telecommunications network, the first administrative domain comprising a first access router and a domain router, the end point being associated to a reservation for a session transiting through the first access router and the domain router toward a second end point in a second administrative domain, the end point router comprising a quality of service (QoS) reservation module, the QoS reservation module being capable of:
- upon detection of a need for a change from the first access router to a second access router:
- issuing an address modification notification related to the reservation toward the domain router, wherein the address modification notification indicates that the end point changes its first address for a second address since the end point is changing from the first access router to a second access router.
