INTER-DOMAIN QOS RESERVATION ESTABLISHMENT AND MODIFICATION

摘要

A Resource Manager node and methods for establishing and modifying an inter-domain QoS reservation between a first node in a first domain and a further node in a further domain. After detection that the QoS reservation with at least one QoS characteristic is needed or needs to be refreshed, obtaining, at the first node, network state information associated to at least one possible choice of path between the first domain and the further domain. Thereafter, determining at least one choice of path between the first domain and the second domain in view of the at least one QoS characteristic, selecting a selected path to support the QoS reservation and sending a reservation message to trigger establishment of the inter-domain QoS reservation.
