<p num="1"><br/><br/><br/>A Resource Manager node and methods for establishing and modifying an inter-<br/>domain QoS reservation between a first node in a first domain and a further <br/>node in a further domain. After detection that the QoS reservation with at <br/>least one QoS characteristic is needed or needs to be refreshed, obtaining, at <br/>the first node, network state information associated to at least one possible <br/>choice of path between the first domain and the further domain. Thereafter, <br/>determining at least one choice of path between the first domain and the <br/>second domain in view of the at least one QoS characteristic, selecting a <br/>selected path to support the QoS reservation and sending a reservation message <br/>to trigger establishment of the inter-domain QoS reservation.<br/>
