A method, by a control node (100, 150), for selecting one of a plurality of media forwarding elements (200, 250) in a network for forwarding an additional media data stream by the selected media forwarding element, the method comprising the steps of: - receiving (S21, S31, S100) a load message from one of the media forwarding elements, the load message containing information about a load level of said one media forwarding element and about how media data streams from a first area of the network from which said one media forwarding element receives the media data streams contribute to the load level of said one media forwarding element, - storing the received information in a storage unit of the control node, - receiving (S22, S35) a setup request for an additional media data stream, the setup request requesting a selection of one of the media forwarding elements for the additional media data stream by the control node (100, 150), - selecting one of the media forwarding elements for the additional media data stream taking into account the stored information, wherein, for the selection, it is checked based on the stored information whether the setup request for the additional media data stream is relating to a media data stream from the first area, wherein, if the additional media data stream is relating to a media data stream from the first area, said one media forwarding element is excluded (S23, S105) from the selection of the media forwarding element for the additional media data stream, wherein the selection of said one media forwarding element is allowed for the additional media data stream when the setup request is relating to a media data stream from a second area of the network that is different to the first area - transmitting a reject message (S52, S62) to a flow control entity which controls the media data streams transmitted to said one forwarding element from the first area, the reject message instructing the flow control entity to reject further setup requests for further media data streams which would result in a further media data stream to said one media forwarding element from the first area to the area controlled by the control node (100,150). - receiving (S21, S31, S100) a load message from one of the media forwarding elements, the load message containing information about a load level of said one media forwarding element and about how media data streams from a first area of the network from which said one media forwarding element receives the media data streams contribute to the load level of said one media forwarding element, - storing the received information in a storage unit of the control node, - receiving (S22, S35) a setup request for an additional media data stream, the setup request requesting a selection of one of the media forwarding elements for the additional media data stream by the control node (100, 150), - selecting one of the media forwarding elements for the additional media data stream taking into account the stored information, wherein, for the selection, it is checked based on the stored information whether the setup request for the additional media data stream is relating to a media data stream from the first area, wherein, if the additional media data stream is relating to a media data stream from the first area, said one media forwarding element is excluded (S23, S105) from the selection of the media forwarding element for the additional media data stream, wherein the selection of said one media forwarding element is allowed for the additional media data stream when the setup request is relating to a media data stream from a second area of the network that is different to the first area - transmitting a reject message (S52, S62) to a flow control entity which controls the media data streams transmitted to said one forwarding element from the first area, the reject message instructing the flow control entity to reject further setup requests for further media data streams which would result in a further media data stream to said one media forwarding element from the first area to the area controlled by the control node (100,150).
