Selective steering of media data streams
First Claim
1. A method, by a control node, for selecting one of a plurality of media forwarding elements in a network for forwarding an additional media data stream by the selected media forwarding element, the method comprising the steps of:
- receiving 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 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;
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 set up 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 from the selection of the media forwarding element for the additional media data stream.

Abstract
The invention relates to 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 (300) 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. The received information is stored in a storage unit (130) of the control node. When a setup request for an additional media data stream is received, the setup request requesting a selection of one of the media forwarding elements for the second media data stream by the control node (100, 150). One of the media forwarding elements is selected 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 set up request for the additional media data stream is relating to a media data stream from the first area (300), wherein, if the second media data stream is relating to a media data stream from the first area (300), said one media forwarding element is excluded (S23, S105) from the selection of the media forwarding element for the additional media data stream.

8. A method, by a media forwarding element, for forwarding an additional media data stream through a network, the method comprising the steps of:
-
identifying at least a first area of the network from which media data streams are received; identifying a load level of the media forwarding element; identifying how the media data streams from the first area contribute to the load level of the media forwarding element; and transmitting a load message to a control node which selects the media forwarding elements for the different media data streams in the network, wherein the load message contains the information about the load level of the media forwarding element and about how the media data streams from the first area of the network contribute to the load level of the media forwarding element. - View Dependent Claims (9)

10. A control node configured to select one of a plurality of media forwarding elements in a network for forwarding an additional media data stream by the selected media forwarding element, the control node comprising:
-
a receiver configured to receive 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, the receiver being further configured to receive a setup request for an additional media data stream, the set up request requesting a selection of one of the media forwarding elements for the additional media data stream by the control node; a storage unit configured to store the received information; and processing circuitry operative as a forwarding element selecting module configured to select the media forwarding elements for different media data streams in the network; wherein, when the receiver receives the set up request for the additional media data stream, the forwarding element selecting module is configured to select one of the media forwarding elements for the additional media data stream taking into account the stored information, wherein for the selection the forwarding element selecting module checks based on the stored information whether the set up 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, the forwarding element selecting module is configured to exclude said one media forwarding element from the selection of the media forwarding element for the additional media data stream. - View Dependent Claims (11, 12, 13)

14. A media forwarding element configured to forward a media data stream through a network, the media forwarding element comprising:
-
processing circuitry operative as a source identification module configured to identify at least a first area of the network from which media data streams are received; processing circuitry operative as a load identification module configured to identify a load level of the media forwarding element and configured to identify how the media data streams from the first area contribute to the load level of the media forwarding element; and a transmitter configured to transmit a load message to a control node which selects the media forwarding elements for the different media data streams in the network, wherein the load message contains the information about the load level of the media forwarding element and about how the media data streams from a first area of the network contribute to the load level of the media forwarding element. - View Dependent Claims (15)

16. A non-transitory computer-readable medium storing a computer program comprising program instructions that, when executed by processing circuitry in a control node associated with a network having a plurality of media forwarding elements, configures the control node for selecting one of the plurality of media forwarding elements, said computer program comprising program instructions to configure the control node to:
-
receive 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; store the received information in a storage unit of the control node; receive 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; and select 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 whether the set up 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 from the selection of the media forwarding element for the additional media data stream.
