<p>For allocating resources in a mesh communications network for setting up a data stream transmission from a talker device to a listener device via at least one node device, data paths being defined throughout the mesh communications network following a link-state routing protocol, each node device performs: receiving a stream reservation request for said data stream transmission; obtaining, from said stream reservation request, a path identifier identifying a data path via which said data stream transmission has to be set up, and an identifier of said listener device; determining via which output port of said node device the data path identified in the stream reservation request continues toward the listener device; checking whether there are enough resources, associated with the determined output port, to fulfil resources requirements of the received stream reservation request. And when there are enough said resources: temporarily reserving resources for said data stream transmission; and, propagating the stream reservation request toward the listener device. And when receiving for said data stream transmission a stream reservation response representative of a positive acknowledgement to said stream reservation request: effectively allocating the reserved resources; and, propagating the stream reservation response toward the talker device.</p> |
