1. A network client device comprising:
a media streamer for processing a media stream received at a first port of the network client device; and a set-up controller configured to transmit a set-up request message and a discovery message, wherein the set-up request message and the discovery message include first and second identifiers, respectively, with matching values in payload fields of the set-up request message and the discovery message, and wherein the set-up controller is configured to transmit a set-up request message and a discovery message by:
transmitting the set-up request message from a second port of the network client device to a first message handler of a server device via a first port of the server device, andtransmitting the discovery message from the first port of the network client device to a second message handler of the server device via a second port of the server device before receiving an acknowledgement of reception of the set-up request message by the server device, wherein the set-up controller is further configured to initiate transmission of the media stream from the server device to the first port of the network client device according to a set of transport parameters, and wherein the server device is configured to transmit the media stream to the network client device in response to comparing the matching values in the first identifier of the set-up request message and the second identifier of the discovery message.
