SYSTEM AND METHOD FOR QUALITY OF SERVICE (QoS) SETUP OF A NETWORK SEGMENT HAVING AN INTERMEDIATE DEVICE
First Claim
1. A method for quality-of-service (QoS) setup in a network segment of a network that includes a source device for transmitting a data traffic stream, a sink device for receiving the traffic stream from the source device through an intermediate device of the network segment, and a QoS parameter holder (QPH), the method comprising:
- detecting at the intermediate device a traffic stream identifier from the traffic stream;
querying the QPH for QoS parameters associated with the detected traffic stream identifier;
sending QoS parameters from the QPH;
receiving at the intermediate device QoS parameters from the QPH; and
configuring the network segment with the QoS parameters received at the intermediate device.

Abstract
A system and method configures quality-of-service (QoS) in a segment of a network that has multiple segments with an intermediate device between the segments. The network may be a home network for the transmission of audio-video traffic streams between a media server or source, like a personal computer (PC), and a media renderer or sink, like a digital TV, with the intermediate device being a router, bridge or hub connected to its own network segment and located between the source and sink. One of the network devices contains a QoS parameter holder (QPH). After QoS has been configured in the source and sink and the traffic stream established, the intermediate device detects the traffic stream and determines that it needs to set up QoS. The intermediate device queries the QPH with a traffic stream identifier. The QPH finds the traffic descriptor that matches the traffic stream identifier and returns to the intermediate device the traffic descriptor that includes the QoS parameters. The intermediate device then uses the QoS parameters to configure QoS in its network segment.

12. A method for configuring quality-of-service (QoS) in a local area network (LAN) having a plurality of devices including an audio-video (AV) media server for transmitting an AV traffic stream, an AV media renderer for receiving the AV traffic stream, and an intermediate device between the media server and media renderer through which the AV traffic stream passes, the intermediate device being connected to a network segment, the method comprising:
-
providing in one of the devices a QoS parameter holder (QPH); signaling the media server and media renderer from the QPH with the QoS parameters; detecting at the intermediate device a traffic stream identifier from the AV traffic stream; querying the QPH from the intermediate device with the detected traffic stream identifier; sending from the QPH to the intermediate device the QoS parameters associated with the traffic stream identifier; receiving at the intermediate device the QoS parameters from the QPH; and configuring the network segment with the QoS parameters received at the intermediate device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
