Abstract: The method includes nodes transmitting quality-of-service (QoS) route requests to discover traffic routing based upon a QoS parameter, and the QoS route requests including a traffic flow identifier. Each node calculates a node QoS tag value to make traffic admission control decisions, and each node determines whether to admit traffic in response to QoS route requests based upon the calculated QoS tag value and the QoS parameter of QoS route requests. Also, each node replies to QoS route requests to indicate whether the node can support the QoS parameter of the route request and admit the traffic, and each node polices admitted traffic based upon the traffic flow identifier to ensure that admitted traffic does not exceed the QoS parameter of the QoS route request.

Furthermore, the method includes each intermediate node determining whether the node can support the requested QoS parameter and, if so, updating the QoS link metric, forwarding the QoS route request, and temporarily reserving node resources.

Also, the source node selects a route to the destination node based upon the QoS route metrics, and transmits route confirmations to intermediate nodes on the selected route.
