ABSTRACT:
The method includes transmitting a quality-of-service (QoS) route request to discover routing based upon a QoS parameter, and the route request including a flow identifier and a QoS link metric. 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. The destination node, upon receiving the QoS route request, generates a reply including the flow identifier and updated QoS link metric for each discovered route, and the source node generates QoS route metrics based upon updated QoS link metrics in the replies. 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.
