Abstract: A method may include receiving a request to establish a quality of service (QoS) policy that identifies a desired QoS associated with traffic being transported by a network; generating a QoS model based on the identified desired QoS, where the QoS model includes a class of service (CoS) and corresponding forwarding priorities associated with the traffic; retrieving a service level agreement (SLA), associated with a client device that is interconnected to a network node associated with the network, where the SLA includes a particular CoS and corresponding other forwarding priorities for packets associated with the client device; creating a QoS provisioning policy based on the QoS model and the SLA, where the creating includes mapping the CoS to the particular CoS or mapping the forwarding priorities to the other forwarding priorities; and transmitting, to the network node, the QoS provisioning policy that permits the network node to process the packets in a manner that complies with the QoS model or the SLA.
