This paper presents some of the results obtained by the application of Ethernet Layer 2 Quality of Service in IP networks. IP networks traditionally provide Quality of Service in Layer 3. However, since there is an enormous existing Layer 2 infrastructure, today's networks could benefit from the deployment of Layer 2 Quality of Service and the cooperation between Layer 2 Quality of Service and Layer 3 Quality of Service. In this paper, experiments are suggested and conducted and a scheme is suggested for efficient cooperation between Layer 2 and Layer 3 QoS provisioning.
