Extending QoS Support From Layer 3 To Layer 2

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.
