In this paper we address how the 3GPP-defined end-to-end QoS bearer services (conversational, streaming, interactive and background) for UMTS can be mapped to the IETF-defined Differentiated Services (Diff-Serv) per hop behaviours (Expedited Forwarding (EF), Assured Forwarding (AF) and Best Effort (BE)). Such a mapping must be complemented with the appropriate DiffServ configurations of the routers. We have investigated how this can be done by building a laboratory network and using it as a testbed for our measurements. We present the results from our measurements in the test-bed. We also present some conclusions from these tests. Finally we give some general guidelines, based on our experiences, how to choose a good mapping.
