Much attention has recently been given to the differentiated services (Diffserv) approach to provide Quality of Service (QoS) for IP networks. This packet-marking based approach to IP QoS is attractive due to its simplicity and ability to scale. Two of the most popular services proposed for the Diffserv approach are the Assured and Premium Services. In this work prototypical implementations of Diffserv components are described. The prototypes are used to study the single-queue, dual drop-preference model proposed as a basis for assured services in Diffserv.
