The current Internet provides only "best effort" services, however, applications and users expect different QoS (Quality of Service). To meet these requirements, the differentiated services (DiffServ) architecture is introduced. Because DiffServ is regarded as the foundation of the next generation Internet QoS architecture, it is helpful to design a DiffServ Router (DSR) and evaluate its performance. We first analyze the specifications on DSR and then outline the modules required to construct a DSR based on IETF standards and drafts. In order to evaluate the performance of DSR, a prototype DSR is provided and implemented in the Network Simulator. Evaluations of the prototype DSR show that different structures and parameters affect the performance of DiffServ services. The results of prototype DSR simulation are useful for the design of future routers
