QoS support using DiffServ

In the current internet there is a demand for (high) bandwidth availability e.g. for VoIP and streaming video. There are several QoS architectures which can provide these services for certain packet streams. The best known architectures are Integrated Services (IntServ) and Dierentiated services (DiServ). This paper provides a survey of a number of DiServ solutions. Also a comparison of these solutions is provided, giving the most eective solution.
