Quality of Service (QoS) is a basic functionality that the Internet needs to be able to cope with when the applications increased in number and varied in use. Internet QoS issues concerning the Internet involves many different areas: end user QoS, ISP network QoS, backbone QoS. Backbone QoS is the problem concerning traffic engineering and bandwidth. ISP network QoS is one of the major problems in the Internet, In this paper, we would like to present an architecture model for QoS enabled ISP networks. This model is based on differentiated services and is connected to QoS or non-QoS enabled backbones for IP upstream and downstream QoS traffic. At the end of paper, an example of VoIP application is introduced.
