Abstract: The Internet provides a best-effort transfer service with no service guarantees. In the last few years, however, there has been growing interest in providing Quality of Service (QoS) guarantees in the Internet. It has been mainly driven by multimedia and real-time applications, which require a certain level of service. Thus, the IETF is working on the development of new proposals for supporting these applications by improving service quality. they include the Internet Integrated Services and Differentiated Services. In this paper, they are described and compared in terms of scalability, signaling support, service taxonomy, granularity of service provision, scope of the service, service coordination and service differentiation.
