Pezaros, D. and Hutchison, David (2001) Quality of service assurance for the next generation Internet. In: The Second Postgraduate Symposium in Networking, Telecommunications and Broadcasting (PGNet'01), 2001-06-182001-06-19, Liverpool, UK.
The provisioning for multimedia applications has been of increasing interest among researchers and Internet Service Providers. Through the migration from resource-based to service-driven networks, it has become evident that the Internet model should be enhanced to provide support for a variety of differentiated services that match applications and customer requirements, and not stay limited under the flat best-effort service that is currently provided. In this paper, we describe and critically appraise the major achievements of the efforts to introduce Quality of Service (QoS) assurance and provisioning within the Internet model. We then propose a research path for the creation of a network services management architecture, through which we can move towards a QoS-enabled network environment, offering support for a variety of different services, based on traffic characteristics and user expectations.
