Int-serv framework architecture and QoS implementation in the IPv6

Over past several years there has been a considerable amount of research in the new field of quality-of-services (QoS) support for distributed multimedia systems. To date, most of the work has been within the context of individual architectural layers. Current research work is concentrated in overall end-to-end support for multimedia communications and therefore in development of QoS architectures which incorporate QoS configurable interfaces and QoS driven control and management mechanisms across all architectural layers. A short survey of to date of QoS frameworks is presented and the IETF int-serv architecture framework for QoS in distributed multimedia systems are presented and discussed. Also a short review of QoS support in the new generation IP protocol IPv6 is presented.
