QoS - ATM versus Differentiated Services
نویسندگان
چکیده
Due to the increasing requirements on quality of service (QoS) for multimedia applications, wide area networks must be able to provide end-to-end performance guarantees. The ATM protocol, which offers an extensive traffic management functionality, achieves QoS in networks by providing various categories with different quality of service features. However, it is expensive and incompatible to the existing Internet infrastructure. On the other hand side, the ”best effort” service of the IP protocol is not able to fulfill these demands.

End-to-end QoS provisioning across heterogeneous domains
Heterogeneity with respect to networking technology is increasing, for example, considering QoS support. Different QoS have been developed for the Internet and for ATM networks. In the context of the Internet, integrated services (IntServ) as well as differentiated services (DiffServ) are considered. As a result, networking scenarios with different QoS models being applied in different domains ...
متن کاملAnalysis and Rating of QoS Approaches for E-Service Infrastructures
Implementing e-services successfully requires an adequate service infrastructure which delivers a solid base for reliable services. A major part of this service infrastructure is the transport infrastructure which e.g. constitutes the Internet. This transport infrastructure is responsible for delivering a reliable end to end transport service with different service levels which is a prerequisit...
متن کاملELISA: European Linkage between Internet Integrated and Differentiated Services over ATM
Nowadays we are witnessing the growth of Internet at an unprecedented rate. However, the current Internet does not guarantee Quality of Service for user flows, which prevents the provision of good quality for multimedia streaming applications over long distance. This led to the development of the Integrated Services architecture and recently to the Differentiated Services architectures. On the ...
متن کاملEnd-to-end QoS for differentiated services and ATM internetworking
The Internet was initially design for non real-time data communications and hence does not provide any Quality of Service (QoS). The next generation Internet will be characterized by high speed and QoS guarantee. The aim of this paper is to develop a prioritized early packet discard (PEPD) scheme for ATM switches to provide service differentiation and QoS guarantee to end applications running o...
