Internet Service Architectures and ATM - The ELISA Approach

This chapter reports on design, implementation and experimentation of a network architecture that supports Quality of Service (QoS) for Internet applications. The new architecture supports the Integrated Services as well as the Differentiated Services approaches in a smoothly integrated way and uses the capabilities of an underlying ATM network to realize QoS. The enhancements to the existing network infrastructure are deliberately limited to the integration of a single new type of network element called the Edge Device. The chapter presents the network architecture, the implementation of the components as well as on business models and scalability analysis.
