Abstract:The current trends in the development of real-time Internet applications and the rapid growth of mobile systems, indicate that the future Internet architecture will have to support various applications with different Quality of Service (QoS) requirements, regardless of whether they are running on a fixed or mobile terminals. Enabling end-to-end QoS over the Internet introduces complexity in several areas starting from applications, network architectures, but also in network management and business models. It becomes even more complex when one is introducing QoS in an environment of mobile hosts, wireless networks and different access technologies, due to scarce resources. Consequently, QoS deployment in the Internet represents one of the most challenging research topics of computer networks community today. The efforts to enable end-to-end QoS over the Internet have led to the development of two architectures, the Integrated Services architecture and more recently, the Differentiated Services architecture. Although fundamentally different, both architectures are designed for QoS support on the Internet. The focus of this document is the interoperability between the Integrated and Differentiated Services architectures with the objective on applicability to both end-to-end wired and wireless Internet QoS deployment. This document presents a general Integrated Services / Differentiated Services architecture design with specific requirements and accordingly a detail design of the boundary router. The role of this boundary router is to handle the Integrated and Differentiated Services interoperability, in a wired and wireless Internet environment. In order to prove the feasibility of the boundary router design a basic prototype implementation has been developed.
