An Overview on Inter-Domain Routing with Quality of Service*

Abstract

This study discusses various problems of inter-domain routing with Quality of Service and gives an overview of the currently proposed solutions. The problem arises when the traffic must pass through different Autonomous Systems and therefore the quality of service requested cannot be guaranteed. Several studies and solutions have been made to improve the end-to-end quality of service. We classify these solutions in this study into two categories: theoretical and technical solutions. We present the main proposed solutions for each category and we show the performance and limitations of each solution.
