A New Perspective for a Global QoS-based InternetPublished online: Apr 6, 2017
Several Quality of Service (QoS) architectures and mechanisms have been proposed by standardisation bodies. However, those proposals were not always aligned with the spirit of IP networks. Furthermore, most research activities have focused to date on supporting QoS only within a single administrative domain. In this paper, we demonstrate that it is possible to provision QoS-enabled services that maintain the ability to easily connect any pair of users worldwide. For this purpose, we introduce the notion of Meta-QoS-Class and demonstrate its relevance for building QoS-enabled services across multiple domains. We then show how a QoS-enhanced Border Gateway Protocol (q-BGP) can be used together with Meta-QoS-Classes, for building a set of parallel Internet planes with different QoS capabilities. This concept opens up a new perspective for a global QoS-based Internet.
