    Recent Advances in Providing QoS and Reliability in the Future Internet Backbone
In order to provide end-to-end QoS for the global Internet, providers must interact more closely with each other. The focus of this chapter is to evaluate new techniques for providing these interactions in propagating QoS-based agreements among the set of providers involved in the chain of inter-domain service delivery. These providers' interactions occur at the service layer that result in the establishment of QoS-aware service agreements between providers. This needs to be supported by appropriate service management and traffic engineering capabilities per provider domain as well as by BGP-based interactions. The concepts of how to build such agreements are discussed and models for inter-domain QoS peering (interconnection) are proposed (source-based, cascaded, and bilateral models). By taking into account the loosely coupled structure of the Internet, the emphasis is put on cascaded and bilateral models, in which each provider establishes agreements with its directly attached upstream peers. Along with the proposed models, targeted value-added services are identified and the methods of supporting the bi-directionality for these services are also proposed. The focus is put on specification and evaluation of bilateral model for service level peering associated with meta-QoS-class concept [1], together with BGP-based interactions that are used to construct QoS-enabled Internet. © 2011 by Nova Science Publishers, Inc.
