Abstract- Providers must interact more closely with each other for providing end-to-end QoS for the global Internet. The focus of this paper is to propose 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 QoSaware 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 at the IP layer. The concepts of how to build such agreements are discussed and models for inter-domain QoS peering are proposed. By taking into account the loosely coupled structure of the Internet, we adopt a hop-by-hop, cascaded model in which each provider establishes agreements with its directly attached peers. Once these agreements are in place and networks are provisioned and engineered, QoS-based services can be offered. Targeted value-added services are identified and the methods of supporting the bidirectionality for these services are also proposed.
