End-wise admission control delegation for effective end-to-end quality of service

Despite the significant body of research that has been conducted on quality of service (QoS), the notion of a dominant approach to end-to-end (E2E) QoS remains elusive. Beyond the ever present issue of deployment, the complexity and limited speed of resource negotiation arising from per-hop or per-domain interactions limit the general utility of the existing approaches. In this paper, we propose a novel approach to make significant strides in practical end-to-end QoS by leveraging the over-provisioned nature of the core and cooperative interactions amongst end autonomous systems. Our approach, E3AC (End-wise delegation for End-to-End Admission Control), provides a framework for catalyzing QoS amongst end ISPs while dramatically reducing the setup latency for QoS negotiations
