Abstract
Architecting networks capable of providing scalable, efficient, and fair services to users with diverse QoS requirements is
a pressing problem. The two principal issues are: design of “good” per-hop behavior and edge control. In previous work [2][3], we studied aggregate-flow QoS control from a noncooperative resource provisioning context. In [20], the framework was generalized by, one, solving an optimal aggregate-flow per-hop behavior problem, and two, showing how
it can be used coupled with end-to-end label control to facilitate scalable and fair QoS when driven by selfish users and
service providers. In this paper, we focus on optimal aggregate-flow per-hop control and complement analysis by experimental
performance evaluation. We show that user-specified, diverse QoS is efficiently facilitated over the optimal per-hop behavior
network substrate using adaptive label control end-to-end.
