Architecting networks capable of providing scalable, efficient, and fair services to users with diverse QoS requirements is a challenging problem. The differentiated framework has advanced set building blocks comprised per-hop access point behaviors. We provide theoretical for reasoning about networks, constrained be implementable in IP networks. control incorporates assumptions, albeit weak, selfish user behavior service provider behavior. This necessitated by the essential role they play influencing end-to end QoS, without which an effective evaluation DiffServ architectures remains incomplete. show that there intimate relationship between properties exported edge control, "goodness" resource allocation attained noncooperative network environment. Our framework-Scalar Control-generalizes achievable setting scalar value packet headers, e.g., TOS field IP. develop theory optimal classifiers exhibit facilitate to-end via joint action aggregate flow per hop per-flow at edge. stability efficiency overall system when are allowed influence choice values DS edge, providers export costs commensurate received.
