This paper describes a hierarchical architecture of active policies that performs the management of a differentiated services (DiffServ) network. These policies monitor quality of ...
Utility Grids create an infrastructure for enabling users to consume services transparently over a global network. When optimizing workflow execution on utility Grids, we need to c...
— Rate adaptive multimedia streams offer significant system and client benefits over non-adaptive streams. These benefits come at the price of increased complexity in providin...
Service-Oriented Architecture enables the composition of loosely coupled services provided with varying Quality of Service (QoS) levels. Given a composition, finding the set of ser...
— We consider a queueing system with controllable service rate; for example, a transmitter whose rate can be controlled by varying the transmission power. For such a system we ob...
