The unprecedented scale of Information Technology (IT) service delivery requires careful analysis and optimization of service… Expand The marketing decision models field has produced many striking developments that have had a dramatic impact on practice. However… Expand Many aspects about Optical Packet-Switching (OPS) networks have been studied in the last few years and it has been shown that… Expand The ability to provide different Quality of Service (QoS) guarantees to traffic from different applications is a highly desired… Expand Abstract Ethernet is now conquering the field level in automation technology. Realtime behavior is a knock-out criterion… Expand Recent theoretical results show that it is optimal to allow interfering sources to transmit simultaneously, as long as they are… Expand This paper describes an adaptive service differentiation scheme for QoS enhancement in IEEE 802.11 wireless ad-hoc networks. Our… Expand We examine the issues that arise in the definition, deployment, and management of policies related to QoS in an IP network. The… Expand We consider the problem of optimal scheduling of a set of jobs obeying in-tree precedence constraints, when a number M of… Expand We conjecture that the equilibrium waiting-time distribution in an M/G/s queue increases stochastically when the service-time… Expand
