2. 1. Architectures for Service Differentiation in Overloaded Internet Servers

   Author : Thiemo Voigt; Peter Druschel; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Internet; Web Servers; Operating Systems; Service Differentiation; Admission Control; Information technology; Informationsteknik; Computer Systems; Datorteknik;

   Abstract : Web servers become overloaded when one or several server resources such as network interface, CPU and disk become overutilized. Server overload leads to low server throughput and long response times experienced by the clients. Traditional server design includes only marginal or no support for overload protection. READ MORE

4. 2. Distributed Multiple Access and Service Differentiation Algorithms for Wireless Networks

   Author : Thomas Nilsson; Per-Åke Wedin; Jerry Eriksson; Lennart Bondesson; Andrzej Duda; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Local Area Networks; Medium Access Control; Quality of Service; Resource Allocation; IEEE 802.11; IEEE 802.11e; Datatransmission; Datatransmission;

   Abstract : Communicating over a wireless channel poses many unique challenges not found in wired communication because of the special characteristics of the wireless channel. The capacity in a wireless network is typically scarce as a result of the limited bandwidth and many distinct phenomenons, like attenuation and interference, that work destructively on the received signals.

5. 3. Autonomous cloud resource provisioning : accounting, allocation, and performance control

   Author : Ewnetu Bayuh Lakew; Erik Elmroth; Hiaohui (Helen) Gu; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; distributed infrastructure; monitoring; accounting; performance modeling; service differentiation; business data processing; administrativ databehandling;

   Abstract : The emergence of large-scale Internet services coupled with the evolution of computing technologies such as distributed systems, parallel computing, utility computing, grid, and virtualization has fueled a movement toward a new resource provisioning paradigm called cloud computing. The main appeal of cloud computing lies in its ability to provide a shared pool of infinitely scalable computing resources for cloud services, which can be quickly provisioned and released on-demand with minimal effort.

6. 4. Multi-Echelon Inventory Control with Consideration of Emissions and Service Differentiation

   Author : Lina Johansson; Produktionsekonomi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : An increased focus on sustainability and initiatives towards green supply chains raises new challenges for efficient inventory control. This doctoral thesis addresses the consequences some of these initiatives have on the modelling of inventory systems and the resulting policy variables. READ MORE

7. 5. Scalable Self-Organizing Server Clusters with Quality of Service Objectives

   Author : Constantin Adam; Rolf Stadler; Giovanni Pacifici; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Autonomic computing; self-organization; decentralized control; web services; quality of service; Telekommunikation; Telecommunication; Telekommunikation;

   Abstract : Advanced architectures for cluster-based services that have been recently proposed allow for service differentiation, server overload control and high utilization of resources. These systems, however, rely on centralized functions, which limit their ability to scale and to tolerate faults. READ MORE
