Network level performance of differentiated services (diffserv) networks
The Differentiated Services (DiffServ) architecture is a promising means of providing Quality of Service (QoS) in Internet. In DiffServ networks, three service classes, or Per-hop Behaviors (PHBs), have been defined: Expedited Forwarding (EF), Assured Forwarding (AF) and Best Effort (BE). In this …

Bandwidth management and quality of service
… needs of different types of users can be met. Differentiated services is seen as a possible solution to the bandwidth problem. Currently, however, the technology used on the Internet differentiates neither between users, nor between applications. The thesis focuses on current and anticipated …

A study of partnership models in distribution channels
… have been struggling to provide customers with differentiated services and satisfaction, and to capture their perception. They tried changing the relationship with dealers over multiple distribution channels in order to solve this issue. Through trials and errors the oil companies managed to …

Architecture design and performance analysis of practical buffered-crossbar packet switches
… The proposed mSMCB switch is extended to support differentiated services and long RTT. To support P traffic classes with different priorities, CICB switches have been reported to use N^2x k x L x P amount of memory to avoid blocking of high priority cells.The proposed SMCB switch with support for …
