On Best-Effort Utility Accrual Real-Time Scheduling on Multiprocessors
We consider the problem of scheduling real-time tasks on a multiprocessor system. Our primary focus is scheduling on multiprocessor systems where the total task utilization demand, U, is greater than m, the number of processors on a multiprocessor system---i.e., the total available processing …

Soft Real-Time Switched Ethernet: Best-Effort Packet Scheduling Algorithm, Implementation, and Feasibility Analysis
… a MAC-layer packet scheduling algorithm, called Best-effort Packet Scheduling Algorithm(BPA), for real-time switched Ethernet networks. BPA considers a message model where application messages have trans-node timeliness requirements that are specified using Jensen's benefit functions. The …

Predicting sandbagging on sideline concussion tests using performance validity tests
… between individuals asked to provide their best effort or sandbag. Identifying individuals who provide suboptimal effort at baseline is an important task because it will ultimately improve our abilities to detect true injuries and reduce negative and long-term effects associated with …

Distributed Resource Allocation in Contention-Based Wireless Networks
… to realtime traffic, BEP for rate policing of best effort traffic and GCA for flexible and efficient bandwidth allocation of best effort traffic. This thesis also describes a novel framework, QPART, that provides reactive admission control for a MAC layer approach. All these schemes are fully …

Delivering personalised advertising in IMS-based IPTV through direct marketing
… open Internet. However, since the Internet is a best effort network, these services are not associated with any Quality of Service (QoS) and Quality of Experience (QoE) guarantees. Furthermore, security cannot be guaranteed when using these services over the open Internet.

Memory Optimizations for Distributed Stream-based Applications
… locally; however, they base these decisions on best-effort global information obtained from other components of the distributed application. The Adaptive Resource Utilization (ARU) algorithm analyzes the dynamic relationships between the production and consumption of data items. It uses this …

Adaptive multiple description mode selection for error resilient video communications
… the potentially harsh conditions present on best-effort networks like the Internet, including variations in available bandwidth, packet losses, and delay. Multiple description (MD) video coding is one approach that can be used to reduce the detrimental effects caused by transmission over …

Scalable video transportation using look ahead scheduling
… network. As the quality of visual content in a best-effort network is susceptible to average bandwidth availability, packet loss, packet delay and packet delay variation (jitter), the study proposes a scheduling algorithm and buffering technique. To combat the variation of delay (jitter) in a …

Network level performance of differentiated services (diffserv) networks
… Forwarding (EF), Assured Forwarding (AF) and Best Effort (BE). In this dissertation, the performance of DiffServ networks at the network level, such as end-to-end QoS, network stability, and fairness of bandwidth allocation over the entire network have been extensively investigated. It has …

Video transmission over constrained bandwidth channels
… video. It is, therefore, attractive to develop best effort services targeted for a particular media type (e.g., video). Such a service should provide graceful performance degradation as resources become scarce by exploiting the particular characteristics of the media type. In this thesis, we …

Discrete-time queueing models with priorities
… traffic gets transmission priority over best-effort traffic. Our results predict the influence of priority scheduling on the QoS (Quality-of-Service) of the different types of traffic.

Performance evaluation of AAL2 over IP in the UMTS access network Iub interface
… to the RNC. Currently IP routes packets based on best-effort which does not guarantee QoS, To provide QoS, MPLS integrated with DiffServ is proposed to support different QoS levels to different classes of service and fast forward the IP packets within the lub interface. To evaluate the performance …

Localised Routing Algorithms in Communication Networks with Quality of Service Constraints. Performance Evaluation and Enhancement of New Localised Routing Approaches to Provide Quality of Service for Computer and Communication Networks.
… increasing attention in the Internet industry. Best-effort applications are now no longer acceptable in certain situations needing high bandwidth provisioning, low loss and streaming of multimedia applications. New emerging multimedia applications are requiring new levels of quality of services …

Packet scheduling algorithms in LTE systems
… &loss sensitive) for example video conferencing. Best effort users are an example of NRT services that do not have exact requisites and have been allocated to spare resources. Reaching higher throughput has sometimes resulted in unfair allocation to users who are located far from the base station …

Challenges in Managing Information Extraction
… we extend our declarative framework to enable best-effort IE, allowing developers to more easily write and refine approximate IE programs. A key idea underlying these solutions is that many of the principles behind RDBMSs for managing structured data can be extended to IE for managing …

Networking Mechanisms for Delay-Sensitive Applications
… and networked games. While the single best-effort service of the current Internet favors throughput-greedy traffic by equipping congested links with large buffers, long queuing at the congested links hurts the delay-sensitive applications. Furthermore, while numerous alternative …

Does cognitive control affect successful "sandbagging" of concussion symptoms?
… is dependent upon athletes giving their best effort. If an athlete fakes poor performance or “sandbags”, a future injury may go undetected. Therefore, the purpose of this study was to determine if the SportGait concussion baseline assessment detects differences between participants …
