Priority-based Network Services

چکیده
Although today’s Internet predominantly uses the flat-fee pricing scheme, the need for more sophisticated pricing has grown, especially for domains where bandwidth resources are scarce and expensive. This paper focuses on how to determine the price vector that maximizes the system revenue in priority-based networks. Similar problems have been examined using equilibrium analysis, but the assumptions needed to produce a static equilibrium may not hold in some realistic network environments. We propose a new method that does not require such assumptions. First, we have developed a method for computing the expected revenue for a given price vector. Then, instead of exhaustively trying out all the possible price vectors, we reduce the search space based on a set of pruning rules and apply a heuristic search to the remaining search space to find the near-optimal price vector. We demonstrate that the proposed scheme finds a near-optimal price vector efficiently, and compare our method with the equilibrium analysis.

One of the primary goals of conservation portfolio selection approaches is to create a functional landscape or network of sites that can support all elements of biodiversity and minimize the environmental risk to critical habitats and species. As human activities, especially roads network development, can be regarded as one of the most important risk elements for the valuable habitats and s...
متن کاملA User Behavior Clustering Based Fault Pre-detection Mechanism for QoE Assurance on Mobile Devices ⋆
Pre-detection mechanisms are often used to ensure the users’ QoE on mobile devices before potential service/application malfunctions really occur. In order to improve the efficiency of pre-detection, an optimized detection mechanism is proposed. In the mechanism, a priority set of services is selected by considering user’s dependency degree on services, service’s priority and network load. Firs...
متن کاملPriority Based Forced Requeue to Reduce Worst-Case Latencies for Bursty Traffic
In this paper we introduce Priority Based Forced Requeue to decrease worst-case latencies in NoCs offering best effort services. Forced Requeue is to prematurely lift out low priority packets from the network and requeue them outside using priority queues. The first benefit of this approach, applicable to any NoC offering best effort services, is that packets that have not yet entered the netwo...
متن کاملMulti-Level Access Priority Channel Allocation with Time Threshold in Global System for Mobile Communications (GSM) Networks
The focus of this work is on how the congestion experienced on the GSM network can be minimized. The voice calls is broken into sub-classes of services and a level of priority is established among the classes so that the most urgent and important service will have access to the channel by preempting the lower priority services during congestion. The voice communications over the GSM network usi...
