This paper develops a framework for integrating contract markets with spot markets using tradable options for capacity. Sellers and Buyers may either contract for delivery in advance (the \contracting" option) or they may sell and buy some or all of their output/input in a spot market. Contract pricing involves both a reservation fee per unit of capacity and an execution fee per unit of output ...

IP multimedia subsystem (IMS) is over IP network architecture, but mobile IP cannot directly support session mobility controlled by session initiation protocol-based signaling. The long signaling delay for session reestablishment in application layer always results in session interruptions during the handoff. Therefore, handoff poses a challenge for quality of service (QoS) maintenance in IMS t...

As the increasing penetration of sustainable energy brings risks and opportunities for system reliability, at same time, considering multi-dimensional differentiation users’ reliability demands can further explore potential value resources in Integrated Energy Microgrid (IEM). To activate a market-oriented perspective flexibly optimize operational reservation dispatch, an optimal dispatching mo...

This paper addresses the issue of providing QoS services for Optical Burst Switching (OBS) systems. We propose a Linear Predictive Filter (LPF)-based Forward Resource Reservation method to reduce the burst delay at edge routers. An aggressive reservation method is proposed to increase the successful forward reservation probability and to improve the delay reduction performance. We also discuss ...

This paper describes distributed (or decentralized) protocols for establishing wavelength paths in point-to-point WDM networks. Distributed control improves reliability as well as scalability and reduces implementation cost of a network, but also presents major challenges in managing/allocating wavelengths eeciently. Two types of distributed wavelength reservation protocols are proposed and eva...

We consider the problem of reserving link capacity in a network in such a way that any of a given set of flow scenarios can be supported. In the optimal capacity reservation problem, we choose the reserved link capacities to minimize the reservation cost. This problem reduces to a large linear program, with the number of variables and constraints on the order of the number of links times the nu...

We introduce the concept of elastic reservation of bandwidth capacity to mitigate the problem of bandwidth fragmentation in LambdaGrids and present a network model which can support elastic reservations. We also define the Elastic Scheduling Problem (ESP), which succinctly captures the optimal utilization objective of elastic reservations. Analysis of ESP reveals that it is an NP-complete probl...

As a potential method for improving the resource utility, advance reservations is crucial for brokering computational resource in a predictable and efficient way. However, Conducting Advance Reservation efficiently in grid environment is not easy due to the insufficient support of the current grid architecture and the dynamic feature of grid resources. Based on a grid middleware Migol, this pap...

This paper addresses the issue of providing QoS services for Optical Burst Switching (OBS) systems. We propose a Linear Predictive Filter (LPF)-based Forward Resource Reservation method to reduce the burst delay at edge routers. An excessive reservation method is utilized to increase the successful forward reservation probability and to improve the delay reduction performance. We also discuss a...

As many travelers use online for their travel arrangement, hotels provide online reservation system, so as to take the benefits of internet marketing such as the cost reduction. However, there has been minimal research regarding a detailed examination of hotel booking Web sites and e-service performance on customers’ reuse intentions for online hotel reservation. This paper thus examines the ef...
