In the case of congestion the competition of flows for obtaining network resources increases and since the network resources are shared between different flows, the fair allocation of them becomes a crucial issue. In this work, we propose a fair active queue management (AQM) mechanism based on a well-known economic model called supply and demand. AQM is an effective router-based approach for avoiding...
Take a research in depth on the modeling problem of service path selection based on SON. Firstly, the optimal model is built with the optimal goal of balanced loading and with the functional constraints of users for composed service and multi-QoS constraints. Then the layered method and improved Ant algorithm are adopted to solve this problem. Finally, a simulated emulation is made to the algorithm,...
To attract and serve an expanded customer base, telecommunication service providers need to provide more targeted, focused and personalized services, which brings challenges to both business model and technologies to development of value added services. In this paper, we introduce Service Storm, a novel self-service telecommunication Service Delivery Platform with Platform-as-a-Service technologies...
With the development of services computing technology, more and more voluntary services have been available on the Internet. When using voluntary services, users tend to obtain higher QoS (e.g., get more computational resources to improve throughput of the services) than they actually need because there is no cost. To control QoS of the voluntary services appropriately, it is necessary to design resource...
Cloud computing aims to give users virtually unlimited pay-per-use computing resources without the burden of managing the underlying infrastructure. We claim that, in order to realize the full potential of cloud computing, the user must be presented with a pricing model that offers flexibility at the requirements level, such as a choice between different degrees of execution speed and the cloud provider...
We believe that a market-based resource allocation will be effective in a cloud computing environment where resources are virtualized and delivered to users as services. We propose such a market mechanism to allocate services to participants efficiently. The mechanism enables users (1) to order a combination of services for workflows and co-allocations and (2) to reserve future/current services in...
To allocate cloud resources efficiently and obtain the maximum economic benefit are the major goals of the cloud resource providers and users. The objective of this paper is to present a novel cloud resource allocation algorithm named NECDA to overcome some of the shortcomings of the current mechanisms. A cloud resource allocation model of m*n type based on M/M/1 queuing system is established first...
As Grid technologies evolve quickly on Internet, research related to resource scheduling faces new opportunities and challenges. These new technologies, ideas and approaches provide a new environment for researching and developing the economy-based resource scheduling system. Aiming at the hierarchical Grid model, following utility optimization thinking, while an universal flexible utility function...
To cope with rapidly increasing Internet usage nowadays, providing Internet services using multiple servers has become a necessity. To ensure sufficient service quality and server utilization at the same time, effective methods are needed to spread load among servers properly. Existing load balancing methods often assume servers are homogeneous and consider only one type of resource, such as CPU....
Information infrastructures such as Internet have been a great success in the past few decades and gradually become mature, diversified user requirements continue to grow at a fabulous speed. Multiplex services on secure networked environments are now deemed as an application licensed to customers for use as a trustworthy service on demand. The flexible reconfiguration network is the next step to...
How to meet the QoS of the applications and improve resource utilization is an important problem in virtualized environment. In this paper, we propose a utility based resource allocation policy with QoS constrained in virtualized environment. Firstly, we build a model reflecting the mapping relation between performance metrics and resource allocation through Web server benchmarking experiments. Then,...
The Internet of services, as a global service oriented architecture, is a complex large scale system that presents many problems in the design and implementation of systems to autonomously manage, protect and tune it. Whilst the emerging data centres or service `cloud' represent a move towards centralization, computing power is becoming disembodied and is consumed where and when it is needed in a...
The current industry driven trend of providing flexible e-services lays the ground for the new research area "service value networks'' (SVNs). We observe a rising number of industry oriented publications provided by research departments of large companies such as IBM or SAP as well as the fact that more and more IS conferences offer special tracks on that issue. However, when it comes to formalizing...
The emergence of the Internet has forced a wealth of firms to explore a new form of channels of distribution, i.e., Internet channels. Nevertheless, few empirical studies undertake comprehensive Internet channels evaluation and provide direct evidence on their performance implications. In order to fill in the literature gap, this research employs super-efficiency data envelopment analysis (DEA) to...
Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision and they include Grid...
Personal computers and mobile devices connected in network provide a great potential to build distributed applications which can explore a wide range of available idle resources. They are called peer-to-peer applications (P2P) and play an important role in the evolution of the Internet. Whereas P2P transactions already dominate the worldwide bandwidth it mostly consists of file sharing, leaving out...
Distributed content delivering network (DCDN) will make use of the existing resources of the common Internet users in terms of storage space, bandwidth and Internet connectivity to create it. However, DCDN has some limitations that are inefficient using of storage space, reliability and having special load balancing (LB) algorithm. So, this paper proposes re-distribution based CDN (RDCDN) that overcomes...

Efficiency and fairness are main objectives in any system design and many choices in life are made based on their tradeoffs. This paper investigates the current trends in understanding and applying the fairness concept on the Internet. Then it studies and examines the extension of the fairness concept in the context of development and developing regions, where both the traditional lack of infrastructure...
Virtual networks and service overlay networks lease bandwidth from Internet autonomous systems to offer end to end quality of service at competitive costs. In this paper, we propose a novel network resource management approach, based on an economic model, which allows continuous optimizing of the network profit, while keeping acceptable grade of service. The proposal integrates leased link capacity...
