Residential broadband consumption is growing rapidly, increasing the gap between Internet service provider (ISP) costs and revenues. Meanwhile, proliferation of Internet-enabled devices is congesting access networks, degrading end-user experience, and affecting content provider monetization. In this paper, we propose a new model whereby the content provider explicitly signals fast- and slow-lane requirements...
Currently Internet of Things (IoT) and multimedia technologies have entered the healthcare field through ambient aiding living and telemedicine. However there are still several obstacles blocking in the way, the toughest ones among which are IoT interoperability, system security, streaming Quality of Service (QoS) and dynamic increasing storage. The major contribution of this paper is proposing an...
A terminal connected to a router has a private IP address. When this terminal sends a data packet to the service system via the router, the router will change the private IP to a public IP, then tries to send the data packet to the server. The service system knows only the router's public IP as the destination address. So the response packet is delivered to the router, and the router cannot deliver...
The emergence of new applications on the Internet has created highly dynamic and changing traffic patterns. In order to route dynamic traffic with guarantee, quality of service without detection of traffic change becomes necessary. The security scheme using cryptographic key will be efficient enough to provide network confidentiality, but due to the time complexity and unavoidable growth of hackers...
Live multimedia streaming over the Internet has steadily gained popularity over the past decade primarily fueled by the growth in the available network bandwidth and rich multimedia applications. Various approaches to support live multimedia streaming can be broadly categorized into two alternatives, namely, IP multicast based and overlay based. While IP multicast based solution is dependent on the...
Wireless broadband internet has become one of the important projects to strengthen Taiwan's e-Infrastructure. This paper studies the service quality of wireless broadband internet applications from the consumer's viewpoint by conducted a questionnaire survey and statistical analysis. The design of questionnaire is based on Gronroos quality model. The attributes of wireless broadband internet service...
This paper reports on a study which evaluates electronic commerce service quality based on the dynamic fuzzy sets by improving the SERVPERF model. At first, this paper reviews literature on SERVQUAL, SERVPERF and some other electronic service quality evaluation model, then puts up with a dynamic multi-layer fuzzy evaluation method, and uses this method to improve the traditional SERVPERF framework...
Users always expect to acquire high quality services from online banking. Previous studies have found that website system quality is a main factor determining online users' initial adoption and usage. For their continuance usage, service quality may be a main determinant. This research proposes that online banking service quality, reputation and security influence users' continuance usage through...
As the Internet increasingly growth and the rapid transformation of the Internet into a commercial infrastructure, demands for service quality have rapidly developed, in this paper we presents a framework for the Internet QoS, which we call TaffyPume. TaffyPume can provide end-to-end QoS. In our tests, the TaffyPume shows good scalability and better than the Internet QoS methods before.
This paper is brought into being from the experience during the personalized information service system in digital library is developed. This system based on agent aims to improve the service quality and level of college library information management system under the concept of Lib2.0. Based on analyzing the recent research and application status of Lib2.0 personalized information service, and researching...
As the development of Service-Oriented Computing (SOC), more and more functional similar services are deployed over the Internet. Nowadays, service selection becomes a crucial issue to make SOC more applicable. Troublesome service will affect the whole SOC application which invokes the service. Therefore, when choosing services, not only the functional attributes but also the Quality of Service (QoS)...
The recent rapid increase in the number of HSDPA subscribers in Korea is likely the result of the providers' vibrant marketing activity (such as the handset subsidy)- a facilitating condition which has had more influence on HSDPA adoption than the unique fact that the 3G service provides video telephony, unlike the existing mobile telecommunication wireless high-speed Internet. Few studies, however,...
WiBro (Mobile WiMAX) is a broadband wireless internet service supporting for fixed, portable and mobile users, but enhancement of service quality in indoor environment is still necessary. WiBro femtocell is developed to expand cell coverage, increase system capacity and offer various multimedia service with high throughput in indoor environment. Three types of femtocell are designed according to the...
A wide range of Internet-based services that use reliable transport protocols display what we call thin-stream properties. This means that the application sends data with such a low rate that the retransmission mechanisms of the transport protocol are not fully effective. In time-dependent scenarios where the user experience depends on the data delivery latency, packet loss can be devastating for...
One of the key challenges in online businesses is how to measure service quality in order to have a better understanding of its consequences which holds a significant importance to customer satisfaction. In this paper, we ranked the dimensions of service quality that affect the customerspsila expectation in online shopping in Iran from the customerspsila perspective. The measurements used were based...
We introduce both high-speed transmitting and quality of system offering Internet services on the HFC (Hybrid Fiber Coaxial) network with low installation cost. It modulates the phase and the amplitude to the carrier wave signal of the IPBS (Internet Protocol Broadcasting Service) data being acquired from Layer 3 switch. The proposed system is effective to embody the HFC based high speed transmission...
This paper describes the development of KQIs (key quality indicators) for WiBro service (wireless broadband Internet service) provided by Korea Telecom. To take a customer-focused approach to service quality, we need KQIs to measure the level of service quality based on the customer experience. Therefore, in this paper, we essentially deal with the Web browsing service experienced by users as an internet...
NGN has been on the implementation phase, primarily focused on the replacement of PSTN. NGN carriers try to differentiate NGN from the current Internet for the service quality and reliability. Users of the current Internet, however, expect the early integration of NGN and the Internet, as Internet services have already been deployed into the society and daily life. In this paper, we address the interoperability,...
This paper tackles the problem of autonomic admission control for web clusters. The main contribution of this work is the proposal of a new session admission algorithm that self-configures a dynamic constraint on the rate of incoming new sessions to guarantee the respect of Service Level Agreements (SLA). Unlike other approaches, our policy does not need any prior information on the incoming traffic,...
