This thesis puts forward a new solution to provide the reliable network to the Internet Service Provider (ISP). This study mainly focuses on the ISPs network to provide reliability and the load balancing. It offers a guide line for the best reliable solution to the ISPs, individual organizations or other types of service providers which are engaged in providing reliable communications to their subscribers. These reliable services may be real time communications which include weather forecasts, tracking systems, online Internet protocol TV (IPTV) programs and many other ISPs services which are totally depend on the reliable network. With the appearance and expansion of Internet subscribers all over the world, ISPs services are becoming more popular. The rapid increase of connection-demand and highly traffic network is the main reason behind the need to scale reliable network. To offer better solutions, a new theoretical and practical approach should be considered that can cover the reliable network. The suggested network structure monitors the links, spreads the network traffic with multiple devices and takes a backup (redundant) link automatically when changes occur in the network topology. In order to support the redundancy, load balancing and reduce the failover time, the hot standby routing protocol (HSRP) is implemented on the suggested network. As we have analyzed that in any network, scalability bringing to raised the network traffic broadcast issue. Broadcast storms can be prevented by setting threshold values of traffic-filters. The threshold level helps to control broadcast traffic in networks. With regard to suggested solutions, it is necessary to observe the limitations and advantages of the recommended reliable network structure. Therefore, this research will include the advantages and limitations of the techniques used to offer ISP services such as scalability, security and IPv6.

We developed a price-based resource allocation scheme for Differentiated Service (DiffServ) data networks. The DiffServ framework was proposed to provide multiple QoS classes over IP networks. Since the provider supports multiple service classes, we need a differentiated pricing scheme, as supposed to the flat-rate scheme employed by the Internet service providers of today. Charging efficiently is a big issue. The utility of a client correlates to the amount of bandwidth allocated. One difficulty we face is that determining the appropriate amount of bandwidth to provision and allocate is problematic due to different time scales, multiple QoS classes and the unpredictable nature of users. To approach this problem, we designed a pricing strategy for Admission Control and bandwidth assignment. Despite the variety of existing pricing strategies, the common theme is that the appropriate pricing policy rewards users for behaving in ways to improve the overall utilization and performance of the network. Among existing schemes, we chose auction because it is scalable, and efficiently and fairly shares resources. Our pricing model takes the system's availability and each customer's requirements as inputs and outputs the set of clients who are admitted into the network and their allocated resource. Each client proposes a desired bandwidth and a price that they are willing to pay for it. The service provider collects this information and produces parameters for each class of service they provide. This information is used to decide which customers to admit. We proposed an optimal solution to the problem of maximizing the provider's revenue for the special case where there is only one bottleneck link in the network. Then for the generalized network, we resort to a simple but effective heuristic method. We validate both the optimal solution and the heuristic algorithm with simulations driven by a real traffic scenario. Finally, we allow customers to bid on the duration for which the service is needed. Then we study the performance of those heuristic algorithms in this new setting and propose possible improvements.

Under the four forces of opening up of domestic telecommunication market, breakthroughs in information and communication technology, changes in consumer demand, and supplier¡¦s race for economic efficiency, industry structures have transformed. What used to be three distinct industries of divergent directions of development ¡V network service (computers), telecommunication (telephones) and cable television (television), are interacting. The market is growing rapidly with combined digital flow of the three industries. Broadband internet played a key role in such transformation. ADSL broadband internet service has prospered in recent years. As the internet population approach maturity, the market has changed focus from quantity to quality. There are two major challenges to fixed network internet service providers are: To increase market share by attracting more customers to its service base, and retain customers to minimize loss of customers. Telecommunication service providers attract new customers by offering special prices with gifts, they retain customers by elevating switching cost and long term contracts. But the result of price-cutting competition was erosion of profit margin. Customer loyalty is also swayed by low prices met by competitors. Under such intense competitive environment, service providers are actively developing digital content and making investment in fiber optic broadband to mitigate loss. It is hoped that richer internet content and faster speed broadband can attract more customers and increase customer revenue contribution. The subject of this study are ADSL broadband internet users in the greater Kaohsiung area, the regions surveyed include Kaohsiung County and Kaohsiung City. A questionnaire was used as the data collection tool. The survey was conducted on a convenient sample. Data was analyzed using SPSS statistical software. The influence of customer¡¦s expected future benefits, overall customer satisfaction and marketing strategies on customer retention were investigated. Furthermore, the interaction effects were also reviewed. The results of the study are: I.The most important factor in influencing customer retention is overall customer satisfaction, followed by marketing strategy and customer¡¦s expected future use. Further results are derived from analysis: 1.Overall customer satisfaction, customer¡¦s expected future use and marketing strategy showed significant positive influence on customer retention. 2.The influence of overall customer satisfaction, customer¡¦s expected future use and marketing strategy on customer retention vary in strength. 3.Marketing strategy showed significant positive influence on overall customer satisfaction and customer¡¦s expected future use. 4.With respect to the degree of influence on customer retention, overall customer satisfaction showed greater influence than marketing strategy and customer¡¦s expected future use. II.Customers exhibit high expectations for future use¡C Telecommunication service provider satisfying the following ¡§customer¡¦s expected future use¡¨ will significantly enhance customer retention. 1.Provide value-adding services. 2.Provide more value-adding application content. 3.Offer better prices. 4.Exchange fiber optic with ADSL in the future at free of charge

This dissertation examines how customers' attribution for service failures and expected recovery in online service encounters are influenced by whether the recovery efforts are satisfying or dissatisfying to the customers; the relationship between satisfaction and other behavioral outcomes such as intention to remain and word-of mouth is examined. Many customers are using the Internet to purchase products and services, pay bills online, and make hotel and airline reservations. The Internet service recovery encounter warrants special attention because of its inherent ramifications such as the ease of attributing failure to the service provider after a service failure, the lack of interpersonal relationship, and the ease of leaving one service provider for another. The purpose of this study is to explore some of the importance of Internet service recovery mechanisms relative to customer's attribution for failure, expected service recovery, satisfaction, and intent to remain. This study further seek to explore how these mechanisms can be employed by the service providers to improve customer satisfaction, minimize negative word-of-mouth, and improve the firm's profitability. Many studies have examined customer satisfaction/dissatisfaction in traditional retailing, and the antecedents of the unsatisfactory behavior however, the same cannot be said of the Internet service encounters despite ecommerce revolution and its impacts on retailing and service encounters. A conceptual framework of recovery expectation and satisfaction in Internet based service encounters is presented, and a scenario-based experimental design is developed to measure the constructs. A web-based data collection was employed and the collected data were analyzed using correlation and regression analysis to provide answers to the research questions. The results of the analyzed data were discussed and presented. The findings overwhelmingly support all the hypotheses and contribute to the field of marketing by exploring some issues that might be unique to the online shopping experience and add more to the body of literature on online service failure and recovery management. The managerial implications, limitations, and future research directions are also presented.
