Interworking between GPRS AND ISP for Wireless Internet Service of Mobile ISP Subscriber
2006 IEEE IFIP Network Operations and Management Symposium NOMS 2006, 2006Co-Authors: Jeong-hyun Park, Jong-heung ParkAbstract:In this paper we illustrate how visited mobile ISP subscriber can access home ISP via GGSN (gateway GPRS support node) on GPRS (general packet radio Service) network. We also introduce messages between GGSN and ISP for wireless Internet access of visited ISP subscriber, and a specific DHCP relay which can provide dynamic IP to visited ISP subscriber, and signaling for IP management using RADIUS authentication and account server for wireless Internet Service. The contribution of this paper is to suggest interworking solution between ISP and GPRS network for seamless Internet Service

A study of pricing strategy for Mobile Internet Service using clickstream data
2010 IEEE International Conference on Intelligent Systems and Knowledge Engineering, 2010Co-Authors: Ping Yuan, Guohong ZhouAbstract:With continued expansion of the Mobile Internet users scale, Mobile Internet played a more important role in customers' daily life. In order to decrease the users' perceived risk and consumption uncertainty, the Mobile Internet Services providers take the freemium pricing strategies as the common pricing strategy to attract or maintain their user base. However, although the freemium pricing strategies of Mobile Internet Services provider are continually enhanced, the empirical researches on how different freemium pricing strategies may affect users' website stickiness in different market segments, and how those freemium Services may affect the Mobile Internet Service providers' customer attraction or customer retention performance are still rarely. In order to fill in the academic research gaps: first, we will use the clickstream data to identify the relationship between freemium pricing strategies and the customers' website stickiness in different market segments; and then, we will develop a structured survey to examine whether the freemium pricing strategies may increase the Mobile Internet Service providers' customer attraction or customer retention performance ,namely, the customer satisfaction level, customer ownership ,and positive word of mouth. The results will supply more academic support for the Mobile Internet Service providers when they want to use freemium pricing strategies to improve the customers' website stickiness, customer attraction or customer retention performance.

New Internet Service Pattern Based on Asset Agent
2010 Ninth International Conference on Grid and Cloud Computing, 2010Co-Authors: Zhiwei XuAbstract:Currently, major Internet Services are designed for consumer/personal usage and it tightly depends on Service provider, which shows trends on monopolization. In this paper, we propose a new Internet Service model, PHCMM, based on systematic and thorough summary of contents' lifecycle. Equipped with PHCMM, we identify and analyze existing Internet Service patterns. Subsequently, we design a novel distributed Service pattern based on asset agent (AASP), which can decrease the clients' dependency on specific ICP/ISP, and also break the increasing monopolization of provider in some areas. The new Service pattern can also help to improve Service efficiency and extendibility, and guarantee Service with real “measurable, controllable and manageable”. We have applied this pattern into storage-assets and implemented an SAA (Storage-Asset Agent) system. Based on this system, we have instantiated the current Internet web mail Service. Experiments show that SAA under Advanced AASP can significantly reduce the Service workload on providers' side and completely eliminate the end users' dependency on specific Service providers.

A Survey on Blockchain-Based Internet Service Architecture: Requirements, Challenges, Trends, and Future
IEEE Access, 2019Co-Authors: Wenli Yang, Erfan Aghasian, Saurabh Garg, David Herbert, Leandro Disiuta, Byeong KangAbstract:The emergence of Internet protocol suites and packet-switching technologies tends to the considerations of security, privacy, scalability, and reliability in layered Internet Service architectures. The existing Service systems allow us to access big data, but few studies focus on the fundamental security and stability in these systems, especially when they involve large-scale networks with overloaded private information. In this paper, we explored the blockchain-based mechanism that aims to improve the critical features of traditional Internet Services, including autonomous and decentralized processing, smart contractual enforcement of goals, and traceable trustworthiness in tamper-proof transactions. Furthermore, we provide a comprehensive review to conceptualize the blockchain-based framework to develop the decentralized protocols for the extensive number of Internet Services. This comprehensive survey aims to address blockchain integration to secure Internet Services and identify the critical requirements of developing a decentralized trustworthy Internet Service. Additionally, we present a case study of the blockchain-based Internet of Things (IoT) for neuro-informatics to illustrate the potential applications of blockchain architectures. Finally, we summarize the trends and challenges of blockchain architectures that benefit a multitude of disciplines across all the Internet Service fields of interest.

scalable distributed data structures for Internet Service construction
Operating Systems Design and Implementation, 2000Co-Authors: Steven D Gribble, Eric Brewer, Joseph M Hellerstein, David E CullerAbstract:This paper presents a new persistent data management layer designed to simplify cluster-based Internet Service construction. This self-managing layer, called a distributed data structure (DDS), presents a conventional single-site data structure interface to Service authors, but partitions and replicates the data across a cluster. We have designed and implemented a distributed hash table DDS that has properties necessary for Internet Services (incremental scaling of throughput and data capacity, fault tolerance and high availability, high concurrency, consistency, and durability). The hash table uses two-phase commits to present a coherent view of its data across all cluster nodes, allowing any node to Service any task. We show that the distributed hash table simplifies Internet Service construction by decoupling Service-specific logic from the complexities of persistent, consistent state management, and by allowing Services to inherit the necessary Service properties from the DDS rather than having to implement the properties themselves. We have scaled the hash table to a 128 node cluster, 1 terabyte of storage, and an in-core read throughput of 61,432 operations/s and write throughput of 13,582 operations/s.
