A Cloud Computing Platform Based on P2P

In recent years, the technology of cloud computing has been widely applied in e-business, e-education and etc.. Cloud computing platform is a set of Scalable large-scale data server clusters, it provide computing and storage services to customers. The cloud storage is a relatively basic and widely applied service which can provide users with stable, massive data storage space. Our research shows that the architecture of current Cloud Computing System is central structured one, all the data nodes must be indexed by a master server which may become bottle neck of the system. In this paper, we propose a new cloud storage architecture based on P2P and design a prototype system. The system based on the new architecture has better scalability and fault tolerance.

A Novel Solution of Distributed Memory NoSQL Database for Cloud Computing

The traditional relational database to online storage are becoming increasingly problematic: the low performance do not gracefully meet the needs of mass data, the storage approaches of massive data are still not perfect presents. NoSQL and distributed memory database technologies have the potential to simplify or eliminate many of these challenges. NoSQL database technologies can provide Key-value style of data storage and largely ensure high performance. Distributed memory database technologies provide a means for easily store mass data in cloud in a dynamic and scalable manner. This paper argues for a new architecture called CDSA, which is a distributed memory NoSQL database architecture for Cloud computing to improve the performance of querying data and ensure mass data storage in cloud by using rational strategy. Furthermore, add or deleted any node from the distributed database cluster, the others node can work without stop service. We believe that CDSA can provide durable storage with high throughput and lower access latency.

An implementation of the online-payment platform based on SaaS

With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster, Online-payment platform is needed urgently. In this paper, the protocol in the bank-side is analyzed, and then payment platform architecture is proposed which is based on the SaaS standard and supports distributed deployment. Finally, Key technologies applied to imply this platform are also described in detail.

A study on the extraction and application of customer perception indexes in mobile network

Mobile informational strategy has a higher demand on the network supporting system and aims at the implementation of user oriented service management. As the indexes of customer perception are the direct reflection of the network quality, it is particularly important to analyze the indexes. In this paper, varieties of factors affecting customer experiences on the network quality are analyzed. A customer perception template is designed based on the related standards of QoE and the 5W model; a set of common extraction methods of customer perception indexes are given. According to the practical application of the customer perception template, the contribution coefficient of customer perception indexes that ha ve a great influence on the service quality are achieved by the statistical analysis model.

A carrier-grade service-oriented file storage architecture for cloud computing

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. So, we can also use the cloud computing to solve the problem of large-scale file storage. Cloud-based file storage system is a high reliability, high consistency and high availability large-scale file storage system. In this paper, we design a service-oriented file storage architecture for cloud computing, for dealing with the problem of the file storage in a carrier-grade information system. Furthermore, we provide solutions to prevent system crash.

A solution of Web Services combination based on JBPM

With the emergence of new business, the traditional Internet products can no longer meet the diverse needs of market. It costs much to develop new businesses and lots of the work in the development is reduplicate. So the best way is to find a solution that enables us to use the existing business to meet the change in demand. Service Oriented Architecture (SOA) with Web Service technology can transform the traditional business products into services. And Business Process Management (BPM) can combine Web Services. So the combination of SOA, Web Service and BPM can offer us a good solution. In this paper, we propose a combined service framework which is based on Java Business Process Management (JBPM). The functions of the framework are combining several heterogeneous Web Services, packaging them into a single Web Service and provide certain transaction control. With the framework, services providers can quickly response to the diversity needs of customers using the existing services.

A new service delivery open platform (SDOP) architecture

Grid computing, utility computing, P2P computing, service computing and cloud computing, such as technological development is leading the future of networks resources, services resources, data resources toward shared, on-demand, and the tendency of promoting utility. To develop an internationally advanced course of study on service sciences has enormous opportunities, especially in service composing, service providing and the quality of service. However, there is not a complete framework for service delivery platform enables the open sharing of service resources, on-demand services delivery, service capabilities together combination, and service capacity delivery. In this paper, we introduce the layered architecture of service delivery open platform (SDOP), and particularly describe the components and the functions of SDOP. In conclusion, we present our recommended SDOP architecture and point out that the horizontal, layered SDOP architecture will help service operators to build a new service management and operation platform, such as B2B electronic commerce, digital education and digital medical, that provides security credible integrated services and open access to heterogeneous data, massive resources network capabilities and services capabilities.

A service routing method for E-Commerce service

In this paper, a service routing method is proposed to support the pervasive E-commerce. To offer flexible routing control across multiple service domains, a customized route computation should be offered. In our method, a QoS-routing protocol is designed to select end-to-end paths that satisfy user requirements. And global QoS is guaranteed by the runtime QoS monitoring and dynamic adjustment.

A SOA-based business Grid solution

Nowadays, Grid computing is moving from sharing computing power and storage resources to sharing business resources, including any abstract business entities and resources. The new trend brings a big challenge, since these universal business resources typically do not belong to the same level. Describing them is already difficult; describing them in a unified way is even more difficult. Business process requires runtime coordination, asynchronous integration, notifications, and state and transaction management. The present Grid solutions generally lack a way to quickly and easily interact and integrate with external business processes and services provided by different localized Grids using a secure, affordable, and manageable approach. Therefore, this paper presents flexible solution framework to enable business resource sharing within and across organizational boundaries in a secure and manageable fashion.

An electronic contract services platform based on trans-domain convergence trust model

Global e-commerce has become increasingly active, innovative business model, third-party e-commerce services is entering a rapid growth opportunity. Electronic contract becomes the most important trends of electronic transactions, purchasing, supply and marketing platform in Internet. However, most businesses continue to check compliance using paper contracts because its difficult to interpret complex business vocabulary and legal jargon. Thus, more research is needed to develop a creditable e-contract framework and supply contractual services which comply with relevant laws. In this paper, after discussing legal issues of e-contract and administration department supervision, an electronic contract services platform is proposed based on the trans-domain convergence trust model. The e-contract services platform is supported by the third-party CA center and the third-party authority of time source provider, which can provides the safe, reliable e-contract services for various e-commerce businesses.
