Research Of The Billing Of Distributed Software Service Based On Web Services

Software service provides a mechanism for business process reuse and sharing of Internet resources: information, software and hardware. The billing of software service is an important issue that should be considered in further application. Aiming at this problem, preconditions and characteristics of software service billing are discussed firstly. After pointing out the shortcomings of the billing schemes proposed by IBM etc., the billing process of SMS and WAP in value-added telecom services is investigated. In order to gain some valuable ideas, two Authentication protocol-Kerberos and RADIUS are consulted. In addition, security technology used in the SET protocol is also analyzed. Based on the above analysis and investigation, a billing scheme for distributed software service is proposed in this paper.The innovation and characteristics of this scheme mainly reside in: (1) Based on a feasible billing model, this scheme not only guarantee legal rights of each role in billing process but also fulfill the development of technology. (2) Each service requester (or provider) is attached to a billing gateway, in this way we can build a "whole network " and implement "connect in one place, access everywhere". (3) The implementation of this scheme extends and encapsulates Web Services protocols, avoids establishing new technology architecture. (4) Not only the feasibility of thescheme is considered, but also a business operating model and the application scene of software service billing are provided.Finally, implementation of billing based on Web Services are investigated. Some advices such as how to build the gateway, the adoption of the SOAP header and how to define custom protocol based on complex type are also given in this paper. Primary experiments suggest that this scheme is feasible and effective, which can be used for reference in further research.
