Data Stream And P2P Technology

The concept of the data flow was raised a long time ago, but the current market level data-flow products missing, and the industry's demand for such products is also growing, including my effectiveness of the work - China Unicom , is also gradually introduce such products to meet the needs of the company.At the same time, as the popularity of P2P technology, we P2P networks to bring us the benefits are increasingly apparent, therefore developing a P2P-based data stream products is very necessary. This paper is based on such a demand, for example to order tickets for discussion.This paper analyzes the work flow and P2P on the status quo, related concepts and technologies, and on a peer-to-peer suitable for process definition language. Made in the establishment of a P2P topology architecture with the characteristics of a loosely coupled framework of the work flow system, and its internal architecture composed of various functional modules between the communications, information processing management systems in areas such as research Design.Design of the system at all levels and functional modules, its structure and its communication function to optimize studied how users interact with the system, and the point of how the exchange of information between such. System will be integrated into a Java-based MOTION foundation class libraries, on the design of the system functions were tested.In this paper the characteristics of P2P Loosely Coupled with the work flow system, using a flight booking system clear case of the main tenets. And based on JAVA MOTION a foundation class library to achieve the experimental system, a detailed description of the system implementation of the different steps, how users interact with the system, and the point of how the exchange of information, the system proved effective sexual. The study has certain academic and practical value.At present, P2P computing is the main areas of innovation; organization of inter-agency work is becoming a distributed system flow on the main areas at the same time, the functions of the Internet with mobile devices the rapid growth of the demand for small clients and the use of limited bandwidth.These factors together via the Internet to promote the dynamic process of the work flow process. This paper presents the characteristics of a loosely coupled framework of the work flow system, its internal architecture composed of various functional modules between the communications, information processing management systems in areas such as research and design, have a certain academic and practical value.The writer believes that the following aspects can be further study and design future focus: In this paper, and so on all the points are assumed to be recognized, trusted, and will not be facing business workflow applications usually faced by the credit, security , integrity and confidentiality, and other important aspects. The need for data encryption, security, transaction integrity and work flow to do further research, including document encryption in order to maintain the privacy of personal information and digital signatures to provide authenticity. Description of the process also need to provide mapping information for further study, a detailed description of text and graphics tasks, and their dependence essential, but also the definition of the relevant documents.Quality of Service attributes need to be further improved. Apart from the cost and duration of these attributes, the system should also be able to provide participants Based on the mathematical statistics from quality standards. Another option is functional classification, so that the process has been used to assess the coordinator of the task quality, as a member of the tasks assigned to work at the base of decision-making.
