Based On The Jbi Specification Ern Research Of Distributed Enterprise Service Bus (esb)

Enterprise Service Bus, ESB, because of its support for multiple transport protocols,providing cross-platform data exchange as an excellent data integration, exchange tool widelyused in large-scale SOA systems. The environmental disposal and nuclear terrorist attacksemergency projects by China’s Ministry of Environmental Protection also adopt this technol-ogy.In view of the rapid development of China’s civilian nuclear industry, nuclear radiationmonitoring scale will gradually expand more dispersed and the location of each operating unitcharacteristics, found the centralized ESB may not be able to meet their development needs.In order to respond to such opportunities and challenges, this paper presents a design ap-proach based the ERN (ESB Relation Network) model of Distributed Enterprise Service Bus.The method developed ERN model on the basis of this model., and made modeling for ESBcontrol class exchange information,and develop out of data exchange specification XMLSchema for ERN model. Thus, ERN model and the JBI specification, respectively, to ensurethe unity of the structure of internal data exchange between the ESB and the ESB.First of all, in order to improve the efficiency of the ESB link exchange network conver-gence to reduce the amount of information transfer link between ESB node and narrow thelink message passing range, ERN model proposed the swap area is divided into a backbonearea and a number of non-backbone area management methods. The method is to reduce theERN model coupling relationship between the region and an important foundation for mul-ti-regional link-state parallel computing conditions.Secondly, in order to complete the distributed ESB model infrastructure function basedon switched network proposed link-state generation algorithm and routing rules generationalgorithm. Link-state generation algorithm is used to the ESB nodes collect network informa-tion and generates a switching network link status.The routing rule generation algorithm is used the ESB node in accordance with the link information to generate the next hop addressof the forwarded message.Third, in order to make the ERN model has the ability of adaptive network changes,proposed method to use the ESB state word management the ESB nodes running state andmake the appropriate adjustments in accordance with the changes of network conditions onthe node ESB status word, so use the ESB state word control ESB node plays an significantcontribution to establish an open ESB switched network.Finally, in order to improve the availability of distributed ESB, user rule routing solutionwas proposed for distributed ESB based on the original model, the method of access rules toconduct a mapping and Web services, message sending end and the receiving end betweendecoupled. In addition, the combination of XPath technology implementing message copy,separation, consolidation, and other functions, improve the ability to deal with complex busi-ness exchange network and improve the efficiency of forward.
