Research of enterprise application integration based-on ESB

Enterprise Service Bus (ESB) is a kind of SOA-based software infrastructure for business application integration. In this paper, it firstly analyses the current state of enterprise integration and the drawbacks of the hub-and-spoke topology, then it introduces a new design approach for EAI base on ESB called EAI-ESB. The EAI-ESB approach which contains Message construction, Messaging channels, Listener, Decryptor, Validator, Enricher, Transformer and Router eight steps ensures consistent and validated data will be routed throughout the ESB between several applications. HTTP Binding SOAP message is one of important decisions in the EAI-ESB approach. At last we summarize the advantages of the EAI-ESB approach and conclude EAI-ESB approach is one of the efficient ways to implement enterprise application integrations.
