A SOA-oriented e-learning resource integration infrastructure and its service discovery model

E-learning has been a topic of increasing interest in recent years, meanwhile, the integration of e-learning resource has become a challenge. A robust, manageable, distributed infrastructure is absolutely necessary for e-learning resource integration. This infrastructure at least provides the capability of supporting message-oriented middleware, and event-driven integration, as well as the capability of supporting service routing and substitution, protocol transformations, and other message processing. These requirements are consistent with the principles of SOA. This paper tries to provide a novel SOA-oriented e-learning resource integration infrastructure. In particular, we introduce a novel service discovery model in the context of this e-learning resource integration infrastructure. The initial simulation results show that the model can effectively aggregate the service information and avoid the overload caused by frequent dynamic updating.
