Extending IEEE LTSA e-Learning Framework in Secured SOA Environment
IEEE LTSA framework for e-Learning provides a template that may be used for digital distance learning. However, with the advent of newer and faster communication technologies, the concept of online learning and evaluation came into being. Most of these systems are operating in an environment of distributed system. On-line learning expanded the earlier computer-aided, computer based and other eLearning methodologies, but remained confined to predefined need. Dynamic or on-the-fly customization of different learning services was not possible due to the lack of suitable software architecture. Introduction of Service Oriented Architecture (SOA) proves to be a boon for any web portal based interactive customized application. IEEE LTSA model specifies a high-level architecture for information technology supported learning, education and training systems. It describes high-level system design in an integrated environment. Independent modules may be considered as stand-alone services but interconnected modules may or may not be converted successfully into composite services.This paper presents a step-wise extension of IEEE LTSA e-Learning architecture to a secure Client-Server based model and then to a Distributed System based model with added security features. An extended e-Learning architecture in SOA is proposed, which is capable of providing secured stand alone as well as composite teaching-learning services. The proposed architecture is then tested with a case study of a e-Learning web portal to prove the validity of the proposed extended architecture, which shows enhancement over the present architecture used. It also brings out the viability of e-Learning services in SOA.
