Abstract
The proposed paper focuses in outlining the implementation of online laboratories within the framework of the iLab Shared Architecture (ISA) in order to facilitate sharing those labs among several institutions and managing laboratory users. The laboratories are compliant with the ISA batched architecture, which is based on Web services to mediate the communication between Lab Servers and Lab Clients. The first laboratory presented is a Hybrid Lab that allows for the realization of real experiments as well as simulations with an analog programmable device.
Highlights
Using online laboratories has the potential of significantly reducing obstacles related to cost, time-inefficient use of facilities, inadequate technical support and limited access to laboratories
This work is focused on the iLab Shared Architecture (ISA) Batched experiments and proposes the implementation of two different online laboratories within this framework
The client communicates with the READ lab server and is delivered as a Java Applet, as this is a type of client supported by the iLab shared architecture
Summary
Using online laboratories has the potential of significantly reducing obstacles related to cost, time-inefficient use of facilities, inadequate technical support and limited access to laboratories. The course of the execution can be changed at any time by the user Due to their differences on the implementation, operation and technical requirements, a different architecture (ISA) exists for each one of them, the iLab team at the MIT has already released a merged architecture in August 2008 (Fig. 1). This work is focused on the ISA Batched experiments and proposes the implementation of two different online laboratories within this framework In this architecture the communication between clients and laboratory is mediated by a middleware server (Service Broker), a Web application that manages users’ accounts, data storage and can provide different clients with access to several different lab servers in a “many to several” mode and delegates to experiment server only the experiment execution. That means that clients and lab servers can be developed in any platform supporting Web services
