B/S implementation of internet-based electrical engineering lab with MVC architecture

This paper introduces the B/S (Browser/Server) implementation of iEELab (internet-based Electrical Engineering Lab). Users can login the remote lab using various browsers. Front-end, using Adobe Flex technique, implements network communication from browser to server based on MVC architecture. A middle layer called data exchange layer is extracted, which is the hub of data sending and receiving. The server only transmits data package. This system has good expansibility and new experiment modules can be added easily.
