Abstract
The inability of current Internet-based learning systems to deal with different kinds of learners and the high cost of developing a new learning system are well-known problems in e-learning. To overcome these problems, we have designed a learning middleware suite, called the Collaborative and Sharable Learning (CoSL) system. CoSL is a tool set for building e-learning systems and for developing course materials for an e-learning environment. Given the geographic distribution of the components of a Web-based e-learning system, it is crucial to support fast communication between providers and consumers of e-learning course materials. In this paper, a high performance Publisher/Subscriber communication system has been designed for real-time communication between participants. CoSL allows us to build and manage global real-time learning systems in a distributed and heterogeneous environment.
