the intelligent online network (iOn) has been designed to leverage the power of the latest technologies and communication infrastructure to empower a forum that enables effective sharing and distribution of knowledge. the system consists of users registered either as clients or experts. A central database is maintained to store all clientele information and archives, and this is used to answer the clients' query if a match is found in the database, using an innovative natural language query-matching method. If no solution could be located in the database archives, the question and list of active experts is submitted to the mobile agent. the agent then traverses the experts online, thus consolidating the solution to be returned to the user. the system makes possible the implementation of disconnected operation mode next-generation networking protocols, while effectively handling load balancing and reliability.

Advances in multimedia computing offer new approaches to support on-line access to information from a variety of sources such as video, audio, images, and transparencies. the key to success in providing distributed real-time retrieval, is the control of network delay and congestion to keep up the desired quality-of-service (QoS). In this paper we present a new distributed multimedia database environment, called NetMedia. this environment can support controlled delivery of video, audio, and text data, across Internet. NetMedia can be the base of various distributed multimedia applications. As an example we present NetMedia-Virtual-Classroom, an asynchronous distance learning tool, which uses the advantages of the NetMedia framework.
