Abstract

This paper deals with the design and implementation of networking support into presentation system. The analysis of the available presentation systems and possible sending techniques led us to the conclusion, that multicast is the best choice for implementing real-time one-to-many communication. The new system was designed to increase delivery reliability missing in UDP protocol, which is the most commonly used for multicast addressing. This system allows application to receive presentation updates made by presenter even if there are short network failures and updating packets are not received immediately. Such a communication makes it possible to share thoughts in real-time without the need for the participants to be located in the same place.
