Information flow in nowadays networks spreads in the exponential way. This fact is caused by the intensive changes in the Internet communication paradigms. Transmission in the Internet evolved from the simple one-to-one communication to the more sophisticated data exchange methods. In this paper, the authors concentrate on many-to-many (m2m) communication, that is mainly driven by growing popularity of on-line conferences and telepresence applications. We propose several ILP models concerning different videoconferencing schemes. Moreover, proposed models are based both on overlay and joint scenarios. We formulate an overlay model where m2m flows are optimally established on top of a given set of network routes and a joint model where the network routes and the m2m flows are jointly optimized. Each model is being followed by a comprehensive description and is based on real teleconference system.
