Nowadays, we observe rapid growth of multimedia transmissions in the Internet. Multimedia are typically carried out using the RTP protocol, while the rest of Internet traffic is transmitted via the TCP protocol. In the paper the problem of coexistence of elastic and inelastic traffic is presented. In contrast to other papers, which analyze this issue as the problem of TCP-unfriendliness of the RTP protocol, we focus on this coexistence from multimedia point of view.
