The networks created on the basis of the IP protocol have become more and more interesting for users and network operators / service providers, in terms of their possibilities to support the most diverse communications applications. This perspective is also reinforced by the experience gained over the long period of use of the most widespread public IP network, the Internet, which has proven that it can successfully support/implement/develop the most diverse applications through this technology. Thus, in addition to the traditional, native applications of IP-based networks, those supporting data transmission of any kind, this kind of networks have started to be used more and more often for voice communications (VoIP), IP-based telephony) and video (videophone, video conference, etc.). More than that, IP networks have started to implement remote control and control applications, and the development of communication security technologies has even allowed the realization of transactional applications that involve the transmission of secrets through the environment represented by public IP-based networks (electronic trade, online banking applications, electronic voting through public IP networks, etc.). It presents the key factors that influence the quality of the service, as perceived by the user (the delay introduced by the network when transporting IP packets, the delay variation, the loss of information), also stating the performance requirements of various telecommunication applications that can be supported by public IP-based networks (audio applications, video applications, data applications, non-interactive applications). Performance targets are also presented here which, once achieved, allow the support, under quality conditions, of various types of applications.
