This paper presents video traffic sources specification and analyses at IP layer. The aim is to analyze network segments with video services that tend to congest the channels and find proper configuration parameters in order to avoid overflow. The authors analyze the Quality of Service (QoS) and Network Performance requirements in wired and wireless LAN as well as 3G network. Measurements and simulations in different network domains help to obtain the presented data. Special attention is paid to networks with video streaming and interactive video services. QoS of heterogeneous sessions is analyzed.
