Abstract: In order to achieve the users acceptance requirements and to satisfy some constrains on the multime-dia systems, we need a QoS research. It includes modeling, architecture, traffic management protocols, etc. In these paper topics such as communication model and resource management architecture are analyzed. This al-lows to specify QoS parameters and therefore to control the resource allocation according to the quality desired by application. The adaptation of multimedia QoS to the dynamic operating system and network conditions is important as it allows a better use of resources
