The ever increasing demand of internet usage has given rise to many issues like internet application management, bandwidth utilization, protocols mechanism management and, etc. But the Quality of Service (QoS) has become the hottest issue among these issues. Over the past several years, a considerable amount of research work has been done in the field of QoS support for distributed multimedia applications. Most of the work related to QoS support is done at the level of individual architectural layers and a less progress has been made to address the overall end-to-end support for multimedia traffic. A number of research groups proposed the development of QoS architectures across all layers. This paper presents a state of the art survey of QoS architectures.
