Cross layer design approach for performance evaluation of multimedia contents

Service performance evaluation is usually associated with connectivity related services, such as the provisioning of an Internet connection. Now operators are beginning to explore new business opportunities on the All-over-IP world and beyond. New solutions are being deployed focusing on the multimedia interactive contents. New network architectures will require extensions to provide a clear vision on the service delivery quality, and new approaches on cross-layer information will be envisioned. This paper provides an insight on the cross-layer overview of the current 3 GPP networks, while featuring the analysis until the end-to-end performance and end-user perception. It employs a correlation between the most relevant parameters at each layer and underlines their contribution to the upper layers. It further provides an analytical qualitative analysis of the overall service performance by evaluating simulation results which are sustained by both network and service performance metrics.
