Video streaming is nowadays the dominant Internet application contributing to most of the generated IP traffic. In the 5G era, network slicing and dynamic management can lead to link changes due to handover for offloading and/or optimization purposes, making bottleneck bandwidth and experienced latency varying over time. In this framework, satellite can play a role for an efficient backhauling in several challenging scenarios. Therefore, Adaptive Bit-Rate (ABR) capability in the streaming applications is of paramount importance not only to face up network load variations (usual design requirement), but also to take into account physical changes. This paper aims to investigate performance of two MPEG-DASH ABR algorithms, which mainly cover the main adaptation approaches (throughput-based and buffer-based), on simulated scenarios stressing the link change events and introducing at least a satellite link. The overall performance analysis leverages on the Network Simulator NS-3.

Abstract

Video streaming is nowadays the dominant Internet application contributing to most of the generated IP traffic. In the 5G era, network slicing and dynamic management can lead to link changes due to handover for offloading and/or optimization purposes, making bottleneck bandwidth and experienced latency varying over time. In this framework, satellite can play a role for an efficient backhauling in several challenging scenarios. Therefore, Adaptive Bit-Rate (ABR) capability in the streaming applications is of paramount importance not only to face up network load variations (usual design requirement), but also to take into account physical changes. This paper aims to investigate performance of two MPEG-DASH ABR algorithms, which mainly cover the main adaptation approaches (throughput-based and buffer-based), on simulated scenarios stressing the link change events and introducing at least a satellite link. The overall performance analysis leverages on the Network Simulator NS-3.
