YouTube Live is one of the most popular services on Internet, enabling easy streaming a live video with acceptable quality. Thus, understanding user perception this service utmost importance for network operators. As in other services, traffic affected by delays and interruptions due to unfavorable conditions, which translate into unacceptable initial reproduction times, image freezes, or abrupt changes Detecting these events key ensure an adequate quality experience (QoE). Unfortunately,...

Traffic classification will be a key aspect in the operation of future 5G cellular networks, where services very different nature coexist. Unfortunately, data encryption makes this task difficult. To overcome issue, flow-based schemes have been proposed based on payload-independent features extracted from Internet Protocol (IP) traffic flow. However, such an approach relies use expensive probes core network. Alternatively, paper, offline method for encrypted radio interface is presented. The...

Several upcoming 5G and 6G services will rely on unmanned aerial vehicles (UAV) sending live information to remote terminals. Thus, understanding the traffic flows that might influence end-user experience in these is key for cellular network operators. One of UAV-based first person view (FPV) drone control, consisting control UAV Beyond Visual Line Sight scenarios using only video visualized a ground station. This work focuses networking aspects this service by presenting assembly,...

Live video streaming services are gaining momentum as network and terminal capabilities improve. However, 360° live pose new challenges due to its high bandwidth computational requirements both on the user service provider. In this paper, a study of impact uplink cellular performance in YouTube is presented. Unlike previous works, analysis focuses upstream between source server, not downstream server viewers. To end, measurement campaign conducted where feed transmitted received through...

The properties of a web page have strong impact on its overall loading process, including the download contents and their progressive rendering at browser. As consequence, content has experience users. In this paper, we present WebCLUST, clustering-based classification approach for pages, which groups pages into quality-meaningful classes impacting Quality Experience (QoE) Groups are defined based standard Multipurpose Internet Mail Extensions (MIME) breakdown external subdomain connections,...

In multi-hop wireless networks, the way network topology is defined has a strong impact on routing. This paper deals with control in cellular networks relays. Several algorithms taken from ad-hoc are adapted to networks. Most of considered here based proximity graphs. Performance analysis carried out realistic scenario built geographical data live network. Assessment several performance criteria, namely connectivity, energy efficiency, sparseness, adaptability, throughput and interference....

YouTube Live is one of the most popular services on Internet, enabling an easy streaming a live video with acceptable quality. Thus, understanding user´s perception this service utmost importance for network operators. As in other videostreaming services, traffic sometimes affected by delays due to unfavourable conditions, which translate into unacceptable initial reproduction times or image freezes as result client´s buffer underrun. Detecting these events key ensure adequate Quality...

In this paper we provide a new approach to estimate the link usage of multicast reliable transport protocols. It can be used as benchmark evaluate their scalability. We have chosen, case study, protocol called RCCMP. has been designed simple, scalable, and TCP-friendly. The cost is due data, retransmitted characteristic packets protocols such control packets. For RCCMP, are number receivers involved in session. Also, reliability added bandwidth consumption. Simulation results demonstrate...
