Traffic model for HTTP-based adaptive streaming

2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017
The amount of video traffic on the Internet has seen a tremendous increase over the past few years. In 2020, it is predicted to account for 85% of the total Internet consumer traffic. Due to this dominant role, streaming traffic has to be considered by workload models used to evaluate the performance of networking systems.

Interactions between HTTP adaptive streaming and TCP

Proceedings of the 22nd international workshop on Network and Operating System Support for Digital Audio and Video, 2012
HTTP adaptive streaming (HAS) is quickly becoming a popular mechanism for delivering on-demand video content over the Internet. The chunked transmission and application-layer adaptation create a very different traffic pattern than traditional progressive video downloads where the entire video is downloaded with a single request.In this paper, we ...

A Cumulative Quality Model for HTTP Adaptive Streaming

2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX), 2018
The quality of adaptive streaming may fluctuate strongly during a session. Therefore, a challenge is how to evaluate the quality of a session over time. In this study, a cumulative quality model is proposed for HTTP adaptive streaming. The model is based on the concept of a sliding window of video segments over a session.

Bandwidth estimation and rate adaptation in HTTP streaming

2012 International Conference on Computing, Networking and Communications (ICNC), 2012
HTTP Streaming is one type of video streaming technology, delivering multimedia data using HTTP/TCP. Due to the strict boundaries between layers of the OSI communication model, HTTP Streaming client at the Application Layer can only see the bandwidth that TCP at the Transport Layer supplies.

Modeling live adaptive streaming over HTTP

Computer Communications, 2016
Video streaming methods have evolved greatly over the years. Today, the most prevalent technique to stream live and video on-demand is the adaptive HTTP streaming and is used by several commercial vendors. In this paper, we present an approximate analytic model for live adaptive streaming over HTTP.

Efficient Bandwidth Estimation for HTTP adaptive streaming

The International Conference on Information Networking 2014 (ICOIN2014), 2014
As the multimedia devices are becoming more diverse and the HTTP adaptive streaming techniques grow in popularity, the transmission of adequate video quality becomes increasingly important. HTTP adaptive streaming requires accurate information about available bandwidth of client for quality adaptation.

Dynamic adaptive HTTP streaming of live content

2011 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks, 2011
MPEG has recently released a first public draft of the new Dynamic Adaptive Streaming over HTTP (DASH) specification. The new streaming technique is based on the 3GPP and partly also on the Open IPTV Forum (OIPF) specifications. In this paper, we give an overview about the new DASH specification with a special focus on Live streaming services. In order

DRM protected dynamic adaptive HTTP streaming

Proceedings of the second annual ACM conference on Multimedia systems, 2011
Dynamic adaptive HTTP streaming (DASH) is a new concept for video streaming using consecutive downloads of short video segments. 3GPP has developed the basic DASH standard which is further extended by the Open IPTV Forum (OIPF) and MPEG. In all versions available to date, only very simple content protection use cases are enabled.
