Martin Ellis will present our paper on
Measurements of
Real-Time Traffic to Residential Users at the ACM Multimedia
Systems Conference in San Jose, CA, USA, on 23 February 2011.
Only limited performance data currently exists for streaming high-quality
Internet video to residential users. Data on streaming performance provides
valuable input to the design of new protocols and applications, for example
when evaluating congestion control and error-correction schemes, and for
sizing playout buffers in video receivers. This paper presents measurements
of streaming real-time UDP traffic to a number of residential users, and
discusses the basic characteristics of the data.
The following datasets are referenced from the paper. They contain
measurements of CBR RTP traffic, sent from a campus machine to
receivers connected to the Internet via ADSL and Cable links.
Dataset-A contains only end-to-end measurements, while Dataset-B also
includes some end-to-middle measurements obtained using TTL-limited
probes, and packet-pair measurements from which the path capacities
can be estimated. Dataset-A was collected between June and October
2009, while Dataset-B was collected between April and September 2010.
The raw datasets contain the original trace files logged by our measurement
tools, compressed using crtpdumpz, and traceroute output for each trace (with
IP addresses and hostnames anonymised). The processed datasets contain
end-to-end queueing delay time series (both dataset-A and dataset-B), and
end-to-middle delay measurements and packet-pair capacity measurements
(dataset-B only).
