Simulates a HTTP Adaptive Streaming (HAS) session based on a throughput pattern and video segment sizes.

pydashsim - HAS simulation

Simulates a HTTP Adaptive Streaming (HAS) session based on a throughput pattern and video segment sizes. The simulation is part of the supplemental material to the HASBRAIN scientific paper: https://github.com/csieber/hasbrain

QUICKSTART

You need a traffic pattern and a video to run the simulation:

python3 pydashsim.py -t samples/traffictrace.csv -s samples/segments.csv

Select a specific adaptation logic with -l:

python3 pydashsim.py -l TRDA -t samples/traffictrace.csv -s samples/segments.csv

The simulation output files are placed in the out/ folder by default. Existing files are overwritten!

Adaptation Logics

Logic	Abbreviation	Description
NoAdaptationLogic (default)	NO	Always select lowest quality level.
KLUDCPLogic	KLUDCP	[1] by C. Müller et al.
TRDALogic	TRDA	[2] by K. Miller et al.
NeuralNetworkLogic	NN	[3] by C. Sieber et al.

Usage

usage: pydashsim.py [-h] [-o OPT_DIR] -t TRACE -s SEGMENTS [-l LOGIC] [-v]

Execute the simulation.

optional arguments:
  -h, --help            show this help message and exit
  -o OPT_DIR, --opt_dir OPT_DIR
                        Output folder
  -t TRACE, --trace TRACE
                        Goodput trace to use.
  -s SEGMENTS, --segments SEGMENTS
                        Video to use.
  -l LOGIC, --logic LOGIC
                        Adaptation logic (NO, KLUDCP, TRDA)
  -v, --verbose         Enable debug log.
