FastScan

FastScan is a rate adaptation algorithm for ABR video streaming.

Note that you need to run bandwidth shaping to shape the bandwidth according to your traces in a separate script.

We would like to acknowledge Xiaoqi Yin who provided us with the base code that includes dash.js, their proposed rate adaptation scheme described in their paper "A Control-Theoretic Approach for Dynamic Adaptive Video Streaming over HTTP", and other rate adaptation schemes.

We modified the AbrController.js to include our rate adaptation scheme (FastScan).
The implementation can be found in dash_player/app/js/streaming/algo/bfAlgo.js.

For details, refer to our paper "FastScan: Robust Low-Complexity Rate Adaptation Algorithm for Video Streaming over HTTP", which can be cited as follows:
