We just updated a full-length version of PCC to arXiv, but it takes some time for arXiv to process and post online. The full version discussed our approach in a more detail and, I believe, clearer way. We have more evaluation for more challenging network scenarios and also evaluated PCC with different utility functions expressing different data transfer objectives.

So here is a preview: http://web.engr.illinois.edu/~modong2/pcc_fullpaper.pdf During this two weeks, we are writing some simple docs and making the file-transfer SOFTWARE more user-friendly. We also plan to release our experiments/demo CODE so one can easily play with and compare PCC with existing TCP variants.

Code is available at https://github.com/modong/pcc, but currently it is under some refactoring and some compile/run instructions are outdated. We will have a more formal release in two weeks.

Thanks
