Updated work on March 1st

During the period of time, I've read lots of research papers which helped a lot on our project.

The articlie is named "P2P network traffic control mechanism based on global evaluation values" published by Xu xiaolong and Wang ruchuan at 2009.

In the article, he gives evaluation about how does the currnet P2P network traffic work and what are the problems. From the evaluation part, it is easy to find that the high priority based peer network traffic could performance better on almost all situations. The author gives a comparasion about the performance between two network traffic.

Thus I think if we use the same idea, our project could be efficient enough for users.
