File sizes have grown tremendously over the past years for music/video applications and the trend is still growing. As a result, large ISPs are facing increasing demand for bandwidth from the growth of file sizes. A main contribution to this bandwidth demand problem is inefficient use of bandwidth due to many ISP customers downloading the same large files multiple times. This paper first reports real experiments conducted on Carleton's Internet backbone by using the large file caching technique. Various cache replacement algorithms are then simulated and compared using traces of large file transfers. The results reveal that least recently used (LRU) performs better than others.
