On Tradeoffs Between Cross-ISP P2P Traffic and P2P Streaming Performance Peng Yang, Lisong Xu Department of Computer Science and Engineering University of Nebraska-Lincoln Lincoln, NE 68588-0115 Email: {pyang, xu}@cse.unl.edu Abstract—Peer-to-peer (P2P) technology greatly scales up and media server load. Upload bandwidth is used by peers to traditional Internet streaming service. However, the philosophy distribute video content to one another. Reducing the cross- that peers help one another distribute video content produces ISP P2P traffic may lower the upload bandwidth utilization a large amount of cross-ISP P2P traffic. Newly proposed ISP- friendly P2P mechanisms reduce the cross-ISP P2P traffic by and cause the download rates of some peers to drop below using locality-based peer selection methods with which peers tend their required streaming rates. To maintain smooth playback, to connect to other peers in the same ISP domain. However, one those peers have to download a portion of video content from unanswered question is that how we can achieve the tradeoffs their media servers, which increases the media server load. between the cross-ISP P2P traffic and the P2P streaming per- The pro
