P4P Aims to Solve Bandwidth Challenges

P4P Aims to Solve Bandwidth Challenges

Two professors from the University of Washington and Yale University, presenting at a conference in Seattle today, describe a new and faster data transfer technology across the Internet. Professors Arvind Krishnamurthy and Richard Yang believe their technology offers a better solution to current challenges facing broadband providers.

Their algorithm, called P4P or "local file-sharing," finds the shortest path across the Internet by tracking users' locations—improving both, download speeds by about 20% as well as bandwidth requirements.

The following is an abstract from today's discussion:

As peer-to-peer (P2P) emerges as a major paradigm for scalable network application design, it also exposes significant new challenges in achieving efficient and fair utilization of Internet network resources. Being largely network-oblivious, many P2P applications may lead to inefficient network resource usage and/or low application performance. In this paper, we propose a simple architecture called P4P to allow for more effective cooperative traffic control between applications and network providers. We conducted extensive simulations and real-life experiments on the Internet to demonstrate the feasibility and effectiveness of P4P. Our experiments demonstrated that P4P either improves or maintains the same level of application performance of native P2P applications, while, at the same time, it substantially reduces network provider cost compared with either native or latency-based localized P2P applications.
