Professors Avi Silberschatz, Y. Richard Yang, and Ph.D. candidate Haiyong Xie in Yale’s Department of Computer Science are part of a research team that is proposing an architecture called P4P — which stands for “provider portal for P2P applications†— to allow explicit and seamless communications between ISPs and P2P applications.

The P4P will both reduce the cost to ISPs and improve the performance of P2P applications according to a paper to be presented at ACM SIGCOMM 2008, a premier computer networking conference in August 2008 in Seattle.

According to Silberschatz, current P2P information exchange schemes are “network-oblivious†and use intricate protocols for tapping the bandwidth of participating users to help move data. He says, “The existing schemes are often both inefficient and costly — like dialing long-distance to call your neighbor, and both of you paying for the call.â€
