P4P(Proactive network Provider Participation for P2P)

P4P(Proactive network Provider Participation for P2P) is the P2P technology to upgrade, strengthen service providers (isps) and client program communication, reduce backbone network transmission pressure and operational costs, and improve improved P2P file transfer performance. And P2P randomly chosen Peer (equivalence machine), P4P agreement can coordinate different data, was able to the topology of the network, so as to improve the effective choice Peer network routing efficiency.

P2P software application engulfed a huge amount of network bandwidth, this makes operators big headache. Verizon engineer had a set of new topological theory P4P algorithm, are likely to reconcile the contradictions technical method.

The traditional P2P mode data nodes and transmission are random, i.e. the transmission method may occupy any network node or export of bandwidth. But P4P is intelligent select data exchange object, more through intelligent computation select the same routers or regional network to exchange data, maximum extent solve large-scale nodes and network outlet through the same intelligent choice load, data exchange object can also greatly improve the data transmission capacity. In Internet advertising, there is also a P4P Pay for performance, is the abbreviations in English. That is to say, let advertisers not according to advertising time to pay, but according to advertising the actual effect, after brings the number of users is practical to pay. This p4p and p2p technology no relationship.

And P2P randomly chosen Peer (equivalence machine), P4P agreement can coordinate different data, was able to the topology of the network, so as to improve the effective choice node network routing efficiency. Still with the above example, the Beijing user can prioritize and Beijing city rivals users to realize file fragment of exchange, then expanded to distant regions, have very necessary, will go abroad document clips exchange. Of course, the operation mechanism, P4P than "city exchange" concept, it will also according to the user's uplink, download bandwidth make comprehensive judgments, for the most effective choice, maximize the overall efficiency of the exchange.

The virgin P4P recoveny is a work of Chinese at Yale university, dr ever jazer. Dr xie of American distributed computing industries federation (DCIA) and P4P group's chief researcher, put forward and completed P4P theory and system design. Since the end of February, xie hai ever since such P4P system design researchers in field test on a large scale.

The Chinese invented the dominant commercial tests in a good performance. According to the feedback, use Verizon P4P technology, P2P users average download speed increased 60%, fiber to the home users increase 205% ~ 665 %. In addition, operators internal data transfer distance reduced 84%. Users have a 58% of data is from city rivals, compared to traditional P2P of 6.3% proportion had nearly 10 times the ascension.
