This paper proposed a di#erential service model based on Game Theory. P2P system that implements this model can eliminate free riding and provide predictable level of service. Such predictable level of service is the following: 1. System that implements this model will eventually operate on Nash equilibrium. 2. There existing a critical benefit value b c . When b i , which is the benefit that a peer P i can get from the system, is larger than b c , P i would like to join the system, then operate at the Nash equilibrium value of contribution. If b i c , the peer is better leaving or not joining the system. When b i = b c , the peer is indi#erent between these two options

I was asked, as a computer scientist, to give a sense of what computer technologies the VOF can design for over the next decade. In designing the VOF we need to think in terms of how much storage, bandwidth, and processing power we will have five and ten years from now – because that is the equipment we will actually be using. The good news is that processing, storage, and networking are improving at an exponential pace. In the limit, they are infinitely fast and capacious, and cost nothing. Unfortunately, most of us do not live in the limit; we live in the present so computers will not be free anytime soon. The bad news is that people are getting more expensive, and indeed the management and programming costs routinely exceed hardware costs. If everything gets better at the same rate, then noting really changes, but some ratios are changing. The people:computer ratio is changing so that we now try to minimize people costs. Although computers are getting faster, the speed of light is not changing (so if you want to get data from the other coast, you must wait 60 milliseconds (request-response round-trip time)). In addition, WAN costs have not improved much in the last decade. This is a surprise: the cost of WAN networking is much reduced. But, it seems costs and prices are not correlated in the telecommunications industry. Perhaps this will change in the future, but
