The economics of network neutrality
研究了在网络拥堵时，内容提供商向互联网服务商支付额外费用以优先传输内容的私人和社会影响，并推导出网络中立性优于任何可行优先服务方案的条件。
Under the current regime for Internet access, “network neutrality,” parties are billed only by the Internet service provider (ISP) through which they connect to the Internet; pricing is not contingent on the content being transmitted. Recently, ISPs have proposed that content and applications providers pay them additional fees for accessing the ISPs’ residential clients, as well as fees to prioritize certain content. We analyze the private and social implications of such fees when the network is congested and more traffic implies greater delays. We derive conditions under which network neutrality would be welfare superior to any feasible scheme for prioritizing service.
