Telecommunications

Although most Americans are familiar with Internet service providers that give consumers a pathway, or "on-ramp," to the Internet, few are familiar with Internet backbone providers and backbone networks. At the Internet's core are many high-capacity, long-haul "backbone" networks that route data traffic over long distances using high-speed fiber lines. Internet backbone providers compete in the marketplace and cooperate in the exchange of data traffic. The cooperative exchange of traffic among backbone providers is essential if the Internet is to remain a seamless and widely accessible public medium. Interconnection among Internet backbone providers varies both in terms of the physical structure and financial agreements of data traffic exchange. The physical structure of interconnection takes two forms: (1) the exchange of traffic among many backbone providers at a "network access point"--a common facility--and (2) the exchange of traffic between two or more backbone providers at "private" interconnection points. No publicly available data exist with which to evaluate competitiveness in the Internet backbone market. Evolution of this market is likely to be largely affected by two types of emerging services. First, demand is likely to rise for time-sensitive applications, such as Internet voice systems. Second, more "broadband"--bandwidth-sensitive--content, such as video, will likely flow over the Internet in the coming years.
