TeleGeography Finds Internet Backbones Account for 85% of International Bandwidth

According to the latest statistics published in TeleGeography's Global Internet Geography research service, Internet backbones now account for over 85 percent of the world's cross-border capacity used in fiber-optic networks. The balance of used capacity is dedicated to private corporate networks and international telephone traffic.

The rate of Internet backbone growth varies dramatically by region. Mature Internet markets in the U.S. and Europe have seen relatively slow growth, just 30 to 40 percent over the last year. Asian backbones have upgraded much more rapidly?over 70 percent last year?and show no signs of slowing down.

Despite these growth rates, a huge portion of international fiber-optic bandwidth still goes unused. On trans-Atlantic routes, for example, only about a quarter of currently lit capacity is actively deployed to carry voice, Internet, and corporate traffic. The remainder lies idle, either unsold or unused by service providers. This mismatch of supply and demand could persist for several more years due to the still untapped "upgradeable" capacity of current submarine networks.

The data cited above are excerpted from both Global Internet Geography, a research service focused on Internet backbones, traffic, and pricing, as well as International Bandwidth, TeleGeography's guide to long-haul bandwidth supply and demand.
