NTT Com Increased Japan-U.S. Backbone Speed surpassing 100 Gbps to Provide the Industry’s Largest Transpacific IP Network

TOKYO, JAPAN ---NTT Communications (NTT Com) announced today that it has significantly increased the U.S.-Japan data transmission speed of its Global IP Network to 100 Gbps, further enhancing the company’s leadership position in Tier 1 transpacific IP connectivity. The increase comes in response to growing customer demand for higher-capacity transmissions between the two countries.

Among carriers with global IP backbones, data traffic between the U.S. and Japan constitutes some of the heaviest volumes in the world. NTT Com’s dedicated capacity is already the highest in the industry between the two countries and the further increased capacity will help to accommodate anticipated growth.

Last year, NTT Com’s increase in bandwidth was equal to its total bandwidth increase during the previous seven years since 1997, the year in which the company launched its service with 45 Mbps to support the international Internet access of Japanese ISPs.

In 2000, NTT Com acquired Verio and its Tier 1 IP backbone, enabling it to dramatically raise its U.S.- Japan bandwidth to 1 Gbps.

In 2001, NTT Com introduced network service level agreements (SLA), ensuring the highest quality in the industry, and in the same year the company expanded its IP backbone to the Rep. of Korea, Hong Kong, Taiwan, Singapore and Australia . In 2002, data transmission speed was further increased to 5 Gbps, or 100 times faster than the 1997 level.

In 2005, NTT Com became the first network provider to enhance its backbone with a jitter-type SLA , which measures the variability of network latency . The NTT Com Global IP Network proved its worth in December 2006 by enabling the network to be smoothly rerouted following its disruption by the Taiwan earthquake.

As a global Tier 1 provider, NTT Com looks forward to continually enhancing its 24/7 high-quality, high-speed data transmission services.
