NTT Boosts Japan-U.S. Backbone to 300 Gbps

NTT Communications has boosted the backbone capacity of its Global IP Network between the United States and Japan to 300 Gbps.

The company said growing use of broadband and the rising popularity of video content has created a huge demand for trans-Pacific connectivity. When it launched its Global IP Network in 1997, the company relied on a 45 Mbps link to support international Internet access for Japanese ISPs. In 2000, the acquisition of Verio and its Tier-1 IP backbone enabled NTT Com to dramatically raise its U.S.-Japan bandwidth to 1 Gbps. A year later NTT Com introduced network service level agreements (SLA) to provide the highest level of service 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, the network's data transmission speed was 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 by measuring network-latency variability with a jitter-type SLA (also introduced for IPv6 in July 2009). The NTT Com Global IP Network clearly proved its reliability in December 2006, when the network was rerouted with minimal delay following a destructive undersea earthquake off Taiwan. In 2008, the company introduced a traffic analysis system to help IP network operators monitor network traffic to detect and report traffic anomalies.
