NTT Com's Japan-U.S. Backbone Bandwidth Reaches 600 Gbps

TOKYO, December 19, 2011 /PRNewswire/ --

NTT Communications Corporation (NTT Com) announced on December 19 that it has expanded the data-transmission capacity of its Global IP Network between Japan and the United States to an industry-leading 600 gigabits per second (Gbps). The new capacity, equivalent to approximately 35,000 channels of digital terrestrial television or more than five centuries' worth of content in a daily newspaper, further enhances the company's leadership in Tier-1 trans-Pacific IP connectivity.

NTT Com's global IP backbones are connected to fixed and mobile telecom companies, Internet service providers (ISPs), data center operators and content providers, enabling customers to meet their growing needs for Internet capacity between Japan and the United States. Although a part of the cable was damaged following the March 2011 earthquake, it was quickly repaired with minimum disconnection. This was thanks to the fully redundant cable structure and collaborative efforts with multiple carriers and cable companies, based on an established cooperative relationship. The network, which is IPv4 and IPv6 dual-stuck, is one of NTT Com's core IPv6 networks.

Demand for high-capacity bandwidth has been growing rapidly in recent years, reflected in the seven-fold increase in NTT Com's Japan-U.S. bandwidth between 2005 and 2010. This latest jump - from 500 Gbps to 600 Gbps in just four months - aims to cater to even stronger demand being generated in today's cloud-computing, micro-blogging, social network and online media-intensive environment.

NTT Com Global IP Network Background

NTT Com launched the precursor of its current Global IP Network Service with a 45 megabits per second (Mbps) service in 1997. U.S.-Japan bandwidth was dramatically increased to 1 Gbps when the company acquired Verio and its Tier-1 IP backbone in 2000. NTT Com became the first network provider to measure network-latency variability with a jitter-type service level agreement (SLA) in 2005. The reliability of the NTT Com Global IP Network was capably demonstrated in December 2006, when network traffic was rerouted with minimal delay following a destructive undersea earthquake off Taiwan. In 2008, the company introduced a traffic-analysis system that monitors network traffic to detect and report traffic anomalies to IP network operators.
