NTT Communications 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 NTT Communications leadership in Tier-1 trans-Pacific IP connectivity. 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-stack, 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.
