Introduction of a large-volume data (40 Gbps) interface to the backbone network of Yahoo! BB - Improvement in network operability and progress toward an environment where service is provided with better stability -February 20, 2006
SOFTBANK BB Corp. and BB TECHNOLOGY Corp. (Head office: Minato-ku, Tokyo; Representative: Masayoshi Son; hereinafter "SOFTBANK BB" and "BB TECHNOLOGY," respectively) announce the introduction of Cisco Systems K.K.'s OC-768/POS interface, which is capable of handling large-volume data traffic of 40 Gbps, to the backbone network of Yahoo! BB, a comprehensive broadband service. Operations began in January 2006. The new interface was introduced to efficiently respond to an ever-increasing number of broadband users as well as new-coming applications and content geared to broadband services.
The backbone network of Yahoo! BB supports a broadband communications environment for more than 5 million Yahoo! BB users (as of December 31, 2005), various applications and content provided on the network that are compatible with broadband services (e.g., BB Phone, BBTV, BB Soft), and active Internet communications both inside and outside the Yahoo! BB network. With the recent widespread penetration of broadband, the volume of data traffic exchange both inside and outside the Yahoo! BB network is increasing each year. On January 4 of this year, it was confirmed that large volume data traffic exceeding 100 Gbps was exchanged between Yahoo! BB network and the Internet.
Introducing the 40-Gbps interface will allow for large-volume data traffic up to four times larger than what is possible with a conventional 10-Gbps interface, and improve the efficiency and scalability of transmission equipment resources for the Yahoo! BB backbone network. As a result, the network's operability improved and stability in the provision of services is even more enhanced, despite an increase in the number of broadband users.
Additionally, in introducing the OC-768/POS interface which can manage 40-Gbps traffic, Cisco Systems K.K.'s high-end router of next generation-Cisco Carrier Routing System-1-is deployed and the transmission network is provided by JAPAN TELECOM CO., LTD.
Yahoo! BB will continue to provide a high-quality, stable broadband communications environment founded on its backbone network, with higher operability.
