DE-CIX
The DE- CIX is an Internet node in Frankfurt am Main and in terms of throughput of the largest in the world. It is operated by the DE- CIX Management GmbH.
Development
The DE- CIX was founded in 1995, among others, by Arnold Nipper, and was originally a project of three Internet service providers (ISPs ). Took over the business of the Association of the German Internet Industry, now the commercial activities of the DE- CIX were transferred to the DE- CIX Management GmbH, headquartered in Cologne, which is a wholly owned subsidiary of the eco association.
According to information from the DE- CIX handles a large part of the German peering traffic and is connected by ISPs the second and after the largest internet node traffic in the world (as of October 2012). 1999 moved to DE- CIX in a new data center the company Interxion on Hanauer Landstrasse in Frankfurt am Main by, 2012, the technical infrastructure of the DE- CIX a star topology and is a total of 14 data centers (RZ ) the operator e-shelter, Equinix, level (3 ), ITENOS, Interxion, New Telco, TelecityGroup and Telehouse distributed in the city of Frankfurt.
Technology
The distributed switch infrastructure enables ISPs, free exchange data ( " peering "). The connection of the members either via fractional Gigabit Ethernet ( 0.2 Gbps), Gigabit Ethernet, fractional 10 Gigabit Ethernet (2.5 Gbps), 10- Gigabit Ethernet ports or 100 Gigabit Ethernet ports.
In April 2001, DE- CIX 2 went into operation in order to solve the space problems in the old data center and to increase the reliability. The new and the old location were connected by fiber optic cables. The increasing Internet traffic, and the request for additional reliability have made it necessary to take in January 2004, a third DE -CIX nodes in operation, which was installed at the company TelecityGroup in the Gutleutstraße in Frankfurt am Main. In all three locations was the end of 2006 each one of type Cisco Catalyst 6509 - NEB -A Switch. After the switches were replaced by new TeraScale E1200 Force10 and taken at the same time, a fourth DE- CIX node in the Kleyerstraße in operation. The old Cisco hardware has since been used in the also operated by the DE- CIX Management GmbH Hamburg WORK -IX. In Q1 2009, the two Force10 switches of the DE- CIX core network were (formerly Foundry Networks ) is replaced by Brocade MLX -32 switches. In order to further expanding demand, the TeraScale E1200 were replaced by ExaScale Force10 E1200i from the end of 2009. In April 2013, DE- CIX announced the construction of DE- CIX Apollo. This consists of an optical network based on ADVA FSP3000 and Alcatel-Lucent 7950 XRS. The new platform offers 100 Gigabit Ethernet ports and is September 1, 2013, are available.
Locations
The Internet node is housed redundantly in several data centers in Frankfurt am Main. The individual locations are:
Data rate
In August 2013 more than 500 Internet service providers and other organizations from more than 55 countries at the DE- CIX were tethered, including virtually all of the major Internet service providers. Data throughput has exceeded the mark of 2 terabits per second in September 2012 for the first time. According to the website DE -CIX has currently a capacity of 7 Tbit / s
Far less traffic is measurable for the new Internet protocol IPv6. In March 2012, ran an average of only 0.8 Gigabit / s of IPv6 traffic through DE -CIX, which corresponds to 0.088 % of the IPv4 traffic. After World IPv6 Launch Day June 6, 2012 ran at peak times (usually about 21:00 clock ) already 3.5 Gigabit / s by the DE- CIX. In May 2013 to run an average of 8 Gbit / s via the DE- CIX.
The highest ever IPv6 throughput at the DE -CIX was achieved on 1 June 2013, 47.4 Gigabit / s.
