A patent has been granted to DE-CIX, the operator of the world’s largest neutral Internet Exchange, headquartered in Frankfurt, Germany, for its new “Blackholing Advanced” service. “Blackholing Advanced” reinforces the defense against DDoS (Distributed Denial-of-Service) attacks directly on Internet Exchanges by using numerous individual filtering mechanisms. The patented mechanism significantly limits malicious traffic at the transport layer and port through fine-grain filtering. 

Free of charge, the new service is now available in a beta version for all DE-CIX customers in Frankfurt, Madrid, and New York. Since its inception, the DE-CIX blackholing feature has been used increasingly, and customers have asked to extend its functionalities. 

While always developing new services based on feedback from customers, DE-CIX jointly developed the product requirements for Blackholing Advanced in a “community workshop”. Considering the increase in DDoS attacks, security is an ongoing focus for the company. The opportunity to fully test a beta version, for the first time, “hopes to receive valuable direct feedback,” said Dr. Thomas King, Chief Technology Officer at DE-CIX. “The patent granted for the innovative filter mechanisms is a reward from our years of research.

“The new service will also be offered as a premium variant in the future. Standard Blackholing Advanced is free of charge for DE-CIX customers and includes numerous preset filters. The high-end Freemium version, which is subject to a fee, also offers flexibly customizable filters that can be activated directly by the customer.”
