DDoS or Distributed Denial of Service is currently the world’s most costly cyber crime, able to cripple a network for a period of time by using multiple computers that have been infected to send out bogus traffic to a specified target. To mitigate this massive network threat, IP-Converge has partnered with Prolexic Technologies (USA), the world’s pioneer in DDoS Mitigation services.

Prolexic routes traffic via three primary methods (although due to clients individual needs, set-ups are often customized and/or combined):

DNS Redirection / Proxy Our original delivery method and still the quickest method to deploy Prolexic's solution, IPs on Prolexic's intrusion prevention network (IPN) are provided to the customer. Through a DNS change, all customer traffic is routed to Prolexic's IPN, where it is cleansed. Once traffic is filtered of malicious content, it is proxied back to the customer's infrastructure. Proxy is a simple configuration and provides the additional benefit of content caching.

BGP Routing / GRE Tunneling Clean Pipe Virtual Transport can be easily implemented over a dedicated GRE tunnel. Prolexic will announce the customer's subnet and tunnel traffic to its location via Generic Route Encapsulation (GRE) tunnels. GRE tunneling provides a customer several advantages, including total control over when traffic is filtered. Traffic re-routes can be performed quickly using BGP, the standard routing protocol in use today to support complex routing policies.

Direct Circuit Imagine having a dedicated circuit that can withstand a 10+ Gbps SYN flood or TCP connection flood. With dedicated circuits, customers will have the defenses required to survive such attacks without notice. Clean Pipe Virtual Transport?circuits can be implemented like a standard BGP4-enabled Internet circuit. Connections can be made directly within Prolexic’s points-of-presence, or via a Prolexic partnered low-cost dedicated circuit directly to Prolexic’s IPN.

Leveraging on these unique filtering techniques, high-speed bandwidth and peering, advanced routing, and other patent-pending devices, Prolexic has created the most powerful DDoS detection and protection system in the world. For more information, visit www.prolexic.com
