Benefits of technology

[0027] Due to the large volume of GET commands that may be received, a database function may be performed on the received GET commands to determine if the GET commands are duplicates. The database function may include a hashing algorithm applied to the GET commands to speed processing and to use less memory.

Problems solved by technology

However, a preferred embodiment does not necessarily differentiate between client and server computers in detecting and mitigating the overload condition.

The processor discards further received requests that are determined to be substantially duplicate.

Description

CROSS REFERENCE TO RELATED DOCUMENTS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 956,721, filed Oct. 1, 2004.FIELD OF THE INVENTION [0002] This invention relates to a system and method for preventing distributed denial of service (DDoS) attacks, or the like, via a network, such as the Internet. In particular, the invention relates to a data cleaning center having attack detection and / or mitigation modules that provide DDoS attack-free data to back-end servers. BACKGROUND OF THE INVENTION [0003] During the past few decades, the Internet has provided a convenient way to obtain a wealth of information on almost any subject. Many paid and free information services may be offered over the Internet, including electronic mail, home shopping, gaming, paperless billing services, and the like. Users merely need to obtain a web page address or uniform resource locator (URL) for the service they desire. [0004] In this regard, commercial revenue for I...
