ARPA research played a central role in launching the “Information Revolution,” including developing or furthering much of the conceptual basis for ARPANET, a pioneering network for sharing digital resources among geographically separated computers. Its initial demonstration in 1969 led to the Internet, whose world-changing consequences unfold on a daily basis today. A seminal step in this sequence took place in 1968 when ARPA contracted BBN Technologies to build the first routers, which one year later enabled ARPANET to become operational.
The United States military is heavily dependent on networked communication to fulfill its missions. The wide-area network (WAN) infrastructure that supports this communication is vulnerable to a wide range of failures and cyber attacks that can severely impair connectivity and mission effectiveness at critical junctures. Examples include inadvertent or malicious misconfiguration of network devices, hardware and software failures, extended delays in Internet Protocol (IP) route convergence, denial of service (DoS) flooding attacks, and a variety of control-plane and data-plane attacks resulting from malicious code embedded within network devices.
The threat of distributed denial of service (DDoS) attacks has been well-recognized in the data networking world for two decades. Such attacks are orchestrated by sets of networked hosts that collectively act to disrupt or deny access to information, communications or computing capabilities, generally by exhausting critical resources such as bandwidth, processor capacity or memory of targeted resources.
