    • A system architecture for thwarting denial of service attacks on a victim data center is described. The system includes a first plurality of data monitors that monitor network traffic flow through the network. The first plurality of monitors is disposed at a second plurality of points in the network. The system includes a central controller that receives data from the plurality of monitors, over a hardened, redundant network. The central controller analyzes network traffic statistics to identify malicious network traffic. In one embodiment, a gateway device is disposed to pass network packets between the network and the victim site. The gateway includes a computing device executing a process to build a histogram for any attribute or function of an attribute of network packets and a process to determine if the values of the attribute exceed normal, threshold values expected for the attribute to indicate an attack on the site.
    • 描述了用于阻止对受害者数据中心的拒绝服务攻击的系统架构。 该系统包括第一多个数据监视器,其监视通过网络的网络业务流。 第一多个监视器被布置在网络中的第二多个点处。 该系统包括通过硬化的冗余网络从多个监视器接收数据的中央控制器。 中央控制器分析网络流量统计信息,识别恶意网络流量。 在一个实施例中,设置网关设备以在网络和受害者站点之间传递网络分组。 网关包括执行用于为网络分组的属性的任何属性或功能建立直方图的过程的计算设备和确定属性的值是否超过正常的过程,该属性预期的指示对 现场。
