摘要： A method and apparatus are disclosed for dynamically reducing clock skew among various nodes on an integrated circuit. The disclosed clock skew reduction technique dynamically estimates the clock delay to each node and inserts a corresponding delay for each node such that the clock signals arriving at each node are all in phase with a global clock (or 180° out of phase). Delays attributable to both the wire RC delays and the clock buffer delays are addressed. A feedback path for the clock signal associated with each node allows the round trip travel time of the clock signal to be estimated. When the length of the feedback path matches the length of the primary clock path, the clock skew present at the corresponding node can be estimated as fifty percent (50%) of the round trip delay time. Dynamic adjustments to the delay control circuit are permitted as operating conditions shift. Clock signals arriving at individual nodes on the integrated circuit remain in phase with the global PLL clock (PCK), regardless of variations in the operating voltage or temperature (or both).

摘要： A network routing and service control design enables an internet protocol (“IP”) network to effectively divert, on-demand, a given set of IP traffic flow from its normally followed network path to a network-attached application service processing complex and then enable the IP network to re-inject post-processed (e.g., Distributed Denial of Service scrubbed) traffic back into the network for routing to an originally-intended destination. This design also provides a sophisticated control mechanism for application service providers and/or customers/users for service management purposes. For example, application service providers can manage network and service processing resources and customers/users can manage their service requests.
摘要翻译：网络路由和服务控制设计使得互联网协议（“IP”）网络可以根据需要有效地将给定的一组IP流量流从其正常跟随的网络路径转移到网络连接的应用服务处理复合体，然后启用 IP网络将后处理（例如，分布式拒绝服务擦除）业务重新注入到网络中以路由到原始目的地。该设计还为应用服务提供商和/或客户/用户提供了一个复杂的控制机制，用于服务管理。例如，应用服务提供商可以管理网络和服务处理资源，客户/用户可以管理他们的服务请求。

摘要： A method and apparatus for providing traffic management for distributed denial of service (DDOS) traffic. Within a communications network, a DDOS detection system monitors network traffic to identify traffic that is designed to attack a particular server within the network and their entry points into the network. A traffic routing control unit is requested to deny service to the DDOS traffic. By selectively manipulating the routing information propagated to network edge routers, the traffic that is denied service is limited to mostly DDOS traffic and is routed to a cleaning center or a null address in the most effective fashion.
摘要翻译：一种用于为分散式拒绝服务（DDOS）流量提供流量管理的方法和装置。在通信网络中，DDOS检测系统监视网络流量以识别旨在攻击网络内的特定服务器及其进入网络的流量。请求流量路由控制单元拒绝对DDOS流量的服务。通过选择性地操纵传播到网络边缘路由器的路由信息，被拒绝服务的流量主要被限制在DDOS流量中，并以最有效的方式被路由到清洁中心或空地址。
