摘要： Apparatus and methods for mitigating network attacks, such as by dynamically re-routing traffic. Various disclosed embodiments manipulate path-based routing of the backbone network to insert a scrubbing appliance within the backbone network topology, rather than using traditional network addressed tunnels in the edge network. In one implementation, traffic entering the backbone network ingress peer routers (from either another backbone network, or an edge network) is normally destination-address routed via the backbone to its appropriate egress router based on a path label; however, when a Distributed Denial of Service (DDoS) attack is detected, the ingress peer router inserts an additional hop into the path label that redirects dirty traffic to a substantially centralized scrubbing appliance. The benefits of the disclosed solutions include, among other things, significantly reduced attack response/recovery times without significant capital outlays.

摘要： Methods and apparatus for resolving resource contention in a content distribution network. In one embodiment, a manager entity at a subscriber premises manages requests for content from various subscriber devices in communication therewith. The manager identifies when there is a conflict, and implements a mechanism to resolve the conflict, such as by determining whether one or more conflicting content items may be provided according to an alternate delivery scheme. In one variant, the apparatus may further implement one or more rules for determining whether to adjust delivery of requested content. In another variant, the disclosed concepts may be utilized to provide efficient delivery of content, by providing alternate delivery prior when doing so would be more efficient than allowing for delivery at a first scheduled date/time. The system may take into account bandwidth or network constraints, whether other requests are pending (although there are still sufficient resources), etc.
摘要翻译：解决内容分发网络资源争用的方法和装置。在一个实施例中，订户房屋处的管理实体对来自与其通信的各种订户设备的内容的请求进行管理。管理者识别何时发生冲突，并且实现解决冲突的机制，例如通过确定是否可以根据备选递送方案提供一个或多个冲突内容项目。在一个变型中，该装置还可以实现用于确定是否调整所请求内容的传递的一个或多个规则。在另一个变型中，所公开的概念可以用于提供内容的有效传递，通过在这样做时提供替代传递将比在第一预定日期/时间允许传送更有效。系统可能会考虑带宽或网络限制，无论其他请求是否处于待定状态（尽管仍然有足够的资源）等。
