Abstract: In one embodiment, a device detects a denial-of-service attack and generates a message in response to the detection of the denial-of-service attack. The message is then virally distributed to a plurality of subscribed devices.

Abstract: In one embodiment, a node N, within a computer network that utilizes a directed acyclic graph (DAG) to route packets, may select a parent node P that is a parent to the node N in the DAG. The node N may determine a grandparent node GP within the computer network that is a parent of the parent node P in the DAG. The node N may select an alternate parent node P′ within the computer network that has connectivity to the grandparent node GP and the node N. A sibling connection may be established within the computer network between the parent node P and the alternate parent node P′. The sibling connection may provide a path for reaching prefixes reachable via the node N.

Abstract translation: 在一个实施例中，利用有向非循环图（DAG）来路由分组的计算机网络内的节点N可以选择作为DAG中的节点N的父节点的父节点P. 节点N可以确定作为DAG中的父节点P的父节点的计算机网络内的祖父节点GP。 节点N可以在计算机网络内选择与祖父节点GP和节点N连接的备用父节点P'。可以在计算机网络内在父节点P和备用父节点P'之间建立兄弟连接， 。 兄弟连接可以提供用于到达可通过节点N到达的前缀的路径。
