Abstract: Presented herein are techniques for obtaining pertinent information from a network upon detection of an anomaly by receiving, at a first network node, configuration information sufficient to establish a data collection policy for the network node, capturing data, on the first network node, in accordance with the data collection policy to obtain captured data, detecting an anomaly occurring with respect to a second network node, and in response to detecting the anomaly, in transferring from the first network node, to an analysis server, collected data derived from the captured data based on both the data collection policy and a proximity metric indicating a logical distance between the first network node and the second network node.

Abstract: In one embodiment, a computing device maintains a component list of a plurality of measurable computer network characteristics for a plurality of computer networks, and assigns a component weighting factor to each characteristic within the component list. The computing device may then adjust the component weighting factor within the component list for each particular characteristic over time based at least in part on a measurable effect that particular network characteristic has over one or more of the plurality of computer networks in response to a change to that particular characteristic.

Abstract: An improved technique for distributing routing information that allows routes to be prioritized such that information associated with higher priority routes is sent in update messages ahead of information associated with lower priority routes, thereby enabling the higher priority routes to converge faster than the lower priority routes. In the preferred embodiment of the invention a route policy map that associates routes with priorities is defined. The policy map is then applied to the routes to prioritize the routes. Update messages are then generated using the priority information and the route information contained in the update messages is organized such that route information associated with higher priority routes is placed ahead of route information associated with lower priority routes.

Abstract: A given router in the core of a label-switching network identifies a group of routers to receive common label binding information for later routing packets along respective paths through the label-switching network. One way to identify which of multiple routers to include as a member of the group to receive the same label information is to analyze egress policies associated with downstream routers in the label-switching network. Based on this analysis, the given router identifies group members as routers having a substantially same egress policy as each other. The given router then allocates memory resources to store a common set of label information to be distributed to each member in the group of routers having the same egress policy. After populating the memory resources with label information, the given router distributes a common set of label information to each router in the group of routers.
