Abstract: Generally described, systems and methods are provided for detecting the impact of network failures. The system collects performance information from a plurality of nodes and links in a network, aggregates the collected performance information across paths in the network, processes the aggregated performance information for detecting failures on the paths, adjusts the set of performance information by removing the performance information for any nodes considered to be associated with performance information that is statistically different from performance information from other nodes at a given location or extrapolates the collected information to other paths, and determines the impact to customers of the network failures detected using the adjusted set of performance information.

Abstract: Techniques for dynamic augmentation of server rack network capacity are provided herein. Network nodes are described that are connected between server rack switches and a rack aggregation layer device. A port allocation controller is also described that can automatically reconfigure the network nodes to create connections, via the network nodes, between the rack aggregation layer device and the server rack switches. These network node connections can be used to alter the network capacities of the server rack switches in response to changing network demands.
