Abstract: Controlled node configuration includes managing a plurality of configurations of a plurality of controlled nodes using a cloud controller. Additionally, controlled node configuration not only monitors inconsistencies if any, present in the plurality of configurations of the controlled nodes but also sends the plurality of managed configurations to them.

Abstract: A controller detects that an agent of a first node managed by the controller is unavailable, the agent providing a service accessible by a tenant of a cloud infrastructure that includes the controller and a plurality of nodes managed by the controller. In response to the detecting, the controller reschedules the service on a second node managed by the controller to continue to provide availability of the service to the tenant. As part of the rescheduling, cooperate, by the controller, with the first node to avoid duplication of the service on multiple nodes including the first and second nodes.

Abstract: The present invention provides an optimization tool that utilizes traffic data across collision domain boundaries to provide suggestions as to how the network should be changed to achieve an optimal network topology. The optimization tool identifies collision domains that are reaching their peak capacity and analyzes their traffic pattern data to determine whether these over utilized collision domain should be divided into smaller collision domains. Once traffic data is collected, the steps typically implemented by the optimization algorithm to determine the optimal network topology include: identifying and removing global talkers from the analysis; creating workgroups based on the network traffic patterns; for each workgroup, deleting any nodes that do not reside on the same collision domain as the rest of the nodes in that workgroup; analyzing the workgroups of each collision domain; inserting previously removed global talkers back into the analysis; and analyzing the global talkers.
