Abstract: An example method involves providing, with a network management module of a network management system, current reroute statistics in a data structure based on the rerouting of the data from a logical circuit that has failed to a logical failover circuit in the network. The current reroute statistics include a committed information rate corresponding to the logical circuit in the network. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. Updated reroute statistics are provided, with the network management module, based on a change in a status of the logical circuit resulting from the committed information rate having been exceeded.

Abstract: Method and apparatus for dynamic Node healing in a Multi-Node environment. A multi-node platform controller hub (MN-PCH) is configured to support multiple nodes through use of dedicated interfaces and components and shared capabilities. Interfaces and components may be configured to be used by respective nodes, or may be configured to support enhanced resiliency as redundant primary and spare interfaces and components. In response to detecting a failing or failing primary interface or component, the MN-PCH automatically performs failover operations to replace the primary with the spare. Moreover, the failover operation is transparent to the operating systems running on the platform's nodes.

Abstract: A management device includes a processor that executes a process. The process includes: saving a conversion table when an information processing apparatus that performs a memory access by the conversion table, in which an active absolute address that is used by the processor to specify data is associated with an active physical address that indicates a storage area in a memory that stores therein the data, has failed; creating a second conversion table in which a standby absolute address that is different from the active absolute address is associated with the active physical address used at the time of a failure and a standby physical address that is different from the active physical address used at the time of the failure is associated with the active absolute address; setting the second conversion table; and acquiring the data from the storage area that is indicated by the physical address.

Abstract: An example method involves generating, without manual intervention, a table to store current reroute statistics based on rerouting of data from a logical circuit that has failed to a logical failover circuit in a network. The current reroute statistics include trap data corresponding to the logical circuit. The trap data includes a committed burst size. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. The table is updated, without manual intervention, to store updated reroute statistics. The updated reroute statistics include updated trap data corresponding to the logical circuit. The updated reroute statistics are based on a change in status of the logical circuit corresponding to a dropped frame when the committed burst size has been exceeded.

Abstract: Intelligent client computing devices track and record the changes they make to data, applications, and services. Systems, devices, and computer readable media for detecting service tier failures and maintaining application services provide a resilient client architecture that allows a client application on an intelligent client to automatically detect the unavailability of server tiers or sites and re-route requests and updates to secondary sites to maintain application services at the client tier in a manner that is transparent to a user. The resilient client architecture understands the level of currentness of secondary sites in order to select the best secondary site and to automatically and transparently bring this secondary site up to date to ensure no data updates are missing from the secondary site.

Abstract: A system, and computer program product for tolerating failures using concurrency in a cluster are provided in the illustrative embodiments. A failure is detected in a first computing node serving an application in a cluster. A subset of actions is selected from a set of actions, the set of actions configured to transfer the serving of the application from the first computing node to a second computing node in the cluster. A waiting period is set for the first computing node. The first computing node is allowed to continue serving the application during the waiting period. During the waiting period, concurrently with the first computing node serving the application, the subset of actions is performed at the second computing node. Responsive to receiving a signal of activity from the first computing node during the waiting period, the concurrent operation of the second computing node is aborted.

Abstract: In one embodiment, a primary root node may detect one or more neighboring root nodes based on information received from a first-hop node and may select a backup root node among the neighboring root nodes. Once selected, the backup root node may send the primary root node a networking identification and a corresponding group mesh key which the primary root node may forward to the first-hop nodes to cause the first-hop nodes to migrate to the backup root node when connectivity to the primary root node fails. In addition, the first-hop root nodes may migrate back to the primary root node when connectivity to the primary root node is restored.
