Abstract: A production host includes a persistent storage and a backup manager. The persistent storage stores virtual machine data and a service group list associated with an application service group. The backup manager obtains a backup generation request for the application service group that includes virtual machines, and each of the virtual machines uses a copy of the virtual machine data; in response to obtaining the backup generation request: identifies a first virtual machine the virtual machines that is prioritized for generating a backup for the application service group based on the service group list; attempts to generate the backup using the first virtual machine and the copy of the virtual machine data; and stores the backup in backup storage.

Abstract: A backup storage includes a persistent storage and a backup manager. The persistent storage stores backups of entities and a global application data map. The backup manager obtains a restoration request for restoration of an application hosted by an entity of the entities; makes a determination to accelerate the restoration based, at least in part, on the application; in response to the determination: identifies a virtual disk level backup of the entity that is associated with the application using the global application data map; obtains the virtual disk level backup from the backups of the entities; and restores the application using the virtual disk level backup.

Abstract: A method for providing an application service to clients includes identifying a failure of the application service that causes the application service to be suspended; in response to identifying the failure: instantiating an instance of an application for providing the application service in a production host; identifying at least one virtual disk level backup that is: associated with the application and is a portion of deduplicated backups; extracting the at least one virtual disk level backup from deduplicated backups to obtain a copy of the at least one virtual disk level backup; identifying application data associated with the application within the copy of the at least one virtual disk level backup; transitioning an application service session for a client of the clients to the instance of the application; and resuming the application service for the client using the instance of the application and the application data.

Abstract: A backup storage includes persistent storage and a backup manager. The persistent storage stores backups of entities and an entity list that lists the entities. The backup manager obtains a restoration availability request from a user; filters the entity list based on an identity of the user to obtain an available entity list; identifies, based on user input obtain based on the available entity list, an entity of the entities; and restores the entity using the backups.

Abstract: A backup storage includes a persistent storage for storing backups of entities and a backup data map. The backup storage also includes a backup manager that obtains a search request for data; obtains at least two data maps associated with at least two of the entities; generates the backup data map using the at least two data maps; searches the backups for the data using the backup data map to identify a copy of the data; and provides the copy of the data in response to the search request.

Abstract: A backup storage includes a persistent storage and a backup manager. The persistent storage stores virtual machine level backups and application level backups. The backup manager obtains a request for a point in time restoration of an application; identifies, based on the application, a virtual machine level backup of the virtual machine level backups that is associated with: a virtual machine that hosted an instance of the application and a first point in time prior to a restoration point in time specified by the request for the point in time restoration; identifies, based on the application, an application level backup of the application level backups that is associated with the restoration point in time; generates a point in time backup using: the identified virtual machine level backup, and the identified application level backup; and services the request using the point in time backup.

Abstract: A method for identifying highly-skewed classes using an imperfect annotation of every instance together with a set of features for all instances. The imperfect annotations designate a plurality of instances as belonging to the target rare class and others to the majority class. First, a classifier is trained on the set of features using the imperfect annotation as supervision, to designate each instance to either the rare class or majority class. A combination of the predictions from the trained classifier and the imperfect annotations is then used to classify each instance to either the rare class or majority class. In particular, an instance is classified to the rare class only when both the trained classifier and the imperfect annotation classify the instance to the rare class. Finally, for each instance assigned as a rare class instance by the combination stage, all instances in its neighborhood are re-classified as either rare class or majority class.

Abstract: A method for managing backups that includes generating a full backup of a database and, after generating the full backup, generating N incremental backups of the database and generating a first differential backup of the database after the N incremental backups have been generated, wherein the first differential backup is generated relative to the full backup.

Abstract: A method for distributing Sigtran connections among signal transfer point (STP) message processors includes providing a connection load balancer as a front end to plural message processors of an STP. The method further includes publishing, by the connection load balancer, an Internet protocol (IP) address to SS7 peers. The method further includes initializing the message processors of the STP to listen on the IP address published by the connection load balancer. The method further includes receiving, at the connection load balancer, a Sigtran message addressed to the IP address. The method further includes determining, by the connection load balancer, whether the Sigtran message is an initial message for a Sigtran connection or a subsequent message for a Sigtran connection and whether the Sigtran connection has been assigned to one of the message processors.

Abstract: In one aspect, A computerized method of a gateway distributing routes learned through routing protocols (RP) into a Border Gateway Protocol (BGP) includes the step of providing a first gateway that receives a route over a routing protocol. The method includes the step of with the first gateway, redistributing the route to one or more peer routers as a BGP route based on one or more specified criteria. The method includes the step of setting a gateway precedence based on the redistribution of the route to the one or more peer routers as the BGP route. The method includes the step of, based on the gateway precedence, setting a second gateway to automatically redistribute the route with different priorities to influence steering of traffic to a preferred gateway.

Abstract: A method for authenticating a mobility management entity (MME) for outbound roaming subscribers includes maintaining a Diameter authentication information request (AIR)/update location request (ULR) mapping database at a Diameter edge agent (DEA). A Diameter AIR message is received at the DEA. The DEA determines that the AIR message includes a visited public land mobile network identifier (VPLMN ID) not of record in the database. The DEA records the VPLMN ID in the database. A Diameter ULR message is received at the DEA, and a VPLMN ID is read from the ULR message. The DEA determines that the VPLMN ID read from the ULR message does not match the VPLMN ID recorded for the subscriber in the database. In response to determining that the VPLMN ID does not match the VPLMN ID recorded for the subscriber in the database, the DEA rejects the ULR message.

Abstract: A method and system for SharePoint single web application recovery. Specifically, the method and system disclosed herein overcome the existing problem of data loss that incurs when a SharePoint farm (SPF) (i.e., or more specifically, the configuration database within the SPF) is restored due to the failure of just a single web application that executes therein. The data loss transpires because restoring the SPF leads to the overwriting of data associated with all web applications, and not just the failed web application, that executes on the SPF. The method and system disclosed herein addresses this dilemma through the assembly of web application topology metadata pertinent to recovering any web application periodically prior to a web application failover event, determining that a web application has entered a failed state and, subsequently, triggering and executing the restoration of just the failed web application based on the determining.

Abstract: Embodiments relate to determining whether to take a resource distribution unit (RDU) of a datacenter offline when the RDU becomes faulty. RDUs in a cloud or datacenter supply a resource such as power, network connectivity, and the like to respective sets of hosts that provide computing resources to tenant units such as virtual machines (VMs). When an RDU becomes faulty some of the hosts that it supplies may continue to function and others may become unavailable for various reasons. This can make a decision of whether to take the RDU offline for repair difficult, since in some situations countervailing requirements of the datacenter may be at odds. To decide whether to take an RDU offline, the potential impact on availability of tenant VMs, unused capacity of the datacenter, a number or ratio of unavailable hosts on the RDU, and other factors may be considered to make a balanced decision.

Abstract: A method of identifying land cover includes receiving multi-spectral values for a plurality of locations at a plurality of times. A location is selected and for each time in the plurality of times, a latent representation of the multi-spectral values is determined based on a latent representation of multi-spectral values determined for a previous time and multi-spectral values for the previous time of a plurality of other locations that are near the selected location. The determined latent representation is then used to predict a land cover for the selected location at the time.

Abstract: A method includes receiving data for an entity for each of a plurality of time points. For each of a plurality of time windows that each comprises a respective plurality of time points, a confidence value is determined. The confidence value provides an indication of the degree to which the time window contains data that is useful in discriminating between classes. The confidence values are used to determine a probability of a class and the probability of the class is used to set a predicted class for the entity.
