Methods and systems for emulating an application include generating a log template to match one or more patterns in a set of application logs collected from an original application. Semantic state representations are learned for the original application from the log template. A classifier is trained to predict a next action template based on a sequence of prior action templates. A regressor is trained to generate a parameter value for a template based on a sequence of prior action templates and a particular semantic state of the original application.

Machine learning to emulate software applications

A network function optimization method, system, and computer program product include optimizing network function chain components of a software by modifying a structure of the network function chain components by removing a function of the network function chain components.

Techniques for power savings in communications equipment are provided. The computer-implemented method can comprise identifying, by an electronic device operatively coupled to a processing unit, one or more connectivity requirements of one or more servers associated with a data center. The computer-implemented method can also comprise determining, by the electronic device, a defined graph that satisfies the one or more connectivity requirements. The computer-implemented method can further comprise powering down, by the electronic device, one or more elements of the data center that are not required by the defined graph; and powering up, by the device one or more nodes of the data center, which are in any state other than power up, that are required by the defined graph.

Method and apparatus for power savings in communications equipment

A computing system for learning a device type and message formats used by a device is provided. The computing system includes an interface and a processor. The interface is receptive of documents describing identification information and communication and application protocols of devices. The processor is coupled with the interface to obtain rules of network packet analysis using document analytics and identify identification information and communication and application protocols of network messages from devices using the rules.

Automatic protocol discovery using text analytics

A network function optimization method, system, and computer program product, include optimizing network function chain components by modifying a structure of the network function chain components by removing one of the functions of the network function chain components in response to a constraint according to a policy requirement.

A method is provided of using a set of servers to provide deferential services that have a pre-negotiated time for notice to release the servers. The method includes defining a virtual checkpoint frame interval that is constrained to a duration of up to half of the pre-negotiated time for notice to release the servers. The method includes, responsive to an end of the interval, (i) writing, to a shared state database, a state of processing of the packets and transactions occurring during the interval that are processed by a current one of the servers, and (ii) releasing the packets and transactions occurring during the interval. The method includes copying the packets and transactions occurring during the interval, and the state, from the current server to another server for subsequent processing, responsive to an indication of an instance loss on the current server.

Synchronized release of resources used in deferential cloud services

According to one embodiment, a method, computer system, and computer program product for ancillary speech generation is provided. The present invention may include receiving a query from a querent; interpreting the terms of the query using schema information; rewriting the initial query into a set of related queries; pruning related queries that are irrelevant based on contemporary circumstances; retrieving preferences associated with the querent, where each of the preferences is assigned a weight representing the importance of that preference to the querent; filtering out the pruned related queries that do not comport with the querent's preferences; sort the filtered related queries according to the weight of the preferences served by each query; answering the filtered related queries with a knowledge graph; returning answers to the querent; and updating the preferences based on the answers.

Ancillary speech generation via query answering in knowledge graphs

A computer program product is provided for fault diagnostics and recovery of network service chains. The product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer to cause the computer to perform a method. The method includes identifying intersecting ones of components of the network service chains in a network graph indicative of a commonality therebetween. The method further includes selectively repairing one or more of the components of at least one of the network service chains up to an entirety thereof based on a component repair sequence that maintains service continuity of the network service chains and that is determined and selectively reordered based on the commonality. The network graph includes a plurality of graphs, each (i) including one or more Virtualized Network Functions, and (ii) corresponding to a respective one of the network service chains.

A computer-implemented method is provided for fault diagnostics and recovery of network service chains. The method includes identifying, by a processor, intersecting ones of components of the network service chains in a network graph indicative of a commonality therebetween. The network graph represents the components of the network service chains. The method further includes selectively repairing, by the processor, one or more of the components of at least one of the network service chains up to an entirety thereof based on a component repair sequence that maintains service continuity of the network service chains and that is determined and selectively reordered based on the commonality. The network graph includes a plurality of graphs, each (i) including one or more Virtualized Network Functions, and (ii) corresponding to a respective one of the network service chains.

A method includes configuring worker services to operate in a stateless manner and providing support services that enable the worker services to operate in the stateless manner. The support services include (i) a management service for providing notifications of server removal and addition, (ii) a state maintenance service for maintaining state information in a central location, and (iii) a load balancer service for distributing requests among worker services. The method includes altering a number of servers allocated to at least one worker service, responsive to a notification from the management service. A private protocol is used between the worker services and load balancer service (a) to send, from the worker services to the load balancer service, a respective pointer to the state information associated with the requests, and (b) to include the respective pointer in the requests when any of the requests are forwarded to any worker service.

Deferential support of request driven cloud services

A method is provided of using a set of servers to provide deferential services that have a pre-negotiated time for notice to release the servers. The method includes defining a virtual checkpoint frame interval that is constrained to a duration of up to half of the pre-negotiated time for notice to release the servers. The method includes collecting packets and transactions occurring during the interval that are processed by a current server. The method includes, responsive to an end of the interval, (i) writing, to a shared state database, a state of processing of the packets and transactions occurring during the interval, and (ii) releasing the packets and transactions occurring during the interval. The method includes copying the packets and transactions occurring during the interval, and the state, from the current server to another server for subsequent processing, responsive to an indication of an instance loss on the current server.

Name based Internet of Things (IoT) discovery includes receiving domain name system (DNS) events. An Internet Protocol (IP) address to name mapping is built based on the DNS events. A data communication event occurring in a computer network is received. A destination IP address in the data communication event is mapped to a domain name by querying the IP address to name mapping. Whether the data communication event is associated with an IoT device is determined based on the domain name satisfying a rule.
