The present disclosure relates to systems and methods for providing cloud-based services securely to on-premises networks or other infrastructure. More particularly, the present disclosure relates to systems and methods for enriching first-party data (e.g., data collected directly by an on-premises server) stored within on-premises networks by enabling the on-premises networks to retrieve and process third-party data stored on cloud-based networks. As a technical benefit, cloud-based services can be performed on the first-party data within the on-premises networks.

A method includes identifying, by a first instance of a service, a first number of data partitions of a data source to be processed by the service and a second number of instances of the service available to process the first number of data partitions. The method further includes separating the first number of data partitions into a first set of data partitions and a second set of data partitions in view of the second number of instances of the service, determining a target number of data partitions from the first set of data partitions to be claimed by each of the second number of instances of the service, and claiming, by the first instance of the service, the target number of data partitions from the first set of data partitions and up to one data partition from the second set of data partitions.

Self-replicating management services for distributed computing architectures are provided herein. An example method includes providing one or more nodes providing services; and maintaining a quorum of a plurality of management servers by: providing a distributed coordination service for the one or more nodes on each of the plurality of management servers; managing, via a director, requests for data on the distributed coordination service from the one or more nodes; promoting at least one of the one or more nodes to being one of the plurality of management servers; and maintaining secure tunnels between the plurality of management servers and the one or more nodes.

Certain embodiments generally relate to mobile communications networks, such as, but not limited to, the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Long Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE-A, and/or future mobile network technologies, such as, for example 5th Generation (5G). A method may include detecting, at a mobile network entity, that context information pertaining to a mobile terminal has changed. The method may also include publishing updated context information through implementation of a publish/subscribe mechanism.

Described are methods, systems and computer readable media for performance logging of complex query operations.

A system for numeric pattern normalization for cryptographic signatures is provided. The system includes a resolving client, and an at least one signature server. The at least one signature server includes at least one processor and non-transitory computer readable media having encoded thereon computer software comprising a set of instructions executable by the at least one processor. The set of instructions may be executed by the signature server to generate a message to be transmitted to a resolving client, normalize the message via numeric pattern normalization, generate a hash value for the normalized message, and generate a cryptographic signature based on the hash value. The signature server may then generate a signed message having the message signed with the cryptographic signature, and transmit the signed message to the resolving client.

Techniques are described for automatic discovery of two or more virtual service instances configured to apply a given service to a packet in a software-defined networking (SDN)/network functions virtualization (NFV) environment. Virtual service instances may be deployed as virtual entities hosted on one or more physical devices to offer individual services or chains of services from a service provider. The use of virtual service instances enables automatic scaling of the services on-demand. The techniques of this disclosure enable automatic discovery by a gateway network device of virtual service instances for a given service as load balancing entities. According to the techniques, the gateway network device automatically updates a load balancing group for the given service to include the discovered virtual service instances on which to load balance traffic for the service. In this way, the disclosed techniques provide auto-scaling and auto-discovery of services in an SDN/NFV environment.

An initial data center is selected to host the online conference. This data center can be selected based on the locations of the participants, a weighting (or ‘priority’) of the participants, or a combination of the two (e.g., locations that are weighted by the participant's priority.) Typically, the data center closest to the centroid (i.e., geometric center, or ‘center of mass’) of the participants is selected. In anticipation that participants will join and/or leaver the conference, a list is calculated that each possible change to a respective data center that will be selected if that change occurs. This list may be distributed to the data centers that, if selected, would host the online conference.

A network arrangement that employs a cache having copies distributed among a plurality of different locations. The cache stores state information for a session with any of the server devices so that it is accessible to at least one other server device. Using this arrangement, when a client device switches from a connection with a first server device to a connection with a second server device, the second server device can retrieve state information from the cache corresponding to the session between the client device and the first server device. The second server device can then use the retrieved state information to accept a session with the client device.
