An example operation may include one or more of identifying a workflow specification including a number of entities and state elements, selecting two or more entities designated as a subset of entities among the entities, where the subset of entities share one or more of the state elements of the workflow specification among the state elements, and creating a first smart contract identifying the one or more state elements.

A method, computer program product, and computer system for receiving, at a first node of a plurality of nodes in a distributed architecture, a request for at least one of a device and a service based upon, at least in part, an attribute of at least one of the device and the service. A query to resolve the request may be forwarded to a plurality of nodes in the distributed architecture. A probability of at least a portion of nodes of the plurality of nodes to resolve the query may be determined based upon, at least in part, a search routing mechanism. The request may be forwarded to a second node of at least the portion of nodes of the plurality of nodes based upon, at least in part, the second node having a higher probability to resolve the query than a third node of at least the portion of nodes of the plurality of nodes.

System and method for attribute based device and service discovery

A method, computer program product, and computer system for creating a dynamic directory of objects. A request to modify a dynamic directory of a plurality of objects is received. Each of the plurality of objects is associated with one or more attribute-value pairs. One or more first object attribute-value pairs is determined for a first object. The dynamic directory is searched for the one or more first object attribute-value pairs. A first attribute-value pair is identified from the one or more first object attribute-value pairs. The first attribute-value pair is different than the one or more attribute-value pairs associated with the plurality of objects. The dynamic directory is modified based on the first attribute-value pair. Modifying the dynamic directory includes at least one of adding the first object to the dynamic directory, deleting the first object from the dynamic directory, and modifying an attribute-value pair of the first object.

Systems, methods, apparatuses and program products configured to provide a topology-service tool are described. A presence-federation solution asset is leveraged to address topology-federation problems. A network topology tool takes as input network endpoints, for example caller and callee telephone numbers, determines a network service flow used to connect the network endpoints, and develops a network topology view of the service flow along with associated network device related information.

Systems and methods for service assurance using virtualized federated presence infrastructure

Systems and associated methods for providing scalable presence subscriptions in federated presence environments are described. Embodiments provide for intelligent addition of subscriptions to a presence system. Embodiments identify if a virtualized presentity (corresponding to a new query) can be composed from existing virtualized presentities, and if so, corresponding query processing cells (QPCs) (servicing existing queries) are reused to retrieve the presence information (partially or fully) for the new incoming query. Embodiments organize the existing QPCs into a hierarchy such that a QPC/virtual presentity at a higher layer fetches presence information of all or some presentities from QPCs/virtual presentities at lower layer(s) to service the new query.

Systems and methods for creating scalable presence subscriptions in federated presence environments

A method, an apparatus and an article of manufacture for managing a subscription hierarchy in a presence system. The method includes receiving a presence information request within a presence server, wherein the request is one of a subscription request and an un-subscribe request, determining if the request corresponds to an existing subscriber in the presence server, and if so, sending a redirect message to the existing subscriber, and if not, processing the request within the presence server, and enhancing functionality of subscribers to accept and handle subscription and un-subscribe requests.

A system for enabling communication between multiple cloud-based services operating on a common cloud infrastructure includes a cloud infrastructure providing cloud-based services. The cloud-based services include a first service of a first tenant and a second service of a second tenant. A live directory is located within the cloud infrastructure and aggregates and distributing sharing and availability information pertaining to one or more of the cloud-based services. A back-end network is within the cloud infrastructure and enables communication between the cloud-based services and the live directory. A wide area network enables communication between the cloud-based services and one or more remote clients. The sharing and availability information pertaining to one or more of the cloud-based services aggregated and distributed by the live directory is used to establish a back-end connection between the first service of the first tenant and the second service of a second tenant.

Clustering devices in an Internet of Things ('IoT'), including: receiving, by a device clustering module, a characteristic set for a device, wherein the characteristic set specifies one or more device attributes and an attribute value for each device attribute; clustering, by the device clustering module, the device into an attribute level cluster based on the one or more device attributes specified in the characteristic set for the device; and clustering, by the device clustering module, the device into a value level cluster based on the attribute value for each device attribute, wherein the value level cluster is a subset of the attribute level cluster.

Clustering devices in an internet of things ('IoT')

Methods and arrangements for object identification. An identification request is received from different objects of a network. Attributes and values of each object are ascertained, and at least one attribute-value pair from each object is filtered out. An ID is generated for each object based on at least one remaining attribute-value pair from the filtering.
