Automated registration of one or more IoT devices seeking connection to one or more IoT platforms using a secure provisioning service. The secured provisioning service verifies and administers connection credentials to each IoT device, ensuring legitimate devices cannot be impersonated or controlled by unauthorized personnel. The provisioning service matches the IoT devices and metadata of each IoT device to the provisioning rules. Connection credentials and/or rules defining each IoT device's access to IoT platforms are based on the provisioning rules of the rules registry. Matching each IoT device to one or more provisioning rules offers flexibility to dynamically add, delete or amend one or more rules in a complex rules-based system, allowing for automatic updates to the connection credentials of each IoT device, wherein each IoT device can be provisioned or re-provisioned using the most up to date set of new or amended rules.

A method and system for message subscription management is presented. In one embodiment, the method includes sending a subscription request from a subscriber to a publisher. The subscription request is intercepted and redirected to a broker. Upon intercepting the subscription request, additional information, which includes an instruction to send event messages to the subscriber, is added to the subscription request and forwarded to the broker.

System and method for subscription management in a messaging system

An apparatus and system are disclosed for implementing service qualifiers that define on-demand management requirements for a loosely coupled software service in a service component architecture (SCA) for an integration server by associating a service qualifier with one or more of an SCA service reference, an SCA wire, an SCA interface, or an SCA implementation based on an SCA component definition, requiring the integration server to augment an implementation execution for the SCA service to honor the service qualifier; and accepting user modification and definition of declarative service qualifiers. By allowing the association of service qualifiers with SCA service references, SCA wires, SCA interfaces, and SCA implementations, additional quality of service with which components are executed can be maintained.

Apparatus, system, and method for service component qualifiers for the declarative specification of quality of service

Provided are a method, system, and article of manufacture, wherein a client component including at least one client interface is provided. Also provided is a target component including at least one service interface, wherein the at least one client interface is capable of matching the at least one service interface. A service interface implementation corresponding to the at least one service interface is provided, wherein the service interface implementation is a dynamic service interface implementation. The dynamic service interface implementation is executed to allow access to the client component to a service provided by the target component.

Method, system, and article of manufacture for providing service components

Provided are a method, system, and program for generating asynchronous interfaces and methods from synchronous interfaces and methods receiving a synchronous interface to a target component having a synchronous method used by a client component to synchronously invoke the target component. An asynchronous interface is generated for the synchronous interface of the target component. An asynchronous method is generated for the generated asynchronous interface having arguments to invoke the target component, wherein the client calls the generated asynchronous method to cause an asynchronous execution of the synchronous method.

Generating asynchronous interfaces and methods from synchronous interfaces and methods

A system and method for messaging subscription management by subscribing a subscriber to a publisher, providing a broker brokering message flow between the publisher and the subscriber whereby the publisher publishes information to the broker which then forwards the information to the subscriber, and filtering messages whereby any messages not originating from the publisher are filtered out. The filtering may comprise modifying at the publisher a filter supplied by the subscriber and sending the modified filter to the broker, or may comprise modifying at the subscriber a filter and sending the modified filter to the broker.

A method and computer program product is provided for sending a persistent message in a transaction-enabled messaging and queuing system. A message queue manager is responsible for transferring messages from a sender program to a receiving program via a message queue. A message is sent from the sender program to the message queue manager. The message is defined to permit the message queue manager to select whether to treat the message transactionally or non-transactionally.

Persistent messaging in a transaction processing environment

Provided is a gateway for linking between different communication models. The gateway, which may be implemented in a computer program installable on a server system, facilitates interoperation between computer programs which require synchronous communications sessions and computer programs based on an asynchronous model of communication. The invention enables a synchronously-connected client to revisit interactions with a server and asynchronously communicating programs, to interleave interactions with more than one application, and to associate together request-response pairs of a long running application. In particular, the invention provides apparatus and methods enabling linking between the Internet WWW service and a general purpose messaging system.

Gateway for converting synchronous client/server protocols into asynchronous messaging protocols and storing session state information at the client

A data conferencing network comprises multiple nodes linked together by a communications path. Each node has a copy of a shared data set, which is being updated by the users of the data conferencing network. Updates generated by a user at any particular node are added to a first queue at that node. A permit-token having an associated permit number circulates around all the nodes. When in possession of the permit token, a node can broadcast an update from its first queue. In doing so, it associates the current permit number with the update (to give an update level), and then increments the permit number by one before forwarding the permit token to the next node in its circulation route. Updates received at a node are placed into a second queue. Each receiving node maintains a current update level, representing the most recent update number applied to the shared data set at that node. The second queue is searched for the update having an update level, which exceeds the current update level by one unit. This update is then taken from the queue and applied to the shared data set, and the current update level is accordingly incremented by one unit.

Method and apparatus for the serialization of updates in a data

A method and apparatus for automatically changing the display in overlapping rectangular viewport areas of a display screen of a digital display apparatus and in which each viewport area is assigned a different priority level. The method includes the steps of (a) storing in a random access store indications of the position and size of each viewport area, together with an indication of the priority level of the viewport area and (b) constructing a first matrix of (2n+1).sup.2 elements, where n is equal to the number of viewport areas, by assigning a vertical component to each vertical coordinate of each viewport area and a horizontal component to each horizontal coordinate of each viewport area, and for each element so formed storing an indication of the highest priority level of the viewports falling within the boundary formed by the coordinates defining the element.
