Some embodiments of the present invention comprise a method, system, and/or computer program product for a publish/subscribe messaging system. A processor identifies a subscriber of a pub/sub messaging system. The processor retrieves a stored encrypted key for the identified subscriber of the pub/sub messaging system. The processor communicates the retrieved encrypted key to a user selected from a group comprising a publisher of the pub/sub messaging system and the identified subscriber of the pub/sub messaging system. The processor implements end-to-end encryption of messages of the pub/sub messaging system based on key-groups.

Publish/subscribe messaging

A message is sent by a message tracking device to at least one device that is configured to report status of internal processing of content within the message. The reported status of the internal processing of the content within the message by the at least one device is monitored.

Monitoring of subscriber message processing in a publish/subscribe messaging environment

A method and system are provided for transactional messaging support in connected messaging networks. A first messaging network is provided which does not support transactional processing and a second messaging network is provided which does support transactional processing. A proxy application is provided between the first and second messaging networks. The proxy application receives messages from a first application on the first messaging network, the messages including instructions regarding transactional processing of the messages, and forwards the messages to the second messaging network using a transactional processing supported by the second messaging network.

Transactional messaging support in connected messaging networks

A messaging system having a cluster of receiving applications for handling received messages, and a cluster of messaging engines for receiving messages from one or more message sources and forwarding the received messages to one of the receiving applications is provided. Each messaging engine is operable to transmit load balancing information, the load balancing information comprising an indication of the current loading on the messaging engine. The receiving applications are instructed to establish a connection to receive messages from a particular messaging engine within the cluster based on the load balancing information. Accordingly, applications are able to receive messages in such a way that the messages do not build up unprocessed on a particular messaging engine for too long, and such that messages are routed to messaging engines where messages are being consumed, and so that the receiving applications receive messages from every messaging engine where messages are arriving.

Messaging forwarding system and method

A method for managing a plurality of messages associated with an online messaging system is provided. The method may include receiving a message from a messaging source. The method may also include determining whether the messaging source associated with the received message is trusted. The method may further include tagging the received message or storing the received message, wherein the tagging and the storing is based on the determination that the messaging source is not trusted. The method may additionally include validating the received message.

Taint mechanism for messaging system

Embodiments of the present invention provide a method, system and computer program product for configurable pacing in messaging systems. In an embodiment of the invention, a configurable message pacing method has been provided. The method includes receiving a message directed for placement in a repository of an intermediate messaging system into which messages are placed by message producing applications and from which messages are retrieved by message consuming applications. Thereafter, it can be determined if the placement of the received message into the repository will result in a breach of an associated threshold value for the repository. Consequently, a message pacing action can be triggered responsive to the determination that the placement of the received message into the repository will result in a breach of the associated threshold value for the repository.

Configurable pacing for messaging systems

In an embodiment of the invention, a method for wireless power generation for managing power distribution in a wireless environment is provided. The method includes receiving a request from a device to connect to a wireless power distribution base station, authenticating the device, determining a lease period during which time power is to be delivered wirelessly to the device in response to authenticating the device, and delivering power wirelessly from the wireless power distribution base station to the device for the duration of the lease period, but subsequent to the lease period, discontinuing delivery of power wirelessly to the device.

Managing power distribution

A message associated with a subscription topic hosted by a publish/subscribe message tracking device is sent by the publish/subscribe message tracking device to at least one subscriber device that is registered to the subscription topic and configured to report action completion processing based upon content of the message. The action completion processing based upon content of the message by the at least one subscriber device is monitored.

Technique for analyzing memory areas based on local copies of a global counter by: (i) determining a plurality of currently-executing fast threads and a plurality of currently executed slow threads; (ii) intermittently incrementing a global counter variable to have a current global counter value; (iii) intermittently setting the local counter of the data set for each fast thread of the plurality of fast threads to be equal to the current global counter value; (iv) determining that no slow threads of the plurality of slow threads reference the first memory region; (v) assigning a free-after value to the first memory region; (vi) determining whether the free-after value of the first memory region is less than or equal to all of the local counters of the fast thread data sets of the plurality of fast threads; and (vii) de-allocating the first memory region.

Reference counting for memory areas

A message published by a publisher device and associated with a subscription topic hosted by a publish/subscribe message tracking device is received at the publish/subscribe message tracking device. A determination is made to monitor action completion processing of the message by at least one subscriber device. The message is sent to the at least one subscriber device that is registered to the subscription topic and configured to report action completion processing of the message. The action completion processing of the message by the at least one subscriber device is monitored. Monitoring results of the monitored action completion processing are published.

Transactional capable queuing is provided. A queue having an ordered list of messages is provided. A get cursor operation is provided within the queue to point to a current starting place for a getting application to start searching for a message to retrieve. A first lock is provided for putting operations, in response to there being more than one putting application, to ensure only one application is putting to the queue at a time. A second lock is provided for getting operations, in response to there being more than one getting application, to ensure that only one application is getting from the queue at a time. Putting applications and getting applications are synchronized to check and update the get cursor operation.
