    Abstract: A communications device, such as an Internet-of-Things device, includes an entity resource to originate or consume data, and core resources to facilitate stateless messaging with a remote device, with the messaging being associated with the entity resource. Transaction resources are provided to manage a transaction with the remote device. The transaction includes a sequence of messages associated with the entity resource. The transaction resources include a transaction state machine to represent a current intra-transactional ephemeral state from among a plurality of intra-transactional ephemeral states representing progression of the transaction, a commit handler to institute a persistent state change related to the entity resource in response to a successful completion of the transaction, and a transaction communicator to conduct intra-transaction communications via the core resources directed to corresponding transactional resources of the remote device.

    Abstract: Techniques for implementing a publish-subscribe messaging system are disclosed. An example device generates a topic string comprising a string of characters that represent a subscription to a requested publication. A subscription filter is computed based on the topic string. The device is configured to receive a publication, which includes a data payload and a publication filter. The device performs a bitwise comparison of the subscription filter and the publication filter to determine whether the publication is a destination match for the subscription. If the publication is a destination match for the subscription, the device consumes the data payload of the publication.
