Abstract: A method for storing of at least one dataset in a distributed data processing network includes: sending, from a specific network node to all close network nodes, an ADD message for adding a value to a dataset, wherein the ADD message comprises the key of the dataset and the value to be added; based on a close network node receiving the ADD message and the key not being known to the close network node, creating a new dataset in an internal table of the close network node comprising the key and the value; and based on the close network node receiving the ADD message and the key being known to the close network node, adding the value to the one or more values in the dataset of the key in the internal table of the close network.

Abstract: A method for transport of messages includes: based on relay-flag information being set to the first value, sending a message directly from a sending network node to a receiving network node, and sending an acknowledgement message directly from the receiving network node to the sending network node; based on relay-flag information being set to the second value, relaying a message from the sending network node via a third network node to the receiving network node, and sending an acknowledgement message directly from the receiving network node to the sending network node; and based on relay-flag information being set to the third value, relaying a message from the sending network node via a third network node to the receiving network node, and relaying an acknowledgement message from the receiving network node via the third network node to the sending network node.

Abstract: A method for distributed service management includes; running, by client nodes and service provider nodes, respective instances of a distributed service management unit, wherein the distributed service management unit comprises a distributed hash set table (DHST); providing, by the distributed service management unit, an application programming interface (API), wherein all connections between a client node and a service provider node are tunneled through the API; registering, by a service provider, a service on a network node; storing, by the registering network node, an endpoint of the service in a dataset of the DHST with a key corresponding to the service; requesting, by the client node, the service; and returning, by the distributed service management unit, all endpoints stored in the DHST with the key corresponding to the service.
