Embodiment Construction

[0019] The present invention relates to the Internet-of-Things (IoT) IoT infrastructure, where multiple IoT network users (such as IoT sensors, actuators, wireless transmitters / receivers, etc.) A component such as, for example, a host that provides network services communicates. The communication of sensors, actuators and / or wireless transmitters / receivers with the network and with hosts in the network is based on the IP protocol. Optionally, IoT network users (IoT sensors / actuators and / or wireless transmitters / receivers) can act as hosts. For example, a user of an IoT network finds the associated network service by means of DNS-SD via mDNS (Domain Name System Service Discovery via Multicast Domain Name System, see standard: IETF RFC 6762). IoT network users need web services so that they can communicate and can transfer data or measurements to the web services. The web service is in turn used to receive it and optionally control or transmit instructions to IoT network users...

Abstract

The invention relates to a method for identifying a network service (210-230) in a network (300), which has at least one Internet of Things network user, in particular an Internet of Things sensor / actuator (100), via a multicast domain name system mDNS on the basis of domain name system service discovery, DNS-SD. Requirements (1) conforming to Domain Name System Service Discovery, DNS-SD, for a network service type (11) are sent by an Internet of Things network user (100, 210, 220, 230) to a network (300) having at least one host providing a network service. At least one domain name system service discovery (DNS)-SD compliant reply (2, 3) of one of the hosts is received for the request (1). The reply (2, 3) has a textbox with web service indicia (12). A connection request (4) is sent by an Internet of Things network user (100) to a host (210-230) that is associated with a network service flag (12) and that provides a desired network service.

Description

technical field [0001] The invention relates to a method for identifying network services in a network with Internet of Things network users. Background technique [0002] In the field of Internet-of-Things (IoT), typically, network users (such as sensors and / or actuators) are connected to the network via cables or wirelessly in order to allow communication with services in the network. Communication between network users (eg sensors and / or actuators) and services in the network can be based on the IP protocol, for example. The search for services in the network can take place, for example, via Domain Name System DNS-based service discovery according to the standard IETF RFC6763. IoT network users (eg sensors / actuators) are typically configured such that they can communicate with fixed network services. When the address of the web service changes, all connected IoT sensors / actuators have to be reconfigured, which results in a considerable effort every time the address of t...
