US 2021/0240719 A1 · DATA STREAM ANALYTICS AT SERVICE LAYER

Abstract

A modular and distributed architecture for data stream processing and analysis is described to incorporate data stream analytics capabilities, called Data Stream Analytics Service (DSAS) in the IoT/M2M service layer. Each service layer node hosting DSAS can be split into two independent modules, Stream Forwarder and Stream Analytics Engine. Stream Forwarder is a light weight processing modules that can be responsible for data preprocessing and routing. Stream Analytics Engine is responsible for performing actual analytics on the data stream. Separating the two functionalities enables the service layer nodes to efficiently distribute stream analytics tasks across multiple nodes.

Claims23

Dependent claims

An apparatus for a service layer comprising a processor, a memory and communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:

receiving, from each of a plurality of data sources, a plurality of data streams;
determining each unique data stream in the received plurality of data streams;
filtering each unique data stream, to determine at least one attribute in each unique data stream for use in executing at least one predetermined query;
causing execution of the at least one predetermined query on each filtered unique data stream;
and
sending output of the at least one predetermined query based on at least one predetermined trigger.
