SAE International JAUS Core Service Set AS5710

This document defines a set of standard application layer interfaces called JAUS Core Services . JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Core Services represent the infrastructure commonly found across all domains and types of unmanned systems. At present, seven services are defined in this document: \u25cb Transport Service: Abstracts the functionality of the underlying communication transport layer \u25cb Events Service: Establishes a publish/subscribe mechanism for automatic messaging \u25cb Access Control: Manages preemptable exclusive control for safety critical operations \u25cb Management: Defines component life-cycle management \u25cb Time: Allows clients to query and set the system time for the component \u25cb Liveness: Provides a means to maintain connection liveness between communicating components \u25cb Discovery: Governs automatic discovery of remote entities and their capabilities Each service is described by a JAUS Service Definition (JSD) which specifies the message set and protocol required for compliance. Each JSD is fully compliant with the JAUS Service Interface Definition Language [JSIDL].
