觉得核心服务集

This document defines a set of standard application layer 2x 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, eight services are defined in this document:Transport Service: Abstracts the functionality of the underlying communication transport layerEvents Service: Establishes a publish/subscribe mechanism for automatic messagingAccess Control: Manages preemptable exclusive control for safety critical operationsManagement: Defines component life-cycle managementTime: Allows clients to query and set the system time for the componentLiveness: Provides a means to maintain connection liveness between communicating componentsDiscovery: Governs automatic discovery of remote entities and their capabilitiesList Manager: Encompasses behavior common to doubly linked listsEach 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 ].Cross Reference: AIR5665,AS5669,AS5684,RA33P1,RA33P2,RA33P3
