JADE is a Java-based software framework that simplifies the implementation of multi-agent systems and complies with FIPA specifications. It provides agent communication through message passing using FIPA ACL. JADE includes agent platforms, management components, and message transport protocols. Integration with JESS allows reasoning capabilities.

Java Agent DEvelopment Framework JADE g913838 曾文駒
Introduction • JADE • is a software framework fully implemented in Java language. • simplifies the implementation of multi-agent systems through a middle-ware that claims to comply with the FIPA specifications. • is free software (under LGPL) and is distributed by TILAB.
Agent • A computational process that implements the autonomous, communicating functionality of an application. • All agent communication is performed through message passing, where FIPA ACL is the language to represent messages. • All agent have an Agent Identifier (AID).
Message Transport Protocol (MTP) • Three possible message transport protocol: • Internet Inter-ORB Protocol (IIOP) • Wireless Application Protocol (WAP) • HyperText Transmission Protocol (HTTP)
Agent Platform (AP) • An AP provides the physical infrastructure in which agents can be deployed. • An AP consists of the machine(s), operating system, agent support software, FIPA agent management components (DF, AMS and MTS) and agents.
Agent Platform (cont.) • The agent platform can be distributed on several hosts. • Only one Java application, and therefore only one Java Virtual Machine (JVM), is executed on each host.
Agent Management Reference Model (cont.) • Agent • Agent Platform (AP) • Directory Facilitator (DF) • Agent Management System (AMS) • Message Transport Service (MTS) • Software
Integration with JESS • JADE offers also a so-called JessBehaviour that allows full integration with JESS • JADE provides the shell of the agent and guarantees the FIPA compliance • JESS is the engine of the agent that performs all the necessary reasoning
Simple App. ─ ThanksAgent • When Born • registers with the DF • creates two child agents • each of this new agents registers with the DF • If • the father agent sends a message of greeting to the child agent • Then • it waits for an answer to the greeting • it thanks the agents that have answered
