Communications in SPADE are handled internally by means of the Jabber protocol.

• Agent Communication Channel (ACC)
• An Agent Management System (AMS)
  • A way for the agents to be registered in the platform and to be reachable for contact.
• Directory Facilitator (DF)
  • Kind of public service in which agents publish the services they offer

FIPA-compliant

• Agent Communication Language (ACL)
  • Common language for all agents to communicate with
  • In a flavor of clear, practical syntax based on XML

XMPP

• Extensible Messaging and Presence Protocol (XMPP)
  • Open, XML-inspired protocol for near-real-time, extensible instant messaging (IM) and presence information
• SPADE is the first to base its roots on the XMPP technology

SPADE Agent Library

• Collection of Python classes, functions and tools for creating new SPADE agents

SPADE Agent Model

• Every agent has Jabber ID (JID) and a valid password to establish a connection with the platform.

  e.g. myagent@myprovider.com

• Each SPADE agent has an internal message dispatcher component

Predefined Agent behaviors

• A behavior is a task that an agent can execute using repeating patterns:

  • Cyclic and Periodic behaviours are useful for performing repetitive tasks

  • One-Shot and Time-Out behaviors can be used to perform casual tasks

  • The Finite State Machine allows more complex behaviors to be built

  • Event behaviors respond to some event that the agent perceives
