II. GII THIU V JADE PLATFORM2. Kin trc Jade :

A JADE-based application is composed of a collection of active componentscalled Agents.

Each agent is a peer and has a unique name. Each running instance of the JADE runtime environment is called aContainer as it can contain several agents. Each agent lives in a Container. The set of active containers is called a Platform. The Platform provides a homogeneous layer that hides to agents the

complexity and the diversity of the underlying tires (h/w, OS)


16/23

II. GII THIU V JADE PLATFORM One container plays the role of a Main Container (where AMS, DF live) to

which all other containers must register as soon as they start. The main container differs from normal containers as it holds two special

agents (automatically started when the main container is launched). Two Special Agents:

The AMS (Agent Management System) that provides the namingservice and represents the authority in the platform.

The DF (Directory Facilitator) that provides a Yellow Pages service bymeans of which an agent can find other agents providing the serviceshe requires in order to achieve his goals.
