Migrates from one process to another

JADE JADE by Telecom ItaliaTelecom Italia Java Agent DEvelopment Framework JADA is a software Framework fully implemented in Java language. It simplifies the implementation of multi-agent systems through a middle-ware that complies with the FIPA specifications and through a set of graphical tools that supports the debugging and deployment phases.

T HE R UN - DOWN Mobile Agents are used to transport code in the form of private messages from client to server and vice versa. JADE is a Java platform/framework which allows mobile agents to be securely pass among the platform. JADE has many features such as cross-platform meshing, dummy agent sniffing and introspecting, and multithreaded agents. The framework is simple and one can easily see JADE’s place in the distributed computing schema.
