MobilityService

• provides two operations
• launchAgent
• cloneAgent
• manages all Grid communication for the
  operations
• converts agent to GMAML form

D'Agents System
EMAA System
NOMADS System

• Grid-enabled Java 2 program
• reconstructs agent from the GMAML form
• executes the agent using supplied launcher
• can be run standalone or as part of an agent
  system
• able to serve a single host or an entire network

Lessons Learned

• Bean-like agent self-description through GMAML
  metadata is a powerful means of supporting
  interoperability.
• Two approaches are required to integrate a
  richly diverse set of mobile-agent systems
  definition of APIs where possible, and clear
  specification of the necessary interactions
  between the systems. Also, a reference
  implementation was very helpful.
• Interaction between developers of disparate
  agent systems led to increased flexibility of the
  mobility API specification.
