Agents
Allowing programs to move autonomously
about a network in order to access remote
resources

•
Migrate to servers -> access data or computational
resources -> migrate again -> return to home base
Benefits

•
•
•
Disconnection is easily supported
Access to large amount of data to solve problem
Allow the functionality of servers to be expanded
dynamically
