Server Collaboration
• Supports distributed computing applications in which network devices participate– router to router
– server to router
• Supports Intelligent Agents
• Supports Mobile Agents

Active Network Management
• Download Oplet Service to the device.
• Monitor MIB variables • Might be complex conditions• Trend analysis• DiffServ, RMON-II, etc… MIBs
• Report “events” to NMS – drop rate, packets/second
• Allow Service to take action• Download application • Adjust parameters based on
direction from NMS

Complex Condition Exceeded
NMS
No more polling
router
Extensive access to internal resources
Diagnostic Mobile Agents
• Automatic trace-route from edge router where problem exists.– Each node reached generates a report to NMS
– Trace-route code “moves” to next node in path
– Mobile agents identify router health
– Create logs for NMS
Active Intrusion Detection
• Intruder is identified by Intrusion Detection software• Intruder signature is identified• Mobile agent is dispatched in direction of intruder
(based on physical port of entry)• Mobile agent “chases” intruder and terminates him
(shuts down link, reboot host, notify NMS)
