Demand
• Clearly there is a demand to address operational issues which are extremely hard to solve from outside the Network(hard = inaccurate, time- or resource-consuming, otherwise expensive)
• Often such issues arise when operating
– managed services (ie CPE based services)
– large managed infrastructures (ie MPLS VPN, Aggregation)
– mobile networks (ie pWLAN aboard trains & buses)
Research
• Significant amount of research work(ICAC, SelfMan itself are proof of that – Passion & Dedication)
Toward Self-Managed networks?
Great Progress – 1/2

msec Sampling
Implementations
• Existing infrastructure => (Event-MIB, Expression-MIB, IOS EEM, RMON, Netconf/E-DI, ...)
• Existing smart data sources available=> (IOS BQA/Corvil, IPSLA, IPFIX/NetFlow, RMON, MIBs, etc ...)

Challenges
• Bridge the Chasm
Need to educate/evangelize on autonomic concepts
Need to link autonomic approaches with the outside world(ie.: synch with external applications, dominant in today's operations, provide transparency)
• (Speed of) Industry Adoption
Need to map research findings onto existing infrastructure
Need to leverage existing (today often under-utilized) data sources better

Opportunities
• Focused Solutions based on matching:
– Demand
– Autonomic approaches
– Existing device instrumentation
• Programmatic Interfaces to Groups of Network Elements lend themselves very nicely to link autonomic approaches with the outside world=> (such as IETF Netconf / Cisco E-DI)
