Toward Self-Managed networks?
Great Progress – 1/2
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 – 2/2
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 ...)
Example: IP SLA
Example: Diagnose MPLS

Toward Self-Managed networks?
Moving Forward – 1/2
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

Toward Self-Managed networks?
Moving Forward – 2/2
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)
