3. Self-Managing Networks Summit3 What IS an enterprise network anyway? Network is a cost center, business is something else Same company owns infrastructure and end systems Security is important Apps are often more constrained Heterogeneity is common –Data center? Extranet? VPN? External face? –Many different types of devices and systems There is no such thing as a “typical enterprise network”!

4. Self-Managing Networks Summit4 Top sources of cost (1/2) Configuration –Software deployment/installation –Hardware deployment/installation –Testing and certification of new hardware and software Troubleshooting –Intermittent failures –Serialization and disjoint sources of troubleshooting data –Lack of logging standards –Noise in data (too much) –Help desk, telephone support –Attacks and viruses

5. Self-Managing Networks Summit5 Top sources of cost (2/2) In-house apps/tools –Alpha code for in-house business apps –Developing in-house management apps –Lack of sufficient tools motivates in-house apps/tools –Own unique set of problems –Web site and wiki maintenance Training Heterogeneous versions across devices/hosts Extranets, remote access

6. Self-Managing Networks Summit6 Ways to reduce cost Increase resiliency - redundancy and self-adaptation Homogenize Better ways to test and sandbox Better models to understand complexities and dependencies Data consolidation and mining in real-time Proactive monitoring before help desk calls More self-help tools/systems Sharing of problem/workarounds - knowledge base Have a backup system 1 version behind

7. Self-Managing Networks Summit7 Barriers to adoption Pace of change - new technologies, apps, hard for automation to keep up Value proposition for investment –Can savings be quantified? –Short-term (switching cost) vs long-term cost tradeoffs & budgets (CapEx vs OpEx approval) Awareness of tools & best practices, job security

8. Self-Managing Networks Summit8 Next steps for research Study of enterprise attributes for various types of enterprises Highly reliable systems out of homogeneous components at low cost Standard evolvable logging schema to help correlation and aggregation problems What is a “normal” model based on captured data Performance debugging Network aware apps, what is good behavior What-if modeling and sandboxing of complex systems Methodology for interactions between protocols Scalable network emulation
