  1. Managing Enterprise Networks: How do we reduce IT costs? June 2, 2005 Self-Managing Networks Summit

  2. Participants • Hari Balakrishnan • Rebecca Isaacs • Lee Gates • Venkat Padmanabhan • Sunjeev Pandey • Jennifer Rexford • Dave Thaler • Alec Wolman Self-Managing Networks Summit

  3. 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”! Self-Managing Networks Summit

  4. 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 Self-Managing Networks Summit

  5. 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 Self-Managing Networks Summit

  6. 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 Self-Managing Networks Summit

  7. 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 Self-Managing Networks Summit

  8. 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 Self-Managing Networks Summit
