  1. CPR and GAMMONDeployment Experiences. Warren Matthews Georgia Institute of Technology.

  2. Campus Backbone group maintain 180 buildings, 1700 switches, 55000 ports. Southern Crossroads gigapop (SOX) Provides connectivity for 20+ Universities throughout the South East 10Gbps link to Abilene backbone. Georgia Tech Office of Information Technology http://www.oit.gatech.edu

  3. Measurement Infrastructure typically means WAN monitoring But problems are LAN and host based Network Operations Single point of view Catastrophic failure is easier to detect Little quantitative data to troubleshoot performance problems Motivation Office of Information Technology http://www.oit.gatech.edu

  4. Campus-wide Network Performance Monitoring and Recovery 50+ hosts on Campus Collocated with switches in data closets Multiple views of the network Especially the users view Regular tests across campus network CPR Office of Information Technology http://www.oit.gatech.edu

  6. Georgia Measurement and Monitoring State-wide initiative Distance Learning and Professional Education (DLPE) Valdosta State University, Armstrong Atlantic State University, Barrow County School System. GAMMON Office of Information Technology http://www.oit.gatech.edu

  7. Local ISPs Major providers (Level3, Qwest, Charter) Residential (SpeedFactory, BellSouth, Charter, Cox) Global collaborations International focus in strategic plan Metz, Shanghai Leverage Global PMP Infrastructure and communicate using emerging standards Other Deployments Office of Information Technology http://www.oit.gatech.edu

  8. On the whole, very smooth Control of Network Firewall Physical access Control of satellite server, DNS Warmly welcomed Help is on the way Pass the buck Deployment Experience Office of Information Technology http://www.oit.gatech.edu

  9. Donated hardware Cheap Flakey Scavenging of parts before donation GAMMON/International deployment faces more of the traditional challenges Deployment Experience Office of Information Technology http://www.oit.gatech.edu

  10. No in-house development of measurement tools. Original plan also didn’t include much visualization. Inconvenient to click through numerous graphs Toolset Office of Information Technology http://www.oit.gatech.edu

  11. Currently Smokeping - roundtrip time and graphs. Nagios - Services. Security - nessus and nmap. Also available Iperf (bwctl) - TCP throughput only. Pathchar, traceroute Coming soon NDT (central, distributed) Test bed for tools under development Measurements Office of Information Technology http://www.oit.gatech.edu

  12. Passive Monitoring of border traffic Bwctl.sox is outside GT. OWAMP NTP Alleged network problems are often issues with applications Added application monitoring using Nagios Information Security CPR as a platform for other groups, research Measurement Experiences Office of Information Technology http://www.oit.gatech.edu

  13. Analysis Create base-lines for historical comparison Use multiple view to detect location Middleware Alarm system Plateau detector (AMP), RIPE-TT How should we react to alarms? Troubleshooting guide Analysis Office of Information Technology http://www.oit.gatech.edu

  14. Initial design was active monitoring Integrate with passive tools Wireless tools, NETI Provide a platform for localized netflow reports Initial design was to avoid looking at graphs Auto detect and alarms MyCPR Analysis Experience Office of Information Technology http://www.oit.gatech.edu

  15. Configurable alarms and graphs MyCPR Office of Information Technology http://www.oit.gatech.edu

  16. CPR has helped solve numerous issues Firewall Network slowness for file sharing Dropped sessions Not everything is a network issue Case Studies Office of Information Technology http://www.oit.gatech.edu

  17. Don’t assume anything If you don’t measure, you don’t know. Don’t expect people to do what they should When one door closes, another one opens. Experiences Office of Information Technology http://www.oit.gatech.edu
