  3. Projects • PingER • DataGrid WAN Monitoring Infrastructure (DWMI) Terapaths Monitoring Project • Trilateration Utility for Locating IP Addresses • Event Detection • Event Diagnosis • Topology Service for PerfSONAR • Network Weather Forecasting • Proposals under discussion

  4. PingER Methodology >pingremhost Uses ubiquitous ping Remote Host (typically a server) Monitoring host Internet 10 ping request packets each 30 mins Once a Day Ping response packets Data Repository @ SLAC Measure Round Trip Time & Loss

  5. PingER (Sub Projects) Most of South Asia has good connectivity • SmokePing PingER Integration • ViPER - Visualization for PingER • AMP PingER Integration • PingER Executive Plots • PingER Management • ICFA/SCIC Report • Greater Coverage Area • Min RTTs are decreasing globally For S.Asia Loss decreasing, still far behind others

  6. DataGrid WAN Monitoring Infrastructure (DWMI) Terapaths Monitoring Project • Terapath • fully configurable passive monitoring infrastructure based on netflow records exported from routers • data collection and aggregation schemes • Flexible reporting infrastructure Traffic In Traffic out

  7. Topology Service for PerfSONAR • PerfSONAR • Measurement Point Service • Measurement Archive Service • Authentication Service • Lookup Service • Topology Service • Transformation Service

  8. Topology Service for PerfSONAR • To archive network topology information needed for the operation of perfSONAR and • Visualization tools. • Each AS has to maintain its own topology database and publish it to the perfSONAR framework. • The ToS will define a topology information data format to allow for an easy processing of topology information. • Beside of the current topology, it should contain past and planned network configuration. • Each AS should register its ToS with the Lookup Service, so that the topology becomes available to every interested user.

  9. Trilateration Utility for Locating IP Addresses (TULIP) • www.slac.stanford.edu/comp/net/wan-mon/tulip/ • Java applet (needs Java Webstart) • Friendly client, easy vizualization • Need landmarks around world Enter target Pings min/avg/max from landmarks to targets Landmarks Target Traceroutes from landmarks to targets

  10. Automated Event Detection Based on IEPM-BW Different Network Monitoring tools (Ping, IPerf, Thrulay, Pathchirp etc) Variety of Metrics (Throughput, RTT, available bandwidth, Traceroutes) Topology (5 Monitoring Hosts, Over 25 Monitored nodes) Different Mechanisms (Holt-winters, Plateau etc) Alerts are • Detected • Reported through e-mail • Stored in database • Made available on web

  11. Event Diagnosis • End-to-end analysis; assume that the problem may not just be from the network • Initiate analysis of all available results when an event is detected • Search Event DB for each metric checked on each host and used to cross correlate results between Monitoring Hosts or Monitored Nodes • Use heuristics defined with a simple summation algorithm to narrow down the location of a fault. • Tiered system used to pin-point exact cause of problem. • Start from high level to very low level to help locate, identify and verify cause of alert Heuristics based approach

  12. Proposals (under process) • To establish a network monitoring infrastructure in Pakistan • Next Generation Network Monitoring for Pakistan • to join the International perfSONAR project (currently: Europe, US & Brazilian NRENs):
