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

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

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 Landmarks Target Enter target Pings min/avg/max from landmarks to targets 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):
