10 ping request packets each 30 mins
Once a Day
Ping response packets
Data SLAC
Measure Round Trip Time & Loss

5. PingER (Sub Projects) SmokePing PingER Integration
ViPER - Visualization for PingER
AMP PingER Integration
PingER Executive Plots
PingER Management
ICFA/SCIC Report
Most of South Asia has good connectivity
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
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
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)
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
Stored in database
Made available on web

11. Event Diagnosis Heuristics based approach
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):
