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

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.
Trilateration Utility for Locating
IP Addresses (TULIP)

http://maggie.niit.edu.pk/newwebsite/tulip/



Java applet (needs Java Webstart)
Friendly client, easy vizualization
Need landmarks around world
Pings min/avg/max from landmarks to targets
Enter target
Traceroutes from landmarks to targets
Target
Landmarks
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
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
