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

LandmarksTargetEnter target

Pings min/avg/max from landmarks to targets

Traceroutes from landmarks to targets

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
