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

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

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
Landmarks
Target
Enter 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
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
13
Topology Service for PerfSONAR

• PerfSONAR
• Measurement Point Service
• Measurement Archive Service
• Authentication Service
• Lookup Service
• Topology Service
• Transformation Service

14
Proposals (under process)

• To establish a perfSONAR based network monitoring
  infrastructure in Pakistan
• Next Generation Network Monitoring for Pakistan
• To join the International perfSONAR project
  (currently Europe, US Brazilian NRENs)
