Title: MAGGIE NIIT SLAC On Going Projects


1
MAGGIE NIIT- SLACOn Going Projects
  • Measurement Analysis of Global Grid Internet
  • End to end performance

Projects
  • PingER
  • DataGrid WAN Monitoring Infrastructure (DWMI)
    Terapaths Monitoring Project
  • Trilateration Utility for Locating IP Addresses
  • Event Detection
  • Event Diagnosis
  • Topology Service for PerfSONAR

4
PingER Methodology
gtping remhost
Uses ubiquitous ping
Remote Host (typically a server)
Internet
Monitoring host
10 ping request packets each 30 mins
Once a Day
Ping response packets
Data Repository _at_ 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
  • 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

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 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)
