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

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

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

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) 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

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 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

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):
