Motivation

Motivation

  • Measurement is necessary to determine the health and capabilities of the network connection as well as to locate performance problems when they occur. [1]

  • Computer system administrator or network operator has some measurement capability within their own domain. [1]


Objective

Objective

  • to provide a basis for the understanding and analysis of active measurement data so that one can use this data to better understand their network


Etop system

eTOP System

  • Measurement method

  • System Architecture

  • Topology

  • Data Presentations

  • System environment

    • Database server

    • Measurement Machine


1 measurement method

1. Measurement Method

Continue.. eTOP System

  • Active measurement

  • Metrics and tools

    • ICMP: ping

      • Round Trip Time (ms)

      • Packet Loss (%)

    • TCP Throughput: iperf [1]

      • Bandwidth (kbps)

    • UDP Throughput: iperf

      • Bandwidth (kbps)

      • Packet loss (%)

      • Jitter


1 measurement method1

1. Measurement Method

Continue.. eTOP System

  • Send ICMP packet using ping check whether machine is down or not parse RTT/ packet loss

  • Send probe packet using iperf parse TCP Throughput metrics parse UDP Throughput metrics

  • Insert parsed measurement data into central database system


2 system architecture

2. System Architecture

Continue.. eTOP System

  • Components

    • Active Measurement Point (AMP)

    • Trusted Central Database (DB)

    • Data Collection Component (DCC)

    • Data Presentation Component (DPC)
