Active Measurement Tool (AMT)
Linege Game Traffic Analysis
System Architecture
Main Features of AMT
Previous Analysis Result
1. Active Measurement methodology - use probe
packet - cf) Passive Measurement methodology 2.
supports both IPv4 and IPv6 3. Time
Synchronization - use NTP (network time
protocol) - use GPS or CDMA module as NTP
source 4. Time Stamping - at Data link layer gt
remove cross layer delay 5. Result Data
Gathering - gather result data just after
measurement is ended - according to OWAMP
document 6. Result Metric - one-way delay -
packet loss rate - delay jitter
