“Real Life” Verification

Only simulation not enough

Necessary to verify simulation results in the real world using:

Test-Beds

Real Networks

Demonstration Environment

Network independent

consider the network to analyze as a “cloud”

single hop or multiple hop analyzes (entire network)

TCP Analyzer

collection of several tools and programs to evaluate TCP

Tools: DBS -> predefined complex traffic patterns (tcp, upd) FTP: regular ftp-transfer

netperf: single connection, bandwidth & latency

see also RFC 2398

User Application Platform

computer running any “daily life” application

subjective test of network’s QoS
