Task for today
• Document the Ethernet configuration in
room 460
• IP adr., cabeling
• Measure the throuput
• Between to host with jperf
• Compare UDP and TCP with different packet
sizes
• Use wireshark to monitor the connection
Wiederholung
• Beschreiben Sie die statische Konfiguration einer IP
Adresse, DNS und dem Default GW!
• Beschreiben Sie die Konfiguration von Jperf für
unterschiedliche Messungen (UDP, TCP, kleine
Pakete, große Pakete, unterschiedliche Datenraten)!
• Welchen Datendurchsatz erhalten Sie? Begründen
und Diskutieren Sie den gemessenen Wert!
• Welche Filtereinstellung im Wireshark ist notwendig
um folgende Ergebnisse zu erhalten! (MAC Adr. des
Senders, IP Adr. des Empfängers, … )
