Part 1

Theory of Ethernet technology and testing

  • History
  • Datacom technology overview
    • Ethernet (10Base-T, CSMA/CD, half-duplex, full-duplex)
    • Fast Ethernet (100Base-T, auto-negotiation)
    • Gigabit Ethernet (1000Base-T)
  • EtherSAM
  • Predefined Ethernet frame sizes (RFC 2544)
  • Throughput, burstability, frame loss and latency (RFC 2544)
  • RFC 3393 (jitter)
  • RFC 791 (internet protocol v.4) and RFC 2475 (service differentiation)
  • Error performance-monitoring system (EPMS − G.821 and G.826)
  • Virtual local-area networks (VLANs)
  • IEEE 802.1 Q/p and IEEE 802.1 Q-in-Q
  • Service-disruption measurements
  • Bit error rate (BER) testing
  • Multistream generation application
  • 10 Gigabit Ethernet protocol
  • LAN and WAN PHY
Part 2

Ethernet testing applications

  • Ethernet networks − what to test and how to test them
  • Performance analysis (RFC 2544)
  • BER testing (layer 1 and layer 2)
  • Dual test sets/Smart loopback
  • Frame analysis
  • TCP throughput
  • Expert mode
  • Scripting


Basic comprehension of math and physics

The first part of this course consists of lectures using PowerPoint presentations and demonstrations, while the second part consists of specific hands-on testing exercises.


Attendees will receive a binder containing copies of presentations and other printed handouts, if applicable. When available, a CD containing the electronic version (PDF format) of the presentation, as well as related application notes, will also be provided.
