ILT-U-3976
Ethernet Forwarding Behavior Benchmarking. RFC2889-aligned proficiency testing for Ethernet forwarding behavior evaluation
DETERMINATION | METHOD |
| Forwarding Rate Determination | Determination of the maximum forwarding rate under stable Ethernet forwarding conditions in accordance with RFC 2889 — Forwarding Rate methodology. Measurements shall be performed for all mandatory Ethernet frame sizes using controlled Layer-2 traffic conditions. |
| Address Learning Determination | Determination of the DUT MAC address learning behavior and forwarding consistency in accordance with RFC 2889 — Address Caching Capacity methodology. Includes verification of learned-address forwarding stability and identification of abnormal learning behavior. |
| Broadcast Forwarding Determination | Determination of DUT behavior during Ethernet broadcast traffic forwarding in accordance with RFC 2889 broadcast forwarding evaluation principles. Includes validation of forwarding propagation and forwarding consistency under broadcast traffic conditions. |
| Congestion Behavior Determination | Determination of DUT forwarding behavior under oversubscription and congestion conditions in accordance with RFC 2889 congestion-control and overload testing principles. Includes characterization of forwarding degradation and frame-loss behavior. |
| Forwarding Stability Verification | Verification that the DUT maintains stable Layer-2 forwarding operation during benchmark execution without interface instability, forwarding interruption, or abnormal forwarding behavior. Methodology aligned with RFC2889 operational execution principles and PT operational requirements. |
| Sequence Integrity Verification | Verification of frame-order continuity, duplicate frames, and missing frames using sequence-number verification techniques aligned with RFC2889 forwarding validation practices. |
| Reproducibility and Repeatability Assessment | Evaluation of internal measurement consistency and interlaboratory reproducibility based on repeated benchmark execution and statistical comparison of participant results. Methodology derived from RFC2889 benchmarking discipline and PT statistical evaluation procedures. |
