This thesis work is aimed at testing and verifying 100 GbE (100 Gigabit Ethernet) networking equipment and 100 GbE networks, and performance benchmarking 100 GbE on both high-end networking hardware and common PCs. Verification of interoperability of 100 GbE equipment is especially important, since there are many implementations of 100 GbE networking interfaces, especially concerning optical interface modules. Performance testing was performed with both a precise instrument and regular software, on both high-end networking hardware (Cisco ASR9000 routers and Juniper QFX5110 switches) and regular PC hardware.

Measurement results suggest that current-generation, high-end networking equipment is already capable of handling 100 GbE at near line-rate speeds; but the measurements (and sometimes lack of them them) performed in this thesis work also reveal a concerning amount of interoperability issues between equipments confirming to one of the many 100 GbE standards, even as the same standard is implemented by different vendors; as well as surprisingly high potential in regular PC hardware for 100 GbE usage, suggesting that they will be capable of processing 100 GbE in 3 or 4 years.
