The article argues that the token ring, while no longer existing, is not actually an example of technology that failed because the Ethernet technology has token ring features. The original IEEE 802.3 standard for the Ethernet is non-deterministic, which means that performance for any single station cannot be predicted. As networks got busier, the performance of the original Ethernet drastically declined. In contrast, the token ring was developed to be a deterministic network. It was only through the invention of the Ethernet switch in the mid-1990s that Ethernet technology avoided becoming obsolete because now it has become deterministic.
