BiographyHans R. Mueller and Werner Bux's research formed the foundation for the revolutionary token ring technology. A key local area networking standard from the 1980s through the 1990s, token ring introduced several benefits, including automatic fault detection and recovery, reduced delays at ring interfaces and stable transmission. The legacy of the technology can be seen in today's high-speed, fault-resistant fiber optic LANs and Ethernet. Mr. Mueller and Dr. Bux's innovative system to automatically detect and recover from faults on the network has since become a part of many other networking systems and of IEEE Standard 802.5.
Dr. Bux made major contributions to token ring's architecture, demonstrated the superior performance of the token ring and contributed to the development of international communications standards. A Fellow of the IEEE, he has served the IEEE in various roles including as senior editor of the IEEE Journal on Selected Areas in Communications and on the IEEE 802.2 and 802.5 Standards Working Groups. He is editor-in-chief of the Performance Evaluation journal. His honors include two IBM Outstanding Innovation awards and a corporate award. Dr. Bux is manager of IBM Zurich's Communication Systems department.
