Executive Summary

Ethernet is the indisputable de-facto technology for local area networks due to its simplicity, low cost, and wide scale adoption. In recent times, Ethernet has entered new networking areas such as Metro Area Network (MAN) and Industrial Area Network (IAN) where specialized protocols dominate the market. In addition to the well known advantages, Ethernet acts as the common platform to integrate multiple protocols. However, Ethernet falls short of the stringent resilience requirements mandated by applications in MAN and IAN, despite progress made by the community on additional standardization.
