The document proposes eliminating the data link layer and moving error handling to the network layer when transmitting data over fiber using IPv6. This would simplify the OSI model, improve performance by reducing overhead, and increase transmission speeds by removing the data link header and placing error checking in the IPv6 extension header rather than at the data link layer. It also discusses the need for dual stacking to process both existing and new transmission architectures during a transition to this approach.
