In 1985, IBM went forward with the token ring network scheme and a NetBIOS emulator was produced to allow PC-Network applications to work over this new design, using the NBF protocol to provide the NetBIOS services over the IEEE 802.2 Logical Link Control layer.
In 1985, IBM went forward with the token ring network scheme and a NetBIOS emulator was produced to allow NetBIOS-aware applications from the PC-Network era to work over this new design. A new networking protocol, NBF, was simultaneously produced to allow NetBEUI (NetBIOS) to provide its services over token ring--specifically, at the IEEE 802.2 Logical Link Control layer.
