NetBIOS Frames (NBF) Protocol Transport

The NetBIOS Frames (NBF) protocol is a non-routable transport that provides NetBIOS services over IEEE 802.2 as specified in [NETBEUI]. The NBF NetBIOS session service makes use of IEEE 802.2 Logical Link Control connection-oriented services (Type 2), as specified in [IEEE802.2-1998].

IBM Corporation first introduced the NBF protocol specification in 1985 (see [NETBEUI]). The NBF transport protocol is sometimes referred to as NetBEUI (NetBIOS Extended User Interface) in Microsoft documentation (for more information, see [NBF]).
