Datagram distribution service (NetBIOS-DGM) for connectionless communication. Session service (NetBIOS-SSN) for connection-oriented communication. (Note: SMB, an upper layer, is a service that runs on top of the Session Service and the Datagram service, and is not to be confused as a necessary and integral part of NetBIOS itself. It can now run ...
The Name Service, according to RFCs 1001 and 1002, is called NetBIOS Naming Service or NBNS. Microsoft WINS is an implementation of NBNS. It is worth saying that due to constant development of the way in which the Name Service handles conflict or merges, "group names" varies from vendor to vendor and can even be different by version e.g. with ...
Microsoft EPMAP (End Point Mapper), also known as DCE/RPC Locator service, [71] used to remotely manage services including DHCP server, DNS server and WINS. Also used by DCOM: 137: Yes: NetBIOS Name Service, used for name registration and resolution [72] [73] 138: Assigned: Yes: NetBIOS Datagram Service [11] [72] [73] 139: Yes: Assigned ...
SMB originally operated on NetBIOS over IEEE 802.2 - NetBIOS Frames or NBF - and over IPX/SPX, and later on NetBIOS over TCP/IP (NetBT), but Microsoft has since deprecated these protocols. On NetBT, the server component uses three TCP or UDP ports: 137 (NETBIOS Name Service), 138 (NETBIOS Datagram Service), and 139 (NETBIOS Session Service).
NetBIOS Frames (NBF) is a non-routable network-and transport-level data protocol most commonly used as one of the layers of Microsoft Windows networking in the 1990s. NBF or NetBIOS over IEEE 802.2 LLC is used by a number of network operating systems released in the 1990s, such as LAN Manager, LAN Server, Windows for Workgroups, Windows 95 and Windows NT.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.

The number of sessions in the server side is limited only by memory and can grow as new connections arrive, but the client must allocate an ephemeral port before sending the first SYN to the server. This port remains allocated during the whole conversation and effectively limits the number of outgoing connections from each of the client's IP ...
