  2. Server Message Block - Wikipedia

    en.wikipedia.org/wiki/Server_Message_Block

    SMB serves as the basis for Microsoft's Distributed File System implementation. SMB relies on the TCP and IP protocols for transport. This combination allows file sharing over complex, interconnected networks, including the public Internet. The SMB server component uses TCP port 445.

  3. Simple Network Management Protocol - Wikipedia

    en.wikipedia.org/wiki/Simple_Network_Management...

    All SNMP messages are transported via User Datagram Protocol (UDP). The SNMP agent receives requests on UDP port 161. The manager may send requests from any available source port to port 161 in the agent. The agent response is sent back to the source port on the manager. The manager receives notifications (Traps and InformRequests) on port 162 ...

    They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses, [ 1 ] However, many unofficial uses of both well-known and registered port numbers occur in ...

    They use one of two transport layer protocols: the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). In the tables below, the "Transport" column indicates which protocol(s) the transfer protocol uses at the transport layer. Some protocols designed to transmit data over UDP also use a TCP port for oversight.

  6. User Datagram Protocol - Wikipedia

    en.wikipedia.org/wiki/User_Datagram_Protocol

    A port is a software structure that is identified by the port number, a 16-bit integer value, allowing for port numbers between 0 and 65535. Port 0 is reserved but is a permissible source port value if the sending process does not expect messages in response. The Internet Assigned Numbers Authority (IANA) has divided port numbers into three ...

  7. Trivial File Transfer Protocol - Wikipedia

    en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol

    TFTP uses UDP as its transport protocol. A transfer request is always initiated targeting port 69, but the data transfer ports are chosen independently by the sender and receiver during the transfer initialization. The ports are chosen at random according to the parameters of the networking stack, typically from the range of ephemeral ports. [4]

  8. Packet switching - Wikipedia

    en.wikipedia.org/wiki/Packet_switching

    Examples of connectionless systems are Ethernet, IP, and the User Datagram Protocol (UDP). Connection-oriented systems include X.25, Frame Relay, Multiprotocol Label Switching (MPLS), and TCP. In connectionless mode each packet is labeled with a destination address, source address, and port numbers.

  9. Zero-configuration networking - Wikipedia

    It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Windows supports it in the form of Web Services for Devices and Devices Profile for Web Services. Many devices, such as HP and Brother ...
