This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. The (TCP) and the (UDP) only need one for , bidirectional traffic.
UDP is a connectionless protocol meaning that messages are sent without negotiating a connection and that UDP doesn't keep track of what it has sent. [ 1 ] [ 2 ] UDP provides checksums for data integrity , and port numbers for addressing different functions at the source and destination of the datagram.
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet ...
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.
Proto – The name of the protocol (TCP, UDP, etc.). On some systems, the protocol name may be followed by "4" or "6", depending on whether the protocol is running over IPv4 or IPv6. Local Address – The IP address of the local computer and the port number being used.
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.
For such applications, protocols like the Real-time Transport Protocol (RTP) operating over the User Datagram Protocol (UDP) are usually recommended instead. [13] TCP is a reliable byte stream delivery service that guarantees that all bytes received will be identical and in the same order as those sent.
