    Connection-Oriented ServicesA connection is a set of operations performed by two peers before they communicate. This includes applying for memory resources, initializing several variables, and negotiating communication parameters. Connection-oriented services are similar to people calling, first through the call operation to get a circuit that can talk, then talk, and then hang up after the call is completed, freeing up the occupied circuit.

    Connection-oriented services also go through three stages: before data is transmitted, a connection is established, data is transmitted after the connection is established, and the connection is released after the data is transmitted. Connection-oriented services that ensure the order in which data is transmitted and the reliability of transmission.

    Connectionless servicesConnectionless services are similar to the exchange of letters in everyday life. It only has this stage of data transfer. In the course of correspondence, only the writer is required to work, and the recipient is not required to be at work.

    Similarly, in a connectionless service, communication can occur as long as the sending entity is active. Connectionless service eliminates other overhead except data communication because there is no connection establishment and release process, so it has the advantage of being flexible, convenient, and fast, and is especially suitable for transmitting a small number of sporadic packets, but the connectionless service cannot prevent the loss, duplication or disorder of packets.

    To put it simply, connection-oriented: the information is uploaded from a line that has already been built, and there will be no change in the middle Connection-oriented: the transmission line of the information is temporarily established before the transmission is initiated, and the line will not be available after the transmission.

    Connection-oriented, a network protocol that relies on display communication and blocking between the sender and receiver to manage data transmission between both parties. A feature of a network system that requires a connection to be established before data can be sent between two computers.

    Connectionless is one of the communication technologies, which means that the two parties do not need to establish a communication line in advance, but send each packet (packet) with a destination address to the line, and the system independently selects a route for transmission. The postal system is a non-connected model, with a network of selected routes and a form of dissemination by goddesses; IP and UDP protocols are a kind of connectionless protocol.

    Connection-oriented communication has data order-preserving, while connection-oriented communication cannot ensure that the order of receiving data is consistent with the order of sending data. There are three phases of connection-oriented, the first is to establish a connection, in which a request is made to establish a connection. Data transfer can only start after the connection has been successfully established, which is the second stage.

    Then, when the data transfer is complete, the connection must be released. And for the connection-less there are not so many stages, it directly carries out the data transfer.

    In the connection-oriented approach, a data communication channel (circuit) is established between two endpoints. This channel provides a predefined path for sequentially sending packets of packets over the network, similar to voice**. The sender maintains contact with the receiver to coordinate the signals received or failed by the session and packet packets.
