network channels. Reliable transfer of data: Data in the trans-network transmission process may be errors, loss, chaos and other problems, Transport layer protocol must be able to detect and correct these problems. Flow control: When the sending rate of the sender exceeds the receiver's receiving rate, or when the resource is insufficient to support the processing of the data, the transport layer is responsible for controlling the traffic at a reasonable level, whereas the transport lay
