First, define a concept: Each TCP socket has a sending buffer and a receiving buffer in the kernel, the full duplex mode of TCP and the Sliding Window of TCP depend on the two independent buffers and the filling status of the buffer. The receiving
The first is to define a concept: Each TCP socket has a send buffer and a receive buffer in the kernel, TCP's Full-duplex mode of operation and the TCP sliding window depend on the two separate buffers and the padding state of the buffer. The
