The automatic repeat request (ARQ) protocol mainly included the stop-and-wait ARQ protocol and the continuous ARQ protocol. The continuous ARQ protocol also included the N-frame backward ARQ protocol and the selective repeat ARQ protocol. The work flow of the stop-and-wait ARQ protocol was as follows: the transmitting station must wait for an acknowledgment signal after sending out a frame, and then continue to send the next frame after receiving an acknowledgment signal, and then resend the frame after receiving a negative acknowledgment signal, and must resend the frame even if no acknowledgment signal is received within a certain time interval. The continuous ARQ protocol meant that the sender maintained a sending window of a certain size, and all the packets within the sending window could be sent out continuously without waiting for the other party's confirmation. Every time the sender received a confirmation, the sending window would slide forward by one packet. In the ARQ protocol that sent back N frames, after the sender sent a frame, it did not have to stop and wait for the other party's response. It could send several frames in a row. If it received a positive response from the receiver during the sending process, it could continue to send. If it received a negative response to a previous frame, all subsequent frames starting from that frame would be retransmitted. The selective repeat ARQ protocol can be used as a protocol for the transmission and acknowledgment of a message unit. When used as a protocol to transmit a message unit, the sending process continuously sends a number of frames according to a window of a specified size. Even if the frame is lost during the process, it will continue to send. The receiving process continued to receive and acknowledge frames even after the error. "Choose" was equally exciting.

Buddhism and Confucian novels

For example, Chuzhou Prefecture was built in the 27th year of the Yuan Dynasty (1290). The circumference of the city wall was about 5 kilometers. There was a certain layout in the city, including many streets. Zhongzhi Street was the main street.

From the end of the Qing Dynasty to the Republic of China, Lishui City was a place with developed commerce and prosperous streets. It was the political, economic and cultural center of ten counties including Jingning. At that time, the prosperity of commerce was due to the shipping of the Oujiang waterway.
