Flow control method and monitoring end

A flow control and monitoring technology, applied in the field of communication, can solve the problem that the output buffer is full and whether the data is discarded is not a one-to-one correspondence, and the effect of the number of data retransmissions is weakened, so as to reduce the number of retransmissions and eliminate data. The effect of the probability of packet dropping

Problems solved by technology

[0004] The existing technology is to adjust the data flow of the front-end sending end by monitoring the emptyness of the output buffer of the current stage. However, in devices with long data links between input and output, especially in devices with traffic supervision, the output buffer There is not a one-to-one relationship between the emptyness and fullness of the data and whether the data is discarded, so the effect of the existing technology to reduce the number of data retransmissions will be greatly weakened

Embodiment Construction

[0040] The solution of the embodiment of the present invention is mainly to control the sending of data packets by the data input end by monitoring and predicting the data packets sent by the data input end, thereby reducing or even eliminating the probability of data packet discarding.

[0041] Such as figure 1 As shown, a preferred embodiment of the present invention proposes a flow control method, including:

[0042] Step S101, the monitoring terminal performs real-time prediction on the first data packet pre-sent by the data input terminal;

[0043] Receive the second data packet currently sent by the data input end; the data transceiver device receives the second data packet currently sent by the data input end, that is, the previous stage sending device, and the second data packet is the data that has just arrived The data packet of the transceiver device; the data transceiver device sends the received second data packet to the monitoring terminal, and the monitoring te...

Abstract

The invention discloses a flow control method and a monitoring end. The method comprises the following steps: the monitoring end performs real-time pre-judgment on a first data packet pre-transmitted by a data input end; the monitoring end transmits a suspending message to the data input end when pre-judging that the first data packet carries the risk of being discarded; and the monitoring end controls the data input end to transmit the first data packet according to the suspending message. Data packet transmission by the data input end is controlled through monitoring and pre-judging of the data packet transmitted by the data input end, thereby reducing and even eliminating the probability of data packet discard, and achieving the purpose of reducing the number of times of data packet retransmission on the premise of fully utilizing the bandwidth. High flexibility and precision are achieved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a flow control method and a monitoring terminal. Background technique [0002] In the communication system, the total bandwidth of data transmission is limited, and a certain bandwidth needs to be agreed with each user in advance. When the user's data is greater than the agreed bandwidth, the redundant data needs to be discarded to prevent the user from crowding out other users. bandwidth, so that the legitimate traffic of other users is guaranteed. The discarded data needs to be resent by the user. If the traffic sent by the user is large and only a small part passes through the monitoring device, the number of times the data will be resent will greatly increase, which will waste a lot of resources. Therefore, it is very necessary to restrict user traffic at the entrance of the network to ensure the normal operation of the network. [0003] To solve this problem, it is ...
