Flow control method and monitoring terminal

A flow control and monitoring-end technology, applied in the field of communication, can solve the problem that the effect of the number of data retransmissions is weakened, the output buffer is full and the data is discarded or not is not in a one-to-one correspondence, 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] like 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 termi...

Abstract

The invention discloses a flow control method and a monitoring terminal. The method comprises: the monitoring terminal performs real-time prediction on the first data packet pre-sent by the data input terminal; when the first data packet is predicted to be at risk of being discarded , sending a pause message to the data input end; and controlling the data input end to send the first data packet according to the pause message. The present invention controls the sending of data packets by the data input end by monitoring and pre-judging the data packets sent by the data input end, thereby reducing or even eliminating the probability of data packet discarding and achieving the reduction of data packet duplication under the premise of fully utilizing the bandwidth. The purpose of sending times is very flexible and precise.

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 ...
