Data flux management method based on communication terminal

Abstract

The invention relates to a method used for managing and controlling data flows based on a communication terminal. The communication terminal with the management function (called management terminal for short) is gained according to prearranged rules; the communication terminal which has no management terminal address sends a request to the management terminal according to the address and waits for gaining priority threshold; if the waiting overtimes, the data to be sent is sequentially read and sent, otherwise the priority values of the data to be sent are sequentially read and compared to the priority threshold fed back by the management terminal; the data with the priority higher than the threshold is sent sequentially; for the data with the priority lower than the threshold, the priority thereof is weighted and improved, and the data is memorized at the tail of the data queue to be sent and waits to be sent in the next period. The method prevents the communication terminal from forming jamming when sending data, avoids the possibility of overtime re-sending caused by that the low priority data is abandoned by network equipment when the network jams, and reduces the occupying on the network resource after the data is sent and before the data is abandoned.

Description

technical field [0001] The invention relates to a communication terminal-based data flow management method. Background technique [0002] At present, most of the existing communication terminals are not intelligent, and can only complete communication tasks, and the tasks of communication control, such as data flow and priority management, are handed over to business applications or management devices in the network. Business applications can require data to be marked according to the 802.1p specification to achieve QoS (QoS is a security mechanism of the network, a technology used to solve problems such as network delay and congestion), but this management mode is to discard network management It is implemented with low-priority data in the device, so it has a certain lag. The data sender cannot receive the response from the receiver and delays retransmission, which seriously affects the timeliness of communication. At the same time, after the data is sent, it also needs t...

Problems solved by technology

Business applications can require data to be marked according to the 802.1p specification to achieve QoS (QoS is a security mechanism of the network, a technology used to solve problems such as network delay and congestion), but this management mode is to discard network management It is implemented by low-priority data in the device, so it has a certain lag. The data sender cannot receive the response from the receiver and delays retransmission, which seriously affects the timeliness of communication.

At the same time, after the data is sent, before it reaches the network device via the line and is discarded, it also needs to occupy network resources and affect the communication of other terminals.
