Embodiment Construction

[0035] The core idea of ​​the method for improving data transmission performance when the network is congested in the present invention is that when the link layer fails to send a data packet due to network congestion, the data packet is sent according to certain rules, such as IP quintuple information or QoS (Quality of Service) value, etc., enter the corresponding queue, wherein the five-tuple information of IP includes: source and destination address, source and destination port number, protocol number, and the corresponding queue includes: high priority queue, fragmentation temporary queue and lower priority queue. The real-time business enters the high-priority queue, and the large data packets to be sent are fragmented and put into the fragmented temporary queue, and other business data are put into the lower-priority queue. The real-time data packets are cross-scheduled into the fragments of the large data packets, so as to ensure that the data with high priority in the...

Abstract

The invention refers to a method for upgrading the transmission performance when the network is jammed. The method divides the big data package into pieces when the low rate loop is jammed, it reduces the length of data package, and turns into piece temporary queue, the data with high transmission priority are turned into the queue with high priority, makes the real-time service data with high priority are transmitted in the branch pieces crossly, avoids the delay and jitter when waiting the big data package, guarantees the service quality pointing to real-time service data, and it reduces the chaos order of branch piece messages extremely, at the same time, it can guarantee the data with high priority such as real-time service data can be dispatched in prior.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for improving data transmission performance when the network is congested. Background technique [0002] With the development of network communication technology, the requirements for data transmission performance in network communication are also increasing. In order to ensure the performance of data transmission in network communication, that is, ensure the reliable transmission of data to meet the communication needs of users, congestion management technologies such as PQ (Priority Queue) are usually used to manage the data transmission process. When the output interface is congested, The data flow can be classified according to the importance of the transmitted data, the level of service quality to be provided, etc., usually according to the business attributes carried by the data message to determine the priority of sending the data; and then send the ...
