Method, device and core network entity for dealing with network congestion

Abstract

The disclosure discloses a method, an apparatus and a core network entity for processing network congestion, which enable: extracting adjacent data packets which have the same number as that of the preset interval value from an output port queue when the output port is detected to be in congestion state, and acquiring the source terminal address information of the adjacent data packets; searching for the source terminal transmitting the most data packets according to the source terminal address information; and transmitting a congestion information to the source terminal transmitting the most data packets. By extracting adjacent data packets which have the same number as that of the preset interval value from an output port queue when the output port is detected to be in congestion state, and acquiring the source terminal address information of the adjacent data packets; searching for the source terminal transmitting the most data packets according to the source terminal address information; and transmitting the congestion information to the source terminal, the disclosure makes the source terminal decrease the data transmission rate, so as to eliminate the network congestion. Therefore, the success rate of eliminating the network congestion is increased.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and core network entity for dealing with network congestion. Background technique [0002] With the rapid development of Internet technology, the volume of interactive services on the network is increasing, and users have higher and higher requirements for network performance. At the same time, in the process of business data interaction, problems such as network congestion, delay, and packet loss are becoming more and more serious. [0003] In the prior art, the congestion state of the network is generally eliminated in the following ways: the core network entity configured with a congestion detection function detects its own outgoing port, and samples the outgoing port queue; if the port is detected to be in a congested state, a congestion state is created. message; send the congestion message to the terminal corresponding to the sampling point c...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned ways to eliminate network congestion often make judgment errors, see figure 2 , multiple data packets are sequentially buffered in the B3 outbound queue, and the data packets contain the source address information of the sent data packets, from figure 2 It can be seen that the congestion of B3 is caused by terminal 1. However, when B3 detects that the outbound port is in a congested state, the source terminal corresponding to the sampled data packets drawn from the outbound port queue is terminal 2. At this time, B3 determines that it is terminal 2. Cause the outbound port to be congested, and then send a congestion message to terminal 2 to make terminal 2 reduce the data transmission rate

Terminal 1, which actually causes B3 congestion, still continues to transmit high-speed data

In this case, the congestion state of B3 not only cannot be relieved, but may also cause the deterioration of the congestion state
