Problems solved by technology

[0004] However, in the above method, when the switching equipment in the network needs to have a self-detection function or a device supporting SND technology, the switching equipment can detect whether the switching equipment is congested and send a congestion warning message. Therefore, the processing of network congestion depends on Switching equipment in the network, so, when the above method is used to deal with network congestion, the requirements for switching equipment in the network are relatively high

Embodiment Construction

[0048] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0049] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific sequence of objects. For example, the first controller, the second controller, etc. are used to distinguish different controllers, not to describe a specific order of the controllers.

[0050] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more ...

Abstract

Embodiments of the present invention provide a method, device and system for dealing with network congestion, which relate to the field of communication technology and can determine a congested link in the network without relying on switching equipment in the network. The method includes: the first controller obtains at least two pieces of data flow information, and the first controller determines that the first link is a congested link according to the at least two pieces of data flow information, and the at least two pieces of data flow information include at least two Paths of one data flow and states of at least two data flows, wherein the path of one data flow includes at least one link, and the state of one data flow includes a congested state or a non-congested state.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for dealing with network congestion. Background technique [0002] With the continuous development of network technology, the network is more and more widely used, and user equipment (user equipment, UE) transmits data more and more frequently through the network. During the process of data transmission, when congestion occurs in the network, the transmission performance of the network may be degraded, affecting data transmission. [0003] Currently, in the process of dealing with network congestion, a switching device (such as a switch or a router) in the network that has a self-detection function or supports a software defined network (software defined network, SDN) technology can detect a location where congestion occurs in the network. Specifically, when each switching device in the network detects that a ce...
