Problems solved by technology

[0004] In the above process, the branch routers use the same sending frequency to send probe request packets to the central router, but it is difficult for the branch routers to accurately determine the sending frequency of the probe request packets
If the sending frequency of the detection request message is too high (for example, on the order of seconds), the burden on the main 3G link and the

Embodiment Construction

[0043] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a method for detecting network quality, which is applied to a network including a first router and a second router. The first router may be a router in a branch office of an enterprise. The first router may be called a branch router, the second router may be a router in the central organization of the enterprise, and the second router may be called a central router. by figure 1It is a schematic diagram of the application scene of the embodiment of the present invention, the first router and the second router are connected through a 3G network, the first router includes a main 3G interface and a backup 3G interface, and the first router accesses the link of the 3G network through the main 3G interface. The road is the main 3G link, the link that the first router accesses the 3G network through the backup 3G interface is the backup 3G link, and the second router and the 3G n...

Abstract

The invention discloses a method and device for detecting the network quality. The method includes the steps that an RSSI value of a main 3G link is determined through a first router; when the RSSI value is larger than an alarm threshold, the network quality of the main 3G link is determined to be link normality; when the RSSI value is smaller than or equal to the alarm threshold and larger than an error threshold, the network quality of the main 3G link is determined to be link alarming; when the network quality is link normality, a backup 3G interface is closed, and detecting messages are sent to a second router with the first sending frequency through the main 3G link; when the network quality is link alarming, the backup 3G interface is opened, and the detecting messages are sent to the second router with the second sending frequency through the main 3G link, wherein the first sending frequency is smaller than the second sending frequency. By means of the method and device, when link normality exists, the number of the sent detecting messages can be decreased; when link alarming exists, faults of the main 3G link can be detected in time, and then a backup 3G link can be rapidly started in a switched mode.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network quality detection method and equipment. Background technique [0002] 3G (Third Generation Mobile Communication System) has high access bandwidth and can provide good quality of service. As the 3G network matures, more and more enterprise branches use 3G links instead of wired links to access the enterprise center. Such as figure 1 As shown, in order to improve the stability of branch office access, the branch router is configured with a main 3G interface and a backup 3G interface. The link that the branch router accesses to the 3G network through the main 3G interface is the main The link entering the 3G network is a backup 3G link; in addition, the central router and the 3G network can be connected in a wired manner. When the main 3G link does not fail, the branch router uses the main 3G link to communicate with the central router; when the main 3G link fails...
