Problems solved by technology

The switch can forward the data accordingly, but during the forwarding process, the actual transmission of the data cannot be known
In the existing technology, it is impossible to determine whether the forwarding path is faulty. Even if some detection devices can detect path faults, the detection workload is heavy and the detection time is too long

Embodiment Construction

[0048] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0049] Such as Figure 1-Figure 2 As shown, the embodiment of the first aspect of the present invention proposes a controller for determining path faults, including:

[0050] A first determining module, configured to determine a head-end switch, a tail-end switch, and a path to be detected between the head-end switch and the tail-end switch;

[0051] The second determination module is configured to determine a key switch on the path to be detected; the key switch includes at least two branch paths; the branch path is a path from the head end switch to the key switch;

[0052] An establishment module, configured to establish a transmission channel between the head-e...

Abstract

The invention discloses a controller and system for determining path faults, comprising: a first determination module; a second determination module; an establishment module; and a control module, which is used to control a head-end switch to send a detection message to a key switch through a transmission channel; Receiving the first feedback messages returned based on the branch paths included in the key switch; when determining that the number of the first feedback messages is equal to the preset number, generating a confirmation result and controlling the head-end switch to send to the key switch; controlling the key switch sending the detection message to the next switch of the key switch; if the second feedback message sent by the next switch is received within the preset time period, it means that the path between the key switch and the next switch is normal, Otherwise, it indicates that the path between the critical switch and the next switch is faulty. It can accurately detect whether the forwarding path is faulty, reduce the detection workload, and shorten the detection time.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a controller and a system for determining path faults. Background technique [0002] With the continuous development of communication technology, OpenFlow protocol applications are born, including controllers and switches. The switch can forward the data accordingly, but during the forwarding process, the actual transmission status of the data cannot be known. In the prior art, it is impossible to determine whether the forwarding path is faulty. Even if some detection devices can detect path faults, the detection workload is heavy and the detection time is too long. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, the first object of the present invention is to provide a controller for determining path failure, which can accurately detect whe...
