Embodiment 1

[0052] The embodiment of the present application operates in an SDN network scenario, and is an end-to-end fault location method in the SDN network scenario. It should be pointed out that the operating environment of the above information transmission method provided in the embodiment of the present application is not limited to the above network architecture.

[0053] In this embodiment, a method for locating a network fault running in the above network scenario is provided. figure 1 is a flow chart of a network fault location method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0054] Step S102, the control plane device sends a first diagnostic message to the designated node in the first forwarding node set on the service path, wherein the forwarding nodes in the first forwarding node set start with the designated node and proceed downwards in sequence A forwarding node forwards the first diagnos...

Embodiment 2

[0112] In this embodiment, a device for locating a network fault is also provided, which is applied to a control plane device. The device is used to implement the above embodiments and preferred implementation manners, and those that have already been explained will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0113] Figure 5 is a structural block diagram of a network fault location device according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:

[0114] The sending module 52 is configured to send a first diagnostic message to a designated node in the first forwarding node set on the service path, wherein the forwarding nodes in the...

Embodiment 3

[0127]The embodiment of the invention also provides a storage medium. Optionally, in this embodiment, the above-mentioned storage medium may be configured to store program codes for performing the following steps:

[0128] S1. The control plane device sends a first diagnostic message to a designated node in the first set of forwarding nodes on the service path, wherein the forwarding nodes in the first set of forwarding nodes use the designated node as the starting node and proceed to the next The forwarding node forwards the first diagnostic message;

[0129] S2. The control plane device receives the second diagnostic message fed back by the forwarding nodes in the first forwarding node set, and determines the forwarding node that feeds back the second diagnostic message to obtain a second forwarding node set, where the second The diagnostic message is a message obtained by duplicating the first diagnostic message by forwarding nodes in the first forwarding node set;

Abstract

The invention provides a network fault positioning method and device. The method includes the following steps: control plane equipment sends a first diagnostic message to a specified node in a first forwarding node set on a service path, and the control plane equipment receives a second diagnostic message fed back by a forwarding node in the first forwarding node set and determines the forwardingnode that feeds back the second diagnostic message to obtain a second forwarding node set, wherein the second diagnostic message is a message obtained by duplicating the first diagnostic message through the forwarding node in the first forwarding node set; and the control plane equipment determines the node with a network fault based on the second forwarding node set. By adopting the technical scheme, the problem that the positioning of the network fault in related technologies is high in difficulty and low in accuracy can be solved, and the process of conveniently and accurately finding out the node with the network fault can be implemented.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network fault location method and device. Background technique [0002] In the message exchange process in the related art, the message exchange network communication service based on the internet protocol is completed by the communication parties at both ends of the path and a series of network devices in the path in accordance with the rules. After a message is sent from the originating host, it will be sent to the first forwarding device on the path, which will process the message and send it to the second forwarding device on the path, and so on until it is sent to the receiving device. end host. Each forwarding device, its outgoing port, and the next forwarding device on the path it points to form a directional link. The complete path of network transmission is composed of such directional links in sequence, also known as a set of forwarding nodes. When any forwarding ...
