Embodiment Construction

[0061] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0062] like figure 1 As shown, the network fault detection method in Embodiment 1 of the present invention is executed by the server, including:

[0063] Step 11. Receive a network fault detection instruction from the client, where the network fault detection instruction includes the identifier of the tunnel to be detected.

[0064] In the embodiment of the present invention, according to the characteristics of end-to-end communication in the PTN network architecture, the communication link between the network element nodes at both ends is called a tunnel. Here, the tunnels that need to be detected for failure are referred to as tunnels to be detected. Packet transmission in the tunnel...

Abstract

The invention provides a network fault detection method and a network fault detection device, and relates to the communication technology field. Business operation in a network is guaranteed. The network fault detection method comprises steps that a network fault detection instruction of a client is received, and comprises an identification of a to-be-detected tunnel; network elements included by the to-be-detected tunnel are determined according to the identification of the to-be-detected tunnel; message counting instructions are transmitted to the network elements, and the network elements are used to count a number of messages received and/or transmitted by the network elements according to the message counting instructions; message counting results transmitted by the network elements are received, and whether the faults of the network elements occur is determined according to the message counting results, and the message counting results comprise the number of the messages received and/or transmitted by the network elements. The network fault detection method and the network fault detection device are mainly used for a PTN technology.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a network fault detection method and device. Background technique [0002] PTN (Packet Transport Network, Packet Transport Network) is a packet-based routing architecture, which can provide technical support for multiple services. In a PTN network, if packet loss occurs in an end-to-end tunnel, services carried on the tunnel will be affected. In the existing solution, it is possible to determine whether packet loss occurs in the tunnel through the packet sending and receiving conditions of the tunnel head node. However, the existing solution cannot locate the failed network element, so as to accurately solve the network failure, which affects the operation of services in the network. Contents of the invention [0003] In view of this, the present invention provides a network fault detection method and device to ensure the operation of services in the network. ...
