Embodiment 1

[0065] The embodiment of the present invention provides a system for network fault handling, see figure 2 , the system includes a monitoring probe 41 and a network management device 42, the network management device 42 is connected to the monitoring probe 41 and the network element equipment in the packet transmission network, and the monitoring probe 41 includes a network element device deployed on each network element equipment in the packet transmission network Active probes and passive probes deployed on at least one network element device in the packet transport network, the active probes are used to send service flows to detect whether the packet transport network is faulty, and the passive probes are used to mirror and copy service flows to detect packet transport networks Whether it is faulty, the alarm information includes the identification of the monitoring probe and the type of fault;

[0066] The monitoring probe 41 is used to send alarm information to the networ...

Embodiment 2

[0087] The embodiment of the present invention provides another network fault handling system, which is applicable to the case where the active probe detects the failure of packet transport network service transmission in all the cases applicable to the first embodiment. In this embodiment, the packet transport network The network element devices include a first network element device and a second network element device, and the first network element device and the second network element device are different network element devices, see Figure 4 , the system implements the following steps to handle network failures:

[0088] Step 201: The active probe on the first network element device sends a service flow to the second network element device.

[0089] In practical applications, active probes can completely simulate common services of multiple protocol types in packet transport networks, such as HTTP services, File Transfer Protocol (English: File Transfer Protocol, referred...

Embodiment 3

[0114] The embodiment of the present invention provides yet another network fault handling system, which is applicable to the situation where the active probe monitors that the business fails to reach the key performance indicator (Key Performance Indicator, KPI for short) in all the cases where the first embodiment is applicable. In this embodiment, the network element devices in the packet transport network include a first network element device and a second network element device, and the first network element device and the second network element device are different network element devices, see Image 6 , the system implements the following steps to handle network failures:

[0115] Step 301: The active probe on the first network element device sends a service flow to the second network element device.

[0116] Specifically, the step 301 may be the same as the step 201 in the second embodiment, and will not be described in detail here.

[0117] Step 302: When the active ...

Abstract

The invention discloses a network fault processing system, and belongs to the technical field of networks. The system comprises a monitoring probe and network management equipment; the network management equipment is connected with the monitoring probe and network cell equipment in a packet transport network; the monitoring probe comprises an active probe and a passive probe; the active probe is used for sending a business flow to detect whether the packet transport network is faulted, and the passive probe is used for mirroring the business flow to detect whether the packet transport network is faulted; when the packet transport network is faulted, the monitoring probe sends alarm information to the network management equipment, wherein the alarm information comprises an identifier of the monitoring probe and the fault type; the network management equipment receives the alarm information, and determines the position of the fault according to the alarm information; and processing modes corresponding to the fault type and the position of the fault are found in a preset strategy library, and the network cell equipment is controlled to act according to the found processing modes. According to the network fault processing system provided by the invention, certain emergency treatment is carried out on the network cell equipment during network fault, which avoids the continuous influence of the fault on the operation of the packet transport network.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a system for handling network faults. Background technique [0002] Packet Transport Network (English: Packet Transport Network, referred to as: PTN) is the product of the combination of transport technology and Ethernet bearer technology, with packets as the transmission unit, mainly carrying carrier-class Ethernet services, compatible with time division multiplexing mode (English: Telemetric Data Monitor, referred to as: TDM), asynchronous transfer mode (English: AsynchronousTransfer Mode, referred to as ATM) and other comprehensive transmission technology business. [0003] In order to ensure the stable operation of the packet transport network, the network is usually monitored. There are two types of monitoring methods: active monitoring and passive monitoring. Active monitoring is to evaluate the service transmission performance of the network by actively initiating a sma...
