Problems solved by technology

When the network scale increases to a certain level, the accuracy of finding error messages and judging whether there is a problem with network equipment based on experience based on error messages will be greatly reduced. Solving the problem of error messages requires multiple attempts, and each attempt It may cause a complete interruption of the network and affect the normal communication of the network.
Especially for a large-scale Internet network, it is more difficult to find error messages and determine specific network devices that have problems based on experience

Embodiment 1

[0124] When this embodiment performs packet error detection, the detected network may be a network composed of one or more network devices, and the network device may be a router or a switch. In this embodiment, the detected network is a single network device as an example. Including a first interface and a second interface; this embodiment first distinguishes the inbound packets and outbound packets of the first interface and the second interface of the network device, and specifically, can be copied from the first interface and the second interface into the implementation of the present invention For example, in the message of the network device, the message transmitted by the network device in the embodiment of the present invention is copied from the first interface and the second interface; interface, distinguish the duplicated incoming packets and outgoing packets through the set incoming interface and outgoing interface and transmit them to the device for packet error de...

Embodiment 2

[0144] The device for packet error detection in this embodiment includes an acquisition unit and a matching analysis unit, and the acquisition unit is connected to each interface of the detected network; the detected network may be one network device or a network composed of two or more network devices ; Figure 4 It is a flow chart of the method of the second embodiment of the present invention, such as Figure 4 shown, including:

[0145] Step 400, the obtaining unit obtains and distinguishes the incoming message and the outgoing message transmitted by the detected network;

[0146] Step 401, the acquiring unit extracts the feature value of the acquired inbound message and the part that should not change in the outbound message;

[0147] Step 402, the acquisition unit sends the feature value extracted from the part that should not change in the incoming message and the feature value extracted from the part that should not change in the outbound message to the matching anal...

Embodiment 3

[0152] In order to clearly state the present invention, in this embodiment, the method of the present invention is described clearly and in detail by taking area A, area B, and area C transmitting packets through the detected network as an example. Figure 5 It is a schematic diagram of the network topology of the third embodiment of the present invention that the packets pass through the detected network, such as Figure 5 As shown, for area A, the message flow includes from area A to area B, area A to area C, area B to area A, and area C to area A; Further positioning of the packet flow direction can narrow the matching range during packet detection and improve the efficiency of packet error detection. The packet flow direction can be determined by including the source address and destination address, or configuration information.

[0153] In a non-Network Address Translation (NAT) scenario, taking the packet flow direction containing the source address and the destination ...

Abstract

The invention discloses a message error detection method and device. The method comprises the steps of obtaining and distinguishing incoming messages and outcoming messages transmitted by a detected network; and matching the parts which should not be changed in the incoming messages and the outcoming messages and determining whether errors occur in the messages or not, wherein the detected network is the network composed of one or more network devices. According to the method provided by the invention, the incoming messages and the outcoming messages are matched and whether the errors occur in the messages is determined, so the message error detection is carried out on the detected network; and further the network devices are adjusted according to a message error detection result, the normal communication of the detected network is timely adjusted, and the normal communication of the network is ensured.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a method and device for realizing message error detection. Background technique [0002] In the carrier network, enterprise network, and Internet network and other networks, there are a large number of network equipment involved, such as: Broadband Remote Access Server (BRAS) equipment, access / core router equipment, access / core switch equipment , Layer 3 switch equipment and various optical network equipment. These network devices run the Protocol (IP) network protocol for interconnection between networks, and by interconnecting each other, a world based on the IP network protocol is constructed. Some packet fields should not be changed when packets are transmitted through network devices, but packet errors may occur during packet transmission. Taking an enterprise network as an example, assume that there are area A, area B, and area A. The communication link with area...
