A method and device for collecting and processing network data

Abstract

The present application discloses a method and device for collecting and processing network data. The method includes: S1. The receiving-end collecting and processing unit receives a heartbeat message sent by the sending-end collecting and processing unit, and extracts the sending-end timestamp in the heartbeat message; S2. When the local When the difference between the time stamp and the time stamp of the sender exceeds the preset time difference threshold, confirm that the sender is abnormal by sending an exception request message; S3. Determine whether the receiver is the main collection and processing unit, if so, execute S4, otherwise execute S5 ; S4 , setting the LAN port corresponding to the sending end to an unavailable state through the receiving end; S5 , setting the receiving end as the main acquisition and processing unit, and setting the LAN port corresponding to the sending end through the receiving end to an unavailable state. It solves the technical problem that the existing technology cannot detect the fault caused by the hardware problem, the acquisition and processing unit operating system or the software problem, and then continues to output the data to the relevant LAN port, resulting in data loss or network disconnection.

Description

technical field [0001] The present application relates to the technical field of network data collection, and in particular, to a method and device for collection and processing of network data. Background technique [0002] Today, with the rapid development of communication technology, various network applications are developing rapidly, and network traffic is also showing explosive growth. In order to provide better network services and ensure a more secure network environment, it is necessary to collect, analyze and process network data through serial or parallel connection. Due to the variety of communication protocols and the ever-changing data formats, extremely high requirements are placed on the processing capability and stability of the acquisition and processing unit. [0003] In the existing acquisition and processing unit, the aggregation switching device usually judges whether the link with the acquisition and processing unit is normal through the electrical st...
