Network data acquisition and processing method and device

Abstract

The invention discloses a network data acquisition and processing method and device, and the method comprises the steps of: S1, enabling a receiving end acquisition and processing unit to receive a heartbeat message transmitted by a transmitting end acquisition and processing unit, and extract a transmitting end timestamp in the heartbeat message; S2, when the difference between the local timestamp and the timestamp of the sending end exceeds a preset time difference threshold value, sending an exception request message to confirm that the sending end is in an exception state; S3, judging whether the receiving end is a main acquisition processing unit or not, if so, executing the step S4, and otherwise, executing the step S5; S4, setting an LAN port corresponding to the sending end to be in an unavailable state through the receiving end; and S5, setting the receiving end as a main acquisition processing unit, and setting the LAN port corresponding to the sending end to be in an unavailable state through the receiving end. The technical problem that in the prior art, faults caused by hardware problems, collecting and processing unit operating systems or software problems cannot be detected, and then data continues to be output to related LAN ports, so that data loss or network disconnection is caused is solved.

Description

technical field [0001] The present application relates to the technical field of network data collection, in particular to a method and device for network data collection and processing. 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 connection or parallel connection. Due to the variety of communication protocols and ever-changing data formats, this places extremely high requirements on the processing capability and stability of the acquisition and processing unit. [0003] In the existing collection and processing unit, the aggregation and switching device usually judges whether the link with the collection and processing unit is normal through the electrical ...
