Description

technical field

[0001] The invention belongs to the technical field of real-time capture, storage and retrieval of network traffic, and in particular relates to a distributed network traffic retrieval method and device. Background technique

[0002] In recent years, with the rapid development of the Internet, network bandwidth has increased dramatically, and the development of the Internet has brought more challenges to network security. Similar to surveillance cameras and surveillance video storage, query, and forensics equipment, real-time monitoring, storage analysis, and source traceability of network traffic have become a key method to ensure network security. In this way, network administrators can retrospectively analyze the abnormal network behavior and application communication data that have occurred, which is widely used in financial transactions, network forensics, network security and other fields.

[0003] For the field of real-time network traffic storage and...
