Patent number: 11425029Abstract: In an internal network monitoring method for monitoring an internal network, a specified network packet, which is scheduled to be transmitted via a specified path, is inspected. A packet characteristic is extracted from a data link layer of the specified network packet. The specified network packet is directly transmitted via the specified path if the packet characteristic does not comply with a preset condition. The specified network packet is redirected to be transmitted via another path different from the specified path or mirroring the specified network packet to create a mirror packet if the packet characteristic complies with the preset condition.Type: GrantFiled: July 2, 2020Date of Patent: August 23, 2022Assignee: QNAP SYSTEMS, INC.Inventors: Hua-Chung Kung, Shih-Chan Huang
