Latest Patents

Choi is credited with 1 patent: “Method for Implementing Zero Trust Role-Based Microsegmentation Based on Network Switch and Network Controller and Access Switch Using the Same.”

The invention describes a network controller registering a network device in a segment based on its asset information, then sending the segment ID to an access switch. The switch assigns that ID as metadata to the device’s MAC address using VACL and applies resource-access rules using IACL. This approach enables network access to be controlled according to the device’s assigned segment.

Career Highlights

The available information connects Choi’s patent activity with Piolink, Inc. His documented invention addresses the coordination of network controllers and switches to implement segmented, zero-trust access controls.

Collaborations

Choi’s listed coworkers include Nam Pyo Kim and Jae Young Park. The patent description identifies roles for a network controller and an access switch, but the supplied information does not specify the coworkers’ contributions to the invention.

Conclusion

Junnyung Choi’s documented patent focuses on applying role-based microsegmentation through network infrastructure, linking device asset information to segment-specific access controls.
