The communication method includes: receiving, by a first port of a switch, a first data packet from a first external device; packing the first data packet with a first VLAN ID corresponding to a first path to generate a second data packet; receiving, by a first PLD, the second data packet from a third port of the switch; filtering, by the first PLD, the second data packet according to a first filtering rule; in response to the second data packet being matched with the first filtering rule, overwriting the first VLAN ID by a second VLAN ID corresponding to a second path to generate a third data packet; and transmitting, by the first PLD, the third data packet to a second port of the switch via the second path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method for one-way transmission based on VLAN ID and switch device using the same","description":"A communication method and a switch device for one-way transmission based on VLAN ID are provided.
