Patent 11784963 was granted and assigned to Huawei on October, 2023 by the United States Patent and Trademark Office.
A method, a device, and a system for network address translation traversal are provided. The method is performed by a system in which a first terminal communicates with a second terminal. The first terminal is in a network constructed by a first NAT device, the second terminal is in a network constructed by a second NAT device, and the first NAT device is different from the second NAT device. The method implements NAT traversal through bidirectional dynamic detection of TTL values at both ends of the NAT traversal, to resolve a problem of low NAT traversal efficiency.
