Title:
NAT TRAVERSAL METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/000633
Kind Code:
A1
Abstract:
A network address translation (NAT) traversal method and device. The method comprises: sending, by a public network server, a first notification message to a first host, wherein the first notification message is used to notify the first host to monitor a first port corresponding to the first host; when the first host completes monitoring the first port, sending, by the public network server, a second notification message to a second host, wherein the second notification message is used to notify the second host to establish a connection with a first host; sending, by the public network server, a third notification message to the first host, wherein the third notification message is used to notify the first host to stop monitoring the first port and notify the first host to establish a connection to the second host. The embodiments of the present invention address the problem in the related art in which unsupported address reuse in a protocol stack makes it impossible to send a hole-punching connection packet and initiate monitoring simultaneously at the same port, thus increasing a hole-punching success rate.
