Title:
ROUTE DETECTION METHOD BASED ON TUNNELING TECHNOLOGY, AND ROUTING NODE AND CENTRAL SERVER
Document Type and Number:
WIPO Patent Application WO/2019/218786
Kind Code:
A1
Abstract:
A route detection method based on tunneling technology, and a routing node and a central server. The route detection method comprises: a first node sending a detection request message to an adjacent second node in the same group, and receiving a detection response message returned by the second node and comprising link delay and a packet loss rate; the first node sending a quality message regarding a link between the two nodes to a central server according to the link delay and the packet loss rate; and the first node comparing the link delay and the packet loss rate between the two nodes with a pre-set link delay threshold and a packet loss rate threshold, and if these two exceed the thresholds, sending a link routing query message to the central server, receiving a link routing response message sent by the central server, and modifying a routing table of this node according to the optimal link in the link routing response message, wherein the messages are all sent after tunnel encapsulation.
