Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0070] figure 1 What is shown is a schematic flowchart of a method for collecting network topology information provided by an embodiment of the present invention. Such as figure 1 As shown, the method for collecting network topology information is applicable to the network layer of a local node in a network topology structure. The network topology may be an LLN network, and in the LLN network, except for the root node, each node has the same physica...

Abstract

The embodiment of the present invention provides a method for collecting network topology information, a method for uploading network topology information, a method for repairing routes, a method for uploading repairing information for routes, a computer device, and a computer-readable storage medium, which solves the problem of excessive increase in existing route repair methods. control overhead and fix latency issues. The network topology information collection method is suitable for a network layer of a local node in a network topology structure, and the network topology information collection method includes: determining the neighbor node according to the topology relationship between the neighbor node and the local node and storing the node type of the neighbor node in the local node.

Description

technical field [0001] The present invention relates to the technical field of Low Power and Lossy Networks (LLN), in particular to a method for collecting network topology information, a method for uploading network topology information, a method for repairing routes, a method for uploading repair information for routes, computer equipment and computer readable storage medium. Background technique [0002] A low-power lossy network (LLN network) is a multi-hop network (usually referred to as a wireless network) composed of nodes with low power consumption, and the links between nodes are not guaranteed to be reliable. The LLN network has the characteristics of no need for infrastructure support, low power consumption of nodes, and link reliability affected by the environment. In the LLN network, all nodes have equal logical status, have the functions of host and router at the same time, and can forward data. They realize data communication with other adjacent or non-adjace...
