Link state maintenance method and device

Abstract

The present invention provides a link state maintenance method and device, which selects at least one of multiple upper-level nodes corresponding to the current node to establish a communication link according to the priority; broadcasts the first dynamic route to the corresponding upper-level node through the communication link Information: receiving the second dynamic routing information broadcast by the corresponding upper-level node through the communication link and broadcasting to the lower-level node communicating with the current node. Among them, in the static configuration, the lower-level node selects the upper-level node according to the priority, and supports the situation that the lower-level node corresponds to multiple upper-level nodes at the same time, so that when the upper-level node is abnormal, the information can be transmitted through other upper-level nodes, avoiding transmission interruption and improving transmission reliability. meet application requirements. In addition, the link state maintenance of non-adjacent nodes is supported through dynamic routing state broadcast, further improving transmission reliability.

Description

technical field [0001] The invention relates to the field of Internet data transmission, in particular to a link state maintenance method and device. Background technique [0002] With the continuous development of the Internet, the application range of data transmission systems is becoming wider and wider. Banks, catering, logistics and other industries have developed supporting data transmission systems to achieve hierarchical and unified management of data. Among them, the existing data transmission The system mainly adopts a converged architecture, such as figure 1 As shown, multiple lower-level nodes converge layer by layer. Among them, the number of upper-level nodes is less than the number of lower-level nodes. The lower-level nodes send monitoring data messages to the upper-level nodes to realize data summary transmission, and the upper-level nodes send monitoring and management messages to the lower-level nodes. , to achieve data delivery and node management.

Problems solved by technology

[0005] In view of this, the present invention provides a link state maintenance method and device, electronic equipment, and a computer-readable storage medium. During static configuration, a lower-level node selects a higher-level node according to a priority, and supports a situation where a lower-level node corresponds to multiple upper-level nodes at the same time. , so that when the upper-level node is abnormal, the information can be transmitted through other upper-level nodes to avoid transmission; in addition, the maintenance of the link status of non-adjacent nodes is supported through dynamic routing status broadcasting, which solves the problem that the upper-level nodes cannot know the non-adjacent nodes and their relatives in the existing transmission scheme. The connectivity status of the adjacent upper-level node leads to the problem of abnormal transmission
