Problems solved by technology

When the network is initially opened, the parameters can only be copied to each node manually, the efficiency of manual copying is low, and when the nodes are scattered geographically, files must be transferred by means of a fixed network
The method of file transfer based on routing needs to be completed with the help of distribution software when the basic network is opened and the route is reachable. It cannot be used for the initial opening of the network, and the dependence on routing is too high

Embodiment Construction

[0018] In order to realize the parameter distribution function of the private network, the following three aspects need to be dealt with.

[0019] The realization and improvement of the flooding algorithm can reduce the resource waste of flooding messages on the narrowband satellite broadcast channel. The specific steps are implemented as follows:

[0020] 1. The nodes in the wired connection area adopt the basic flooding algorithm

[0021] 2. Each node forwards a message to a neighbor node, and if it receives the same message from a certain interface, it will not forward the same message to the interface again.

[0022] 3. The node connected to the satellite channel and the channel is normal sends a satellite channel notification message to the parameter distribution source node

[0023] 4. The parameter distribution source node selects the node that first receives the satellite channel notification message as the satellite channel distribution node

[0024] 5. The paramet...

Abstract

The invention discloses a parameter distribution method based on a flooding mechanism. The method comprises that parameter distribution within an area is completed in a basic flooding algorithm, nodes connected to a satellite channel notify a distribution source node but not forward messages to the satellite channel at first, and the distribution source node selects a node which returns at first and forwards the messages to other areas via the satellite channel. The node is started and then requests a parameter file version from the network, the distribution source node returns a confirmation message of the parameter file version, and other nodes substitute replies after receiving the confirmation message. When versions are inconsistent, the node requests a parameter file from the neighbor, and nodes in consistent versions distribute parameters to nodes in inconsistent versions. The method supports cross-area network parameter distribution, IP messages can be transmitted via physical links instead of fixed network transmission, manual copy or route intercommunication, narrowband broadcasting-satellite channel resource is saved to the largest degree, network opening time is greatly reduced, and the network opening efficiency is improved.

Description

technical field [0001] The invention relates to a parameter distribution method based on a flooding mechanism, which is suitable for a dedicated network including a narrowband satellite broadcast channel. Background technique [0002] The parameter distribution methods currently used by the private network include manual copying and file transfer based on routing. When the network is initially opened, parameters can only be copied to each node manually, and the efficiency of manual copying is low. When the nodes are scattered geographically, files must be transferred through a fixed network. The method of file transfer based on routing needs to be completed with the help of distribution software when the basic network is opened and the route is reachable. It cannot be used for the initial opening of the network, and the dependence on routing is too high. [0003] There is an urgent need for a method that can automatically distribute parameter files to each node through the ...
