Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The flow chart of the method for suppressing forwarding in the mesh satellite network of the embodiment of the present application, such as figure 2 shown. Specifically, including steps:

[0040] (1) Preamble step: sending the routing terminal mapping table to the controlled network element, wherein the routing terminal mapping table includes a mapping relationship between routes and corresponding site IDs.

[0041] (2) Generate an undirected resource allocation graph with node weights according to resource nodes and network element information. The resource node includes device ID, channel number, bandwidth, and frequency information of both sending and receiving parties; the network element information includes network element forwarding weight, and the planning of the weight is set according to the application scenario.

[0042] (3) Find all link resour...

Abstract

The invention provides a method and device for suppressing forwarding in a mesh satellite network. The method includes: generating a node-weighted undirected resource allocation graph according to resource nodes and network element information; finding all link resource paths from the undirected resource allocation graph to generate an original path tree; generating the minimum resource allocation graph for each network element tree; according to the minimum resource tree, pruning the original path tree to obtain the information set that needs to be suppressed from forwarding; according to the need to suppress the information set from forwarding, the service center discards the corresponding data message. The device includes: sequentially connected: a mapping module, an allocation graph module, an original path tree module, a resource tree module, a pruning module, and a suppression module. The implementation of the present invention can realize the elimination of repeated data, effectively avoid the problem of overcollection of data in the mesh satellite network, and reduce waste of resources.

Description

technical field [0001] The invention relates to satellite communication, in particular to a method and device for suppressing forwarding of a mesh satellite network. Background technique [0002] In a mesh satellite network composed of one-send-multiple-receive devices, the following figure 1 scene shown. [0003] In this scenario, since each device has only one transmit channel, multiple receiving devices share the same channel, then, figure 1 There are two physical links for business data from business terminal station 1 to business terminal station 2: one is a double-hop link from business terminal station 1 to business center, and from business center to business terminal station 2; Single-hop link from terminal station 1 to service terminal station 2. At this time, the service terminal station 2 will receive two identical service data from the service terminal station 1 . This not only wastes bandwidth resources, but also may bring risks to service transmission due ...
