Problems solved by technology

[0018] In short, the problems existing in the existing technology are: the dynamic changes of the topology structure caused by the relative movement between the various platforms of the network are coupled, the dynamic changes of the topology in a single autonomous domain will affect the structure of the entire network, and the network nodes cannot be "plug and play". ", network management control is inefficient

Abstract

The invention discloses a spatial information network isomerism dynamic networking method based on a layered autonomous area. The method includes the following steps that according to components and functions of all parts in the whole spatial information network, a spatial information network system structure is set up; according to the properties, the functions, the zone positions and the requirements, all nodes in the network are divided into different layered autonomous areas with independent networking routing strategies; boundary nodes are selected to separate a control link from a service link and the inter-domain control information transmission and the intra-domain control information transmission are separated; an intra-domain sub-layer which is in line with international standards and an inter-domain sub-layer which has the same protocol and functions on all the nodes are set up to form a layered autonomous area model network protocol stack frame. According to the spatial information network isomerism dynamic networking method based on the layered autonomous area, coupling is little, the network nodes are plugged when needed, and the network managing control efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of networking of spatial information networks, in particular to a method for heterogeneous dynamic networking of spatial information networks based on hierarchical autonomous domains. Background technique [0002] With the development of aerospace technology, more and more satellites are deployed in space, which greatly expands the communication range. However, the traditional communication method using a single satellite as a relay and using a satellite-ground link has been difficult to meet practical applications, and the space-space-ground integrated space information network covering satellites, lift-off platforms and ground networks has become the development trend of space communication networks. [0003] The space information network is a network system that acquires, transmits and processes space information in real time using space platforms (such as geostationary satellites or medium- and low-orbit...
