The invention relates to a spatial information
network architecture. The spatial information
network architecture comprises a ground information port, a data forwarding layer and a space-based
backbone network; the ground information port is connected with the data forwarding layer, is connected with the space-based
backbone network through the data forwarding layer and is used for executing a user task request according to a received flow table; the data forwarding layer is composed of at least one
satellite selected from a
medium earth orbit satellite and a
low earth orbit satellite and is used for receiving the flow table, calling resources to execute the user task request, performing
data transmission and forwarding according to the flow table; the space-based
backbone network comprises at least one
geostationary orbit space satellite, a controller in the
geostationary orbit space satellite allocating resources for the task request and issuing the flow table; and the ground information port and the space-based backbone network together form a double-backbone
control system. According to the spatial information
network architecture of the invention, the global coverage characteristics of the GEO (
geostationary orbit) satellite and the computing power of a ground
base station are effectively combined, and the spatial information network can obtain
route forwarding strategies in real time, allocate resources and nodes reasonably according to tasks and improve
resource utilization rate and node cooperation ability.
