Device and method for establishing private LAN using satellite network

Abstract

A device and a method for using a satellite network to establish a private local network are provided, which uses GRE tunnel to facilitate the satellite network and a ground local network to communicate with each other. The device comprises a master station unit (1), a satellite receiving and emitting unit (2), a proximal router (4), and an auxiliary unit (3); wherein, the proximal satellite receiving and emitting unit (2) of one end carries on satellite signal transmission to the remote satellite receiving and emitting unit (2) of the other end, the proximal router (4) is connected with the proximal satellite receiving and emitting unit (2) through a network, and at the same time, the proximal satellite receiving and emitting unit (2) is connected with the auxiliary unit (3) through a cable and a distributor. The invention has the advantages that the satellite network and the ground local network (5) are well integrated together, thus enabling the satellite network to be used flexibly, and leading the satellite network to be used in the currently most popular internet based on IP. The invention greatly improves the compatibility of the satellite network, and the technology used in the internet can also be used in the satellite network.

Description

technical field [0001] The invention uses the GRE tunnel to make the satellite network and the ground local area network communicate with each other, and belongs to the technical field of the integration of wireless network communication and wired network communication. Background technique [0002] Due to the lack of terrestrial communication bandwidth resources in many areas of my country at this stage, it is impossible to fully support streaming media transmission. At the same time, Internet operators implement restrictive online broadcasting services in order to prevent network broadcasting storms; Occupied, many policies are set to restrict video applications. But some, such as distance classroom teaching, are characterized by a large amount of downlink information on the network, and most of them are mainly images and sounds. Obviously, the existing terrestrial Internet cannot support it well, and the above-mentioned problems can be solved precisely through satellite c...

Obviously, the existing terrestrial Internet cannot be well supported, and the above-mentioned problems can be solved precisely through satellite channels

However, due to the reason of the DVB-RCS system, when the satellite communication device is issued to the customer, a fixed IP address has been allocated. These addresses are the addresses used in the satellite network. to difficulty
