Embodiment Construction

[0026] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0027] figure 1 is a schematic block diagram of a satellite communication ground system 100 according to an embodiment of the present invention.

[0028] like figure 1 As shown in , the satellite communication ground system 100 of the present invention includes a terminal subsystem 102 , a gateway subsystem 104 and a network management subsystem 106 . Terminal subsystem 102 uses virtual local area network ("VLAN") technology for network configuration and includes multiple communication terminals, such as Figure 2-4 The communication terminal R shown in. In one embodiment, the communication terminal can be such as figure 1 One or more computer PCs shown, they can be configured in different VLANs through VLAN technology, for example figure 1 VLAN10 and VLAN20 shown in , and can be connected to a very small aperture terminal ("VSAT") through a la...

Abstract

The invention provides a ground system of satellite communication. The system comprises a terminal subsystem, a gateway station subsystem, and a network management subsystem; the terminal subsystem performs network configuration by adopting a virtual local area network technology and comprises multiple communication terminals; the gateway station subsystem performs network configuration by using QinQ network technology so as to conveniently receive and send data packets from communication terminals, and the data packets of the communication terminals are transmitted through the satellite; thenetwork management subsystem is configured to execute a network management operation on the satellite communication ground system. Through the satellite communication ground system provided by the invention, the satellite user networks can be greatly increased and the mutual interference is avoided through the VLAN and the QinQ technology along the increasing the amount of the satellite user.

Description

technical field [0001] The present invention relates generally to the field of satellite communications. More particularly, the present invention relates to terrestrial systems for geostationary satellite communications. Background technique [0002] With the wide application of switching technology in Ethernet, the technology of virtual local area network ("Virtual Local Area Network", VLAN) based on switches has also been greatly developed. VLAN is a logical group composed of some LAN segments and has nothing to do with physical location. Networking with VLAN technology has the following advantages: [0003] ①Many LAN protocols use broadcasting to provide network information, and broadcast frames will reach all hosts on the network. Hosts must process these broadcast frames, thereby reducing network performance. Dividing VLANs can isolate a large broadcast domain into multiple smaller broadcast domains. In this way, the broadcast frame sent by the host can only be tra...
