Abstract

The invention discloses a satellite network acceleration system based on a virtual machine, which belongs to the technical field of satellite communication. The system includes a load balancing module, a virtual machine management control module, and a physical computing processing unit; the load balancing module is connected to the ground equipment through the LAN port, connected to the satellite network through the WAN port, communicates with the physical computing processing unit through the service port, and controls The virtual machine management control module communicates with the virtual machine management control module; the virtual machine management control module communicates with the physical computing processing unit through the control port; the virtual machine management control module dynamically runs one or more virtual machines in the physical computing processing unit as required machine. The present invention uses virtualization technology to abstract computing physical resources, so that users can use these resources in a better way than the original configuration. The invention is suitable for being deployed in a new type of satellite ground station, and can adapt to the characteristics of multi-connection, large bandwidth and high-capacity communication faced by future satellite communication.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite network acceleration system based on a virtual machine. Background technique [0002] The satellite communication channel has the characteristics of long delay and high bit error. The transmission efficiency of the traditional TCP protocol is very low under this channel condition, resulting in a waste of satellite channel bandwidth. [0003] The performance flexibility of traditional IP acceleration is insufficient. After the ground station is built, the performance of its protocol acceleration is basically finalized: only by upgrading the hardware can the processing performance be improved. Moreover, even if the performance level is improved through hardware upgrades, its performance is still limited, and it is impossible to elastically improve performance in real time. [0004] At present, the design of the new large-scale ground station IP accelera...
