Abstract

The invention belongs to the technical field of satellites, and particularly relates to a lightweight network middleware architecture system and a satellite communication method. The system comprises a lightweight network middleware cluster assembly and a ground control assembly which are connected with each other; the lightweight network middleware cluster assembly comprises a plurality of satellite nodes which are connected with one another and a satellite controller, network middleware obtained through a network virtualization technology is arranged in the satellite nodes, the network middleware is used for realizing network functions of the satellite nodes, and the network middleware comprises a plurality of independent function behavior characterization modules; the ground control component is used for creating, deploying and controlling the network middleware; and the ground control component is also used for sending compression and merging information to the satellite controller, so that the satellite controller merges and compresses behavior modules in the network middleware in the same satellite node or adjacent satellite nodes in the service chain. According to the invention, the processing time delay of the satellite network to the data packet can be reduced, and the processing rate is improved.

Description

technical field [0001] The invention relates to the field of satellite technology, in particular to a framework system of lightweight network middleware and a satellite communication method. Background technique [0002] With the rapid development of Internet technology, people have put forward higher requirements for satellite networks, expecting them to carry more business types, provide higher bandwidth, and have good scalability, reliability and flexibility. However, the current satellite network has the following problems: First, the functions of the satellite nodes are lacking. In order to provide different network services through the satellite network, it is necessary to deploy different types of network functions on the satellite, such as firewalls, load balancers, web page accelerators, etc. Most satellites only support simple forwarding functions, and more complex network functions are temporarily not supported. This has also resulted in the fact that the types ...
