Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The implementation method of the virtual network interface based on the master-slave heterogeneous data transmission module of the present invention, its steps are:
[0020] (1) Form a virtual network interface: abstract the master-slave heterogeneous wireless data transmission module into a virtual network interface, and register the interface in the communication system; the virtual network interface behaves as a general physical network interface to the network layer, and has a data link Road layer address and network layer address related parameters; for the data transmission module, it is oriented to a specific data transmission device, using device drivers to interact with it;
[0021] (2) Send network layer data unit: the virtual network interface slices and sends after receiving the network layer data unit; first reads ...

The invention discloses a method for realizing a virtual network interface based on a master-slave heterogeneous data transmission module. The method comprises the following steps of: (1) forming the virtual network interface, namely abstracting the master-slave heterogeneous wireless data transmission module into the virtual network interface; (2) transmitting a network layer data unit, namely slicing the network layer data unit after the virtual network interface receiving the network layer data unit, and transmitting the sliced network layer data unit; and (30 receiving a data frame of the data transmission module, namely buffering and reassembling the data frame of the data transmission module after the virtual network interface receives the data frame of the data transmission module, and submitting the data frame to a network layer. By the method, the data transmission module is virtualized into the network layer interface, thereby improving the interoperability of inter-satellite communication and bringing convenience to the transmission and distribution of inter-satellite data.
Description
technical field [0001] The invention mainly relates to the field of inter-satellite communication in the field of small satellite clusters, in particular to a method for realizing a virtual network interface based on a master-slave heterogeneous data transmission module. Background technique [0002] The concept of satellite network was proposed in the last century. Up to now, some communication technologies based on ground network can no longer meet the needs of users for various communication services. The different needs of business and military also promote the development of satellite communication in the direction of networking. At present, most of the communications between satellites and ground stations and between satellites are carried out by way of circuit switching. Although the communication between satellites and ground stations based on packet switching has been realized, the communication between satellites based on packet switching has not yet been realized....
