Perception, computing, and storage integrated space intelligent network architecture

Abstract

The invention discloses a perception, computing, and storage integrated space intelligent network architecture. The space intelligent network architecture is addressed by an equipment global identifier (E-GUID) and IP, thereby realizing the compatibility with the IP network; and the data transmission integrates the content perception, thereby realizing the cross-layer collaborative service of theapplication and the network, improving the fact that the traditional IP address is only used as a single function of address identification, and breaking through the limitation in a space-based network. At the same time, the space router can have the content sensing capability, and retrieves content in the content storage, thereby realizing the intranet storage transmission mode, breaking the end-to-end transmission mode of the traditional IP, and effectively reducing the transmission delay, the resource, and the energy consumption. The content security is introduced in the network packet; andthe self-authentication mechanism of the network layer data is constructed, which makes it possible to implement the data trust and the integrity verification in the transmission process; and the end-to-end security mechanism of the traditional IP network data is broken.

Description

technical field [0001] The invention relates to the field of satellite networking of computer network technology, in particular to a space intelligent network architecture integrating perception, computing and storage. Background technique [0002] With the rapid development of Internet technology, traditional terrestrial network solutions based on the TCP / IP architecture have been able to better meet the communication needs of the terrestrial Internet. However, different from traditional terrestrial networks, space-based networks have the characteristics of heterogeneous nodes, highly mobile nodes, time-space changes in links, long space distances, and large transmission delays, which determine that space-based networks will face dynamic networking and transmission Intermittent challenges. Due to the limitation that the traditional ground network based on the TCP / IP architecture only takes simple transmission as the core function, it is difficult to cope with the above-men...

AI Technical Summary

Problems solved by technology

This network system can solve the problems of intermittent connection and long delay to a certain extent, but due to the difficulty of effectively sensing the network status and the lack of unified content identification, there is a problem of low routing efficiency

Moreover, the DTN network lacks a mature congestion control and flow control mechanism, making it difficult to deal with network congestion.

In addition, the security mechanism of the DTN network is still under research and improvement, and there are certain limitations in the security of data transmission
