A Method of Information Center Network Architecture for Manned Deep Space Exploration

Abstract

An information center network architecture method for manned deep space exploration. According to the space area and node communication range, according to the connection plan, the aggregation node in each domain can be selected as the domain server of the domain. It is responsible for internal information management in the domain and external Responsible for building inter-domain transmission links to realize cross-domain data transmission; through this domain server, each domain forms a top-level domain topology network for networking communication, and data and information are synchronized and transmitted between these top-level domains; each The data transmission and network management in the top-level domain are realized through the concept of hierarchical domains; according to the longitude, latitude and altitude geographic information spatial position, the top-level domain or domain space is subdivided into multiple second-level domains, and each second-level domain also has a domain Servers, all domain servers are interconnected to form the backbone transmission network of the entire network and tree-like network topology management, which solves the problems of flexible networking and delay tolerance between domains for manned deep space exploration in the future.

Description

technical field [0001] The invention relates to the field of space information network, in particular to an information center network architecture method for manned deep space exploration. Background technique [0002] With the development of aerospace technology, human exploration of deep space has never stopped. my country's deep space exploration activities started in 2004. After more than ten years of rapid development, it started from the moon and moved towards a new step of comprehensive development. It is expected to complete the "circling", "falling" and "returning" lunar exploration projects before 2020 In three steps, the Mars exploration mission was launched in the same year, opening a new chapter in deep space exploration. [0003] The current deep space network structure presents the characteristics of few nodes and single communication services. In this case, delay tolerant networks (Delay Tolerant Networks, DTN) can better meet communication needs and solve l...
