Addressing and routing method suitable for global low-orbit satellite constellation

Abstract

The invention discloses an addressing and routing method suitable for a global low-orbit satellite constellation. Firstly, a global low-orbit satellite constellation system organization structure is divided, then single-system multi-parallel-address space independent addressing is carried out, and finally a global low-orbit satellite constellation route is built. According to the method, the samesystem is divided into a plurality of address spaces through a single-system multi-parallel-address space independent addressing method, and independent addressing is performed, so that a complex useraddress management problem is decoupled from the low-orbit satellite constellation, and the problems of port / network segment matching and user address management are solved; compared with the prior art, task requirements of a global low-orbit satellite constellation system and capability characteristics of a satellite system are fully considered; and the method is simple and efficient, and has engineering feasibility.

Description

technical field [0001] The invention relates to an addressing and routing method applicable to global low-orbit satellite constellations, belonging to the field of satellite communication. Background technique [0002] The global low-orbit satellite constellation system consists of multiple satellites distributed in multiple orbits based on the inter-satellite link interconnection. Compared with the ground network, there are significant differences between the system and the ground network. At the same time, it also brings a series of design problems, which are concentrated in the following aspects Aspects: [0003] 1) The form of the constellation transmission link is a wireless link, which brings a greater packet loss rate, transmission delay, etc., and completely changes the network organizational structure. Each port of the ground routing and switching equipment corresponds to a network segment, usually connected to a specific type of network equipment; while in the sat...
