One of the key components of communication networks, which determines the principles of their operation, are traffic routing protocols. The purpose of this article is to consider the possibility of using widely used dynamic routing protocols in LEO satellite communication systems. Based on the available publications, the analysis of the initial data was carried out and the conditions for the functioning of routing protocols in low-orbit satellite communication systems, as well as the basic requirements for such protocols, were formulated. The analysis of the functioning of the dynamic routing protocols in the given conditions is carried out. The disadvantages of the considered protocols are highlighted and characterized. The main conclusion of the article is the inexpediency of using the considered protocols in low-orbit satellite communication networks due to the high resource requirements and the insufficient speed of propagation of changes. The results can be used to substantiate technical solutions in the design of low-orbit satellite communication networks.
