Segment routing in data transmission networks

Abstract

A telecommunications network is a group of nodes and connections between them, the main purpose of the organization of which is to transmit information for a certain period of time. Since the network is only a tool, the technologies of applying this tool to the transmitted information may vary, i.e. the algorithms for transmitting information between nodes, choosing the order of transmission, building routes from one node to another may differ depending on the principles of network organization and the goals of information transmission. One of these technologies is Segment Routing (SR), created in order to improve the methods of working with the network, its vision and eliminate the problems inherent in the technologies previously used on these networks. Segment routing represents an important evolutionary step forward in the design, management and operation of modern data transmission networks. An important mechanism for optimizing the use of network resources is the load balancing mechanism. Data on the status of nodes and data transmission channels in the network can significantly facilitate the task of ensuring load balancing in the network. This article is devoted to an overview of segment routing technology, consideration of existing prerequisites for more active implementation and use of this technology.
