Problems solved by technology

However, the existing routing algorithms have the following deficiencies: (1) There is only one final path for calculation, and the backup path is not considered
When a link on the main path fails, the service is interrupted, the recovery speed is slow, and the service cannot be better secured.
(2) The granularity of business division is too coarse, only streaming media stream and non-streaming media stream are divided, which does not meet the needs of various business types

Abstract

The invention discloses an SR-based service routing calculation method. The SR-based service routing calculation method comprises the following steps: S1, calculating different constraint paths of different services; S2, scheduling existing topological network resources; S3, calculating a main path and a plurality of standby paths of the service based on the whole network topology; and S4, updating and checking the multi-thread maintenance path configuration. The method has a complete main path and a complete standby path, the service stability is guaranteed, and when the main path breaks down, millisecond-level switching to the standby path can be achieved; the main path and the standby path are not intersected, and even if any link of the main path fails, the use of the standby path is not influenced, and the guarantee capability of the standby path is amplified; customized constraint paths from different sources ip to different purposes ip is realized based on the service definition of the ip address end and the SR; constraint paths of services and threads are maintained in real time for all the services and threads, and data verification consistency is guaranteed.

Description

technical field [0001] The invention relates to a service routing calculation method based on SR (Segment Routing, segment routing), which belongs to the technical field of communication. Background technique [0002] With the advent of the Internet age, the number of various network services has exploded. The user's demand for the network continues to increase, resulting in the need for continuous upgrading of the network to meet the growing user demand. Therefore, it is imminent to improve network performance, increase network reliability, and optimize network architecture. Traditional IP network routing information needs to be maintained by each node. There is no unified controller for traffic scheduling. It has disadvantages such as poor scalability, poor stability, and low link utilization. Obviously, it cannot meet the existing network needs. Therefore, software-defined networking (SDN) was born, which separates the control plane and forwarding plane, decouples hardwa...
