Abstract

The embodiment of the invention discloses an intelligent backbone network management scheduling system and method based on segment routing. The system comprises a backbone network centralized control device, at least two supplier edge routers and at least two customer edge routers. Aiming at each supplier edge router, the supplier edge router is used for acquiring dynamic routing information of a user through a corresponding customer edge router when monitoring that the user accesses, determining a customer dynamic route according to the dynamic routing information and sending the customer dynamic route to the backbone network centralized control device; the backbone network centralized control device is used for determining path configuration information according to the received client dynamic route and the current backbone network node path information, wherein the path configuration information is used for data transmission. And uniformly planning the path of the edge network where the client is located and the path of the backbone network so as to facilitate data transmission. The efficiency of network management is improved, and real-time adjustment of network scheduling is realized. Paths are calculated automatically, cost is reduced, and efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a segment routing-based intelligent backbone network management and scheduling system and method. Background technique [0002] The existing backbone network technology is gradually transitioning from Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) to SRv6. MPLS implements label distribution by adding Label Distribution Protocol (LDP) to the original interior gateway protocol (interior Gateway Protocols, IGP). Since LDP does not have traffic engineering, resources based on traffic engineering expansion are added. Reservation Protocol (Resource ReServation Protocol-Traffic Engineering, RSVP-TE). Because RSVP signaling is very complex, the signaling for MPLS technology to maintain the entire network is complex and the configuration tasks are heavy. At the same time, it consumes a lot of device resources and affects forwa...
