Problems solved by technology

The existing redundant backup scheme adopts one-to-one VNF backup method, which will introduce additional overhead, insufficient consideration of resource sharing, resulting in low resource utilization, and ignores the QoS requirements of the service, resulting in the backup scheme not being able to Meet the QoS requirements of the service

Embodiment Construction

[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0032] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0033] The present invention proposes a QoS-aware service chain redundancy backup method and system, which combines the QoS requirements with the backup process, and considers the sharing of backup network functions, thereby reducing excessive backup of VNFs and improving the resource utilization efficiency and efficiency of the service chain. Reliability, and a failure handling mechanism is also proposed to solve the probl...

Abstract

The invention discloses a QoS-aware service chain backup method and system. The service chain backup method comprises the following steps: a QoS-aware service chain backup problem is subjected to mathematical modeling, and QoS constraint conditions and a target function of the service chain backup problem are set; a service chain with the reliability lower than a reliability threshold is subjectedto backup of a virtual network function according to the QoS constraint conditions of the service chain backup problem, if the to-be-backed up virtual network function exists, an existing backup virtual network function is preferentially selected to serve as a shared backup, and if the to-be-backed up virtual network function does not exist, a new backup is created; and a final service chain backup scheme is determined according to the QoS constraint conditions and the target function of the service chain backup problem. According to the QoS-aware service chain backup method and system, the QoS requirement is combined with the backup process, the sharability of the backup network function is considered, therefore, excessive backup of the VNF is reduced, and the resource utilization efficiency and reliability of the service chain are improved.

Description

technical field [0001] The invention relates to the field of multi-service bearer networks, in particular to a QoS-aware service chain backup method and system. Background technique [0002] With the help of standard IT virtualization technology, network function virtualization (NFV) realizes the flexible loading and instantiation of network function software by using industrial standard large-capacity servers, storage and switches to carry various software-based network functions (NF). This reduces the complexity of service deployment. Decoupling software-based network functions from dedicated hardware devices enables virtualization of network functions and sharing of hardware resources. At the same time, NFV technology also provides operators with management and orchestration functions to achieve flexibility and agility in network deployment, and improves the unification and generalization of network equipment. In NFV, end-to-end services are realized by traversing an or...
