Method and device for deploying SFC service chain, and medium

Abstract

The embodiment of the invention discloses a method and device for deploying an SFC service chain, and a medium, and the method comprises the steps: constructing a corresponding number of virtual machines on a network card according to the number of service processes carried in a virtualization instruction; and configuring a corresponding number of virtual interfaces for the target virtual machineaccording to the function attribute corresponding to the target service process. Wherein the target virtual machine is any virtual machine in all the virtual machines; wherein the target service process is a service process corresponding to the target virtual machine, and the interface configuration of all the virtual machines can be completed according to the processing mode of the target virtualmachine, so that the smooth execution of each service process is ensured. Wherein different service processes on the service chain need to interact with each other, and establishing a connection relationship of each virtual machine according to an execution sequence of each service process so as to complete the message service of the service chain by utilizing each virtual machine. According to the technical scheme, extra external hardware equipment does not need to be added, and the influence of the forwarding performance of the OVS virtual switch is effectively solved by utilizing the physical forwarding performance of the high-performance network card.

Description

technical field [0001] The present invention relates to the technical field of service processing, in particular to a method, device and computer-readable storage medium for deploying an SFC service chain. Background technique [0002] The deployment of traditional service nodes is usually based on the physical topology, through manual configuration of various strategies, the above-mentioned service devices are connected in series to the service traffic path. When the service chain of a traditional network is changed or expanded, it is necessary to change the network topology and reconfigure the network equipment. This mode of deployment and operation and maintenance has many problems. The coupling between network devices is large, resulting in inflexible service deployment, low packet forwarding efficiency, and service devices cannot be shared. [0003] Service Function Chain (SFC) is a technology that provides orderly services to the application layer. SFC is used to log...

AI Technical Summary

Problems solved by technology

[0005] However, in conventional applications, the traffic classification nodes in SFC are generally undertaken by hardware access switches or OVS virtual switches, and hardware access switches need to use additional hardware devices to undertake, increasing deployment costs

However, the forwarding performance of the OVS virtual switch is limited, resulting in low business processing efficiency
