A method, device and medium for deploying SFC service chain

Abstract

The embodiment of the present invention discloses a method, device and medium for deploying an SFC service chain. According to the number of service processes carried in a virtualization instruction, a corresponding number of virtual machines are constructed on a network card. According to the function attribute corresponding to the target service process, a corresponding number of virtual interfaces are configured for the target virtual machine. The target virtual machine is any virtual machine among all virtual machines; the target service process is the service process corresponding to the target virtual machine. According to the processing method of the target virtual machine, the interface configuration of all virtual machines can be completed to ensure the service process of each service process. Executed smoothly. Different business processes on the business chain need to interact. According to the execution sequence of each business process, the connection relationship of each virtual machine is established, so that each virtual machine can be used to complete the message service of the business chain. The technical solution does not need to add additional external hardware devices, and utilizes the physical forwarding performance of the high-performance network card to effectively solve the impact of the forwarding performance of the OVS virtual switch.

Description

technical field [0001] The present invention relates to the technical field of service processing, and in particular, to a method, an apparatus and a 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. By manually configuring various policies, the above-mentioned service devices are connected in series to the service traffic path. When the service chain of the traditional network is changed or expanded, the network topology needs to be changed and the network equipment needs to be reconfigured. There are many problems in this mode of deployment and operation and maintenance. The coupling between network devices is large, resulting in inflexible service deployment, low packet forwarding efficiency, and inability to share service devices. [0003] Service Function Chain (SFC) is a technology that provides ordered services to the application lay...

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
