Service chain generation method and device, electronic equipment and storage medium

Abstract

The invention discloses a service chain generation method, device, electronic equipment and a storage medium. The method comprises the steps of obtaining a logic flow table issued by an SDN controller, wherein the logic flow table is a service chain logic flow table generated according to a logic port reported by the switch and a preset service node; obtaining a port state of a physical port of a switch connected with the preset service node and a link state between the current switch and other switches in the logic flow table by using a pre-deployed MLAG application; determining an actual physical port corresponding to the logic port in the logic flow table according to the port state; and generating a target service chain according to the determined physical port and the obtained link state. Therefore, the physical port state and the link state do not need to be perceived by an upper layer SDN controller, the arrangement and generation process of the service chain does not need to be participated by the upper layer controller, the arrangement and generation process can be automatically realized at a bottom layer, the timeliness of service chain generation is effectively guaranteed, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a method and device for generating a service chain, an electronic device, and a computer-readable storage medium. Background technique [0002] When data packets are transmitted in the traditional network, they need to pass through various service nodes, so as to ensure that the network can provide users with safe, fast and stable network services according to the design requirements. Service Chain (Service Chain), that is, the form of network traffic passing through these business nodes (mainly referring to security devices such as firewalls, load balancing, third-party security devices, etc.) in the established order required by business logic, can be understood as a business form. [0003] 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. Service c...

Problems solved by technology

[0005] However, during the research process, the applicant found that both of the above two methods require the upper layer of the control layer to sense, re-arrange the service chain and issue the flow table, which will lead to very low timeliness when the service node involves a lot of service chains
