The present application provides a method, a means, a device and a storage medium for discovering a call link, which belong to the technical field of networks. The present application provides a solution for invoking a service link process without relying on a probe program to implement discovery of a call link. By generating a plurality of message sequences based on communication messages betweenmultiple services, the message sequence is generated according to multiple message sequences. Multiple classes to determine the calling link of services provided by multiple services, can restore thetopology between services in the application, without burying in the business code, avoiding the performance and stability of the probe program for business processing The impact of sex also avoids the security risks caused by the probe program. At the same time, the technology that gets rid of the probe burying point is limited by different technologies and different versions of the same technology, which greatly reduces development cost and maintenance cost.
