Construction method of network call relation topological graph

The invention provides a method for constructing a network calling relation topological graph, which comprises the following steps of: S1, collecting calling relation data, namely collecting the calling relation data of network applications by using a package capturing tool or a log analysis method, including calling relations and calling time among services; s2, a calling relation graph is constructed, a directed graph is constructed according to the collected calling relation data, the service represents nodes, the calling relation represents edges, and the weight represents the calling frequency or delay. The invention provides a construction method of a network calling relation topological graph, and solves the problems that when network application has a complex distributed architecture, all network calling relations cannot be accurately captured in the prior art, and calling relation analysis of large-scale network application often has limitation on calculation and storage, so that the network calling
