Abstract: The present disclosure provides a region interconnect (RI) controller including a region interconnect routing module configured when a tenant is created. The region interconnect routing module is configured to assign a first identifier to the tenant for identifying traffic of the tenant, in a core switching network, create a virtual routing forwarding instance for the tenant and bind the first identifier and the virtual routing forwarding instance, and to activate a dynamic routing protocol in the core switching network and bind a dynamic routing protocol instance to the virtual routing forwarding instance, where virtual routers corresponding to the tenant and distributed in a plurality of independent network partitions are associated with the region interconnect control method and a computer storage medium. The technical solution of the present disclosure achieves a direct intranet connection in a heterogeneous SDN network region.

Abstract: Provided are a federated graph clustering method based on distributed graph embedding, a device, and a readable storage medium. The method comprises: constructing a first graph on the basis of first party data, and constructing a second graph on the basis of second party data; performing an encrypted intersection on the first party data and the second party data, determining common nodes in the first graph and the second graph, and associating the first graph with the second graph according to the common nodes to obtain a federated graph; learning on the federated graph by using a random walk-based distributed graph embedding algorithm, and determining a first graph embedding vector [PiA, PiB] starting from the first graph and a second graph embedding vector [PiA′, PiB′] starting from the second graph; and performing a clustering analysis on the first graph embedding vector [PiA, PiB] and the second graph embedding vector [PiA′, PiB′] of the federated graph on the basis of a federated clustering method to obtain a clustering result. By utilizing the present method, federated graph clustering can be carried out on private data of two parties, and a better clustering effect is obtained.
