Abstract: The present application provides a model gradient update method and device, for use in improving the accuracy of model training. A central server repeatedly executes a gradient update process until a stop condition is satisfied. One gradient update process comprises: receiving first gradients respectively sent by multiple nodes, the first gradients being obtained by each node using sample data to train a model to be trained of the node one or more times; obtaining a second gradient one the basis of the multiple first gradients and the probability of each node in the present gradient update process, the probability of each node in the present gradient update process being determined by an Actor-Critic network one the basis of the probability of each node in the last gradient update process; and sending the second gradient to the multiple nodes, respectively.

Abstract: A method for communication between microservices, performed by a first host machine node, includes: obtaining a first microservice instance located on the first host machine node, determining a first microservice to which the first microservice instance belongs, and determining a list of triples corresponding to the first microservice according to the first microservice. The list of triples corresponding to the first microservice includes at least one triple, each triple of the at least one triple includes a visitor of the microservice, a visited party of the microservice, and an access port, and the visitor of the microservice of each triple included in the list of triples corresponding to the first microservice is the first microservice. The method also includes determining, by the first host machine node, an access policy of the first microservice instance according to the list of triples corresponding to the first microservice.

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: A method for sample alignment is applied to a first participant system, where a first trusted execution environment is deployed at the first participant system. The method includes, in the first trusted execution environment, obtaining at least one first sample identifier of the first participant system; through the first trusted execution environment, obtaining at least one second sample identifier of the second participant system from the second trusted execution environment, where the second trusted execution environment is deployed at the second participant system; in the first trusted execution environment, determining the first initial intersection of the at least one first sample identifier and the at least one second sample identifier and performing the shuffle processing on all first target sample identifiers in the first initial intersection to obtain the first target intersection; and based on the first target intersection, determining the first sample alignment result.
