Abstract: Embodiments provides a low-latency data switching device and method. The device includes at least two boundary hardware modules and at least one optical forwarding module. The first boundary hardware module is configured for matching, with a first data forwarding table, signaling message information for a signaling message sent by a host router, acquiring a service request sent by the host router, and searching a second data forwarding table for an optical channel for the service request. The at least one optical forwarding module is configured for mapping the service request to a second service request, and forwarding the second service request in sequence via the optical channel, the second boundary hardware module is configured for acquiring next-hop routing information of the data switching device for the service request, and forwarding the service request to the next-hop router of the data switching device.

Abstract: A privacy-enhanced federated decision-making method, apparatus, system and a storage medium are provided for training a global decision-making model for ensuring data privacy of data terminals. Each federated data terminal reports information about a local decision-making model to a federated coordinator, and a federated coordinator trains a global decision-making model by using the information about the local decision-making model reported by the federated data terminals. The trained global decision-making model can be used for coordinating decision making of the federated data terminals, such as coordinating a decision-making sequence of the federated data terminals or coordinating whether the federated data terminals need to participate in a decision-making task. The method resolves the problem of difficult coordination across the data terminals, and improves the decision-making accuracy of the data terminals. The federated data terminals adaptively use the federated decision-making model for improving the decision-making flexibility of the federated data terminals.

Abstract: The invention discloses a cross-layer network fault recovery system and method based on configuration migration. The method includes: an upper layer switching network controller sends device fault information to a super controller; the super controller performs a fault device location, and selects a backup upper layer switching network device in an upper layer switching network; the super controller generates a third forwarding table, and delivers the third forwarding table to an upper layer switching network controller and an underlying layer switching network controller; the upper layer switching network controller generates a first forwarding table to be updated according to the third forwarding table, and delivers the first forwarding table to neighbor devices of the fault device and the backup upper layer switching network device; the underlying layer switching network controller calculates underlying layer switching network transmission channels according to the third forwarding table, and updates a second forwarding table of the underlying layer switching network devices on these transmission channels. The invention utilizes the reconfigurability of the underlying layer switching network to allow rapid replacement of the fault device and service recovery in the upper layer switching network.
