This invention relates to a three-site mutual backup method under a commercial encrypted network virtualization architecture, belonging to the field of network communication technology. It addresses the technical problems of existing cross-regional and cross-network segment communication schemes, including insufficient interconnection security, adaptability, data backup efficiency, fault switching response speed, hardware architecture cost-effectiveness, and incomplete scenario coverage. The method includes the following steps: master station backup generation; parallel off-site replication; breakpoint resumption and anomaly recovery; local storage and version retention at branch stations; fault switching and local recovery. The three-site mutual backup method under the commercial encrypted network virtualization architecture of this invention offers: superior interconnection security and adaptability, more efficient and complete data backup, low-impact automated fault switching, a more reasonable and cost-controllable hardware architecture, higher detection accuracy, and stronger scalability.

Improved network traffic flow processing techniques are described. In a network device providing multiple processing planes, each processing plane comprising multiple processing units, techniques are described that take advantage of flow affinity / locality principles such that the same processing component of a processing plane, which previously performed processing for a network flow, is used for performing subsequent processing for the same network flow. This enables faster processing of network traffic flows by the network device. In certain implementations, the techniques described herein can be implemented in a network virtualization device (NVD) that is configured to perform network virtualization functions.

This invention provides a method and system for integrating distributed edge data center computing power based on DPU, relating to the processor field. The method involves: transmitting parameter replica management data and consistency control function data to the DPU layer corresponding to the DPU card deployed within the edge data center, obtaining the target DPU layer; constructing a hardware-layered communication topology combining intra-data center aggregation and cross-data center controlled transmission within the target DPU layer, obtaining the target DPU, which performs bandwidth awareness, QoS scheduling, cross-data center parameter coordination, and traffic shaping control; transmitting gradient processing and parameter synchronization control logic data corresponding to the edge data center to the target DPU, and performing hardware-level offloading and cross-data center intelligent scheduling through the target DPU; and controlling GPU resource virtualization and network virtualization through the target DPU, so that multiple edge data centers logically form a unified training resource pool, resulting in the distributed edge data center computing power integration.
