The application relates to a network management method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: detecting whether the initial connection state of a to-be-probed connection link in an infinite bandwidth network is in a normal state; the to-be-probed connection link comprises a first connection end and a second connection end; if the initial connection state of the to-be-probed connection link is in the normal state, a fault detection instruction is sent from the first connection end of the to-be-probed connection link to the second connection end of the to-be-probed connection link; the fault detection instruction comprises management data reports corresponding to a subnet management interface in the infinite bandwidth network; the to-be-probed connection link is subjected to fault detection according to the fault detection instruction, a fault detection result is generated, and the infinite bandwidth network is subjected to network management based on the fault detection result. The method can improve the security of the IB network.

Embodiments of the present application provide a task resource allocation method and apparatus, an electronic device, and a storage medium. The method comprises: acquiring a topology structure corresponding to a device node of a task to be executed, and reconstructing a secondary resource tree in the topology structure, wherein the secondary resource tree comprises switching unit (SU) nodes and InfiniBand device child nodes under the SU nodes; in response to issuing of a task instance to which an InfiniBand device resource is to be allocated, determining idle InfiniBand device child nodes in the secondary resource tree as candidate child nodes for the task instance; determining, from among the candidate child nodes, a target child node for allocating the task instance to the same SU node; and allocating the task instance to the target child node, and executing the task instance on the target child node. In the present application, allocating instances of the same task to device nodes within the same SU reduces cross-SU communication, thereby decreasing the data exchange amount of a switch, and improving resource management efficiency and task execution efficiency.

The method can calculate, by the routing engine, a routing map, based upon a routing scheme, for the plurality of hosts and the plurality of switches, the routing map comprising a plurality of forwarding tables. The method can configure, each of the plurality of switches with a forwarding table of the plurality of forwarding tables calculated by the routing engine.

This invention relates to the field of artificial intelligence security technology, specifically disclosing an AI security flaw detection system based on deep analysis and adversarial testing. The system includes a data preprocessing module, a deep analysis module, an adversarial testing module, a result evaluation module, a report generation module, and a central control module. The data preprocessing module communicates with the deep analysis module via a high-speed data bus. The deep analysis module communicates bidirectionally with the adversarial testing module via dual gigabit Ethernet. The adversarial testing module is connected to the result evaluation module via an InfiniBand network. The result evaluation module communicates with the report generation module via an HTTPS secure connection. The central control module is connected to each module via a CANFD control bus and a TSN time-sensitive data bus. Therefore, this invention, through the collaborative approach of deep analysis and targeted adversarial testing, can improve the accuracy of detecting security flaws in AI models and reduce the false negative rate. It is applicable to fields such as finance and healthcare, providing strong assurance for the reliable operation of AI systems.

A containerized virtual network element message transmission method and system, the message is transmitted between a memory switch and a virtual network element, the method comprises: a sender stores a to-be-transmitted message in an idle shared memory unit in a pre-created shared memory unit pool, and obtains a corresponding shared memory number; the sender sends a protocol frame containing the shared memory number to a target receiver; the target receiver accesses corresponding message data from the shared memory unit pool according to the shared memory number, and performs corresponding operations on the message data according to control information in the protocol frame. The message transmission process does not need to copy the message content, does not depend on special hardware such as RDMA and special network cards such as InfiniBand, and can be directly deployed in an x86 server and a standard container environment, thereby improving the transmission efficiency, effectively improving the compatibility of the zero-copy message transmission technology with the existing containerized network simulation system, and reducing the communication cost.
