5results about How to "Solve congestion" patented technology

This invention discloses a data transmission method, apparatus, and system based on hierarchical port domains. The method includes dividing a switch port into several port switching units and switching domains. Each port switching unit includes several ports and first and second buffers. Each switching domain includes several port switching units and a temporary buffer. Each port has a pre-set internal routing number including a domain identifier, a unit selection bit, and a port index number. Data packets received by the receiving port are parsed to obtain the target port address and converted into a target internal routing number. If the unit selection bit of the target internal routing number is the same as that of the source internal routing number, the data packet is transmitted to the first buffer for reception by the target port. If the unit selection bits are different, the data packet is transmitted to the second buffer, and it is determined whether the domain identifiers are the same. If they are the same, the data packet is stored in the temporary buffer; if they are different, the data packet is placed in the out-of-band transmission queue for transmission to the target port. This invention offers high data transmission efficiency and good port scalability.

This disclosure provides a message transmission method, apparatus, electronic device, related medium, and program product. The message transmission method includes: generating a data packet; wherein a first field in the data packet has a first original port number; determining that a first original path from the sending device to the receiving device is congested based on a congestion window value corresponding to the current routing period of the sending device; selecting a first virtual port number corresponding to the current routing period from a first set of candidate port numbers, updating the first field with the first virtual port number, and placing the first original port number in a second field of the data packet; the first virtual port number is used for routing calculations to obtain a first alternative path from the sending device to the receiving device; and sending the data packet so that after receiving the data packet, the receiving device extracts the first original port number from the second field and updates the first field with the first original port number for transport layer protocol processing. This disclosure can effectively improve message transmission efficiency.

This invention relates to the field of real-time resource scheduling technology, specifically a real-time scheduling method for lane control robots based on multi-dimensional sensor data. The method includes: dividing management areas for arrival and drop-off robots; acquiring multimodal sensor data from the management areas, extracting features, and fusing them using a self-attention mechanism to obtain a fused feature vector; obtaining a drop-off scenario complexity score and a departure intention score through a drop-off scenario evaluation model; simultaneously calculating the real-time resource occupancy index for each lane; calculating differentiated allowed dwell time based on the drop-off scenario complexity score and the overall resource occupancy status of the drop-off platform; and providing early warnings and management based on the drop-off scenario complexity score, departure intention score, real-time resource occupancy index, differentiated allowed dwell time, and empty space detection results. This invention improves flexible decision-making capabilities and resource utilization, and is suitable for real-time resource allocation and decision support in complex traffic scenarios.

This application discloses a data transmission configuration device and method, specifically relating to the field of data transmission technology. The data transmission configuration device includes an on-chip network chip (Chip-on-Chip) and a digital multimedia extender (DME). The Chip-on-Chip is located in a mesh network and is used to transmit data to the DME via the mesh network. The DME is connected to the edge of the mesh network and is used to receive data via the mesh network. The Chip-on-Chip also counts the data transmissions. The count value in the Chip-on-Chip indicates the data transmission priority of the Chip-on-Chip. When the Chip-on-Chip sends a data transmission request to the DME, the count value decreases; when the Chip-on-Chip receives a signal returned by the DME, the count value increases. This solution enables data transmission configuration in a hardware device, resolving network congestion issues.
