The shelter hospital processing module comprises a source data acquisition module and shelter hospital aggregation gateway equipment; the shelter hospital aggregation gateway equipment and the remote receiving aggregation gateway equipment form a three-layer wide area network; the cloud platform is used for transmitting to-be-transmitted data of the shelter hospital to the remote receiving aggregation gateway device, the cloud platform comprises a plurality of service nodes, and the service nodes communicate through a plurality of heterogeneous physical links; during data transmission, the shelter hospital aggregation gateway device determines an optimal transmission link from the cloud platform, and the optimal transmission link is dynamically updated. The shelter hospital network can be quickly deployed, transmission data loss is reduced, and the service quality of the shelter hospital network is improved.

The application discloses a video data transmission method and device, equipment and a storage medium, and relates to the technical field of data transmission. A plurality of parameters, such as actual round-trip delay and packet loss detection duration, can directly reflect real-time network status. The compensation duration required for retransmitting a target video data packet if the target video data packet is lost under the current network status is accurately determined. Then, by comparing the size between the local cache duration fed back by a video receiving end and the packet loss compensation duration, it is determined whether the transmission strategy of retransmitting the target data packet for packet loss compensation will affect the video playing effect of the video receiving end. Then, a suitable target transmission strategy is selected from a transmission strategy set, the network service quality of a video transmission service is improved, and the video experience of a user is ensured.

The embodiment of the invention provides a port cache dynamic adjustment method and device and switching equipment, and relates to the technical field of digital communication. According to the method, multi-dimensional indexes such as used caches, current and historical cache utilization rates and time delays of multicast ports are collected in real time, and the comprehensive perception capability of the port running state is constructed. Redundant resources are dynamically released based on actual cache occupation conditions, and congestion risks are identified in advance in combination with load trend prediction, so that dynamic addition and allocation and cross-port on-demand allocation of cache resources are realized. According to the mechanism, resource stiffness caused by traditional static allocation is broken through, and the resource utilization efficiency and forwarding stability of the switching equipment in a video multicast scene are improved. Through dynamic capacity expansion, the capability of a port to deal with burst traffic is obviously enhanced, the packet loss probability caused by insufficient buffer areas is effectively reduced, the interruption or lagging of multicast video streams is reduced, the fluency and definition of video transmission are guaranteed, and the user experience and the network service quality are comprehensively improved.

A cell selection method, device, equipment and storage medium relate to the field of communication technology. The method includes: the terminal device determines the position relationship between the terminal device and the first network device according to the first information; when the position relationship meets the first condition, the terminal device selects the cell corresponding to the first network device as the resident cell. A method for selecting a resident cell based on the position relationship between the terminal device and the network device is provided. Since the difference in the position relationship between the terminal device and different network devices is relatively obvious, a more accurate reference can be provided for the terminal device to select a resident cell, so as to improve the accuracy of the resident cell selection result. In addition, since the resident cell is the cell selected by the terminal device when the cell is selected or reselected as the target cell, the access efficiency of the terminal device during subsequent random access and the switching efficiency during subsequent cell switching are also improved.

The application discloses a kind of intelligent DHCP relay system and method based on dynamic network topology perception, system includes: network detection module, configured to send probe packet to multiple DHCP servers, based on the response information of probe packet, obtain the network performance index of each DHCP server between forwarding path;Quality of service evaluation module is configured to receive the network performance index from network detection module, based on network performance index, the comprehensive score of each forwarding path is calculated, and the quality of service map is updated according to comprehensive score, wherein the quality of service map is used to store forwarding path and corresponding quality of service index;Routing decision module is configured to query the updated quality of service map in real time, based on comprehensive score, obtain optimal path, and encapsulate DHCP request message of DHCP client based on optimal path and forward to corresponding DHCP server.The embodiment of the application can reduce request delay through dynamic path selection, improve success rate.
