3results about How to "Reduce bandwidth costs" patented technology

This invention relates to the field of port data processing, and more particularly to a green port energy digital management platform based on digital twins. When constructing the digital twin, this invention utilizes an incremental synchronization mechanism and spatiotemporal event identifiers to ensure that the green port energy digital management platform only transmits incremental data that has changed. This not only saves on expensive cloud resources and dedicated line bandwidth costs, but also allows the green port energy digital management platform to maintain smooth operation even when dealing with massive amounts of data. Furthermore, through the incremental synchronization mechanism, this invention ensures that the green port energy digital management platform only updates the digital twin when changes occur, and combined with an efficient event bus, latency is drastically reduced from minutes to seconds.

Embodiments of the present application disclose a log management method and device, a storage medium and an electronic device. The method comprises: extracting a first instruction address in a call stack, the first instruction address being an address corresponding to a first instruction of a preset operation in the call stack; analyzing the first instruction address to obtain a target original address, the target original address pointing to an original instruction address of the first instruction in a symbol image; extracting second instruction addresses in turn; for each second instruction address, determining a first feature value and a second feature value, the first feature value being a distance difference value of an original instruction address of a corresponding instruction in the symbol image relative to the target original address, and the second feature value being an instruction quantity difference value of the corresponding instruction relative to the first instruction; and generating a log according to the target original address, the first feature value and the second feature value corresponding to each second instruction address. The present application can reduce the amount of log data.

This application discloses a video file distribution method and apparatus. The method involves: acquiring change messages for various media assets on a video platform; updating the media asset copyright information of each media asset based on the change messages; traversing video files that have passed the video platform's review; determining the target copyright playback region information of the video file based on the target media asset copyright information matching the video file; and triggering the video file to be pre-warmed to the CDN node of the corresponding target copyright playback region according to the target copyright playback region information. This method distributes video files to CDN nodes in the target copyright playback region, thereby ensuring that only videos allowed to be played in overseas countries and regions are distributed to the corresponding overseas country / region origin server. This minimizes the bandwidth costs incurred in distributing video files overseas and the storage costs of files on overseas origin servers while guaranteeing the user's viewing experience.
