The present invention relates to a location-awareness-based network intermediate device, at least comprising a scheduling module, which is configured to fuse short-term historical data about short-term and/or real-time network performance and location-awareness-based multi-day network performance data, so as to generate context data for predicting network performance, and acquire a deterministic connectivity mode in a mobile network environment based on the context data so as to enhance performance of end-to-end transmission. With this configuration, the concept of location-awareness-based packet scheduling can be translated into an actual system for end-to-end multi-path transmission. From the location-awareness-based long-term multi-day network performance data, the deterministic connectivity pattern of trains in the high-speed mobile network environment can be acquired, and after being fused with the short-term historical data observed in a short time period, a good basis for calibration of prediction of network performance can be provided, thereby enhancing robustness of network connectivity in a high-speed movement scene.

Location-awareness-based network intermediate device

The present invention relates to a relay device based on multi-path scheduling, at least comprising: at least one communication-receiving module, at least one hardware interface module, and at least one data-processing module, wherein the data-processing module, according to a specific type of target data, distributes the user data received through the communication-receiving module to a first processing path that processes the data in a predetermined manner and a second processing path that is independent of the first processing path and bypasses a kernel protocol stack. The data-processing module employs a multi-stage continuous scheduling manner to drive the user data in the second processing path to be transmitted in at least two mutually independent communication paths, thereby realizing multi-path transmission between the plural clients and the plural servers. This configuration not only lifts the logic of packet scheduling to the application layer, but also ensures path quality, QoE, and fairness while maintaining the multi-connection, multi-path, application-independent nature.
