Abstract: This application provides a network acceleration method, an electronic device, and a readable storage medium, and relates to the field of network communication technologies. Different data flows in an electronic device correspond to different flow quality evaluation conditions. When a flow quality parameter of any data flow meets a flow quality evaluation condition corresponding to the data flow, the electronic device switches the data flow from a current network interface card to another network interface card for transmission, thereby implementing network acceleration. The flow quality parameter includes at least one of the following parameters: a latency, a rate, a packet loss rate, a retransmission rate, or whether a packet response times out. Because corresponding flow quality evaluation conditions are respectively set for different data flows, different network acceleration time points can be obtained for flow quality of the data flows, thereby avoiding a freezing phenomenon.

Abstract: Skew handling techniques are provided in parallel execution for even load balancing and scaling. In a compile-time solution, a dynamic sampling query is issued to detect partition skew. The compile-time solution determines the number of skewed partitions and uses a hybrid distribution scheme where skewed partitions use a random distribution and non-skewed partitions use the original server mapping. In a runtime solution, producer server processes create partition mapping vectors that contain partition mapping information. Each producer server process sends its partition mapping vector to the query coordinator (QC). The QC receives the partition mapping vectors from the producer server processes, merges the vectors, and determines a skew result based on the merged mapping vectors and sends the skew result to the producer server processes. The producer server process can alter distribution of skewed partitions based on the skew result.

Abstract: A network acceleration method, an electronic device, and a storage medium, which relate to the field of network communication technologies, so as to reduce freezing phenomena during video playback. The method includes: when an electronic device runs an application that does not include a peer-to-peer (P2P) flow, a data flow that requires high network quality may be switched to another network with better quality when quality of a currently used network is poor. When the electronic device runs an application that includes a P2P flow, and when a currently used network is poor, because it is difficult to switch the P2P flow to another network with better quality, all data flows of the electronic device may be switched to the another network, thereby reducing video freezing phenomena caused by a difficulty of switching the P2P flow to the another network with better quality.
