Abstract: This application provides a downstream packet sending method, a downstream packet forwarding method, a downstream packet sending apparatus, and a downstream packet forwarding apparatus. The downstream packet sending method in this application includes: configuring a downstream forwarding path of a downstream packet for a terminal device; generating a source MAC address based on the downstream forwarding path, where the source MAC address is used to indicate the downstream forwarding path; and sending the downstream packet to a forwarding switch, where the downstream packet includes the source MAC address. This application can reduce costs, improve efficiency, and simplify network traffic.

Abstract: Embodiments of the present invention provide a task scheduling method and apparatus on a heterogeneous multi-core reconfigurable computing platform. The method includes: when determining that a to-be-executed hardware task is in a ready state, adding the to-be-executed hardware task into a target hardware task queue corresponding to a function of the to-be-executed hardware task; reconfiguring, according to a priority of the to-be-executed hardware task and a usage status of multiple reconfigurable resource packages, at least one reconfigurable resource package in the multiple reconfigurable resource packages into a target intellectual property IP core that can execute the to-be-executed hardware task. According to the embodiments of the present invention, a more proper resource reconfiguration occasion can be determined, and a more appropriate reconfigurable resource package can be used for resource reconfiguration, thereby reducing reconfiguration overheads and improving utilization of reconfigurable resources in a task scheduling process.
