Abstract: Embodiments of this application provide an image transmission method and apparatus. The method includes: converting a first high-resolution image into a first low-resolution image, where first resolution of the first high-resolution image is higher than second resolution of the first low-resolution image; encoding the first low-resolution image to obtain a first bitstream; obtaining a second high-resolution image, where third resolution of the second high-resolution image is higher than the second resolution, and the second high-resolution image includes high-frequency information of the first high-resolution image and excludes low-frequency information of the first high-resolution image; obtaining an image residual between the first high-resolution image and the second high-resolution image, where the image residual is used to reflect the low-frequency information of the first high-resolution image; encoding the image residual to obtain a second bitstream; and sending the first bitstream and the second bitstream.

Abstract: A remote procedure call (RPC) method for a network device and the network device, where a client sends an RPC request to an RPC core, where the RPC request requests to call a service deployed on a server, the RPC core receives the RPC request from the client and forwards the RPC request to the server when the RPC core determines that a dynamic service registry stores valid registration information of the server, the server receives the RPC request from the RPC core, and provides a corresponding service for the client according to the RPC request.
