Abstract: A method and an electronic device for operator network switching are provided and relate to the field of terminal technologies. A currently activated profile in an electronic device is a first profile. Specifically, the method includes: accessing, by the electronic device, a first operator network based on the first profile; detecting a second operation after disconnecting a connection to the first operator network in response to a first operation; searching for a network based on stored profiles in response to the second operation, to obtain network search results corresponding to the stored profiles; activating a second profile based on the network search results corresponding to the stored profiles; and accessing a second operator network based on the second profile. In this way, operator network switching is implemented.

Abstract: A data forwarding chip and a server are disclosed. The server includes a data forwarding chip, a network interface card, and a processor. The data forwarding chip is separately connected to the network interface card and the processor through a bus. After receiving a data forwarding request sent by the processor or the network interface card, the data forwarding chip forwards, based on a destination address of the data forwarding request through an endpoint port that is on the forwarding chip and that is directly connected to a memory space corresponding to the destination address of the data forwarding request, to-be-forwarded data specified in the data forwarding request, such that when the server sends or receives data, cross-chip transmission of data between processors occurs, thereby reducing a data transmission delay.

Abstract: This application provides a method and an apparatus, for accelerating cold startup of an application. The method includes after identifying an event that instructs an operating system of a terminal to cold start up an application, obtaining, from a plurality of dimensions, current status information related to the cold startup of the application, where the current status information includes a hardware configuration of the terminal, current load of the operating system of the terminal, resource overheads for cold starting up the application, and duration corresponding to each of a plurality of tasks in a process of cold starting up the application. The method also includes determining, by analyzing the current status information, a plurality of objects that need to be optimized in the current process of cold starting up the application; and then obtaining, based on the determined objects.
