Abstract:
A container isolation method for a netlink resource includes receiving, by a kernel executed by a processor, a trigger instruction from an application program. The method also includes creating, by the kernel according to the trigger instruction, a container corresponding to the application program, creating a netlink namespace for the container, and sending a notification to the application program indicating that the netlink namespace is created. The method further includes receiving, by the kernel, a netlink message from the container, wherein the netlink message comprises entries generated when the container runs. The method additionally includes storing, by the kernel, the entries based on an identifier of the netlink namespace for the container, to send an entry required by the container to user space of the container.
Abstract:
The present invention provides a wireless local area network WLAN and a method for communicating by using the WLAN, which includes at least one radio module and an access controller. The radio module converts a first air interface wireless signal from a station into a first baseband signal, and bears the first baseband signal on an Ethernet and sends the first baseband signal to the access controller. The access controller processes the first baseband signal to generate first service data, and forwards the first service data. The access controller further receives second service data, processes the second service data to generate a second baseband signal, and bears the second baseband signal on the Ethernet and sends the second baseband signal to the at least one radio module. The present invention can increase the efficiency and utilization rate of a spectrum.
Abstract:
An image upgrade method is provided. The method includes: receiving an incremental image file of a container, where the incremental image file includes a newly-added file, a modified file, and information about a deleted file, and the information about the deleted file includes a name of each deleted file and a storage path of the deleted file; updating an original image layer based on the incremental image file to obtain an updated image layer, where a state of the deleted file is set to a hidden state at the updated image layer; and overlaying a file at the updated image layer with a file at a container data layer to form an updated unified view at a view layer for use by the container, where the updated unified view does not include the deleted file whose state is set to the hidden state.
