Systems and methods are provided for establishing a network session with a device during which network session data is provided to the device via a network. The device may be connected to an LAN, and portions of data are configured to be selectively provided to the device via the network using a first queue for preferential network traffic or a second queue for non-preferential network traffic. During the network session, the systems and methods may identify characteristic(s) of a portion of the network session data, and determine, based on the characteristic(s), whether to provide the portion of the network session data to the device using the first queue or the second queue. Based on determining to provide the portion of the network session data using the first queue, the systems and method may provide the portion of the network session data to the device using the first queue.

A first device transmits a first random number to a second device through a first quantum channel, and receives a second random number from the second device through a second quantum channel. The first device generates a first encryption key based on the first random number and the second random number. The second device transmits the second random number to the first device through the second quantum channel, and receives the first random number from the first device through the first quantum channel. The second device generates a second encryption key based on the first random number and the second random number.

A data processing method, a network interface card, an electronic device, and a storage medium. The method includes: determining a target dispatch queue to be dispatched from a host memory in response to a doorbell signal sent by a target host, where the doorbell signal indicates that there is a target message to be sent; determining a current target dispatch state of the target dispatch queue, where the target dispatch state is obtained based on an activity and a credit value corresponding to the target work queue element; determining whether a dispatch mechanism corresponding to the target dispatch queue is valid based on the target dispatch state, where the dispatch mechanism indicates whether the target dispatch queue is allowed to be dispatched; and performing a dispatch operation on the target work queue element and the target message in response to the dispatch mechanism being valid.
