Abstract: In an example method, a first device establishes a connection for multi-screen collaboration to a second device. The first device turns off a screen in response to a first event. The first device draws screen content based on a first software signal in response to a second event, to obtain a screen content drawing result. Then, the first device synthesizes the screen content drawing result based on a second software signal, to obtain a screen content synthesis result. The first software signal and the second software signal are software synchronization signals that are generated by a same software signal source in the first device and that have a same cycle. Finally, the first device sends the screen content synthesis result to the second device.

Abstract: The present invention discloses a packet forwarding method and a network access device, where a forwarding module is added between WIFI controllers and USB controllers in an original architecture forwarding process. This module is implemented by hardware, has a forwarding entry, parses a packet according to a standard TCP/IP protocol, and then performs operations or actions such as editing, copying, discarding, and forwarding on the packet. Content of the forwarding entry is learnt by a Linux network protocol stack from an initial packet sent by the WIFI controller or the USB controller, and then a related rule is configured in the forwarding module; then, a subsequent packet from the WIFI controller or the USB controller is directly forwarded by the forwarding module. This packet forwarding method improves forwarding performance compared with the prior art.
