Abstract: This application provides techniques comprising creating a main thread and at least two task threads; determining, by the main thread, a target task thread based on a data packet corresponding to a data transmission task in response to detecting the data transmission task associated with a client device, and sending the data packet to the target task thread, where the target task thread is any one of the at least two task threads; and receiving, by the target task thread, the data packet sent by the main thread, determining, based on the data packet, a first file descriptor corresponding to the client device, and communicating with the client device by using the first file descriptor to perform data transmission.

Abstract: This application provides techniques for establishing a P2P connection. The techniques comprise communicating with at least two auxiliary nodes to obtain answer messages returned by the at least two auxiliary nodes; determining, based on the answer messages, at least one public network address corresponding to an internal network address of a first client device; registering, with a cloud server, the at least one public network address corresponding to the internal network address of the first client device, and monitoring the at least one public network address corresponding to the internal network address of the first client device; and establishing a P2P connection to a second client device when detecting, in a preset duration, that the second client device returns a response data packet to a target public network address.

Abstract: This application provides techniques comprising S1: establishing a queue for accommodating m file descriptors for creating n1 first access request data packets; S2: creating an ith file descriptor in the queue, sending an ith first access request data packet by using the ith file descriptor, and monitoring a source port recorded by the ith file descriptor; S3: at every first preset time interval t1, enabling i to automatically increase by 1, continuing to perform operation S2, and setting preset monitoring time T for each source port, where T=t1*m; and S4: ending monitoring of an (i?m)th source port and destroying a corresponding file descriptor while creating an ith file descriptor in the queue when m*j<i?m*(j+1), and stopping monitoring of other source ports in response to detecting that a first port receives a response data packet, where the first port is any source port in a monitored state.

Abstract: The present invention provides a method, device and computer-readable medium of a seamless and dynamic switch between resolutions based on hardware decoding and belongs to a field of the internet technology. According to the method, device and computer-readable medium of the present invention, during a DASH video playback, when it needs to switch to another resolution, the original decoder continues to decode the video stream in the original encoded format that already stores in a buffer, while the video stream in the original encoded format is decoded, a second decoder corresponding to a target encoded format is initialized based on a video stream in the target encoded format received by the original decoder, and the video stream of the target encoded format is decoded by the second decoder, so as to realize the seamless switch between resolutions, avoid a jam in the process of playing the video, and improve the user experience.
