Disclosed are a data processing method, an electronic device, and a computer-readable storage medium. During uplink transmission, upon receiving a first QUIC message from a client device over a target UDP port, an NGINX server sends the first QUIC message to the QUIC protocol stack, such that the QUIC protocol stack processes the first QUIC message to derive application layer data, and sends a first data stream including a first application layer data packet to an upstream server. During downlink transmission, the NGINX server receives a second data stream from the upstream server, caches a second application layer data packet included in the second data stream into a second cache, and delivers the second application layer data packet to the QUIC protocol stack for processing when the QUIC protocol stack is writable to derive a second QUIC message and sends the second QUIC message to the client device.

Embodiments of the present disclosure relate to cybersecurity technology, and disclose a method for displaying browser pages, an electronic device and a storage medium. The method for displaying the browser pages is applied to a proxy server. The proxy server includes a remote browser. The method includes: acquiring first pixel data corresponding to change regions according to a page currently displayed by the remote browser and compressing the first pixel data to obtain second pixel data; sending the second pixel data to a client, such that the client displays a corresponding browser page according to the second pixel data; acquiring third pixel data corresponding to the change regions according to the page currently displayed by the remote browser, the third pixel data being configured to supplement pixels lost when compressing the first pixel data; and sending the third pixel data to the client, such that the client displays a corresponding browser page according to the third pixel data. The method is at least conducive to improving the browsing interaction experience of users.

Embodiments of the present disclosure provide a network data packet processing method, an electronic device, and a non-transitory computer-readable storage medium. The electronic device acquires a network data packet from a first process of an application, determines a first path or a second path as a target path according to a target network address of the network data packet, and determines an access permission for the target resource corresponding to the target network address. Therefore, the network data packet is processed according to the target path and the access permission. In the above technical solutions, the electronic device diverts traffic according to the target network address of the network data packet, and there is no need to modify an IP header of the network data packet.

Method for processing a resource description file includes: receiving an access request directed to a target page from a client terminal, and receiving the resource description file fed back by an origin server with respect to the access request after transmitting the access request to the origin server; identifying one or more resource links in the resource description file and determining whether the one or more resource links include one or more external links; if the one or more resource links include the one or more external links, rewriting an external link of the one or more resource links to an internal link and replacing the external link in the resource description file with a corresponding internal link formed by rewriting the external link; and feeding back a rewritten resource description file to the client terminal to acquire resource of the target page according to the rewritten resource description file.

In response to there being multiple process groups for one application service concurrently, each of the multiple process groups has an independent EBPF resource, and the EBPF resource is used to store information of an FD of each process in each of the multiple process groups. After a UDP message is received, a server is configured to determine a target process group from multiple process groups of a reuseport group according to a quadruple of the UDP message, select a target FD from the FD of each process of the target process group, and receive and transmit data by using the target FD. In this way, since each of the multiple process groups has an independent EBPF resource, the processes belong to different process groups do not preempt the same FD, which ensures that the UDP message is not distributed in disorder.

The present disclosure provides a method for requesting resources and a terminal. The terminal sends a first resource acquisition request for a target resource to each of first edge nodes, determines each of second edge nodes based on each first amount of the target resource returned by each of the first edge nodes, and sends a second resource acquisition request for the target resource to each of the second edge nodes.

The embodiments of the present disclosure relate to the technical field of content delivery network, and disclose a service processing method. The service processing method includes: receiving a customized service logic issued by a CDN user, receiving a user request corresponding to the customized service logic, loading the customized service logic and the user request to at least one execution process of a restricted namespace, where the restricted namespace is restricted to at least one of accessing CDN system files, calling key system interfaces, and using system resources, and processing and responding to the user request in the at least one execution process according to the customized service logic.

Embodiments of the present disclosure relate to the field of communication technology, and disclose a resource acquisition method, including: receiving a user input event from a first browser on a client; acquiring an event result triggered at a second browser by the user input event, where the second browser runs on the server for the WebVPN; acquiring, using the second browser, resources from a source station according to the event result; and feeding back the resources to the client, to present the resources at the first browser. Embodiments of the present disclosure further disclose a proxy server for a WebVPN, a resource acquisition system, and a server.

Embodiments of the present disclosure relate to communication technology. A method for DASH media streaming, an electronic device and a storage medium are provided. A first MPD file, a media initialization file, and a first media slice file of a DASH media stream to be played are acquired from a server by sending at most two acquisition requests to the server. The media initialization file and the first media slice file are acquired through one of the at most two acquisition requests. Subsequent MPD files are requested from the server according to the first MPD file, and other media slice files in addition to the first media slice file are acquired from the server according to the subsequent MPD files.
