Abstract: 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.

Abstract: The present disclosure discloses a method and system for sharing a multi-protocol port and a server, where a designated field for storing a listening structure is newly added to a listening structure of an HTTP protocol. The method includes: writing, with respect to a target port, a listening structure of an RTMP protocol into the designated field of the HTTP protocol if the HTTP protocol and the RTMP protocol share the target port; detecting a target protocol corresponding to a connection request when the connection request is received by the target port; and reading the listening structure of the RTMP protocol from the designated field to obtain configuration information of the RTMP protocol if the target protocol is the RTMP protocol, and processing the connection request using the configuration information of the RTMP protocol.

Abstract: Embodiments of the present disclosure relates to the field of communication technology, which provide a method for real-time communication connection, a server, and a storage medium. The server is configured to have service processes in one-to-one correspondence with UDP ports. After receiving each respective SDP request sent by each of at least one client for resource negotiation from a TCP port of the server, the service processes send each respective SDP response to each of the at least one client based on the each respective SDP request. The each respective SDP response carries information of a UDP port corresponding to a service process that processes the each respective SDP request. The service process receives a UDP connection request sent by a client from the UDP port corresponding to the service process, and establishes a UDP connection by calling a Connect function to implement RTC connection.

The technical solution provided in the present disclosure can improve the quality of data transmission in networks.
