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 application discloses a UDP message distribution method, a device and a readable storage medium. When there are a plurality of process groups for one application service at the same time, each process group has an independent ebpf resource, the ebpf resources being used for storing information of a file handle (fd) of each process in the process groups. After receiving a UDP message, a server determines a target process group from amongst a plurality of process groups of a reuseport group on the basis of a four-tuple of the UDP message, selects a target fd from amongst fds of processes of the target process group, and transmits and receives data by means of the target fd. In the used solution, since each process group has the independent ebpf resource, processes in different process groups will not preempt the same fd, thereby avoiding distribution of UDP messages being in disorder when the plurality of process groups coexist, which achieves the purpose of ensuring service quality. Moreover, the problem of soft interrupt performance consumption caused by UDP connect can be further avoided, providing a high-concurrency capability.
