Abstract

The invention discloses a data sending and receiving method and device and a data processing system. The method is applied to a network card driving program, the network card driving program is located in a user mode space of an operation system, and the method comprises the steps of reading the target data written by a network card from a network card shared memory, wherein the network card shared memory is a memory buffer area of the network card shared by the driving program and the network card; determining the decapsulation information of the target data, wherein the decapsulation information comprises a target port number; according to the decapsulation information, decapsulating the target data, wherein the decapsulation process comprises a verification process, and the verificationprocess comprises the steps of verifying whether the target port number is a registered port number or not; and when the verification is passed, sending the de-encapsulated target data to a target service process. According to the embodiment, the data transmission can be carried out by bypassing the kernel mode space of the operating system, so that the utilization rate of the CPU is reduced.

Description

technical field [0001] The present application relates to the field of data processing, and in particular to a data sending and receiving method, device and data processing system. Background technique [0002] With the development of network technology, webcasting is becoming more and more popular, and all kinds of social activities can be spread by means of webcasting. [0003] In a live broadcast distribution network, in order to reduce transmission delay, UDP (User Datagram Protocol, User Datagram Protocol) transmission mode is generally adopted. As the business grows, the throughput of UDP traffic on the server will be very high at peak times, which will occupy more CPU resources when the server processes UDP packets and affect CPU performance. Contents of the invention [0004] In view of this, the present application provides a data sending and receiving method, device and data processing system. [0005] According to the first aspect of the embodiments of the pre...
