Embodiment 1

[0020] figure 1 It shows the implementation flowchart of the network communication method provided by the embodiment of the present invention, which is described in detail as follows:

[0021] In step S101, create a network data sending and receiving thread and a listening interface in the system kernel, associate the network data sending and receiving thread with the listening interface, and add the listening interface to the epoll queue.

[0022] In the embodiment of the present invention, a network data sending and receiving thread is created in the system kernel, and the thread is used for the system to receive various types of data sent by the client through the network, and return the processed data to the client. And create a listening interface in the kernel of the system, bind the listening interface with the network data sending and receiving thread, and add the listening interface to the epoll queue, so that the listening interface circulates in the epoll queue run...

Embodiment 2

[0037] Such as Figure 5 Shown is a structural diagram of the network communication system provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0038] The listening interface module 21 is used to associate with the network data sending and receiving thread module and join the epoll queue, listen to events in the system epoll queue, process different events that need to send and receive data, and notify the network data sending and receiving thread module to send and receive data .

[0039] The network data sending and receiving thread module 22 is configured to associate with the listening interface module 21 and send and receive network data according to the notification of the listening interface module 21 .

[0040] Wherein the listening interface 21 specifically includes:

[0041] The association module 211 is configured to associate with the netw...

Abstract

The invention belongs to the network communication field and provides a network communication method and a system. The method comprises the following steps that: a network data transceiving thread and an interception interface are associated, and the interception interface is added to an epoll array; the interception interface intercepts events in the epoll array, and when the interception interface intercepts an event needing transceiving data, different events are processed and the network data transceiving threads associated with the different events are notified to transmit and receive data; and the network data transceiving thread transmits and receives network data according to notification of the interception interface. In the embodiment of the invention, the interception interface is established in the system kernel to intercept the events in the epoll array, to notify the network data transceiving thread to export a socket-associated function symbol table, and to transmit and receive the data by using a standard system call corresponding to the function symbol table in the kernel, so that the transceiving of the data in the kernel process is realized.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a method and system for sending and receiving network data. Background technique [0002] In the architecture of the network system, sending and receiving data is a very important issue. The timeliness of sending and receiving data directly affects the quality of the network. The existing technology sends and receives data directly in the user state to directly call the system process to send and receive data. Although this method is convenient and direct, it needs to call a system process every time data is received or sent, which causes excessive pressure on the system and low performance of network data transmission and reception. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a network communication method, aiming at solving the problem of low performance of network data transmission and reception when the existi...
