ASYNCHRONOUS I/O MODEL FOR HIGH-PERFORMANCE NETWORK SERVER

摘要

The invention asynchronously input processing method for high-performance network server, how to handle the asynchronous input and output the method, a) comprising a thread (thr) of the asynchronous input and output thread group (aio_thread_group) generates an asynchronous IO (AIO-request) in order to obtain the necessary data from the device and presented to the kernel; b) When AIO-request received through the system call, the kernel can process it, registering in the kernel structures; c) a device command and the kernel configuration, sending the command to the device; d) The kernel before step c) of the command response comes spent in step to run other processes; And e) step c) the response (data) hayeoteul arrives on the command sent in the step, the steps performed by the kernel to the req a parameter for executing a callback to the user within the space, a streaming service, a web service, a network game The IO model for building a high-performance network servers that need to support high-performance services in areas such as input and output.
