METHOD FOR LARGE CAPACITY DATA TRANSMISSION USING KERNEL LEVEL FUNCTION

摘要

the present invention is a kernel-level functions with large data transfer method according to the Web service (Web Service) to In the large-capacity data transmission method using a kernel level of the Web server (Web Server) system (Kernel Level) function to provide, if there is data transmission request from a connected client program (Client Program), the Web server system, a certain user level (User Level) and the process that calls the function, and then the Web server, the system will call a particular user-level functions, the specific function is a user-level process that verifies whether the access by the client program the size of the requested data is a predetermined size or more and, when the size of the data having a predetermined size or more, the Web service function and the process of calling a particular kernel-level functions, the particular kernel-level function and the process of copying the kernel buffer to load the large amounts of data, the kernel After copying the data to the buffer capacity, the specific function is a user-level kernel domain when transferring large amounts of data to the client program to include the process of transmitting the large amount of data copied to the access by the client program via the network interface is due to the large amount of data in the kernel space without the exchange of the kernel area to be transferred directly to the client program, the benefits and increase efficiency by reducing the overhead on the Web server machine.
