Device for operating protocol stack and method

Abstract

The invention discloses a device for operating a protocol stack and a method. The device comprises a protocol stack user process and a socket layer protocol agent module, wherein the protocol stack user process is used for operating the protocol stack in a user space independently of an application program process; and the socket layer protocol agent module is registered in a kernel space when a system is initialized and is used for communication between the application program process and protocol stack user process. The method comprises the following steps that: the protocol stack user process which is independent from the application program process operates in the user space, and when the system is initialized, the socket layer protocol agent module is registered in the kernel space; and the application program process is communicated with the protocol stack user process through the socket layer protocol agent module. Due to the utilization of the device and the method, the reliability, the information sharing degree and the compatibility of the protocol stack can be improved and the debugging, maintenance and development difficulty of software platform transplantation is reduced.

Description

technical field [0001] The present invention relates to computer information processing and communication technologies, in particular to a computer network protocol stack operating device and method. Background technique [0002] In the field of computer information processing and communication, because the embedded operating systems are not unified, for example, the commonly used embedded operating systems are VxWorks, Unix, Linux, etc., so the software platform sometimes needs to be transplanted across operating systems. The transplant process often requires special handling. For example, when the software platform is transplanted from other operating systems to the Linux operating system, the related protocol stack services need to be transplanted to the Linux network protocol stack. [0003] The Linux operating system itself is divided into two parts, one part is the core software, also known as the kernel space, and the other part is the ordinary application program, w...

AI Technical Summary

Problems solved by technology

[0005] First of all, each application process has a protocol stack, but they cannot access each other, resulting in information such as routing information, socket (socket) information, and TCP connections cannot be shared

[0006] Secondly, the read, write, and select operations similar to system calls cannot interact with these protocol stacks, which means that these protocol stacks do not support these standard functions, and the compatibility is not high.
