Information transmission method, information reception method, information transmission device and information reception device based on communication interface framework

Abstract

The invention discloses a communication interface framework, an information transmission and device method based on a communication interface framework, and an information reception method and device based on a communication interface framework and a communication system. The communication interface framework comprises a device layer, a core layer and a protocol layer; the device layer comprises a transmission layer; the transmission device is used for providing a transmission interface for transmitting data information to the framework in a process of transmitting data information; a core layer comprises an interface protocol, a transmission queue and a reception queue; the protocol layer comprises a user mode application program interface and an internal mode application program interface. The Information transmission method, the information reception method, the information transmission device and the information reception device based on the communication interface framework realize a unified communication mechanism. The communication mechanism is not limited to between user-mode common processes and can be also used between inner core assemblies, or between the inner core and the user process. Meanwhile, combining with a protocol interface, the information transmission method, the information reception method, the information transmission device and the information transmission device based on communication interface framework can cross a virtualized boundary, supports communication between virtual machines and can also support communication between the virtual machine and a host machine.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a communication interface framework, a method for sending messages based on the communication interface framework, a method for receiving messages based on the communication interface framework, and a communication system; A message sending device and electronic equipment of an interface framework, and a message receiving device and electronic equipment based on a communication interface framework. Background technique [0002] With the development of communication technology, when performing cloud computing or computer processing, it is often necessary to communicate between processes in the operating system, between virtual machines and virtual machines, and between virtual machines and host machines. mechanism to solve the problem. [0003] Under the existing technology, the commonly used communication mechanisms are as follows: [0004] 1. Inter-process com...

[0006] 3. NAT mode, using the NAT and DHCP services provided by VMware, the virtual machine uses the virtual network card Vmnet8 in the host as the gateway, this method can realize the communication between the host and the virtual machine, and the virtual machine can also access the Internet, but the Internet cannot access the virtual machine

[0007] 4. The host-only mode can only perform network communication between the virtual machine and the host, and the virtual machine cannot access the external network.

[0008] It can be seen that under the existing communication mechanism, the first communication mechanism is socket-based inter-process communication, which cannot cross the virtualization boundary (inside the same operating system); while other communication mechanisms, although they can cross virtualization However, it needs to be based on the semantics of network communication. Although it is based on the socket interface, it does not support message passing and filtering between kernel components. Various communication mechanisms operate independently of each other, and each communication mechanism is only responsible for its own situation. Communication, limited for deep extension
