Real-time communication platform based on processor sub-core and virtual machine

Abstract

The invention relates to the technical field of networks, and discloses a real-time communication platform based on processor nucleus dividing and a virtual machine, for providing a real-time communication capability for a distributed system composed of a Windows operation system, a TCP / IP protocol and an Ethernet. The real-time communication platform comprises a subsystem running on a time correction master node and a subsystem running on a time correction slave node, wherein the former comprises a real-time communication protocol stack master station module, a time synchronization algorithm master station module and an RTX equipment driving module; and the later comprises a VMM module, a real-time protocol stack slave station module and a time synchronization algorithm slave station module which support a real-time virtual communication machine. According to the invention, real-time and determined transmission of data can be finished by use of the real-time communication platform; the data real-time validity among applications is guaranteed, and support is provided for real-time data interaction of the distributed system; and on the basis of real-time communication, a high-precision real-time clock function is provided, through a built-in time correction mechanism, system-level high precision time is provided, the clock consistency of each node in the distributed system is guaranteed, and a consistent time scale is provided for the distributed system.

Description

technical field [0001] The invention relates to a real-time communication platform and relates to the field of network technology. Background technique [0002] As we all know, now is the age of the Internet. A single computer cannot provide enough rich information. Only network interconnection and resource sharing can meet the growing demand of human beings for information. In the process of network interconnection, the quality and speed of communication has become a topic of concern. [0003] Not only the Internet, but the local LAN is also facing communication quality problems. For example, in a distributed network environment composed of multiple hosts, how to ensure the certainty of the communication quality between each host and how to ensure the real-time communication in the existing communication environment are all problems that need to be solved. [0004] Currently, PCs are still the terminal devices most connected to the network. As for the operating system r...

Problems solved by technology

[0005] In this way, in a large distributed network environment composed of multiple hosts, the communication between each host is not deterministic and real-time.

In most distributed environments, some key data transmitted between hosts must be guaranteed to be transmitted accurately within a certain period of time. Strong demand, but the current Windows communication environment cannot guarantee
