Embodiment Construction

[0043] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the inventive concept. These all belong to the protection scope of the present invention.

[0044] The small size of the kernel is a significant feature of the microkernel. Only the necessary functions are implemented in the microkernel and the necessary abstractions are provided. Implementing resource isolation mechanism based on microkernel operating system can solve the problem of too large trusted computing base in traditional container technology. Container technology is based on the macro-kernel operating system Linux. The current number of lines of code in the Linux kernel has reached the order...

Abstract

The invention provides a microkernel operating system resource isolation method and system. The method comprises the steps that CPU resources and memory resources of all processes are managed through abstraction of a resource container; an equipment bandwidth isolation mechanism is realized in the related user state server; and realizing a process sandbox mechanism based on the capability mechanism. Compared with the prior art, the invention provides a new microkernel operating system resource isolation mechanism aiming at the resource isolation problem in the cloud computing scene, and the mechanism ensures the lightweight performance, also realizes stronger resource isolation than the current container technology, and well meets the frontier requirements of the current industry.

Description

technical field [0001] The invention relates to the technical field of microkernel operating systems, in particular, to a method and system for isolating resources of a microkernel operating system, in particular to a method and system for isolating resources of a lightweight microkernel operating system. Background technique [0002] Achieving a good resource isolation mechanism is a basic requirement of the cloud computing environment. Physical resources on a typical computer include a central processing unit (Central Processing Unit, CPU), memory, network, and external storage devices. In traditional non-cloud computing usage scenarios, users deploy their computing tasks to physical machines purchased by themselves, and users enjoy these physical machines exclusively. At this time, there is no problem of resource isolation. In the cloud computing scenario, users' computing tasks are deployed on virtual machines provided by cloud service providers, and the computing tasks...
