Embodiment Construction

[0028] The specific implementation manner of the present invention will be described in detail below in combination with Linux applications. It should be pointed out that the present invention is not limited to any specific hardware platform and operating system, and can be easily applied to other environments and has wider versatility.

[0029] Process migration refers to the act of transferring a process between a source node and a target node when the process is running. Since the active (Active) process is transferred in this process, it is also called preemptive (Preemptive) process migration. In general, a process must be stopped before being migrated so that the state of the process can be fetched and transferred to the target node. On the target node, the execution information of the migration process is reconstructed and execution continues.

Abstract

The present invention discloses a transparent process migration device and method. The present invention which makes full use of the characteristics that the operating system has a user space and a kernel space adopts double layer software function to migrate transparent processes, improving the migration efficiency and reducing the system cost. In addition, the present invention also solves the problems such as the overdependence of present algorithm on internet protocols and a poor portability. Thus the present invention is characterized by directness, high efficiency as well as wide applications.

Description

technical field [0001] The invention relates to a network operating system process migration technology in the computer field, in particular to an efficient process migration device and method with network connection transparency. Background technique [0002] From cluster computing to Internet computing to today's grid computing, current computing technologies have focused more on collaboration, data sharing, cycle stealing, and other interaction patterns in dynamic and geographically distributed organizations. Under this trend, process migration technology has become an increasingly indispensable mechanism in modern communication and computing systems because it can achieve system fault tolerance and dynamic maintenance; support load balancing and sharing; optimize local resource utilization. [0003] Process migration refers to the act of transferring a process between a source node and a target node when the process is running. The main work of process migration can be ...
