Heterogeneous function equivalent synchronization device

Abstract

The invention discloses a heterogeneous function equivalent synchronization device, comprising multiple heterogeneous function equivalents for providing service for external service requests; a scheduler for scheduling the heterogeneous function equivalents; and a synchronizer arranged between the heterogeneous function equivalents and the scheduler. The synchronizer is used for obtaining output results of the heterogeneous function equivalents, synchronizing the output results of the heterogeneous function equivalents, generating a target processing result and sending the target processing result to the scheduler. The synchronizer synchronizes the output results and working states of the heterogeneous function equivalents, the problem that the scheduler cannot identify different outputs of the heterogeneous function equivalents is overcome, the differences of different heterogeneous function equivalents on output service response are shielded, network attackers are difficult to sniff or scan defects or vulnerabilities in the device, and the security of the device is improved.

Description

technical field [0001] The invention relates to the technical field of network space security protection, in particular to a synchronization device for heterogeneous functional equivalent bodies. Background technique [0002] Computers and the cyberspace environment composed of computers have brought great convenience to people's life, work and study. The cyberspace environment composed of computers includes network equipment terminals (such as mobile phones, computers), and network-related services running on terminals. Software (such as browsers, communication software), servers, and various devices that provide interconnection for the network (such as switches, routers), etc. [0003] Devices in the cyberspace domain can be composed of systems, subsystems, components, modules, components, or devices, and the structural states presented to the outside by these devices are called structural representations. For devices with given service functions in the existing cyberspac...

Problems solved by technology

[0004] However, under the premise of ensuring the equivalence of its core service functions, heterogeneous functional equivalents still have differences in terms of implementation features, output formats, and operating performance.

For example, different heterogeneous functional equivalents may be in different states. Some heterogeneous functional equivalents can serve external service requests in an idle state, while some heterogeneous functional equivalents may be in a busy working state and cannot Provide services for external service requests; or limited by the internal structure of heterogeneous functional equivalents, some heterogeneous functional equivalents respond quickly to external service requests, and some heterogeneous functional equivalents output The response speed of the service is slow; or when an exception occurs in the heterogeneous functional equivalent, the abnormal heterogeneous functional equivalent will also affect the output service response of the entire device, or the format of the output result of some heterogeneous functional equivalents cannot make the device recognize

[0005] In view of the above differences, it will not only affect the scheduler's judgment on the output results of heterogeneous functional equivalents, and then affect the output service response of these heterogeneous functional equivalents to external service requests, but also make the working status of heterogeneous functional equivalents Inconsistency, making it difficult for the entire installation to work in harmony
