Problems solved by technology

[0007] Aiming at the existing technology in the mimetic switch, heterogeneous executives perform data synchronization through the mimetic scheduler, a large amount of storage space is wasted during synchronization, and manual matching of STP protocol stack codes on heterogeneous executives is very complicated and cumbersome. The present invention provides A data synchronization method, device and mimetic switch based on the STP protocol. By adding an STP data synchronization module, the STP protocol stack code of the heterogeneous executable is not manually modified, and the cleaning and recovery are completed without occupying additional storage resources. Data synchronization between post-heterogeneous executives and other heterogeneous executives

Embodiment 1

[0036] Such as figure 1 As shown, this embodiment describes a data synchronization method for heterogeneous executives, which is applied to a mimetic switch. The mimic switch includes a heterogeneous executive body, a mimic scheduler, and a switching chip. There are multiple heterogeneous executive bodies, and each heterogeneous executive body is connected to the mimic scheduler through a data communication interface, and the mimic scheduler also passes through The data communication interface is connected to the switching chip.

[0037] The data synchronization module is set in the mimic scheduler. This module is responsible for synchronizing the STP state and data of the heterogeneous executives after cleaning and recovery. The data synchronization module has the ability to process STP protocol messages. It can collect the normal working heterogeneous The configuration BPDU message of the executive body and the configuration BPDU message sent by the external switch are used f...

Embodiment 2

[0059] This embodiment describes a data synchronization device for heterogeneous executives, which is applied to a mimetic switch. The data synchronization device uses the data synchronization method for heterogeneous execution bodies as described in Embodiment 1 to perform data synchronization. The data synchronization device includes a mimic judgment module and a data synchronization module, and the mimic judgment module is connected with the data synchronization module and communicates with each other.

[0060] The mimicry judgment module judges the data sent by the heterogeneous executive body. After the judgment, the data of the heterogeneous executive body in the normal state is sent to the switch chip, and the heterogeneous executive body in the abnormal state is cleaned and restored. During the data synchronization process, the mimic The judging module also sends the configuration BPDU message sent by the heterogeneous executive in normal state to the data synchronizat...

Embodiment 3

[0063] This embodiment describes a mimetic switch, including several heterogeneous executive bodies, a mimetic scheduler, and a switching chip. Each heterogeneous executive is connected to the mimic scheduler through a data communication interface, and the mimic scheduler is also connected to the switch chip through the data communication interface.

[0064] The heterogeneous executive body is a processor based on different architectures (such as: X86, ARM, RISC-V, MIPS, etc.), and the heterogeneous executive body runs the control plane software of the switching protocol required by the mimic switch to realize the configuration of the switching chip and so on.

[0065] The mimetic scheduler includes a data communication interface and a data synchronization device for heterogeneous executives as described in Embodiment 2. The data synchronization module in the data synchronization device is connected to the switching chip through the data communication interface, and the data ...

Abstract

The invention discloses a data synchronization method and device based on an STP protocol and a mimicry switch, and belongs to the technical field of network security protection. The invention discloses a mimicry switch. The heterogeneous executor performs data synchronization through the mimicry scheduler; lots of memories are wasted to store network topology data; an STP protocol stack code on the heterogeneous execution body is manually matched; complex operation, the invention provides a data synchronization method based on an STP protocol on a mimicry switch. After the heterogeneous executor in the mimicry switch is cleaned and recovered, collection and self-training of topological information of each port of the STP are completed through the data synchronization module, then the topological information is synchronized to the cleaned and recovered heterogeneous executor to be synchronized, data synchronization of the heterogeneous executor to be synchronized is completed, and normal use of the heterogeneous executor is recovered. According to the data synchronization method, the STP stack code of the heterogeneous execution body does not need to be modified manually, extra storage resources are not occupied, the synchronization speed is high, the efficiency is high, and the stability is better.

Description

technical field [0001] The invention relates to the technical field of network security protection, and more specifically relates to a data synchronization method, device and mimic switch based on the STP protocol. Background technique [0002] With the continuous development of network technology, people's way of life has undergone tremendous changes, and network security has increasingly become an important research issue in the current society. The mimetic defense mechanism effectively responds to or defends against known risks or uncertain threats based on vulnerabilities, backdoors, etc. through the dynamic defense plus redundant structure as the core mechanism. [0003] Mimic switch is a typical application of mimic defense technology. Usually, multiple heterogeneous processors are used as heterogeneous executives, and the system includes a hardware-implemented mimetic scheduler to realize the decision screening of downlink data and the distribution of uplink data for...
