Example Embodiment

[0035] Example 1

[0036] Such as figure 1 As shown, this embodiment describes a data synchronization method of heterogeneous executive bodies, which is applied to a mimic switch. The mimic switch includes a heterogeneous executor, a mimic scheduler, and a switching chip. There are multiple heterogeneous executors. Each heterogeneous executor is connected to the mimic scheduler through a data communication interface. The mimic scheduler also passes 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 completing the synchronization of the STP status and data of the heterogeneous executive bodies after cleaning and recovery. The data synchronization module has the ability to process STP protocol messages, and can collect normal working heterogeneous The configuration BPDU message of the executive body and the configuration BPDU message sent by the external switch co...

[0058] Example 2

[0059] This embodiment describes a data synchronization device of heterogeneous executive bodies, which is applied to a mimic switch. The data synchronization device uses a data synchronization method of 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 mimic judgment module makes a judgment on the data sent by the heterogeneous executors. After the judgment, the data of the heterogeneous executors in the normal state is sent to the switching chip, and the heterogeneous executors in the abnormal state are cleaned and restored. During the data synchronization process, the mimic The judgment module also judges the configuration BPDU message sent by the heterogeneous executive body in the normal stat...

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

[0064] The heterogeneous executors are processors based on different architectures (such as X86, ARM, RISC-V, MIPS, etc.), and the heterogeneous executors run the control plane software of the exchange protocol required by the mimic switch to realize the configuration of the switching chip And so on.

[0065] The mimic scheduler includes a data communication interface and a data synchronization device of a heterogeneous execution body 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 ...

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...
