Problems solved by technology

For the case of bypassing the input proxy module and directly attacking the executive body, after the N-1-mode attack or N-mode attack occurs, because the arbiter cannot identify the N-1-mode attack or N-mode attack, the wrong ruling result is regarded as the correct one. The result of the verdict is output to the command system, thereby affecting the hardware configuration process of the switch

Embodiment 1

[0031] Such as figure 2 As shown, a fast identification method for online executive faults includes the following steps:

[0032] While distributing the input streams to multiple online executives, the input proxy module uploads the input streams or the hash values ​​of the input streams to the feedback controller, and the feedback controller stores the input streams or the hash values ​​of the input streams in the order received to the input agent message queue;

[0033] After receiving the input stream, each online executive uploads the input stream or the hash value of the input stream to the feedback controller, and the feedback controller stores the input stream or the hash value of the input stream in the corresponding online execution in the order of receipt body message queue;

[0034] When the scheduler schedules a new executor to go online, the feedback controller compares the input agent message queue with the input stream or the hash value of the input stream in...

Embodiment 2

[0038] Such as image 3 As shown, this embodiment provides a rapid recovery method for a mimic switch failure. The mimic switch adopts the rapid identification method for online executive failure described in Embodiment 1 to identify whether there is a fault in the current online execute entity, wherein the input flow of the mimic switch is configuration information, specifically, the configuration information includes configuration commands and / or configuration message information

[0039] If there is no fault, the feedback controller will synchronize the configuration of the new online execution body with the current online execution body;

[0040] If there is a fault, the feedback controller obtains the sequence number corresponding to the first inconsistent content in the input agent message queue and the current online execution body message queue, searches and obtains the corresponding historical configuration information from the configuration information queue accordin...

Embodiment 3

[0050] This embodiment provides a computer device, including: a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the program, the online execution described in Embodiment 1 is realized. Rapid identification method of body failure.

Abstract

The invention provides a rapid identification method for an online executor fault, which comprises the following steps that: an input agent module uploads an input stream or a hash value of the inputstream to a feedback controller while distributing the input stream to a plurality of online executors, the feedback controller stores the input stream or the hash value of the input stream into an input proxy message queue according to a receiving sequence; after receiving the input stream, each online executor uploads the hash value of the input stream or the input stream to a feedback controller, and the feedback controller stores the hash value of the input stream or the input stream into a corresponding online executor message queue according to a receiving sequence; when the scheduler schedules the new executor to be on line, the feedback controller compares the hash values of the input streams or the hash values of the input streams in the input proxy message queue and each currenton-line executor message queue, and if the hash values are consistent, it is judged that the current on-line executor does not have a fault; and if not, judging that the current on-line executive bodyhas a fault.

Description

technical field [0001] The invention relates to the field of mimetic switches, in particular to a fast identification method and recovery method for online execution body failures. Background technique [0002] Existing mimic switch devices such as figure 1 As shown, the device uses an arbiter to ensure the correctness of the adjudication result of the switch configuration, and after the arbitration is completed, the hardware configuration process of the switch is completed through the command system. For the case of bypassing the input proxy module and directly attacking the executive body, after the N-1-mode attack or N-mode attack occurs, because the arbiter cannot identify the N-1-mode attack or N-mode attack, the wrong ruling result is regarded as the correct one. The verdict results are output to the command system, thereby affecting the hardware configuration process of the switch. [0003] In order to solve the above existing problems, people have been seeking an i...
