Embodiment Construction

[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0056] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0057] According to the implementation form of a method for identifying friend or foe based on a physical layer link of the present invention, based on the cable detection technology, at the receiving end and the sending end of the physical layer of the OSI reference model, the friend or foe status of the receiving end and / or the sending end is checked by an identification algorithm judge. The identification method using this scheme is in line with / compatible with the existing standards and systems of cable detection technology; the execution process of IFF is hidden in the common ...

Abstract

The invention discloses friend or foe identification methods based on a physical layer link. On the basis of a cable detection technology, at a receiving end and a transmitting end of a physical layerof an OSI reference model, a friend or foe state of the receiving end and / or the transmitting end is judged through utilization of an identification algorithm. According to the friend or foe identification methods based on the physical layer link provided by the invention, a friend or foe identification algorithm can be designed in the physical layer of the OSI reference model, and on the basis of the existing cable detection technology, a friend or foe identification result is obtained through interaction with opposite equipment connected with a cable.

Description

technical field [0001] The invention relates to a method for identifying friend or foe in a transmission link. More specifically, the present invention relates to a method for identifying friend or foe based on physical layer links in the case of cable detection. Background technique [0002] In order to meet the massive data transmission needs of a large number of devices, the development of wiring (transmission line) systems at home and abroad has gone through three stages: the twisted pair stage, the cable and twisted pair stage, and the optical fiber stage. The on-off of the transmission cable affects whether the data carried by it can be transmitted normally. In order to shorten the service data interruption time caused by the physical layer link failure as much as possible, a preventive technology that can directly detect the physical layer link status (that is, the line Cable detection technology) came into being. Transmission cables carrying electrical and optical ...
