Problems solved by technology

In terms of security, since VLAN and VPN technology can only achieve logical isolation, physically all data is in the same physical channel, and there is a possibility of being intercepted by others, so the overall security is not very reliable

Abstract

The invention relates to a power service isolation transmission device and method based on optical wavelength and optical packet switching. Power service transmission is directly carried out on an optical path, a plurality of physically isolated single-wavelength optical paths can be established in a single pair of optical fibers by utilizing the multi-wavelength transmission characteristic of theoptical fibers, and the transmitted power service is loaded to different wavelengths, so that complete physical isolation can be realized, and the hidden danger of service security isolation caused by logic isolation is eliminated; and the security, confidentiality and reliability of the power business data are improved.

Description

technical field [0001] The present invention relates to the field of power system communication, in particular to a power service isolation transmission device and method based on optical wavelength and optical packet switching. Background technique [0002] Power system communication services are mainly divided into power grid operation and enterprise management services according to their functions and characteristics. Power grid operation business is divided into operation control business and operation information business; enterprise management business is further divided into information business and office business. These services all rely on the support of the communication network, but the requirements for communication are not the same. For example, the operation control business, as a part of power grid control, is directly related to the security of the power grid, so the requirements for communication transmission delay and channel reliability are extremely hig...
