Communication method capable of simultaneously supporting 8G speed and 16G speed of FC protocol

Abstract

The invention discloses a communication method capable of simultaneously supporting the 8G speed and the 16G speed of an FC protocol. When data are input, the data of different speeds are identified, decoding analysis processing is conducted according to the FC protocol, and 16G port data are mapped to be consistent with 8G port data through mapping, and unified scheduling process is facilitated. In the output process, inverse mapping in a coding mode needs to be conducted on outputting of a 16G physical port again, and the standard encoding requirement corresponding to the relevant speed is met. Related protocol processing is conducted on interfaces of different speeds, mapping relations between different protocols are innovatively designed, the 8G speed and the 16G speed can be conveyed to exchange equipment in a unified coding mode for conducting scheduling exchange, relevant design is improved in the scheduling design, and data transmission at different speeds can be mutually matched.
