(Switch's Priority for Invention Background: The transfer work for the excellent and negative f1Ml, the traffic setting is nothing more than personal use: :: brother. The priority board for the purpose is not to provide users with bombs. The exchange seems dumb and may have high priority, which is optional. For example, if a company's general business department wants to send financial reports, it will give priority to information, but financials, such as the transmission of specific information, cannot be achieved. It is also necessary to address the characteristics of the network switch: 1 amphibious. The job is to provide a solution to the car father's good. The purpose and summary of the invention: The main purpose of the switch to the network exchange is: Propose a suitable method for controlling the priority of Internet delivery. Another object of the present invention is to disclose a method of transferring M rights and controlling wealth. ^ In order to achieve the above-mentioned object, the present invention uses various different ways to transfer priority. The selection control includes: (a) based on the port (port) as the 'Frame' sent by any user connected to the port to give a tag indicating the priority level; (b) With MAC (Medium
