Abstract:
1. A method for implementing varying service quality grades in a network switch, comprising the steps of: classifying a plurality of users of the network switch into a plurality of service quality grades according to a contributing factor of the plurality of the users; connecting each of the plurality of users to the network switch via one of a plurality of ports of the network switch according to its service quality grade, wherein each of the plurality of ports corresponds to one of the plurality of service quality grades; determining an original priority of a packet in the network switch, wherein the packet is sent from one of the plurality of users and received by the network switch via an ingress port, and the ingress port is one of the plurality of ports; and determining an adjusted priority of the packet according to both the original priority of the packet and a priority adjustment table of the ingress port of the packet; wherein each of the plurality of ports has a corresponding priority adjustment table, and each of the priority adjustment tables includes a mapping relationship between the original priority of the packet and the adjusted priority of the packet.
