Provided is a control method for an advanced configuration and power interface (ACPI) in a computer system. The computer system comprises a processor and a bus master, wherein the processor, as defined by the ACPI specification, has a first state (Cstate), a second state (Cstate), a third state (Cstate), a fourth state (Cstate) and a fifth state (Cstate). The method comprises enabling the processor to run in the Cstate when a request from the bus master is issued before the processor enters the Cstate, or enables the processor to ignore the Cstate and complete the Cstate when the request from the bus master is issued at the Cstate and before entering the Cstate.

A method for processing packets of a VLAN in a network switch is provided. The VLAN comprises a plurality of physical LANs and are divided into a plurality of subnets. The method comprises the steps of: receiving a packet through an ingress port of the network switch, wherein the packet is tagged with a VID of the VLAN; finding a VLAN member according to the VID, wherein the VLAN member represents all ports of the network switch dedicated to serving packets of the VLAN; finding a forwarding scope according to the ingress port, wherein the ingress port is one of the ports dedicated to serving packets of a first subnet of the VLAN and the forwarding scope represents all ports of the network switch dedicated to serving packets of the first subnet; and determining an egress port of the packet according to both the VLAN member and the forwarding scope.

The invention provides a method for implementing varying service quality grades in a network switch. First, a plurality of users of the network switch is classified into a plurality of service quality grades according to a contributing factor of the plurality of the users. Each of the plurality of users is then connected to the network switch via one of a plurality of ports of the network switch according to its service quality grade. An original priority of a packet in the network switch is then determined. An adjusted priority of the packet is then determined according to both the original priority of the packet and a priority adjustment table of an ingress port of the packet. 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 and the adjusted priority.
