摘要： A control system for packet transmission. A forward control unit receives a packet providing a port count through an input port and implements a lookup operation. A queue control unit determines whether the port count is greater than a first predetermined value, and, if not, outputs the packet through a first port, and, if so, sends a first message. A multicast forward control unit receives the first message, adds one to a first packet count, determines whether the first packet count is greater than a threshold value, and, if so, sends a stop forward message to the forward control unit but does not send a grant message. The forward control unit receives the stop forward message and does not transmit subsequent packets to the first port but to a second port directly.

摘要： 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.
