摘要： A network switch for switching packets from a source to a destination includes a source port for receiving an incoming packet from a source, a destination port which contains a path to a destination for the packet, and a filter unit for constructing and applying a filter to selected fields of the incoming packet. The filter unit further includes filtering logic for selecting desired fields of the incoming packet and copying selected field information therefrom. The filtering logic also constructs a field value based upon the selected fields, and applies a plurality stored field masks on the field value. The switch additionally includes a rules table which contains a plurality of rules therein. The filtering logic is configured to perform lookups of the rules table in order to determine actions which must be taken based upon the result of a comparison between the field value and the stored filter masks and the rules table lookup.

摘要： A method for avoiding out-of-ordering of frames in a network, wherein the method includes the steps of providing at least one first type of queue in a network switch, providing at least one second type of queue in a network switch, and receiving an incoming packet. The method further includes first storing the incoming packet in the at least one first type of queue if the packet is from a first source, second storing the incoming packet in the at least one second type of queue if the packet is from a second source, and sending the incoming packet to a desired destination. Additionally, a method for avoiding out-of-ordering of frames in a network including the steps of receiving an incoming packet at a network switch, determining if the incoming packet is from a high speed source, first storing the incoming packet in a first type of queue, if the incoming packet is from said high speed source, and second storing the incoming packet in a second type of queue, if the incoming packet is from a lower speed source. Additionally, a step of sending the incoming packet stored in one of the first queue and the second queue using a first-in first-out operation.
