摘要： A method for selectively controlling the flow of data through a network device is discussed. The network device has a plurality of ports, with each port of the plurality of ports having a plurality of priority queues. Congestion at one priority queue of the plurality of priority queues is detected and a virtual channel message is sent to other network devices connected to the network device causing data destined for the one priority queue to be halted. After the congestion at the one priority queue has abated, a virtual channel resume message is sent to the other network devices.

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： The present invention is directed to a system and method of sending packets between ports on trunked network switches. A trunk connection is provided between first and second switches, with the trunk connection including at least two of the plurality of ports from the first switch being connected to at least two of the plurality of ports of the second switch. A packet is received at an ingress submodule of the first switch, and a lookup is performed on one of a source address and a destination address of the packet based upon a lookup table provided in the ingress submodule. A rules tag bit is then compared to a rules table defining which trunk port of the trunk bundle will be used for communication. The rules tag determines which address bits will be used to identify a trunk port for communication.
