摘要： Various example embodiments are disclosed. According to an example embodiment, an apparatus may include a switch fabric. The switch fabric may be configured to assign packets to either a first flow set or a second flow set based on fields included in the packets. The switch fabric may also be configured to send a first packet from the first flow set to a first flow set destination via a first path. The switch fabric may also be configured to determine, based at least in part on delays of the first path and a second path, whether sending a second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination, the second packet having been received by the router after the first packet. The switch fabric may also be configured to send the second packet to the first flow set destination via the second path based at least in part on the determining that sending the second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination.

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： A method of forwarding data in a network switch fabric is disclosed. An incoming data packet is received at a first port of the fabric and a first packet portion, less than a full packet length, is read to determine particular packet information including an opcode value. The opcode value allows the fabric to determine the packet type, such a a whether the packet is a broadcast packet, a unicast packet, a multicast packet, etc. Based on the opcode value read, a particular forwarding table of a plurality forwarding tables is read and an egress port bitmap is determined based on entries read from the particular forwarding table. The incoming data packet is then forwarded based on the egress port bitmap. In addition, the architecture of the switch fabric is also disclosed.
