    摘要: A method of filtering packets having a class. The method includes the steps of accessing a table comprised of entries that include an indication to which class a given entry applies. Then there is the step of searching the entries until an entry whose class indication corresponds to a current class of the packet. Next there is the step of forwarding a frame associated with the entry whose class indication corresponds to the class of the packet. A data communication apparatus. The apparatus includes a mechanism for routing or switching packets. The apparatus includes a memory having information for routing or switching the packets. The apparatus includes a mechanism for compaction of information in the memory which removes redundancies in the information.

    摘要: One embodiment of the present invention provides a system that facilitates transmission buffer under-run protection. During operation, the system stores bits of a data frame in a transmission buffer associated with an output port. The system also monitors the state of the transmission buffer and commences transmission of the data frame to the output port prior to complete reception of the data frame in the transmission buffer. The system further determines that the amount of data stored in the transmission buffer is below a predetermined threshold and inserts a number of predetermined unique bit sequences after the partially transmitted data frame, thereby allowing a receiving device to temporarily suspend reception of the data frame and resume reception at a later time without dropping the data frame.

    摘要: A network device is configured to store parameters identifying a respective quality of service (QoS) to apply to corresponding different types of data flows; initiate establishment of a network channel between a source device and a destination device through an optical network; receive first and second data flows destined for the destination device, where the first data flow and the second data flow may have first and second data flow types; identify a first QoS and a different second QoS to apply to the first and second data flows based on the first and second data flow types and based on the parameters; apply the first QoS to the first data flow and the second QoS to the second data flow to form processed first and second data flows; and transmit, via the network channel, the processed first and second data flows towards the destination device.

    摘要: The present invention provides a multi-hop mesh fabric that allows existing systems to be more effectively scaled to increase bandwidth and the number of nodes within the fabric. The multi-hop mesh fabric also provides redundancy for each of the connections between nodes. The multi-hop mesh fabric may be realized in various different architectures including the maximum number of hops within the fabric and the layout of the fabric (e.g., full mesh vs. sparse mesh). The multi-hop mesh fabric may further improve its efficiency by employing various load balancing techniques, different scheduling methods, and other traffic management technologies known by one of skill in the art. Furthermore, the multi-hop mesh fabric may be realized in different environments including intra-devices, inter-device intra-blade, intra-blade intra-system, and inter-system intra-cluster.

    摘要: An interconnect switch stores data messages received from one or more source devices and prioritizes the data messages received from each source device based on the order that the data messages were received from the source device. For each available destination device associated with the interconnect switch, the interconnect switch identifies the data messages with the highest priority that are to be routed to the available destination device and selects one of the identified data messages for the available destination device. The interconnect switch then routes the selected data messages to the available destination devices.
