摘要： In particular embodiments of the present invention, a method for bypassing an output queue structure of a switch is provided. In a particular embodiment, a method for bypassing an output queue structure of a switch includes receiving a packet at an input port of a switch, storing the packet in a memory of the switch, and generating a forwarding request associated with the stored packet and with a particular output port of the switch, the forwarding request identifying the location in the memory of the stored packet. The method also includes determining whether to cause the forwarding request to bypass an output queue structure associated with the particular output port. The method further includes, using the forwarding request, retrieving from the memory the packet associated with the forwarding request and sending the retrieved packet from the particular output port.

摘要： In a link aggregation group aggregating a number of ports of a network element, the network element may distribute frames among the ports using a distribution function that operates according to information in the received frames. The network element may apply one of several different distribution functions and, at appropriate times, change the selected distribution function to effect a different distribution of frames among the ports.

摘要： Each transmission port module includes a plurality of queues in association with combinations of a priority and a VLAN number. An accumulated-amount storage unit stores a total size of packets accumulated in queues associated with the same priority. A threshold storage unit stores a threshold of a total packet accumulated amount for each queue. When a packet is received, whether to discard the packet is determined based on a total packet accumulated amount stored in the accumulated-amount storage unit in association with a priority set for the packet and the threshold stored in the threshold storage unit in association with a storage-destination queue of the packet.

摘要： A system for queuing packets written to memory for switching includes a data memory logically divided into multiple blocks. The system also includes multiple input ports each operable to receive packets and write the packets to the data memory. The system also includes multiple output ports each having a memory structure and one or more output queue pointers. The memory structure includes multiple memory structure entries that each correspond to one of the blocks. Each of the memory structure entries includes a memory structure next pointer that can link to another one of the memory structure entries. An output queue pointer can link to one of the memory structure entries, and the output queue pointers and memory structure next pointers form output queue linked lists. Each of the output ports can read packets stored in the data memory using the output queue linked lists and communicate the packets.

摘要： A system for switching packets in a high-speed switching environment includes one or more memory structures, multiple input structures that can each write to each of the one or more memory structures, and a first switching structure that couples the input structures to the one or more memory structures. The system also includes multiple output structures that can each read from each of the one or more memory structures and communicate a first portion of a packet to a first component of a communications network before an input structure has received a second portion of the packet from a second component of the communications network. The system also includes a second switching structure that couples the plurality of output structures to the one or more memory structures. The second switching structure is coupled to the one or more memory structures by a first number of links and coupled to the plurality of output structures by a second number of links, and the first number of links is twice or more the second number of links.
