摘要： A forwarding system includes a first processor coupled to connecting devices using a plurality of uplinks, and a second processor coupled to the connecting devices using a plurality of downlinks. The first processor includes, in a memory, one or more queues each corresponding to the second processor, a priority, and/or to a packet cast type (e.g., unicast or multicast). The first processor is configured to select a particular queue, select a particular uplink based on a comparison of measurements corresponding to respective loads of the plurality of uplinks, and cause a fragment or the entirety of a packet in the particular queue to be forwarded to the second processing device using the selected uplink and corresponding connecting device. The second processor is configured to reassemble the packet, reorder the packet into a flow, and forward the packet from the forwarding system.

摘要： An apparatus includes a receive port unit, a forwarding engine, a transmit port unit, and a reassembly unit. In an embodiment, the packet reassembly unit examines headers in received fragments of a data unit and using the headers to reassemble the data unit, wherein the headers correspond to a protocol layer above an IP-layer. In another embodiment, the packet reassembly unit is located downstream from the forwarding engine in a packet forwarding pipeline, and the forwarding engine skips processing fragments received subsequent to a first received fragment.

摘要： Resources allocated to a group of ports include a plurality of storage regions. Each storage region includes a committed area and a shared area. A destination storage region is identified for a packet. A packet queuing engine stores the packet in the committed area of the determined destination storage region if it has a first drop precedence value, and if available storage space in the committed area exceeds a first threshold. The packet queuing engine stores the packet in the shared area of the determined destination storage region if the packet is not stored in the committed area, and if available storage space exceeds a second threshold defined by the packet's drop precedence value. If the packet is not stored either in the committed or shared area, it may be dropped.

摘要： In a method for processing packets, a storage region for a packet is determined based on a queue with which the packet is associated. The storage region includes a committed area reserved for storage of packets associated with the queue, and an area that is shared by multiple queues for packet storage. A first part of the packet is stored in the committed area, a second part is stored in the shared area, and both parts are accounted for. A network device for processing packets comprises a plurality of queues and a storage area including a committed area and a shared area. The network device further comprises a packet queuing engine configured to store a first part of a packet in the committed area, store a second part of the packet in the shared area, and account for the storage of the first and the second parts of the packet.
