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： A header analyzer unit generates attribute information regarding headers of a data unit. The header analyzer unit includes a programmable memory unit having a content addressable memory (CAM) with an input to receive a first portion of the data unit and a second portion of the data unit. The programmable memory unit also includes a memory separate from the CAM and coupled to an output of the CAM. The CAM stores indications of locations within the memory separate from the CAM, and the memory separate from the CAM programmably stores header attribute information regarding a plurality of different types of headers for data units having different formats.

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.
