    • Described embodiments process data packets received by a network switch coupled to an external buffering device. The network switch determines a queue of an internal buffer of the network switch associated with a flow of the received packet and determines whether the received packet should be forwarded to the external buffering device. If the received packet should be forwarded to the external buffering device, the network switch sets an external buffering active indicator indicating that the network switch is in an external buffering mode for the flow, tags the received packet with metadata, and forwards the packet to the external buffering device. The external buffering device stores the forwarded packet in a queue of a memory of the external buffering device corresponding to the tagged metadata of the forwarded packet. The network switch processes packets stored in the internal buffer of the network switch.
    • 描述的实施例处理由耦合到外部缓冲设备的网络交换机接收的数据分组。 网络交换机确定与接收到的分组的流相关联的网络交换机的内部缓冲器的队列,并确定接收到的分组是否应转发到外部缓冲设备。 如果接收到的数据包应该转发到外部缓冲设备,则网络交换机设置外部缓冲活动指示符,指示网络交换机处于流量的外部缓冲模式,用元数据对接收到的数据包进行标记,并将数据包转发到 外部缓冲设备 外部缓冲装置将转发的分组存储在与所转发的分组的标记的元数据相对应的外部缓冲装置的存储器的队列中。 网络交换机处理存储在网络交换机的内部缓冲区中的数据包。

    • Described embodiments provide a network processor having a hardware accelerator that identifies a received packet and, based on a flow identification associated with the received packet, might pre-fetch pre-established portions of data from the received packet into local data memory (e.g., local data cache) for processing by a general purpose processor core. In addition to the packet data, the software necessary for the general-purpose processor core to process the data might also be pre-fetched into local instruction memory (e.g., local instruction cache). The flow identification might be used to select different portions of the packet and different software to be pre-fetched.
    • 所描述的实施例提供一种具有硬件加速器的网络处理器,该硬件加速器识别所接收的分组,并且基于与所接收的分组相关联的流标识可将预先建立的数据部分从所接收的分组预取到本地数据存储器(例如,本地 数据缓存),用于由通用处理器核心处理。 除了分组数据之外,通用处理器核心处理数据所需的软件也可以被预取到本地指令存储器(例如,本地指令高速缓存)中。 流标识可以用于选择分组的不同部分和要预取的不同软件。
