Packets to be transmitted from a network device are buffered in a queue in a first packet memory. In response to detecting congestion of the queue in the first packet memory, a group of the plurality of packets is transferred from the first packet memory to a second packet memory configured to buffer a portion of traffic bandwidth supported by the network device. Before a packet among one or more groups of the plurality of packets is transmitted from the network device, the packet among the one or more groups of the plurality of packets is transferred from the second packet memory back to the first packet memory. Packets transferred from the second packet memory back to the first packet memory are retrieved from the first packet memory and forwarded to one or more network ports for transmission of packets from the network device. 在第一分组存储器中的队列中对将从网络设备中传输的分组进行缓冲。响应于检测到第一分组存储器中的队列的拥堵，将多个分组的一个群组从第一分组存储器转移到第二分组存储器，该第二分组存储器被配置为对由网络设备所支持的业务带宽的一部分进行缓冲。在从网络设备传输多个分组的一个或多个群组之中的分组之前，将该多个分组的一个或多个群组之中的分组从第二分组存储器转移回到第一分组存储器
