On packet scheduling: A novel multi-stage buffering PPS and the Distributed Variable-Length Packet Scheduling (DVLPS) algorithm are present.

分组调度方面：提出了一种新的多级缓存并行分组交换结构和一种分布式变长分组调度算法（DVLPS）。

For processing variable length packet, current routers usually separate the packet into the smaller fixed-size one before buffering, or simply provide the packet with a fixed-length buffer.

现代网络设备常采用固定长度缓冲区机制来缓冲可变长度数据包，或采用信元机制将可变长度数据包进行定长化处理后再完成缓冲操作。
