摘　　要：多通道信元重组是网络设备设计中典型的缓冲区管理操作,广泛用于ATM接口和Crossbar交换网络的设计中。本文基于共享缓冲区结构,提出多通道信元的重组和调度算法。理论分析表明,这种方法具有较小的缓冲区要求和确定的重组延时上限。本文最后介绍用FPGA实现该结构的方法,该方法已经在核心路由器ATM接口设计中得到成功应用。Multi-charmel cell reassembly is a kind of typical technology for buffer management in network equipment which is widely used in ATM interfaces and the design of crossbar switches. This paper presents a multi-channel cell reassembly and scheduling algorithm based on the shared-memory structure. Theoretical analysis show that the structure has fewer volume demand of the buffer and determ2nate reassembly delay bound. Finally, we introduce the implementation of this structure using FPC-A, and apply it to the ATM interface design of core touters successfully.
