本文提出了具有纵横输入（ＣｒｏｓｂａｒＩｎｐｕｔ）互连方式和输入缓冲（ＩｎｐｕｔＢｕｆｅｒｅｄ）结构的递归Ｋｎｏｃｋｏｕｔ交换网络（ＣＩＢＲＫＳ）．通过采用纵横输入互连方式可减少内部小交换单元的数目，并可使信元传送顺序不会受群输出端口数目的影响．而通过在每个输入端放置缓冲器可在保持丢失率性能不变的情况下，可使整个交换网络的级数减少，从而也就减少了信元在群网络中的传输时延．另外，在该结构中，通过把信元滤址的功能从每个小交换单元中提取出来放在每个输入端口，又进一步减少了小交换单元的功能．通过比较，我们认为，作为大规模ＡＴＭ交换网络结构，ＣＩＢＲＫＳ结构比传统的ＲＫＳ结构具有较好的性能／复杂度特性．
In this paper, a recursive Knockout exchange network (CIBRKS) with CrosbarInput interconnection and InputBufered structure is proposed. Through the use of vertical and horizontal input interconnection can reduce the number of internal small exchange unit, and the cell transmission order will not be affected by the number of output ports of the group. By placing a buffer at each input, the number of stages in the entire switching network can be reduced while maintaining the same loss rate performance, thereby reducing the transmission delay of the cells in the group network. In addition, in this structure, the function of the small exchange unit is further reduced by extracting the function of cell filtering from each of the small exchange units for each input port. By comparison, we believe that as a large-scale ATM switching network structure, CIBRKS structure has better performance / complexity characteristics than the traditional RKS structure.
