摘　　要：在分组间插的OTDM局域网中 ,光分组的发送和接收不仅受限于电子处理速度的限制 ,而且受限于光分组压缩解压缩器的结构。本文提出了使用分组重排和光时分解复用器构建并行解压缩器来缓解该受限问题的方案。同时 ,通过对传统的周期预留多址接入CRMA(CycleReservationMultipleAccess)协议进行进一步扩展 ,得到了在受限条件下既能避免将数据分组简单丢弃、又能获取很高网络性能可行的高速网络接入控制协议。In slotted OTDM system, the limitation of transmission and receiving not only arises from electronic processing rate but also from the compression and de-compression ability. A parallel de-compression scheme is proposed to relieve the limitation. The extension of corresponding medium access control (MAC) protocol,Cycle Reservation Multiple Access (CRMA),is also discussed and the new protocol not only avoids discarding data packet simply but also keeps the high network utility of the high speed LAN under the limitation.
