摘要：This paper studies the Ant-based packet contention resolution schemes for the singlestage
shared FDL optical packet switches. A new Ant-based algorithm is proposed, namely delaybased
FDL assignment and number¨Cdelay-based FDL assignment. The proposed algorithm can makes
FDLs and output port reservation so as to improve the cell-loss rate under various traffic loads. The
proposed contention resolution scheme is shown to effectively resolve packet contention and achieve
good performance by requiring minimum fiber delay length.
