摘要: We consider scheduling packets with values in a capacity-bounded buffer an online setting. In this model, there is limited capacity $B$. At any time, the cannot accommodate more than $B$ packets. Packets arrive over time. Each packet associated non-negative value. leave only because they are either sent or dropped. Those that have left will not be reconsidered for delivery more. each time step, at most one can sent. The order which should comply of their arrival objective to maximize total value manner. paper, we study variant FIFO buffering model packet's 1 $\alpha > 1$. present deterministic memoryless 1.304-competitive algorithm. This algorithm has same competitive ratio as presented (Lotker and Patt-Shamir. PODC 2002, Computer Networks 2003). However, our simpler does employ marking bits. idea used novel different from all previous approaches applied general its variants. do proactively preempt when new arrives. Instead, may 1-value contains sufficiently many $\alpha$-value
