有界缓冲区中的有界延迟分组调度

Bounded Delay Packet Scheduling in a Bounded Buffer

Stanley P. Y. Fung

摘要:

我们研究了在有界延迟模型中的QoS网络交换机中的缓冲区管理问题,其中每个数据包都与一个权重和一个截止日期相关联。我们认为更现实的情况下,网络交换机有一个有限的缓冲区大小。对于多个缓冲器的情况,已知9.82竞争算法(Azar和Levy,SWAT'06)。最近,对于单个缓冲器的情况,已知3-竞争确定性算法和2.618-竞争随机算法(Li,INFOCOM'09)。在本文中,我们给出了一个简单的确定性2-竞争算法的情况下,一个单一的缓冲区。

英文摘要:

We study the problem of buffer management in QoS-enabled network switches in the bounded delay model where each packet is associated with a weight and a deadline. We consider the more realistic situation where the network switch has a finite buffer size. A 9.82-competitive algorithm is known for the case of multiple buffers (Azar and Levy, SWAT'06). Recently, for the case of a single buffer, a 3-competitive deterministic algorithm and a 2.618-competitive randomized algorithm was known (Li, INFOCOM'09). In this paper we give a simple deterministic 2-competitive algorithm for the case of a single buffer.
