Improving competitive ratios of online buffer management for shared-memory switches
Koji Kobayashi, Shuichi Miyazaki, Yasuo Okabe (Kyoto Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) The buffer management problem is a kind of online problems, which
formulates the problem of queueing policies of network switches
supporting QoS (Quality of Service) guarantee. For this problem,
several models are considered, and in this paper, we focus on the
model of shared memory switches. We improve the competitive ratio of
the Longest Queue Policy ($LQD$) to $2 - 1/N$, where $N$ is the number
of output ports in a switch.
