Abstract

Due to the network resources conflicting, optical burst switching (OBS) network would raise some contentions, which is often resolved by head-drop schemes since they are more simple and intuitional. However, the existing head-drop schemes have two inherent defects, i.e., pseudo-contention and excessive-drop. Besides, they seldom consider how to support QoS. In consequence of the shortcomings, this paper proposed the QoS-aware head-drop scheme, which can selectively discard the head part of contending burst or the entire burst according to the priority and the truncated burst relative length, i.e., the ratio to the original burst length. The simulation results show that it is able to overcome the mentioned shortcomings, and to provide QoS guarantee.
