【摘要】 光突发交换(OBS)是实现IP／DWDM网络的一种极有前途的方案。该文着重讨论了光空发交换(OBS)网络中单向资源预留的方式。文中首先介绍了著名的JET(Just Enough Time)，提出了一种新的单项资源预留方式Just Little Time(JLT)，它不但能使用偏转路由，还能有效利用Fiter Detag Line(FDL)延时来弥补偏移时间的不足，只需使用很小的初始偏移时间，降低了数据在网络中的延时。随后，文章讨论了使用偏移时间增量来实现区分服务的方法。计算机仿真结果证明了所提方法的有效性。更多还原

【Abstract】 Optical Burst Switching (OBS) is a promising solution for realizing IP/DWDM. This paper focuses on the one-way delayed reservation scheme. As a well-known scheme, JET (Just Enough Time) is described first. Then a new scheme called Just Little Time(JLT) is introduced in this paper. JLT is compatible with deflection routing and has no offset redundancy. To support service differentiation, offset time increments are adopted by JLT. JLT proves to be effective via computer simulations.更多还原
