摘要: 光突發(fā)交換(OBS)是實(shí)現(xiàn)IP/DWDM網(wǎng)絡(luò)的一種極有前途的方案。該文著重討論了光空發(fā)交換(OBS)網(wǎng)絡(luò)中單向資源預(yù)留的方式。文中首先介紹了著名的JET(Just Enough Time)，提出了一種新的單項(xiàng)資源預(yù)留方式 Just Little Time (JLT)，它不但能使用偏轉(zhuǎn)路由，還能有效利用Fiter Detag Line（FDL）延時(shí)來(lái)彌補(bǔ)偏移時(shí)間的不足，只需使用很小的初始偏移時(shí)間，降低了數(shù)據(jù)在網(wǎng)絡(luò)中的延時(shí)。隨后，文章討論了使用偏移時(shí)間增量來(lái)實(shí)現(xiàn)區(qū)分服務(wù)的方法。計(jì)算機(jī)仿真結(jié)果證明了所提方法的有效性。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.
