In order to support efficiently the fast-growing demand for transmission capacity, optical packet-switched systems seem to be strong candidates as they allow fast dynamic allocation of WDM channels combined with a high degree of statistical resource sharing. In this work, we propose the architecture of an input/shared-buffered optical packet switching node, for all-optical switching of IP traffic flows. Since a limited hardware complexity is a key requirement for all-optical switches, due todoi:10.1109/glocom.2002.1189133 dblp:conf/globecom/BregniGP02 fatcat:eeyci32bvjdqdbdowuf4zmtahe
