A novel optical burst switching (OBS) high speed network architecture has been proposed.To verify its feasibility and evaluate its performance,lust-enough-time (JET) signaling has been considered as a high performance protocol.In the proposed architecture,to avoid burst losses,firstly,a short-prior- confirmation-packet (SPCP) is sent over the control channel that simulates the events that the actual packet will experience.Once SPCP detects a drop at any of the intermediate nodes,the actual packet is not sent but the process repeats.In order to increase network utilization,cost effectiveness and to overcome some limitations of conventional OBS,inherent codes (e.g.,orthogonal optical codes (OOC)), which are codified only in intensity,has been used.Through simulations,it shows that a decrease in burst loss probability,cost effectiveness and a gain in processing time are obtained when optical label processing is used as compared with electronic processing.

诸位看官,不久前,哥伦比亚发生了打砸华商店铺的恶性事件。当地人举行抗议游行,指责华商抢占其生意、威胁其生存,声称要将华人华商“踢出哥伦比亚”。  对中国人来说,这样的新闻已经算不得“新闻”了!因为近年来,海外类似暴力侵害华商利益的事件不断发生,只是时间、地点不同而已。  每次发生此类事件,国内舆论都会哗然,很多民众也都义愤填膺要求惩治凶手。作为勤劳友善的龙的传人,为何走出国门反而总是成为排挤打压的
