报告内容摘要:

台湾清华大学「拔尖计划」的研究团队,近年来从事光队列的研究。大家都知道光通讯的时代已经到临,然而全光网络的时代却尚未来临。主要的原因是目前因特网传送数据的方式是先储存后传送(store-and-forward)。然而如众所知,光是不断以光速在前进,如何储存呢? 简单的想法就是把光「导」到一段「光纤」里,让光在里面兜圈子,直到适当的时机才将光放出来。如果只有单一光封包(optical packet),这样的想法还容易,但因特网代表的是几乎无限不断涌进的光封包,而让这些光封包以有秩序的方法传出,便需要让这些光封包排队(正如同我们搭乘公交车和捷运一样)。光队列就是能让光封包排队的机制,而光队列理论就是建造光队列的理论。此次演讲我们将简介两种光队列的建造理论: linear compressors 和priority queues。

 

Bio

Cheng-Shang Chang received the B.S. degree from the National Taiwan University, Taipei, Taiwan, in 1983, and the M.S. and Ph.D. degrees from Columbia University, New York, NY, in 1986 and 1989, respectively, all in Electrical Engineering. From 1989 to 1993, he was employed as a Research Staff Member at the IBM Thomas J. Watson Research Center, Yorktown Heights, N.Y. In 1993, he joined the Department of Electrical Engineering at National Tsing Hua University, Taiwan, where he is a Chair Professor. His current research interests are in high speed switching, communication network theory, and mathematical modeling of the Internet.  Dr. Chang received an IBM Outstanding Innovation Award in 1992, an IBM Faculty Partnership Award in 2001, and Outstanding Research Awards from the National Science Council, Taiwan, in 1998, 2000 and 2002, respectively. He is the author of the book ``Performance Guarantees in Communication Networks,'' and the coauthor of the book ``Principles, Architectures and Mathematical Theory of High Performance Packet Switches''. He is currently an Associate Editor for IEEE Transactions on Networking and a Fellow of IEEE.
