The switching net. work is an important. classic research area in t. ele­ communication and comput. er net. works. It. s import. ancc st. ems from both theory and practice. In fact, some open problems, such as Benes conjec­ ture on shuffle-exchange networks and Chung-Rmis conjecture on multi­ rate rearrangeability, still attract many researchers and the further de­ velopment in optical networks requires advanced technology in optical switching networks. In 1997, we had a workshop in switching networks held in NSF Sci­ ence and Technology Center in Discrete Mathematics and Theoretical Computer Science (DIMACS), at Princeton University. This workshop was very successful. Many participants wished to have a similar activity every two or three years. This book is a result of such a wish. We are putting together SOllle important developments in this area during last. several years, including articles ill fault-tolerance, rearrang{ | Switching Networks by Ding-zhu Ding-Zhu Du, Hardcover | Indigo Chapters
