• 演講題目：Diverse Routing in Heterogeneous Optical Transport Network
•  Abstract：Network planners are often requested to provision multiple physically-diverse high-speed circuits over a large carrier's intercity DWDM network, which consists of multiple layers and heterogeneous vendor systems. Optimally provisioning such circuits while avoiding shared risk link group (SRLG) failures is an NP-hard problem. In this talk, I will describe a novel hybrid two-step approach: pre-processing with Integer Linear Programming (ILP) for diverse routing and post-processing for regenerator placement and wavelength assignment. This approach has been implemented in a network planning tool. According to our experiments, most of the cases for a typical large carrier's core transport network can be solved within 1 minute, even with tens of thousands of binary decision variables, which allows interactive use by network planners.
• Biography：Angela L. Chiu received her S.M and Ph.D. degrees, both in electrical engineering and computer science from MIT, Cambridge, MA, in 1993 and 1997, respectively. She was a research staff member in the Optical Communication Technology group of MIT Lincoln Laboratory from April to November 1997. In November 1997, she joined AT&T Labs and lead architecture and design on IP QoS, MPLS, restoration and control plan design for IP over Optical architecture. Her team pioneered the first IP class of service in 1999. Now she is a principal inventive scientist at Network Evolution Research Department. During 2001 and 2002, she was a principal architect at Celion Networks, an optical start-up. Dr. Chiu has published extensively in many technical journals and conferences and has served as conference and program chairs for numerous conferences. She holds fifteen U.S. patents. She is a co-author of 6 IETF international standards. Her research interests include architecture, design, and analysis of IP, Ethernet, and optical networks, software-defined networks, network function virtualization.
