This is a service-provider oriented panel hosted at NANOG52 in Denver, CO, that I coordinated (with Nina Bargisen of TDC with help from Phil Griston, Cariden, and Timothy Hu, WANDL) and moderated/Chaired. The panel involved excellent presentations by Tom Lundstrom (Qwest) and Duke Fisher (Verizon) on how they were using network planning and design tools to effectively handle large-scale design..
