Tim Brown@DIAMONDCHICAGO 08/16/99 06:56 PM I need some general questions about ns answered. Specifically: 1. How suitable is ns for a business (i.e. non-R&D facility) to use for network modeling and simulation in terms of man-hours, support, etc. 2. Does ns answer questions about QoS on IP networks, specifically RRR, MPLS, WRED, DRR? Thanks, Tim Brown
