Front-Range GigaPOP History Current Members Commodity Internet Status * 07/16/96 Front-Range GigaPOP History Current Members NCAR,CSU,DU,UCD,HSC,NOAA,UCB,UW,CSM,State of Colo. Commodity Internet Status 3 Carriers C & W @ 155Mbps AT&T @ 155Mbps UUNet via NOAA @ 15Mbps (BPOP only) Began in fall of 1999 Equipment and lines located in Denver Only 3 members Cost of internet connectivity went up/no free rides Long battle to get multiple carriers BPOP is composed of NOAA/NIST and NCAR Gives NCAR a back-door internet access in Boulder 11/7/2018 *

Web100 Collaborative Research Project SC2000 - initial Demo * 07/16/96 Web100 Collaborative Research Project SC2000 - initial Demo http://www.web100.org/ Project Goals: To enable ordinary network users to attain full network data rates without help from network experts. To develop the software components necessary for a high performance network host software environment. Reasons for Poor Network Performance:The host system software is optimized for low bandwidth. There is a lack of instrumentation and tools to diagnose performance issues at end hosts. How do we plan to achieve our goals: The environment will run common TCP-based applications at the fastest rate appropriate for the underlying network infrastructure. The TCP performance tuning transparency will be achieved by embedding the appropriate diagnostics and automatic controls in the end system operating system at a level invisible to the user. Create a window into the network to better see and diagnose network performance components.
