History
Current Members
NCAR,CSU,DU,UCD,HSC,NOAA,UCB,UW,CSM,State of Colo.
Commodity Internet Status
3 Carriers
C & 155Mbps
155Mbps
UUNet via 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

Front-Range GigaPOP - Cont.
Abiline Connectivity at 155Mbps
vBNS connectivity at 155Mbps
Caching
Abiline/Internet 2
vBNS connects the super computing centers
Caching at the FRGP gets about 3-5% hits
Made up of a rack of servers and disks
NCAR is now well conected

Boulder Research & Administration Network
History
Connects NOAA, NIST, UCB, City of Boulder, and NCAR together
NCAR paths from ML, Pearl, FL
MSS Extension to MMM, ATD
Took 4 years to develop & build
cooperation between all parties
28 strands of dark fiber
12 for the city
Been up for about 1 year
gives us unlimited speed between the sites

Web100
Collaborative Research Project
SC initial Demo
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.
