Why?
Current DS-3 (45 Mbps) backbone nearing capacity - need more bandwidth
Community College video project - need more bandwidth
Research projects at some campuses - need more bandwidth
![Page 4: 4CNet Update June 30, 1999 Dave Reese Director, Network Planning & Development “Building tomorrow’s networks today”](https://reader030.vdocuments.mx/reader030/viewer/2022032703/56649d1f5503460f949f2cc9/html5/thumbnails/4.jpg)
More Bandwidth
Most current Sprint/AT&T DS-3 circuits being replaced by OC-3 (155 Mbps)
OC-12 (622 Mbps) between Los Angeles and San Diego
New vendor: Qwest (http://www.qwest.net/)
![Page 5: 4CNet Update June 30, 1999 Dave Reese Director, Network Planning & Development “Building tomorrow’s networks today”](https://reader030.vdocuments.mx/reader030/viewer/2022032703/56649d1f5503460f949f2cc9/html5/thumbnails/5.jpg)
More Reliability
Most of the backbone will move off CSU campuses into Qwest points of presence (“POPs”)
Telco-quality facilities: UPS, generator, etc. Campuses will connect to Qwest POPs

“It has to be done when?”
Western backbone: July 1999 Northern backbone: October 1999 Eastern backbone: October 1999

In the metro areas
Pacific Bell providing OC-48 (2,400 Mbps) SONET rings in LA, SF, SD areas
Connect CSU campuses, Qwest POPs at OC-3c, OC-12c
Some campuses (LB, SB, POM, SON, HUM) are too ‘far’ from the rings to be included
![Page 8: 4CNet Update June 30, 1999 Dave Reese Director, Network Planning & Development “Building tomorrow’s networks today”](https://reader030.vdocuments.mx/reader030/viewer/2022032703/56649d1f5503460f949f2cc9/html5/thumbnails/8.jpg)
What’s SONET?
High-speed optical (fiber) networking Ring topology means that circuit failures
don’t cause outages -- traffic re-routes around the ring in less than a second

The Big Picture
We’re building the biggest university network in the country
And making it better, faster, more reliable
