About the Project
Was State
One or more T1’s for Internet
High School, T1s forVoice
Elementary, 4 POTs lines Videos Delivered by car
Voice
Fractional T1 for data
Voice◦ Phone in every classroom
Internet◦ Increased Bandwidth to each school
Administrative Data Network◦ Increased Bandwidth to each school
Video◦ Delivery on Demand
abilties◦ Availability, reliability, affordability, usability
Project Goals
Status Quo◦ Increase bandwidth of existing system
Telephone Architecture◦ SONET Rings, ATM Switches
Private Microwave Ethernet Architecture
◦ Dark Fiber, gigabit and 10gigabit Switches
Design / Architecture Trade-Offs
The Design / Is State
Gigabit fiber rings enables:◦ Voice over IP & on-net dialing◦ Data / Internet◦ Server Consolidation◦ Video Distribution
Results
Phone in every classroom VOIP Trunk Lines On-Net Dialing
Voice
All data traffic uses IP Each network node at least gigbit backbone
Data / Internet
No reason to have a server in the schools◦ Most servers in unconditioned closets
Brought all servers back into conditioned server farms◦ No truck rolls, backups nightly, skilled IT support
Servers
Thousands of hours of instructional “tapes” on-line
Streaming video from several internal sources
Available bandwidth for nearly 1000 fold expansion
Video
CCSD has the most advanced communication network possibly in the world
Faster, better and cheaper due to the vision of SAIC and the use of long term commitments for dark fiber
