Studying infrastructure deployment for a 1 to 1, specifically as devices go home.
Lessons Learned and where we are going and why.
Dallas ISD System
Off campus connection trial
New eRate Program
“To define student mobility and network options”
Dallas ISD Network Example:
Network Campus LAN,
Wireless, Data Centers,
Digital Classroom, student devices, teacher devices, guest services,
state of the art technology
Collapsed data centers down to 2 and
500 virtual servers, and 500 actual servers
Fiber upgrades…also upgraded core and LAN in data centers. 40gig in data centers and between data centers. This allows us to keep them in sync.
“In a country where we expect free wifi with our coffee, we should definitely demand it in our schools” -President Obama, June 2013.
Core of the network to the schools was like a traffic jam – 100 mbps
upgraded to 10gbps…feels like an open highway.
“There nothing special about wireless networks except that wireless capacity is sometimes less than what you can get, for example, from optical fiber.” Vint Cerf, Leading Telecommunications Architecht, MCI & Google
Dallas ISD Network diagram…two data centers. Each data center has a 5 gig connection to internet.
Data connection goes to MDF, then 10gig to IDF closets…using Cisco.
Dallas is peaking out 3gigs of their 5gigs connection.
