When online state testing becomes mandatory in Florida in 2015, Chris Bress foresees school districts having their hands full simply trying to access the exams.
“If even only 50 percent of the schools statewide are testing at a time, that could be a million requests to [the Department of Education’s] server,” says Bress, executive director of learning through technology and media for Charlotte County Public Schools in Port Charlotte, FL. With so many schools fighting for a finite amount of bandwidth, trying to enter the same website at once, Bress says latency and access will be critical problems come testing season.
Although online testing won’t begin for another five years, Bress says the state is encouraging school districts to implement technology to help avert traffic jams when the time comes. “It’s going to become critical,” he says.
What bandwidth management software does is offer a window into the network, lending a real-time view of how traffic is moving about while calling attention to bottlenecks and bandwidth hogs. Armed with that information, IT staff can use the dashboard to perform a kind of bandwidth triage, “shaping,” in IT terms, bandwidth flow to make the best use of what’s available: blocking some sites, allowing total access to others, and “throttling”—enabling reduced bandwidth to—still others. That ensures proper delivery of essential web-based content while controlling the delivery of nonessential but permitted content, as determined by the district, such as social networking or gaming sites.
